As an expert in the field of epidemiology and infectious diseases, I have spent a significant amount of time studying the various causes and transmission patterns of illnesses, including swine flu. Swine flu, also known as H1N1 influenza, is a respiratory disease that primarily affects pigs but can also infect humans. It is caused by a specific type of influenza virus known as influenza A virus, which has the ability to mutate and adapt, leading to different strains that can cross species barriers.
The main cause of swine flu is the influenza A (H1N1) virus. This virus is a zoonotic pathogen, meaning it can be transmitted between animals and humans. The H1N1 virus is a subtype of the influenza A virus, characterized by the presence of two surface glycoproteins: hemagglutinin (H) and neuraminidase (N). The "H" in H1N1 refers to the hemagglutinin protein, which is of type 1, and the "N" refers to the neuraminidase protein, which is also of type 1.
Transmission of swine flu to humans typically occurs through direct contact with infected pigs or contaminated environments. However, under certain circumstances, the virus can be transmitted from human to human through respiratory droplets produced when an infected person coughs or sneezes. This mode of transmission is similar to that of seasonal flu viruses.
It is important to note that **swine flu is not transmitted through consuming pork**. Properly cooked pork products are safe to eat, and the heat used in cooking kills the virus. The concern arises when the virus is present in the environment or on surfaces that come into contact with humans.
One of the reasons swine flu is considered very contagious is due to the ease with which the influenza virus can spread. The virus can survive on various surfaces for a short period, and individuals can become infected by touching a contaminated surface and then touching their mouth or nose. Additionally, the virus can spread through airborne transmission in enclosed spaces.
Prevention measures for swine flu include practicing good hygiene, such as frequent handwashing with soap and water, especially after contact with pigs or visiting places with pigs, like farms or livestock exhibits. Covering one's mouth and nose when coughing or sneezing, and avoiding close contact with sick individuals are also recommended.
Vaccination is another crucial preventive measure. The seasonal flu vaccine often includes protection against the H1N1 virus. While the vaccine's composition is reviewed and updated annually to match circulating strains of the virus, it can provide a significant level of protection against swine flu.
In conclusion, the main cause of swine flu is the influenza A (H1N1) virus, which can be transmitted between pigs and humans, and under certain conditions, from person to person. It is a highly contagious disease, but proper hygiene practices, avoiding contact with infected animals or humans, and vaccination can significantly reduce the risk of infection.

Swine flu is caused by a strain of influenza virus that usually only infects pigs. Unlike typhus, which can be transmitted by lice or ticks, transmission usually occurs from person to person, not animal to person. You can't catch swine flu from eating properly cooked pork products. Swine flu is very contagious.May 30, 2017
