H1N1 Flu Symptoms

About H1N1

People call the H1N1 flu as “swine flu” which is a recent strain of flu virus that is causing illness in humans worldwide. It is also called as “Influenza A” . This strain contains a combination of flu viruses that affect pigs, birds, and humans. Because of the human component, the virus can spread from person to person very easily and rapidly.

Causes of swine flu

Earlier forms of the H1N1 virus were found only in pigs. Over time, the virus changed and can now it is infecting humans all over the world. As H1N1 is a new virus in humans, the immune system cannot fight the virus very well. As a result, it has spread rapidly around the world. The largest number of H1N1 flu cases have occurred in people aged from 5 to 24. Very few cases, and no deaths, have been reported in people who are older than age 64.

How H1N1 is Transmitted?

H1N1 flu symptoms spread the same way that other flu viruses do. They may spread through the air when a person who has the virus sneezes, coughs, or speaks. People also can catch the virus after touching an object that someone with the virus has sneezed or coughed on.

As with other flu viruses, people who have the virus can be contagious a day or so before their symptoms start, so they can pass it on before they even know they’re sick.

We might have heard that flu epidemics often start in schools. If health authorities in your state become concerned that a flu outbreak is possible, they may close schools as a precaution to help slowdown the spread of the infection. 

Signs and Symptoms

Some of the common h1n1 flu symptoms are similar to other flu. A person with swine flu may have:
- Fever
- Cough
- Sore throat
- Runny nose or stuffy nose
- Body aches

Prevention Techniques

- Drink lots of liquids, especially if you’re throwing up or have diarrhea.
- Stay home from school as long as your doctor recommends.
- Limit contact with other people to help prevent the spread of illness.
- Cough or sneeze into tissues instead of your hands.
- If you have asthma, make sure you follow your asthma management plan to keep it under control.


The Centers for Disease Control and Prevention (CDC) recommends that teens take the following precautions against swine flu:

- Wash your hands often with soap and water or use hand sanitizer — particularly before eating.
- Should avoid touching your eyes and mouth.
- Avoid being around people who are sick and be sure to wash your hands if you touch anything someone who seems sick might have touched.
