A research has found that H1N1 infection infected more children and young adults compared to older people. It is different from the normal flu which impacts older people and most of the victims are more than 65 years old.

The report also mentioned that pregnant women in their second and third trimester were at a higher risk of infection. People with obesity and morbid obesity were also found to be at a higher risk of getting the infection.

The infection first reported in Mexico last year, and then spread globally. The virus had spread to almost all the countries of the world by March 2010. It resulted in the death of 17,700 people globally. In US alone, 59 million people till the end of February were infected. Out of these 265,000 were hospitalized and 12,000 people lost their lives.

Even though the rate of infection remained at 11%, the rate of mortality was at 0.5%. The timely action by health care authorities in most of the countries helped people and saved lot of lives across the world.

The infection spread like normal flu and crowded places like schools, hospitals and airports. It also had similar symptoms like coughing, fever and sore throat. Due to this most of the patients mistook it for normal flu. The heartening news is that health experts do not foresee a major upsurge in infection in the coming days.
