COVID-19 Informer: Coronavirus active since August according to Harvard research

Coronavirus active since August: Harvard research

Coronavirus might have been spreading in China as early as August last year according to Harvard Medical School research.

The research used satellite imagery of hospital parking lots in Wuhan, where the disease was first identified in late 2019, and data for symptom-related queries on search engines for things such as "cough" and "diarrhoea".

"Increased hospital traffic and symptom search data in Wuhan preceded the documented start of the SARS-CoV-2 pandemic in December 2019," according to the research.

"While we cannot confirm if the increased volume was directly related to the new virus, our evidence supports other recent work showing that emergence happened before identification at the Huanan Seafood market (in Wuhan)."

"These findings also corroborate the hypothesis that the virus emerged naturally in southern China and was potentially already circulating at the time of the Wuhan cluster," according to the research.

The World Health Organisation has been looking into when coronavirus patients are most infections, and have found its just at the point when they first feel unwell.

WHO experts said that's made it hard to control the spread of the virus, but it can be done with testing and social distancing.
