Asymptomatic children can spread Malaria

Date: 21 November 2020 Tags: Miscellaneous


Children infected with malaria can become "super-spreaders" and pass the parasite to local mosquitoes, even if the kids never develop symptoms of the disease.



If malaria goes untreated in these asymptomatic children, the parasites will continue to circulate among mosquitoes.



  • 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.

  • Despite some children becoming infected with multiple malaria clones during the study, these kids never fell ill and continued to lead a normal life.

  • While scientists agree that mosquitoes pick up malaria from both symptomatic and asymptomatic people, there's a question as to whether one kind of infection is more or less infectious than the other.

  • The challenge becomes identifying infected people without symptoms, so that their chains of transmission can also be broken.

  • 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.



  • Malaria disease is caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes.

  • While the disease is uncommon in temperate climates, malaria is still common in tropical and subtropical countries. The severity of malaria varies based on the species of plasmodium.

  • Symptoms are :

  • Fever

  • Chills

  • Headache

  • Nausea and vomiting

  • Muscle pain and fatigue
