A key malaria treatment has failed for the first time in patients being treated in the UK, doctors say.
The drug was administer on the four patients.the four patient have previously visited Africa, in early signs the parasite is evolving resistance.
A team at the London School of Hygiene and Tropical Medicine said it was too early to be scared or panic about.However things might get deteriorate and it needs urgent appraisal of drug-resistance levels in Africa.
Malaria parasites are spread by bites from infected mosquitoes,this disease kill at least a child within two minutes between the range of 1months-five years of age.UK treat 1500-2000 people every year of this malaria disease always after international trip .Most are treated with the combination drug: artemether-lumefantrine.
Dr Sutherland added: "It does feel like something is changing, but we're not yet in a crisis.
"It is an early sign and we need to take it quite seriously as it may be snowballing into something with greater impact."It's remarkable there's been four apparent failures of treatment, there's not been any other published account [in the UK]."
