Condition: Malaria · Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)
Background: Malaria is a disease caused by parasites transmitted to people by mosquitoes. Around the world, there were 241 million cases and 627,000 deaths from malaria in 2020. Researchers are working to develop vaccines and treatments for this disease. Objective: To learn how malaria develops in people; how the body's immune system reacts to malaria; and how malaria spreads from people to mosquitoes. Eligibility: Healthy people in the Washington DC area, aged 18 to 54 years. They cannot live alone during parts of the study. Design: Participants will be infected with a parasite that causes malaria. The parasite will be in donated blood; it will be given through an IV. Participants will likely develop symptoms within a week after the injection. Researchers will call daily to check on their health. After about 6 days, participants will come to the NIH clinic each day for blood tests. Participants will check in to the NIH clinic around 10 days after the injection. They will stay in the clinic 3 to 6 days. They will have multiple blood tests every day. Participants will be bitten by mosquitoes up to 4 times. Cups containing mosquitoes will be held against their skin for 15 minutes. Participants will begin taking chloroquine close to the end of their clinic stay. Chloroquine is a pill taken by mouth once or twice a day for 3 days. It is FDA-approved to treat malaria. Participants will have follow-up visits 1 and 3 weeks after discharge.
