As the malaria season begins in southern Africa, COVID-19 complicates the picture

As the malaria season begins in southern Africa, COVID-19 complicates the picture

HEALTH
TWO of the nine global public health awareness days are associated with malaria: World Malaria Day, observed on 25 April, and World Mosquito Day, which commemorates the discovery by Sir Ronald Ross on 20 August 1897 that Anopheles mosquitoes transmit malaria parasites to humans. JAISHREE RAMAN, Laboratory for Antimalarial Resistance Monitoring and Malaria Operational Research, National Institute for Communicable Diseases SHÜNÉ OLIVER, medical scientist , National Institute for Communicable Diseases Both World Malaria Day and World Mosquito Day are particularly relevant to Africa. The continent shoulders the greatest burden of malaria globally. Ninety-three percent of the 228 million malaria cases…

Invasive mosquito species could bring more malaria to Africa’s urban areas

HEALTH
JEREMY HERREN, Scientist, International Centre of Insect Physiology and Ecology CLIFFORD MUTERO, Consultant Scientist, International Centre of Insect Physiology and Ecology A species of mosquito that can carry malaria – known as Anopheles stephensi – has invaded eastern Africa and is quickly moving across the region. Moina Spooner, from The Conversation Africa, asked Jeremy Herren and Clifford Mutero to provide insights into why this invasion is happening and what can be done to protect people from it. How did Anopheles stephensi come to Africa? This mosquito species, Anopheles stephensi, is widespread in South-East Asia and parts of the Arabian Peninsula.…

Neanderthal genes linked to severe COVID-19; Mosquitoes cannot transmit the coronavirus

Neanderthal genes linked to severe COVID-19; Mosquitoes cannot transmit the coronavirus

SCIENCE, TECH AND INNOVATION
NANCY LAPID  THE following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. Neanderthal genes linked with severe COVID-19 A group of genes passed down from extinct human cousins is linked with a higher risk for severe COVID-19, researchers say. When they compared the genetic profiles of about 3,200 hospitalized COVID-19 patients and nearly 900,000 people from the general population, they found that a cluster of genes on chromosome 3 inherited from Neanderthals who lived more than 50,000 years ago…
