Influenza, commonly known as the flu, is a contagious respiratory illness caused by viruses. It can cause mild to severe illness, and in some cases, can lead to death. The flu is spread through tiny droplets of saliva and mucus that are released when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby.
Swine flu, also known as Influenza A (H1N1), is a type of influenza virus that is common in pigs. It is an infectious respiratory disease caused by a virus, and it can be passed from person to person. In 2009, a new strain of H1N1 virus emerged, causing a global pandemic. This strain is sometimes referred to as “swine flu”.
The symptoms of swine flu are similar to those of other types of flu, including fever, chills, body aches, sore throat, headache, and fatigue. In some cases, it can also cause vomiting and diarrhea. It is important to note that swine flu is generally mild, and most people who get it recover without needing medical treatment. However, it can be serious in some cases, and can lead to complications such as pneumonia and respiratory failure. It is recommended that people who have underlying medical conditions or weakened immune systems seek medical attention if they develop symptoms of swine flu. Vaccination is also recommended for people who are at higher risk of developing complications.
