Early symptoms include the following:
- High fever (above 37.7ºC – the main indication)
- Joint and muscle pain. Weakness
- Abdominal (stomach) pain
- Lack of appetite
- Unexplained haemorrhage (bleeding)
After the fourth or fifth day of the disease, the following may also appear:
- Kidney and liver failure
- Maculopapular rash
- Massive internal or external haemorrhaging
Incubation period: symptoms of the disease may appear anywhere between 2 and 21 days after exposure to the virus, although they usually appear between 2 and 12 days after exposure.
These symptoms can only be indicative of the disease caused by the Ebola virus if there is a record of the sufferer having been in contact with a symptomatic infected patient, or if the person is in one of the affected countries or has been within the last 21 days.
Recovery of the patient depends on their own immune response. As from the second week of infection, patients either go on to develop multiple organ failure resulting in death or progress towards recovery. The Ebola virus does not lead to chronic infections.
If these symptoms and conditions appear, patients in Spain should call 112 to report their symptoms and detail the circumstances that may have caused contraction of the disease (travel to an affected county, contact with an affected person, etc.).
