The Ebola outbreak in West Africa has not gone away. By mid-September the virus had killed over 2,600 people in Ghana, Liberia, Sierra Leone and Nigeria.

It is the biggest outbreak in the past 40 years, and the US Center for Disease Control and Prevention predicts that if current trends continue, the number of cases in Liberia and Sierra Leone could exceed 550,000 by January.

So should you be worried?

Well, yes, if you have a family member or friend who is visiting from West Africa and they develop a headache or fever – both are symptoms of Ebola – soon after flying back. However, Public Health England, the government body that monitors infectious diseases, says the risk of an Ebola outbreak occurring in the UK remains ‘very low’.
