Second nurse who treated missionaries admitted with suspected Ebola

She was found to be suffering from a fever and is undergoing tests to find out whether she has caught the haemorrhagic virus from the two patients who were air-lifted home in August and September.

Along with a Spanish engineer who has just returned from Nigeria, and a third female nurse who has so far tested negative, the latest patient is the fifth person being held in isolation – although only one case has been confirmed.

Teresa Romero, 44, from Alcorcón (Madrid) was rushed to hospital on Monday and tests for Ebola showed up positive.

Her husband, Javier, is in a separate isolation ward under observation.

At least another 50 people who either treated the missionaries or have been in contact with those currently in hospital are undergoing regular temperature checks.

A helpline has been set up by Madrid health authorities – 91 400 00 01 – and an email address, sanidadinforma@salud.madrid.org.
