13.1.2 Use <strong>of</strong> Mosquito Nets by Children<br />

Age is an important factor in determining levels <strong>of</strong> acquired immunity against malaria. For<br />

the first six months <strong>of</strong> life, antibodies acquired from the mother during pregnancy protect children<br />

from malaria. Upon weaning, this immunity is gradually lost, <strong>and</strong> children start developing their own<br />

immunity over a period <strong>of</strong> time. Unlike immunity for some other infectious diseases, immunity<br />

against malaria is not permanent, <strong>and</strong> protection from infection requires the regular use <strong>of</strong> protective<br />

interventions. ITNs confer some protection if used regularly.<br />

In the <strong>2009</strong>-<strong>10</strong> TLDHS, respondents to the Household Questionnaire were asked about the<br />

use <strong>of</strong> mosquito nets by all members <strong>of</strong> the household the night before the interview. Table 13.2<br />

presents information on the use <strong>of</strong> mosquito nets by children under age 5 in all households, <strong>and</strong> in<br />

households with an ITN, by background characteristics. The results show that 45 percent <strong>of</strong> children<br />

under age 5 in all households slept under a treated or untreated mosquito net the night before the<br />

survey, <strong>and</strong> 41 percent slept under an ITN. In households that own at least one ITN, more than four in<br />

five children (83 percent) slept under an ITN.<br />

Table 13.2 Use <strong>of</strong> mosquito nets by children<br />

Among children under five years <strong>of</strong> age in all households, the percentages <strong>of</strong> children under five years <strong>of</strong> age who slept the<br />

night before the survey under a mosquito net (treated or untreated), under an ever-treated mosquito net, <strong>and</strong> under an<br />

insecticide-treated net (ITN), <strong>and</strong> among children under five years <strong>of</strong> age in households with at least one ITN, the percentage<br />

who slept the night before the survey under an ITN, by background characteristics, <strong>Timor</strong>-<strong>Leste</strong> <strong>2009</strong>-<strong>10</strong><br />
