Children at greater risk of dengue infection
The children who are more than six years are at a greater risk of dengue infection since they spend more time in crowded places like schools and parks, says a new study.
Under the study, two household serosurveys were led in 2012 to assess the seroprevalence and seroincidence of dengue fever virus (DENV).
During the period, information on demographic, socioeconomic and other relevant characteristics were collected from the study participants using a structured socioeconomic questionnaire. The findings have been released recently.
The study combines serological surveys of blood samples with participant interviews to determine various sociocultural risk factors that predict DENV infection.
Serological surveys measure the presence of circulating antibodies in blood samples to objectively determine whether each participant has been infected with DENV in the past.
