British scientists suspect that swine flu virus has mutated in Ukraine. Some doctors say that flu in the country has shown unprecedented symptoms, creating the effect of burnt lungs, the Daily Mail reports.
We have carried out post mortems on two victims and found their lungs are as black as charcoal. They look like they have been burned. It's terrifying, doctor said.
Meanwhile, according to the World Health Organization, no mutations have been registered in virus samples from Ukraine.
