Why are we concerned about the flu, seasonal epidemics of hundreds of thousands of people died each year?
Seasonal flu occurs every year the virus may change each year - but many people have some kind of virus spread, which helps to limit immunity. Some countries also use the seasonal influenza vaccine to reduce disease and death.
However, influenza (H1N1) is a new virus, but most of these people have little or no immunity, so that this virus may lead to more infections than the seasonal flu to see. WHO is working closely with manufacturers to expedite the safe and effective vaccine development, but in a few months ago, is available.
A new influenza (H1N1) seems to be contagious as seasonal flu is spread, especially the young fast (from 10 years old to 45). From very mild symptoms of disease severity ranging from severe disease can lead to death. Most people who contract the virus diseases of experience and the restoration of moderate and anti-viral treatment or medical care. The more serious cases, more than half of the hospital's basic state of health or weakened immune systems.
Most people have experienced mild illness and recovery at home. When someone should seek medical care?
A person should seek medical care, if they are shortness of breath or difficulty breathing, shortness of breath or experience of more than three days if the fever continues. For a young child who is sick, seek medical care for their parents, if the child has fast or breathing difficulties, persistent fever or convulsions (epilepsy).
Support at home to take care - rest, drink plenty of fluids and use of analgesics in pain - is in most cases to restore adequate. (A non-aspirin painkillers, should be used for children because of the risk of Reye syndrome in young people.)
