Summary
Long-lasting insecticide treated bednets (LLITNs) were distributed in December
2005 in Sofala and Manica provinces, Mozambique approximately two months after the
second round of the National Polio and Measles Campaign that took place in September
2005. Vouchers were distributed at the time of the immunization campaign, which were
to be redeemed later for an LLITN. We conducted a community-based cross-sectional
survey in these two provinces in February 2006, two months after the distribution of
LLITNs. This survey provided data on ownership and use of insecticide-treated bednets
(ITNs) in those provinces.
Four districts in each province and four enumeration areas (EAs) in each district
were selected using probability proportional to size. Within each EA, 32 households
(HHs) were selected using a simple random sample. We conducted interviews in each of
the selected HHs. Approximately 360,000 LLITNs were distributed as part of this
initiative. Of the selected 1024 HHs, valid interviews were completed for 947 (92.5%)
HHs (440 in Manica and 507 in Sofala). Of the participating HHs, 65.0% in Manica and
63.1% in Sofala reported at least one child less than 5 years of age and 10.2% in Manica
and 10.5% in Sofala reported at least one pregnant woman having slept in the house the
previous night. In Manica, 67.4% of HHs with at least one child under 5 years old
reported they received at least one voucher for an ITN during the registration phase in
September while in Sofala this rate was 69.3%. Of those, 91.0% HHs in Manica and
89.8% in Sofala redeemed at least one of the vouchers and received at least one LLITN.
Pre-campaign HH ownership of at least one bednet of any kind was 20.6% and
35.6% in Manica and Sofala, respectively. In addition, the equity ratio in Manica was
0.10 and in Sofala was 0.71. Post-campaign, 55.1% and 59.6% HHs owned at least one
bednet of any kind in Manica and Sofala, respectively. We found equity ratios of 0.50 in
Manica and 0.92 in Sofala. In addition, 51.5% HHs (equity ratio =0.54) in Manica and
48.5% HHs (equity ratio =0.95) in Sofala reported ownership of at least one ITN.
In Manica and Sofala, 48.1% and 47.6% of HHs respectively reported that they
had at least one ITN hanging in their HH the night before the interview date. However, in
HHs that owned at least one ITN, 89.2% in Manica and 92.4% in Sofala reported to have
3
had at least one ITN hanging the previous night. In both provinces, 60.3% of children
under 5 years old (59.3% in Manica and 61.6% in Sofala) and 39 (39%) of 100 pregnant
women reported sleeping under an ITN the previous night.
The LLITN distribution in Sofala and Manica achieved higher rates of ITN
ownership and use. It achieved the Roll Back Malaria (RBM) target of use by children
under 5 years old when Manica and Sofala provinces are combined. However, the RBM
targets of HH ownership of ITNs, and use by children in Manica alone and pregnant
women in either province were not met. In Manica, the campaign resulted in inequitable
access to ITNs, with the least poor families achieving greater access to ITNs than poorer
families. In addition, more nets were distributed than vouchers. Both of these facts call
into question the utility of voucher-based systems for integration of ITN distribution with
vaccination campaigns. Nonetheless, integration of ITN distribution with vaccination
campaigns presents an opportunity for reaching malaria control goals and should
continue to be considered for large-scale implementation.

Introduction
Malaria is endemic throughout most of Mozambique. Approximately 40% of
total outpatient complaints in Mozambique result from malaria and this figure increases
to 60% if only pediatric cases are considered. In addition, malaria is the biggest killer of
young children in Mozambique. Overall, mortality rates among children less than 5 years
old in Mozambique are estimated at 178/1000, resulting in the deaths of an estimated
170,000 children less than 5 years old each year. Malaria is thought to constitute 30% of
this figure, approximately 40,000 children yearly.
In August and September 2005, the Mozambican National Vaccination Campaign
provided measles and polio vaccination and vitamin A to children in Mozambique. Each
intervention was given according to target group ages: 0–59 months for polio, 6–59
months for vitamin A, and 9 months–14 years for measles. The campaign’s first round
happened in August 2005, when children were vaccinated against polio and measles and
received vitamin A. During the second round in September 2005, children received a
second dose of polio vaccine.
Together with the second round of the campaign, vouchers for long-lasting
insecticide-treated bednets (LLITNs) were distributed to mothers or caretakers of
children under 5 years old in the provinces of Sofala (excluding the city of Beira) and
Manica. Vouchers were limited to one per household (HH). A HH was defined as a
woman (or guardian) and her children living together. Pregnant women were not targeted
directly by this campaign. A total of 247,268 vouchers were distributed. Table 1 shows
the number of vouchers distributed by districts in the two provinces.
The Mozambican National Malaria Control Program selected the provinces of
Sofala and Manica because there were no proposals or commitments from donors for
malaria control in these two provinces. Figure 1 shows a map of Mozambique and these
two provinces are indicated. Beira was not included in the distribution because the city
was part of an indoor residual spraying program.
In December 2005, 358,331 LLITNs were distributed. Distribution posts were set
up in the provinces and, upon presentation of vouchers, LLITNs were distributed to HH
members. Table 1 shows the number of LLITNs distributed by districts in those
5
provinces. Of note, many eligible HHs that did not get a voucher in September 2005 also
received a LLITN according to the distribution criteria. To keep track of the LLITN
distribution process and avoid that a given HH would receive more than one bednet, HH
members had their index finger marked when they received an LLITN.
The primary objective of the integrated campaign was to reduce morbidity and
mortality in young children in Mozambique. Studies in Western Kenya showed that
insecticide-treated bednets (ITNs) were effective in averting approximately one in four
infant deaths in areas of intense transmission with high coverage (Phillips-Howard et al,
2003). Prior interventions in Togo, Ghana, and Zambia have shown rapid increase in
ITN ownership and use when free distribution was paired with vaccination campaigns
(Morbidity and Mortality Weekly Report, 2005; Grabowsky et al, 2005a; Grabowsky et
al, 2005b).
We present the preliminary results of the coverage survey conducted in Manica
and Sofala provinces, Mozambique in February 2006. This survey included the
following components: HH information, HH ownership of bednets and ITNs, ITN use
rate by children under 5 years old and pregnant women, and economics. These data will
provide supportive information to the ongoing efforts of the Mozambican Ministry of
Health to control malaria.
Objectives
1. Retrospectively measure pre-campaign HH ownership of bednets of any kind.
2. Measure post-campaign HH ownership of bednets of any kind and ITNs and their
use per Roll Back Malaria (RBM) target groups:
a. HHs;
b. Children under 5 years old;
c. Pregnant women.
3. Assess coverage of above by HH economic status through asset scores.

Methods
We conducted the survey from February13 to 24, 2006, approximately two
months after the LLITN distribution (December 2005). We collected information on preand post-campaign HH ownership of bednets and post-campaign ITN ownership and use.
We organized the questionnaire into five parts: HH information, bednet characteristics,
ITN use by children under 5 years old and pregnant women, and economics. A copy of
the questionnaire is attached to this report (Annex 1).
We used personal digital assistants (PDAs) (Dell Axim X50s, Dell, Austin,
Texas) in conjunction with global positioning system units (GPS) (Pharos, Torrance,
California) to conduct this survey. The PDA platform was Pocket PC 2003 SE. We
mapped all HHs in each enumeration area (EA). Descriptive information was collected at
that time to allow return to selected HHs during the navigation process. After mapping,
we chose a simple random sample of HHs among all HHs (rather than of the HHs with at
least one child under 5 years old) as the sampling unit. We then used the PDAs and GPS
devices to navigate to the selected HHs. For these steps, we used a program (GPS Survey
2.0) developed by the U.S. Centers for Disease Control and Prevention (CDC). As
previously mentioned, we included HHs with and without children in the survey.
Interviews were preprogrammed into the PDAs using Visual CE 9.1 (Syware Inc,
Cambridge, Massachusetts). We requested verbal consent from interviewees before the
survey and responses were recorded onto PDAs. All questions had pre-coded answers,
but choices were not read to respondents. Responses could be coded as ‘other’ if the
respondent’s answer did not match any of the existing responses.
Teams
We trained four teams of interviewers. Teams consisted of three to five
interviewers and one supervisor, who were regular employees of Mozambican Red Cross
or Mozambican Ministry of Health, as well as Mozambican Red Cross volunteers. Team
members were fluent in oral and written Portuguese and able to converse in other local
languages. Interviewers and supervisors were trained on the survey and technology from
February 6 to 10, 2006, just prior to the field work. Each team had a vehicle and a driver.
7
Each team went to one of the districts in Manica during the first week of the survey and
the process was repeated for Sofala during the second week.
Once in the field, team members were each accompanied by community members
who served as guides and translators for local languages. Teams mapped each EA in the
morning and gathered around midday for data merging and selection of HHs. Interviews
of selected HHs in that EA were conducted and completed during the afternoon of the
same day, thus work in each EA was finished within one day.
Definitions
For this evaluation, we defined an ITN as either an LLITN or a conventional
bednet that had been treated with insecticide within the previous 6 months. We chose the
cut off of six months because the insecticide most commonly used in Mozambique was
cyfluthrin, which has approximately 6 months of bioactivity on a bednet. Interviewers
were trained to ask to see the bednets, and to ask questions about treatment history, if
appropriate. HH ownership was based on responses from the interviewee. In addition,
we considered a bednet or ITN hung if the interviewee reported that it had been hanging
the previous night.
Study design and sample size
This study was a community-based cross-sectional survey. It used a stratified
three-stage cluster sample design. Four districts in each of the two provinces were
selected using probability proportional to size (PPS) sampling methodology. Then, we
selected four EAs in each district also through PPS. The HH was used as the primary
sampling unit. We selected a simple random sample among all the HHs mapped in each
EA. We used the same definition for HH used during the voucher and LLITN
distribution phases, i.e., a woman and her children living together. If no woman or
children lived in the HH, then the HH was defined by the man. The sampling frame for
the survey was based on the most recent census from the National Institute of Statistics of
Mozambique (1997), which divided the country in EAs. The selected districts and EAs
evaluated in this survey are listed in Annex 2.
8
The main outcome used for the sample-size calculations was the HH ownership of
ITNs after distribution. Sample-size calculations were done using the StatCalc module
(EpiInfo 2000, CDC, Atlanta). The study was designed to have at least 90% power to
estimate the proportion of HHs that received an ITN during the campaign (specified as
65%) within a range of 5% and a design effect of 1.2 per province. In total, 400 HHs
were needed in each province (25 HHs per each of the 16 EA in each province). To
cover for missing data of any cause, we increased the sample size by 25%, so a total
number of 32 HHs per EA were included in the survey.
Statistical analysis
The final data was available in Microsoft Access format. We used EPI Info 2000
(CDC, Atlanta, Georgia), Sudaan 9.0 (Research Triangle Institute, Research Triangle
Park, North Carolina), and SAS (SAS Institute, Cary, North Carolina) to analyze the data.
Statistical analysis accounted for weighting and clustering of data using appropriate
methods. All percentages presented in this report are the result of weighted analysis,
unless otherwise noted.
Population was stratified by economic score calculated according to World Bank
asset scoring for Mozambique based on the 1997 demographics and health survey. We
ordered all HHs surveyed by asset score and divided them into 5 quintiles, starting with
the 20% with the lowest scores going up to the 20% with the highest scores. Economic
equity ratio was calculated as the ratio of proportions in the poorest quintile to the least
poor quintile.
Results
HH characteristics
In Manica, a total of 440 HHs were surveyed. The number of mapped and
interviewed HHs per district is shown in Table 2. The median number of total persons,
children, and pregnant women who slept at the HH the night before was 3 (range: 0–12),
1 (range: 0–5), and 0 (range: 0–2), respectively. HHs had a median number of 2 sleeping
spaces (range: 1–6) used the previous night.
9
A total of 507 HHs were surveyed in Sofala province (Table 2). The median
number of total persons, children, and pregnant women sleeping at the HH the night
before was 3 (range: 0–12), 1 (range: 0–3), and 0 (range: 0–2), respectively. HHs had a
median number of 2 sleeping spaces (range: 1–6) used on the night before.
Campaign
Among the 947 HHs interviewed, 48.3% in Manica and 48.2% in Sofala received
at least one voucher at the vaccination post in September 2005. Forty-six HHs received
more than one voucher. Of HHs with or without a child under 5 years old that received at
least one voucher, 88.9% in Manica and Sofala presented at least one of these vouchers
and received a LLITN. The most common reasons for not redeeming the vouchers were
losing the voucher and not knowing when and/or where to redeem it in Manica; and, in
Sofala, those reasons were losing the voucher and lines too long. In Manica, 29 HHs
received at least one campaign LLITN without presenting a voucher, but our analysis
revealed that 26 of these had at least one child under 5 years old living in the HH. In
Sofala, 22 HHs received at least one campaign LLITN without presenting a voucher, but
our analysis revealed that 19 of these had at least one child under 5 years old living in the
HH.
Once we restricted the analysis to the HHs with at least one child under 5 years
old (the target group for this distribution), we observed that 67.4% of HHs in Manica and
69.3% in Sofala had received at least one voucher during the campaign. In addition,
91.0% of HHs that had at least one child under 5 years old and received at least one
voucher redeemed at least one of them in Manica, while in Sofala, this ratio was 89.8%.
Within our sample in Manica, in addition to the 210 LLITNs distributed upon
presentation of a voucher, 28 (11.8%*) LLITNs were distributed without the presentation
of a voucher. In Sofala, 27 (10.7%*) LLITNs were distributed without the presentation of
a voucher in addition to the 225 distributed upon presentation of a voucher.

10
Post-campaign visits by a Mozambican Red Cross volunteer discussing the
importance and benefits of ITN use was conducted in 26.1%* and 57.2%* of HHs in
Manica and Sofala, respectively.
Children under 5 years old
In Manica, a total of 407 children under 5 years old were included in the survey.
The median age of these children was 20 months (range: 1–60) and 207 (50.9%*) were
female. In Sofala, we included a total of 447 children under 5 years old. The median age
of these children was 24 months (range: 1–60) and 233 (52.1%*) were female.
Among all children under 5 years old, 88.7% and 86.6% went to a vaccination
post in September in Manica and Sofala, respectively. Moreover, 59.9% of children
under 5 years old in Manica and 53.3% in Sofala received a voucher. Reasons for not
receiving a voucher are listed in Table 3. Finally, 51.6% and 45.4 % of mothers or
caretakers of children under 5 years old went to the distribution post in November or
December 2005 and received an LLITN from the campaign in Manica and Sofala,
respectively.
Considering the children under 5 years old in Manica and Sofala, 59.3% and
61.6% slept under an ITN the previous night, respectively. Distribution per district is
shown in Table 4. When data from both provinces are combined and weighted, 60.3% of
all children under 5 years old slept under an ITN the previous night.
Pregnant women
A total of 100 pregnant women were included in our survey (46 from Manica and
54 from Sofala). In Manica, 32.6%* slept under an ITN the previous night, while in
Sofala this ratio was 44.4%.* For both provinces combined, this ratio was 39%.* Due to
the small sample of pregnant women, a valid confidence interval for this indicator could
not be calculated.

Net specifics
Among 440 HHs in Manica, 55.1% (95% confidence interval [CI]: 43.6–66.1)
had at least one bednet of any kind and we collected information on 309 bednets of any
kind. Of these bednets, 279 (90.4%; 95% CI: 82.2–95.0) were ITNs. Among all ITNs,
256 (91.8%*) were campaign LLITNs and 23 (8.2%*) were ITNs of other origin. Among
the 23 noncampaign ITNs, 11 (47.8%*) were LLITNs and 12 (52.2%*) were regular
bednets that were treated with insecticide within the previous 6 months. Two hundred
twenty-six (51.5%; 95% CI: 41.3–61.5) HHs had at least one ITN. Of all ITNs included
in the sample in Manica, 91.0% (95% CI: 85.3–94.6) were reported to have been hanging
the night before the survey.
Among 507 HHs in Sofala, 59.6% (95% CI: 42.4–74.7) had at least one bednet.
We collected information on 369 bednets of any kind. Of those bednets, 279 (75.9%;
95% CI: 70.0–80.8) were ITNs. Among all ITNs, 249 (89.2%*) were campaign LLITNs
and 30 (10.8%*) were ITNs of other origin. Among the 30 noncampaign ITNs in Sofala,
18 (60.0%*) were LLITNs and 12 (40.0%*) were regular bednets that were treated with
insecticide within the previous 6 months. Two hundred forty-three (48.5%; 95% CI:
34.8–62.4) HHs had at least one ITN. Of all ITNs included in the sample in Sofala,
96.6% (95% CI: 92.6–98.5) were reported to have been hanging the night before the
survey.
ITN ownership, use, and equity
In Manica, pre-campaign HH ownership of at least one bednet of any kind was
20.6% (95% CI: 8.0–43.6). In addition, pre-campaign HH ownership was lower in the
poorest quintile (5.7% [95% CI: 1.3–21.8]) compared to the least poor quintile (55.7%
[95% CI: 43.0–67.8]) with an equity ratio of 0.10. Post-campaign HH ownership of at
least one bednet increased to 55.1% (95% CI: 43.6–66.1). Post-campaign HH ownership
in the poorest quintile was 41.2% (95% CI: 19.3–67.4) compared to 82.3% (95% CI:
68.9–90.7) in the least poor quintile with a higher equity ratio (0.50) (Figure 2).

Percentage not weighted.
12
Pre-campaign HH ownership of at least one bednet of any kind per HH was
35.6% (95% CI: 27.8–44.3) in Sofala. Pre-campaign HH ownership was lower in the
poorest quintile (27.9% [95% CI: 20.3–37.0]) compared to the least poor quintile (39.4%
[95% CI: 27.8–52.2]) with an equity ratio of 0.71. Post-campaign HH ownership of at
least one bednet increased to 59.6% (95% CI: 42.4–74.7). Post-campaign HH ownership
in the poorest quintile was 52.2% (95% CI: 22.7–80.3) compared to 56.6% (95% CI:
45.2–67.2) in the least poor quintile with a higher equity ratio (0.92). These results are
summarized in Figure 2.
Post-campaign HH ownership of an ITN was 51.5% (95% CI: 41.3–61.5) in
Manica. Post-campaign HH ownership of ITNs in the poorest quintile was 40.3% (95%
CI: 19.9–64.7) compared to 74.3% (95% CI: 62.0–83.8) in the least poor quintile with an
equity ratio of 0.54. Similarly, HH post-campaign ownership of an ITN was 48.5% (95%
CI: 34.8–62.4) in Sofala. Post-campaign HH ownership of ITNs in the poorest quintile
was 42.9% (95% CI: 24.8–63.1) compared to 45.3% (95% CI: 38.3–52.5) in the least
poor quintile with an equity ratio of 0.95. These results are summarized in Table 5 and
Figure 3.
Once we restrict the analysis to bednets distributed during the campaign, we
observed that HH ownership of at least one campaign LLITN was 48.6% (95% CI:
38.1%–59.1) in Manica. In addition, HH ownership of campaign LLITNs in the poorest
quintile was 38.5% (95% CI: 19.4–62.0) compared to 68.0% (95% CI: 56.1–77.9) in the
least poor quintile with an equity ratio of 0.57. In contrast, ownership of a campaign
LLITN was 43.5% (95% CI: 32.2–55.6) in Sofala. HH ownership of campaign LLITNs
in the poorest quintile was 40.1% (95% CI: 24.5–58.0) compared to 40.4% (95% CI:
30.9–50.6) in the least poor quintile with an equity ratio of 0.99. These results are
summarized in Table 6 and Figure 4. Data on HH ownership of noncampaign ITNs is
summarized in Table 7.
In Manica, 48.1% (95% CI: 36.9–59.5) of HHs reported at least one ITN hanging
the previous night (Table 8). When HHs that owned at least one ITN were considered,
this ratio was 89.2% (95% CI: 84.0–92.9) (Table 9). In Sofala, 47.6% (95% CI: 33.8–
61.7) of HHs reported at least one ITN hanging the previous night and, when HHs that
13
owned at least one ITN were considered, this ratio was 92.4% (95% CI: 85.9–96.0)
(Tables 8 and 9). In addition, 96.5% (95% CI: 93.9–98.0) of HHs that had at least one
campaign LLITN reported to had at least one of them hanging the previous night in
Manica, while in Sofala this ratio was 98.7% (95% CI: 97.4–99.3).
Post-campaign use of ITNs by children under 5 years old was 59.3% (95% CI:
54.4–63.9) in Manica: 48.4% (95% CI: 26.9–70.5) in the poorest economic quintile and
71.9% (95% CI: 65.6–77.5) in the least poor quintile. The equity ratio for children under
5 years old ITN use was 0.67. Data on children under 5 years old per economic quintile
are summarized in Table 10 and Figure 5. When children who lived in a HH that owned
at least one ITN (251 children) are considered, 96.7% (95% CI: 86.0–99.3) slept under an
ITN the previous night in Manica.
Post-campaign use of ITN by children under 5 years old was 61.6% (95% CI:
41.2–78.6) in Sofala: 54.5% (95% CI: 20.7–84.6) in the poorest economic quintile and
61.6% (95% CI: 54.3–68.3) in the least poor quintile. The equity ratio for children under
5 years old use was 0.88 (Table 10 and Figure 5). When children who lived in a HH that
owned at least one ITN (285 children) are considered, 95.7% (95% CI: 93.7–97.1) slept
under an ITN the previous night in Sofala.
Discussion
This survey was designed to evaluate ITN coverage following the distribution of
free LLITNs in Manica and Sofala provinces. Vouchers were distributed as part of the
second round of polio vaccination and were to be redeemed for LLITNs approximately
two months after the campaign. High coverage with ITNs has been shown to reduce
malaria morbidity and all cause mortality in endemic areas (Phillips-Howard PA et al,
2003). By providing LLITNs to children under 5 years old, the campaign was intended
to increase HH ownership and use of ITNs in these two provinces. Moreover, increasing
ITN ownership among HHs with children under 5 years old may benefit the whole
community. Prior studies have shown that increasing community levels of ITN use to
>50% is beneficial in reducing mosquito populations and malaria (Maxwell CA et al,
2002; Hawley WA et al, 2003).

Our survey showed that 88.7% and 86.6% of children under 5 years old in Manica
and Sofala, respectively, went to a vaccination post in September 2005. Additionally,
approximately 50% to 60% of mothers or caretakers of children under 5 years old
received vouchers for LLITNs and indeed redeemed the vouchers for LLITNs at a later
time. Upon comparison of the number of vouchers and LLITNs distributed provided by
registration and vaccination teams, we observed that a high percentage of nets were
distributed even in the absence of a voucher. However, our survey results showed only
10% of nets were received without a voucher. This observation, coupled with the
inequitable post-campaign LLITN observed in Manica, makes us question the value of
distributing vouchers during vaccination campaigns instead of distributing the nets
directly at a later time. However, combining either vouchers distribution with
vaccination campaigns might make microplanning, social mobilization, and logistics
more efficient, thereby saving funds and perhaps ultimately contributing to higher
coverage rates than distributing ITNs directly not connected to a vaccination campaign.
Results of this cross-sectional survey showed that the 2005 campaign to distribute
LLITNs to HHs with children under 5 years old rapidly achieved higher levels of ITN
ownership in Manica and Sofala, Mozambique when compared to pre-campaign figures.
Our data suggest that this was achieved more equitably in Sofala than in Manica. Precampaign HH ownership of bednets were more inequitably distributed in Manica (equity
ratio=0.10) than in Sofala (equity ratio=0.71). Moreover, HH ownership of campaign
LLITNs was also less equitable in Manica than in Sofala, possibly a result of less
effective and equitable distribution efforts in the two provinces.
HH ownership of bednets increased from 20.6% to 55.1% in Manica with
increased equity ratios. In Sofala, HH ownership of bednets increased to around 60%
also with higher equity ratios. Approximately 65% of HHs had at least one child under 5
years old. This proportion is lower than that of Togo (72.8%) or Niger (79.3%) and may
explain why lower community HH ownership of LLITNs was observed in these two
provinces post-campaign when compared to Togo and Niger, since only HHs with
children under 5 years old were targeted for distribution (Wolkon A et al, 2005;
Hochberg N et al, 2005).
15
We were unable to assign the insecticide treatment status of bednets present in the
HH prior to the campaign. However, taking into account the percentages of ITNs among
noncampaign bednets at the time of the survey (43.4% [23 ITNs/53 bednets of any kind]
for Manica province), we can estimate the pre-campaign HH ownership of ITNs to be
8.9% (20.6% x 43.4%) in Manica, lower than what was observed post-campaign. These
findings are consistent with previous studies in the literature, which suggest that
integrated campaigns to distribute ITNs are able to increase HH ownership of ITNs
(Grabowsky M et al, 2005a; Grabowsky M et al, 2005b; MMWR 2005). Similar
reasoning can be done for Sofala province, with higher equity ratios.
In addition, we found high rates of ITN use among HHs that owned at least one
ITN. We also observed that, among HHs that received at least one campaign LLITN,
more than 95% reported at least one of those hanging the previous night. This is higher
compliance than that observed in Togo, where comparable indicators were measured
(Wolkon A et al, 2005). This may be in part attributed to the work done by volunteers
involved in social mobilization, voucher and LLITN distributions, and post-campaign
follow-up visits. It may also partly reflect a self-selection bias since HH members who
made the extra trip to obtain a campaign LLITN may have been more likely to hang it.
Moreover, the survey was conducted late in the rainy season, with possible increase in
mosquito population, a factor known to increase use of bednets.
Regarding use by children under 5 years old (campaign and RBM target group),
we noticed that use rates for both provinces combined is above the 60% RBM target. In
addition, compliance rates (children sleeping under an ITN given at least one ITN in the
HH) were above 95%. In comparison, a survey in Togo during the rainy season, 9
months after the distribution found 69.5% utilization given at least one ITN in the HH
(Wolkon A et al, 2005). Again, this difference may be attributed to increased follow-up
visits and/or mosquito burden.
Given the cross-sectional design of the survey, we were unable to understand how
ITN ownership and use may vary over time. Moreover, our evaluation was focused on
the end results of the campaign, i.e., ITN ownership and use, but provided little
information about improving the overall process of the campaign. Analysis of the
16
campaign itself may yield important lessons for improving future distribution strategies.
In addition, the findings were compared to RBM targets, which are indicators for
countries, rather than country sub-regions as we presented here.
In conclusion, the LLITN distribution in Sofala and Manica appears to have been
an effective strategy to rapidly scale up ITN ownership and use. The figures for HH
ownership of ITNs, although encouraging, are below the RBM targets and efforts to
achieve higher rates should be encouraged. The overall project did achieve the RBM
target for ITN use by children under 5 years old when the provinces were combined, but
only for Sofala when data from each province is analyzed separately. Integration of ITNs
with vaccination campaigns presents an important opportunity for reaching malaria
control goals and should be considered for large-scale implementation.
