Understanding the different aspects of a flu outbreak
Flu or influenza is a contagious respiratory illness caused by the influenza virus. It can result in mild to severe illness and health complications. A severe flu infection can result in hospitalization and can even prove to be fatal, especially in young children, older people aged above 65, and people with underlying health conditions. There are two main types of flu viruses: Type A and Type B virus. The illness can be periodical and result in seasonal flu epidemics each year. The cold, flu, and its symptoms such as cough is caused due to the type of the viruses mentioned above. Influenza may not always be considered by most people as a serious illness, its symptoms comprising a runny nose, headaches, cough, and muscle pain can be confused with those of a heavy cold. Yet reports suggest that seasonal influenza can claim up to 650,000 lives every year. That is why influenza vaccinations are important because they protect people, especially those in at-risk categories, such as young children, the elderly, pregnant women, and people with vulnerable immune systems or underlying health conditions. What most of us call “the flu” is essentially seasonal influenza because it comes around in the coldest season twice a year, once in the Northern hemisphere’s winter, and once in the Southern hemisphere’s winter in temperate zones of the world.
