New malaria cases transmitted within the United States have raised alarm bells among health officials.
In 2021, there were around 247 million cases of malaria worldwide, and an estimated 619,000 people died from the disease, according to the World Health Organization (WHO). Around 95 percent of cases occur in Africa, and more than half of malaria deaths in 2021 were concentrated in four countries: Nigeria, the Democratic Republic of the Congo, Tanzania and Niger. Most deaths are in children under the age of five. Disruptions in controlling malaria caused by the Covid-19 pandemic have led to a rise in cases and deaths in the past couple of years.
