Summary

Background:

Malaria is caused by parasites carried by some mosquitos. When the mosquitos bite people, the parasites can infect them. One of these parasites is Plasmodium vivax (P. vivax). Some children have P. vivax in their blood. They did not have malaria symptoms, but some also had a blood problem called anemia. This can make people feel tired or weak. This could have been caused by P. vivax. Researchers want to know how P. vivax infects these children, and if it affects their health.

Objective:

To collect blood, stool, and urine monthly from children to look for infections with P. vivax, worms, and other parasites.

Eligibility:

Children between 6 months and 10 years old

Design:

For screening, the study will be explained to the participant s parents or guardians, who will provide consent.

Participants will have a visit once a month for about 3 months, from November to January, and then for about 6 months from June to November 2018. Visits include:

Questions about their health

Medical history

Physical exam

Blood draw by pricking the finger tip

Urine and stool collection. They may collect these at home and bring them back.

If participants have P. vivax in their blood, them may need to come back to the clinic within 3 days. They will have blood taken from their arm using a needle.

If participants feel ill during the study, they can go to the clinic for an exam and blood tests.

If participants develop malaria while on the study, they will be treated.

Participants samples will be stored for future research studies.
