India is investigating the deaths of dozens of children in the Gambia, which the World Health Organization says may be linked to an Indian-made cough syrup, two Indian health ministry sources told Reuters.

WHO Director-General Tedros Adhanom Ghebreyesus told reporters that the organization is investigating deaths from acute kidney failure with the regulator in India and New Delhi-based Maiden Pharmaceutical, a cough syrup maker.

Two sources indicated that the organization informed the Comptroller General of Narcotics in India of the deaths late last month, after which the regulator opened an investigation with state authorities in connection with the investigation by the World Health Organization.

Two sources indicated that the company only produced and exported the drink to the West African country.

The two sources said the Indian government has asked the World Health Organization to share its report on the association of deaths with cough syrup and will take “all necessary steps in this regard.”
