Nigeria says more than half of Kano's mysterious deaths due to COVID-19.
As many as 60 percent of the "mysterious" deaths in Nigeria's northern Kano state were likely due to the new coronavirus, the government's health minister said.
Nigeria's tCOVID-19 ask force sent a team to the northern economic hub in late April to investigate and conduct "verbal autopsies" after local newspaper the Daily Trust reported a spike in deaths to around 150 people in Kano city.
Minister of Health Osagie Ehanire said the investigation found a total of 979 deaths recorded in eight municipal local government areas in Kano state at a rate of 43 deaths per day, compared with the typical death rate of roughly 11 deaths per day.
"With circumstantial evidence as all to go by, investigation suggests that between 50-60 percent of the deaths may have been triggered by or due to COVID-19, in the face of pre-existing ailments," Ehanire said.
He said the peak in deaths occurred in the second week of April, and that by the beginning of May, the death rate had gone back down to the normal rate.
COVID-19 may have been spreading in China in August: Harvard research.
The novel coronavirus might have been spreading in China as early as August 2019, according to Harvard Medical School research based on satellite images of hospital travel patterns and search engine data.
The research used high-resolution satellite imagery of hospital parking lots in Wuhan - where the disease emerged 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."
"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.
It showed a steep increase in hospital parking lot occupancy in August 2019.
"In August, we identify a unique increase in searches for diarrhoea which was neither seen in previous flu seasons or mirrored in the cough search data," according to the research.
