Some London buses are reportedly being converted into ambulances as the city grapples with a devastating COVID-19 outbreak.

The Guardian reported Thursday that bus company Go-Ahead loaned the vehicles to the National Health Service and will provide four drivers, who have been vaccinated against the virus. 

But the NHS denied that at least two single-decker buses were renovated to transport patients.

“The buses aren’t actually being used by the NHS and there aren’t any plans to use them,” a spokeswoman for the agency’s London offices told The Post.

Doctors and nurses, as well as volunteer paramedics from the St. John Ambulance charity, will apparently be on board to treat patients, the outlet reported.

The vehicles will be equipped with oxygen and infusion pumps in order to keep patients stable until they can be admitted to one of the capital’s hospitals.

The converted buses are expected to be put into use in the next few days, the Guardian reported.

The initiative is aimed at relieving pressure on ambulance crews, who have been inundated with emergency calls following the arrival of a new, more contagious strain of the virus, the outlet reported.

More than 4,000 Londoners currently are hospitalized with the virus, according to the latest NHS figures.

Prime Minister Boris Johnson on Jan. 2 ordered the country into a lockdown to slow infections and prevent the NHS from being overwhelmed.
