Satellite maps in recent days have shown alarming levels of SO2 around Wuhan, the Chinese city where the outbreak began.

In addition, there were high sulphur dioxide levels in the city of Chongqing which is also under quarantine.

Scientists say that sulphur dioxide is produced when bodies are cremated, and also when medical waste is incinerated.

But social media users who investigated the maps have suggested that dead bodies could be being burned on the outskirts of the city.
