Sri Lanka’s health minister, who has faced criticism for consuming and endorsing a herbal syrup made by a sorcerer, has tested positive for Covid-19.

A Health Ministry official on Saturday confirmed that Pavithra Wanniarachchi became the highest-ranking official to be infected with the virus.

She and her immediate contacts have been asked to self-quarantine.

Doctors have said there is no scientific basis for the syrup as remedy for the coronavirus.

It's said to contain honey and nutmeg.

Thousands of people gathered in long queues in December in the town of Kegalle, northeast of the capital Colombo, to obtain the syrup, just days after Wanniarachchi and several other government officials publicly consumed it.

The maker of the syrup said he got the formula through his divine powers.

Meanwhile on Saturday, President Gotabaya Rajapaksa announced that Sri Lanka will receive the first stock of Oxford-AstraZeneca vaccine from India on January 27.

He said India is giving this stock free of charge and his government is making arrangements to purchase more vaccines from India, China and Russia.

On Friday, Sri Lanka approved the Oxford-AstraZeneca vaccine amid warnings from doctors that front-line health workers should be quickly inoculated to prevent the medical system from collapsing.

The vaccine was the first to be approved for emergency use in Sri Lanka.

The Health Ministry says the inoculation will begin by mid-February.

Sri Lanka has reported 52,964 cases with 278 fatalities. (AP)
