To halt malaria transmission, more research focused on human behavior – ScienceDaily


Wherever possible, researchers should not only focus on migraine behavior, but also must be seen how humans behave at night when the infected mosquito is the highest, new findings from the Johns Hopkins Center for Communication Programs ( CCP) suggest. CCP is based at the Johns Hopkins Bloomberg School of Public Health.

A CCP-led review article published in Malaria Journal Last week finds that while there is a substantial research into malaria mosquitoes, when they are most active and which species are most likely to spread disease, there is very little that considers the other side of the equation: people.

"The neglected piece has really been human behavior," says April Monroe, MSPH, Senior Program Officer at CCP and who led the research. "There's been a big focus on mosquito behavior but you have to look at mosquitoes and people to really understand what is going on and how to reduce malaria risk."

Insecticide-treated bed nets are the leading cause why there has been a significant reduction in malaria over the last 15 years, with a 41-percent decrease in malaria rates and a 62-percent decrease in malaria deaths. But bed nets only work when people sleep under them.

While studies have shown that most people who have nets use them, there are times when malaria mosquitoes are biting when it is not possible to use a net. These include while doing home and christian louboutin sale, as well as during outdoor safety, and while attending community events such as funerals, weddings or religious events which can last throughout the night .

"Insecticide-treated nets are our best tool for preventing malaria right now, but we also know that nets alone will not be enough to bring the number of malaria cases to zero," Monroe says. "While the nets will remain crucial for years to come, we must also provide the appropriate solutions to people where they and when they need it."

For their review, the researchers screened nearly 3,000 peer-reviewed articles and analyzed 26 that provided information on when and where people are exposed to malaria-transmitting mosquitoes and what nighttime activities when mosquitoes are most active.

After conducting the review, Monroe and her colleagues recommend that researchers use a standardized approach to measuring both human and mosquito behavior across time and settings. This information, she says, is essential for targeting existing tools, social and behavior change interventions and the development and deployment of prevention tools to complement bed nets and indoor spraying.

"People are still getting malaria, even in places where there is broad use of bed nets," Monroe says. "We need to fill these research gaps and make decisions on how to better people. A greater understanding of human behavior and the mosquitoes is crucial if we are going to eliminate malaria."
