Britain is putting 8.4 million pounds ($10.49 million) into a new study to examine the long-term effects of Covid-19 on patients, the health ministry said on Sunday.

The novel coronavirus which causes Covid-19 has been observed to cause many health impacts for some patients beyond immediate respiratory issues, but with other infected people asymptomatic, the workings of the virus are not fully understood.

“As we continue our fight against this global pandemic, we are learning more and more about the impact the disease can have, not only on immediate health, but longer-term physical and mental health too,” health minister Matt Hancock said.

The Department of Health said 10,000 people would take part in the study, which is being led by the University of Leicester and hospitals in the city.

Lung and blood samples of the patients will be taken and they will also be assessed by advanced imaging, and the findings will be used to develop new forms of personalised treatment.
