Swine flu and swine flu treatment at home
Swine flu, also known as swine influenza, is a contagious respiratory disease that affects pigs. Like humans, pigs can get the flu. Swine flu can be transmitted from pig to pigs through direct contact, indirect contact (eg a pig that has been in contact with a virus-contaminated surface) or tiny droplets in the air.
Strains of the swine flu virus usually infect only pigs, but they sometimes infect humans, leading to human swine flu.
Swine flu is caused by a virus. The subtype, or strain, the best known is influenza A type H1N1 subtype that has also infected humans. It is important to note, however, that the virus that causes swine influenza A (H1N1) is different from the human influenza A (H1N1) virus. The letters H and N of the name given to the subtype of the virus correspond to the proteins on the surface of the virus; they serve to distinguish different subtypes. Other virus subtypes are found in pigs, including H1N2, H3N1 and H3N2.
The genes of influenza viruses are constantly changing. This process is called a mutation. When a swine influenza virus is detected among humans, it is said that the virus has crossed the species barrier. This means that the virus has mutated so that it can cause infection among humans. Since humans do not have the natural protection or immunity against the virus, they are more likely to contract it.
Swine flu, human and avian influenza viruses (which affect the bird) can infect pigs. When a pig is infected with influenza viruses from different species, these viruses can exchange genes, and a new virus containing the mixed genetic material of various viruses of different species is assembled.
Humans do not usually contract swine flu. However, there have been periodic infections among humans; most cases occurred among people who had direct exposure to pigs (eg, hog farm workers). Pigs have also been infected with strains of the human influenza virus.
Person-to-person transmission of the human swine flu virus has been proven, but it is unclear what promotes the spread of the virus in the human population. It is believed to be spread in the same way as seasonal flu. The virus that is transmitted by a cough or sneeze is transmitted from person to person by entering the body through the eyes, nose or mouth. The virus can also remain on solid surfaces such as doorknobs, ATM keys and counters. A person who touches one of these surfaces with his hands and subsequently touches his eyes, mouth or nose may contract the virus.
Swine flu can not be infected by eating primed pork at 71 ° C (160 ° F) internal cooking temperature.
Symptoms and Complications
The swine flu virus triggers symptoms that are very similar to those of seasonal flu. People infected may have the following symptoms:
nasal congestion, nasal discharge;
fatigue, lack of energy;
nausea, vomiting, diarrhea;
loss of appetite
a dry cough.
Laboratory diagnostic tests can be requested by the doctor to help identify the flu virus or he can diagnose your symptoms. You should consult your doctor if you have recently traveled to a part of the world where there has been an outbreak of human swine flu, if you have been in contact with infected swine (eg at an agricultural fair , a petting zoo, a pig farm), and if you are at high risk for more serious infection (eg if you are pregnant or old, or if you have asthma). Call before going to your doctor’s office so that staff can take steps to protect them and those in the waiting room.
Treatment and Prevention
There are vaccines that provide immunization for swine, but for the moment there are no vaccines that protect humans against swine flu.
Interested individuals can purchase medications that can help them prevent and treat swine flu. These are the drugs called antivirals. Two classes of antivirals are available: M2 protein inhibitors (eg, amantadine *) and neuraminidase inhibitors (eg, oseltamivir, zanamivir).
Most people who have been infected with human swine in the past have recovered completely without the need for medical care or antiviral drugs.
For those affected, improve your condition and prevent the spread of the virus by taking the following precautions:
stay home if you have contracted the virus. Do not go to work or school;
keep at least 1 meter apart between other people;
rest and drink plenty of fluids;
Always Cover your mouth with a tissue . Then throw it in the trash. If you do not have tissue paper handy, cough or sneeze by covering your face with your elbow or hands away from people nearby. Wash your hands thoroughly afterwards;
Wash your hands regularly with soap and water. Be sure to wash your hands with soap for at least 15 seconds. Use an alcohol-based hand sanitizer if you do not have access to soap or water.
There are ways to protect yourself from the swine flu virus. People who may be associated with infected swine or travel to areas where a swine flu outbreak has occurred need to take extra precautions to reduce the risk of exposure to the swine flu virus. Here are some tips to prevent the flu:
avoid close contact with infected people who have symptoms of swine flu (eg, fever, coughing)
Wash hands thoroughly with soap and water. To perform a good cleansing, you should wash your hands with soap and scrub for at least 15 seconds. Use an alcohol-based disinfectant if you can not wash your hands;
get immunized against the flu every year (flu vaccine). This may not protect you from swine flu, but it can prevent the contraction of some strains of human flu. This can prevent infection with both the avian influenza virus and the human influenza virus;
adopt healthy habits such as getting enough sleep, eating a nutritious diet and staying physically active.
