Swine flu was first isolated from a pig infected in 1930 in the United States. In its development, the disease can transmit to humans primarily affects those in close contact with pigs. Long time no heard from again this virus was subjected to a series of mutations that appeared a new variant of the first attack humans in Mexico in early 2009. The new variant is known as the H1N1 virus which is an abbreviation of the two main viral antigen is hemagglutinin type 1 and neuraminidase type 1.
What are the symptoms of swine flu?

The main symptoms of swine flu are similar to symptoms of influenza in general such as: fever, cough, runny nose, fatigue and headaches. Some patients may experience nausea, vomiting and diarrhea.

If there are bacteria that infect the lungs, engaging the patient may have pneumonia or pneumonia. Some of them may have symptoms of a seizure a seizure. Death usually occurs because of secondary bacterial infection in the lungs so that an appropriate antibiotic is needed to overcome the infection.
How to diagnose swine flu?
Diagnosis of swine flu is being established based on the patient's clinical symptoms and a history of contact with those who have symptoms meraka as above. Further examination of mucus or phlegm from the throat of the patient. This examination is useful to distinguish whether the virus is infecting people with the virus, including type A or B. When we find that the result is of type B virus, it can be ascertained that the patient is not infected with swine flu. But if it turns out the result is a virus of type A then there is the possibility that patients infected with swine flu or H1N1 virus. These samples were then sent to a laboratory equipped to ensure that the swine flu virus antigen swine flu diagnosis can be established with certainty.
How long the swine flu virus spread?
People suffering from swine flu A (H1N1) by the experts will still transmit the disease until the seventh day. If until the seventh day of illness was not improved then it is considered that person can still transmit the disease until the symptoms of flu was completely gone. Especially children under five has the potential transmission of a longer time.
Period of this swine flu is still terggantung again on the type or strain of the H1N1 virus. If the patient is cared for at home then it is advisable not to advance out of the house until the illness is completely cured but is concerned to see a doctor or hospital.
How to treat swine flu?
While it has long found a vaccine to prevent transmission of influenza virus, but a vaccine for swine flu virus (H1N1) to date there has been no. Currently several government laboratories funded by the WHO is developing a research to find a vaccine swine flu virus.
Two anti-viral drug believed to prevent the increased severity of swine flu is zanamivir (Relenza) and oseltamivir (Tamiflu). The use of these drugs should not be arbitrary because it feared would happen virus resistance to both drugs. The drug is also not recommended for symptoms of flu that has appeared more than 48 hours. In the severe circumstances, patients may require more intensive treatment in hospital.
How to prevent transmission of swine flu?
The most effective way to prevent transmission of swine flu virus in principle the same as the way to prevent transmission of influenza virus to another is vaccination. Unfortunately vaccine for swine flu has yet been found.
Another way to prevent transmission of this virus is to minimize contact with the virus such as washing hands frequently, avoid touching your face, especially nose and mouth and avoid close contact with people who are suffering from flu.
Prevention can also be done by those who have been infected by the way: avoid the crowds and always stay at home. Do not work and attend school until the situation improves in advance. Avoid sneezing, coughing and talking too close to another person.
