History

The H1N1 influenza, or its more common name, swine flu, was first discovered in North America in April 2009. This flu is a respiratory illness and is a virus combined of human, swine and avian strains.

Spread

The H1N1 flu was initially declared an epidemic when cases were reported in Mexico, the United States. When the virus spread outside the continent to China, Europe and the United Kingdom, the World Health Organization declared a pandemic.

Symptoms

The symptoms for the H1N1 flu are typically the same symptoms you would have if you contracted a normal flu. according to WebMD.com. More benign symptoms are a runny nose, fever, chills, sore throat and cough. More debilitating symptoms include fatigue, sluggishness, head and body aches and chills. Those who have contracted the illness have also come down with diarrhea and vomiting. Nausea has also been reported.

Signs

Those with the flu will usually have at least two of the symptoms. However, not all people who have the symptoms are sick with the H1N1 virus. Make a note as to whether or not you are likely to have contracted the illness. If you have traveled recently, been around large groups of children or adults, received a notice from work or school or are in an area where there are high concentrations of those infected, it is more likely that the aforementioned symptoms indicate that you have the virus.

Children

The H1N1 flu has the potential to affect children differently. On rare occasions, children can have neurological side effects from the virus that can often be fatal. Symptoms include seizures and changes in mental state such as changes in awareness, emotional changes, erratic thought patterns, etc.

Underlying Conditions

Those with asthma and other respiratory illnesses are particularly susceptible to the flu and should take precautions. Others who have severe illnesses should also remain in bed or away from large groups to reduce the chances of contracting the virus.
