As researchers work to eliminate malaria worldwide, new strategies are needed to find and treat individuals who have malaria, but show no signs of the disease. The prevalence of asymptomatic or minimally symptomatic malaria can be as high as 35 percent in populations with malaria and these asymptomatic individuals can serve as a reservoir for spreading malaria even in areas where disease … [Read more...]
Contrasting Patterns of Malaria Drug Resistance Found Between Humans and Mosquitoes
A recent study has detected contrasting patterns of drug resistance in malaria-causing parasites taken from both humans and mosquitoes in rural Zambia. Parasites found in human blood samples showed a high prevalence for pyrimethamine-resistance, which was consistent with the class of drugs widely used to treat malaria in the region. However, parasites taken from mosquitoes themselves had very … [Read more...]
