Victim: Mr Sawyer, with one of his children, died from Ebola in West Africa

mirror |  Doctors fear Ebola victim Patrick Sawyer may have sparked a worldwide spread of the killer disease after being allowed on two flights while infected.

And tonight a desperate race was on to find dozens of passengers who flew on the same jets as the 40-year-old American.

British doctors and border officials have been warned to be on the lookout for people in the UK showing signs of the disease.

Mr Sawyer was allowed to board an ASKY Airlines flight in Liberia, where Ebola is rife, despite vomiting and suffering from ­diarrhoea. His sister was recently killed by the virus.

He had a stopover in Ghana then changed planes in Togo and flew to the international travel hub of Lagos in Nigeria. The dad-of-three died five days after arriving in the city.

Lancaster University virologist Derek ­Gatherer said passengers, crew and airport ground staff who came into contact with Mr Sawyer could be in “pretty serious danger”. Ebola is fatal in 90% of cases.

Doctors have identified 59 people who were near him and have tested 20. But they are struggling to find the others, who could have flown to anywhere in the world from Lagos.

Update: Doctors are reportedly investigating the first possible case of the Ebola virus in Hong Kong. A man has also been tested at a hospital in Birmingham and has been given the all clear. Get latest news in our live coverage and on our dedicated page.

There were today questions over how Liberian government worker Mr Sawyer was let on flights while clearly showing symptoms of Ebola – which has killed 672 people in Liberia, Guinea and Sierra Leone since it broke out in February.
