The World Health Organization (WHO) has issued an alert over four cough and cold syrups made by Maiden Pharmaceuticals in India, warning they could be linked to the deaths of 66 children in the Gambia.
The UN health agency also cautioned the contaminated medications may have been distributed outside the West African country, with global exposure "possible".
WHO chief Tedros Adhanom Ghebreyesus told reporters the four cold and cough syrups in question "have been potentially linked with acute kidney injuries and 66 deaths among children".
Those substances are toxic to humans and can be fatal, it said, adding that the toxic effect "can include abdominal pain, vomiting, diarrhea, inability to pass urine, headache, altered mental state and acute kidney injury which may lead to death".
