Flu is a common viral infection that can affect anyone. In some cases, flu can be fatal. It is often confused with other illnesses because of the symptoms. Flu is contagious. Everyone will be affected by flu at least once in their lifetime. It is important to know the symptoms of flu so that you can protect yourself or others who may be affected.
Flu is also known as influenza. It is caused by a virus that infects the respiratory tract. The incubation period of flu can last from 1 to 4 days.
If left untreated, symptoms can even last up to 14 days or more. The disease can be spread directly or indirectly. It can be spread from one person to another through airborne droplets from coughing or sneezing. It can also be spread indirectly when a person touches contaminated surfaces.
What are the types of flu?
Even though flu is a common illness, there are many misconceptions about what flu is and isn't. There are different types of flu. Some types of flu are:
Seasonal flu – usually causes illness during a few months of the year. Flu months are called flu season.
October to April is flu season in this country. However, flu season varies depending on where you are in the world. Seasonal flu is caused by three types of influenza viruses, A, B, and C. Influenza A is usually responsible for most seasonal flu cases. Influenza A occurs in humans and animals and is spread from one person to another by infected people. There are different variants of influenza A, which are divided into H subtypes and N subtypes. Influenza B occurs only in humans and is extremely dangerous. However, it can cause epidemics. Influenza C affects only humans but is much milder than A and B. It usually causes mild respiratory illness.
Pandemic Flu – Any type of influenza virus can cause a flu pandemic. During a flu pandemic, people around the world become sick in a large outbreak over a short period of time. Some flu pandemics, such as the 918 flu pandemic, have caused very severe illness and killed millions of people.
H1N1 (Swine Flu) – In the spring of 2009, a new influenza A virus, H1N1 (Swine Flu), was discovered in Mexico. It quickly spread throughout North America, the United States, and around the world. Swine Flu is a hybrid of bird flu, human flu, and pig flu.
H5N1 (Avian Flu) – As the name implies, the H5N1 flu strain, known as bird flu, usually spreads between birds; however, it can also spread from birds to humans. This virus does not spread from person to person. When H5N1 infects humans, it can cause severe illness, multiple organ failure, and high mortality.
