The pandemic has made a lot of bad things worse, but South Africa’s near-total lack of a flu season stands out as a big, and positive, exception. Instead of the 1,000 or more cases of flu in a normal flu season, South Africa this year has only one reported case. From New Zealand to Australia, Argentina, Chile and South Africa, reported cases of flu have sharply decreased. Measures taken to protect against Covid-19, including mask wearing and school closures, are thought to be the cause of decreased flu transmission. School closures seem to have interrupted the whole transmission chain. The lack of flu in the Southern Hemisphere may mean that the Northern Hemisphere can also avoid a flu season.
