Bird Flu Alarm

Signs and symptoms

Like other types of flu, bird flu symptoms often include:

- a high temperature (fever)

- aching muscles

- headache

- respiratory symptoms, such as a cough or runny nose

Diarrhoea, vomiting, abdominal (tummy) pain, chest pain, and bleeding from the nose and gums have also been reported as early symptoms in some people.

These symptoms can come on suddenly. The time from infection to the start of symptoms (incubation period) is usually three to five days, although in some cases it can be up to seven days.

Within days of symptoms appearing, potentially fatal complications such aspneumonia, acute respiratory distress syndrome and multiple organ failure may develop. Prompt treatment with antiviral medication may help prevent complications and reduce the risk of death.
