Swine flu is a respiratory disease, caused by a strain of the influenza type A virus known as H1N1.
H1N1 is the same strain which causes seasonal outbreaks of flu in humans on a regular basis.
But this latest version of H1N1 is different: it contains genetic material that is typically found in strains of the virus that affect humans, birds and swine.
Although the strain may have originated in pigs, it is now a wholly human disease.
It can be spread from person to person by coughing and sneezing.
Symptoms of swine flu in humans appear to be similar to those produced by standard, seasonal flu.
A fever – which is a temperature of 38ºC (100.4ºF) – is the key symptom, combined with other complaints which may include a cough, sore throat, body aches, chills and aching limbs. Some people with the virus have also reported nausea and diarrhoea.
As with normal flu, the severity of symptoms will depend on treatment and the individual. Many people have only suffered mildly and have begun to recover within a week.
People are most infectious soon after they develop symptoms, but they cease to be a risk once those symptoms have disappeared. The incubation period may be as little as two days.
Apparently healthy people are dying from the virus. Does that means it is getting worse?
Experts say this does not change anything, and that if anything it is surprising that it has taken this long in the UK for someone without underlying health problems to die.Read more..
