Flu, an infectious illness caused by the influenza virus, primarily affects the respiratory system. If a new flu virus emerges to which few people would have immunity, then a pandemic, or global epidemic, could arise - resulting in more severe illness and death than seasonal flu.
Pandemic is a rapidly-spreading epidemic of a disease that affects most countries and regions of the world. The symptoms of pandemic flu are similar to those of the ordinary seasonal flu that occurs each winter, but are usually more severe.
Pandemics occur when a virus emerges that is so different from previously circulating strains that few, if any, people have any immunity to it. This allows it to spread widely and rapidly, affecting hundreds of thousands of people. As it is a new virus it is not possible to produce a vaccine to protect people against it in advance.
You can reduce, but not eliminate, the risk of catching or spreading influenza during a pandemic by taking below precautions :-
- covering your nose and mouth when coughing or sneezing, using a tissue when possible
- disposing of dirty tissues promptly and carefully
- avoiding non-essential travel and large crowds whenever possible
- maintaining good basic hygiene, especially frequently washing your hands
- cleaning hard surfaces frequently
