In India, Swine Flu is spreading like wild fire. So, it is high time for you to take some precautionary measures and learn the DO’s and DONT’s. This article tries to enlighten you on some facts about swine influenza A (H1N1) virus.   What is new influenza A (H1N1)?   Swine flu (also referred to as novel H1N1 virus) is a new virus that hasn't spread before among humans. The virus was first detected in people in the United States in April 2009. This virus is spreading from person-to-person worldwide, probably in much the same way that regular seasonal influenza viruses spread.   Why is 2009 H1N1 virus called “swine flu”?   This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs (swine) in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and bird (avian) genes and human genes. Scientists call this a "quadruple reassortant" virus.   Why is this strain of flu causing so much concern?   It's a brand new mutation that's never been seen before. That's why it's not just hitting people in the highest risk groups — those over 65 and younger than two.   How does swine flu spread?   Human infection with swine flu viruses are most likely to occur when people are in close proximity to infected pigs, such as in pig barns and livestock exhibits at fairs.   Human-to-human transmission of swine flu can also occur. This is thought to occur in the same way as seasonal flu occurs in people, which is mainly person-to-person transmission through coughing or sneezing of people infected with the flu virus.   How long can an infected person spread this virus to others?   People infected with seasonal and 2009 H1N1 flu shed virus and may be able to infect others from 1 day before getting sick to 5 to 7 days after. This can be longer in some people, especially children and people with weakened immune systems and in people infected with the new H1N1 virus.   What are the symptoms of swine flu in humans?   The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza and include fever, lethargy, lack of appetite and coughing. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea.   How does swine flu kill?   Swine flu — just like any other flu — is a respiratory infection. It exploits a weakened immune system to attack major organs — especially your lungs. When it gets into your lungs, it can lead to pneumonia, which can kill you. The flu can also cause secondary infections in your body — any of which can lead to failure of vital organs and death.   What is the best technique for washing my hands to avoid getting the flu?   Washing your hands often will help protect you from germs. Wash with soap and water or clean with alcohol-based hand cleaner. CDC recommends that when you wash your hands - with soap and warm water - that you wash for 15 to 20 seconds.   Should I wear a face mask or respirator?   There's a difference between a face mask and a respirator. A face mask does not seal tightly to the face. Face masks include masks labeled as surgical, dental, medical procedure, isolation, or laser masks. Respirators are N95 or higher filtering face pieces that fit snugly on the face. Respirators, when correctly adjusted, filter out virus particles - but it's hard to breathe through them for extended periods.   People who have flu-like symptoms should carry disposable tissues to cover their coughs and sneezes. When going out in public, or when sharing common spaces around the home with family members, they should put on a face mask - if one is available and tolerable.   People not at risk of severe flu illness can best protect themselves from swine flu with frequent handwashing and by staying at least six feet away from people with flu symptoms. But if swine flu is circulating in the community, a face mask or respirator may be protective in crowded public places.   Can people catch swine flu from eating pork?   No. Swine flu viruses are not transmitted by food. You cannot get swine flu from eating pork or pork products. You won't get swine flu from handling uncooked pork either. You can get sick from putting uncooked or undercooked pork in your mouth, but you won't get swine flu.   Can I catch swine flu by eating imported fruits?   It's also … [Read more...]
