According to new research, presented on 18th November at the annual meeting of the American Society of Tropical Medicine and Hygiene , even a small number of infected children can transmit malaria parasites to a mob of mosquitoes, which can then go on to infect more humans.

From their new research in Uganda, the researchers concluded that asymptomatic children between ages 5 and 15 are the main source of infection for local mosquitoes in the region they studied. Some of these children were so-called superspreaders. In experiments where mosquitoes were fed blood samples from infected people, more than 60% of the resulting mosquito infections could be traced back to just four asymptomatic children, two of whom were school-age.

The team also analyzed the density of gametocytes in the human blood samples, as the number can hint at how infectious that blood might be to mosquitoes.

Over the course of the study, the team detected 148 episodes of malaria 38 symptomatic and 110 asymptomatic. The team later dissected the fed mosquitos to see how many became infected, and the vast majority of infections were linked to blood from asymptomatic people.

Overall, the researchers estimated that children ages 5 to 15 represent nearly 57% of the infectious reservoir, meaning they carry most of the parasites that could infect mosquitoes with malaria.
