What is a pandemic flu?

A pandemic flu is a global outbreak of a new influenza virus that causes widespread illness and death. Pandemic influenza is different from seasonal influenza, which occurs every year. Pandemic influenza occurs irregularly and can cause much more severe illness and death.

The World Health Organization (WHO) defines a pandemic as "an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people."

The most recent pandemic flu was the H1N1 pandemic of 2009, which caused an estimated 151,700 to 575,400 deaths worldwide.

Pandemic flu can be caused by any new influenza virus that is able to infect humans and spread easily from person to person. These viruses can come from animals, such as birds or pigs, or they can be created in a laboratory.

Pandemic flu viruses are often more contagious than seasonal influenza viruses, and they can cause more severe illness and death. People who are at high risk of complications from pandemic flu include:

* Pregnant women

* Young children

* People with chronic medical conditions, such as heart disease, lung disease, or diabetes

* People over 65 years old

There are several things that can be done to prevent and control pandemic flu, including:

* Getting vaccinated against seasonal influenza every year

* Washing your hands frequently with soap and water

* Avoiding close contact with people who are sick

* Staying home from work or school if you are sick

* Covering your mouth and nose with a tissue when you cough or sneeze

In the event of a pandemic flu outbreak, it is important to stay informed about the latest news and recommendations from public health officials.
