Ebola virus a threat

"The risk to UK travellers and people working in [affected countries] of contracting Ebola is very low but we have alerted UK medical practitioners about the situation in West Africa and requested they remain vigilant for unexplained illness in those who have visited the affected area. "It is important to stress that no cases of imported Ebola have ever been reported in the UK and the risk of a traveller going to West Africa and contracting Ebola remains very low since Ebola is transmitted by direct contact with the blood or bodily fluids of an infected person." BBC global health correspondent Tulip Mazumdar said the West African outbreak had been going on for four months. In that time local people had been looking after the sick and carrying out burials, which could actually help to spread the virus, she added. Ebola kills up to 90% of those infected, but patients have a better chance of survival if they receive early treatment. The outbreak - the world's deadliest to date - was first reported in Guinea in February. It then spread to Liberia and Sierra Leone.
