As the coronavirus death toll continues to rise, some have suggested that the approaching warmer spring weather in the northern hemisphere may slow or even stop the spread of the disease. US president echoed this, saying: “The heat, generally speaking, kills this kind of virus.” But is he right?

The idea that the approaching spring may stem the spread of the disease comes largely from a comparison with the flu. In many ways COVID-19 is like the flu – both spread in similar ways (respiratory secretions and contaminated surfaces) and both cause typically mild respiratory diseases that can develop into life-threatening pneumonia. But the transmissibility and severity of COVID-19 are much greater than the flu. And it isn’t clear if COVID-19 transmission will be affected by seasonal temperature variation.
