Summary

Background:

Some mosquitos carry viruses that can cause disease. Some examples are dengue and Zika. The mosquitos spread disease by biting people and infecting them with the virus. Children, elderly people, and people who are already sick are especially likely to get infected. Researchers want to learn more to help make new medicines to treat these viral infections.

Objective:

To learn more about how mosquitos infect people, and why young children are more likely to get sick than other people.

Eligibility:

Healthy children 2-9 years old who live near the study site. This is Kampong Speu District Referral Hospital in Chbar Mon, Cambodia.

Design:

At visit 1, participants will have a physical exam. A small amount of blood will be taken from their arm or finger. Parents will answer questions about the participant s general health and medical history.

Participants will come back to the study site every wet season and every dry season for the next 3 years. The visits will be the same as visit 1 and take about 1 hour.

If at any time during the study the participant gets a fever and has other symptoms that could be caused by these viral diseases, they should be brought to the study site. These symptoms might include headache, pain behind the eyes, muscle pain, or joint pain. They can also include a rash that lasts longer than 12 hours.

Participation ends after the final study visit in late 2021.
