What is swine flu? Like people, pigs can also get influenza (flu), but swine flu viruses are not the same as human flu viruses. Swine flu doesn't often infect people, and the rare human cases that have occurred in the past, have mainly affected people who had direct contact with pigs. But the current ‘swine flu’ outbreak is different. Cause : swine flu is caused by a new swine flu virus that has changed in ways that allow it to spread from person to person and it's happening among people who haven't had any contact with pigs. That makes it a human flu virus. To distinguish it from flu viruses that infect mainly pigs and from the seasonal influenza A H1N1 viruses that have been in circulation for many years, the CDC calls the virus "novel influenza A (H1N1) virus" and the World Health Organization calls it as "pandemic (H1N1) 2009". The CDC calls swine flu illness "H1N1 flu" and the World Health Organization calls it "pandemic influenza A (H1N1)".

Symptoms of swine flu :Regular flu symptoms and include fever, cough, sore throat, runny nose, body aches, headache, chills, and fatigue are the main symptoms of swine flu . Many people with swine flu have had diarrhea and vomiting too. Nearly everyone with flu has at least two of these symptoms. But these symptoms can also be caused by many other conditions. Health care professionals may offer a rapid flu test, although a negative result doesn't necessarily mean,one does not have the flu. Neurologic symptoms : Like seasonal flu, pandemic swine flu can cause neurologic symptoms in children. These events are rare, but, as cases associated with seasonal flu have shown, they can be very severe and often fatal. Laboratory Tests : Only laboratory tests can definitively show whether it is swine flu. State health departments can do these tests. But given the large volume of samples coming in to state labs, these tests are being reserved for patients with severe flu symptoms. Currently, doctors are reserving antiviral drugs for people with or at risk of severe influenza. |

Frequently Asked Questions:
1. Who is at highest risk from H1N1 swine flu?
Most U.S. cases of H1N1 swine flu have been in older children and young adults. It's not clear why, and it's not clear whether this will change.
But certain groups are at particularly high risk of severe disease or bad outcomes if they get the flu:
People in these groups should seek medical care as soon as they get flu symptoms.
A striking number of adults who developed severe swine flu complications have been morbidly obese. However, obesity itself does not seem to be the issue. The vast majority of extremely obese people suffer respiratory problems and/or diabetes, which seem to be the underlying reason for their severe flu complications.
2. If I think I have swine flu, what should I do? When should I see my doctor?
if you have flu symptoms, stay home, and when you cough or sneeze, cover your mouth and nose with a tissue. Afterward, throw the tissue in the trash and wash your hands. That will help prevent your flu from spreading
If you have only mild flu symptoms, you do not need medical attention unless your illness gets worse. But if you are in one of the groups at high risk of severe disease, contact your doctor at the first sign of flu-like illness. In such cases, the CDC recommends that people call or email their doctor before rushing to an emergency room.
But there are emergency warning signs.
Children should be given urgent medical attention if they:
Adults should seek urgent medical attention if they have:
Keep in mind that your doctor will not be able to determine whether you have swine flu, but he or she may take a sample from you and send it to a state health department lab for testing to see if it's swine flu. If your doctor suspects swine flu, he or she would be able to write you a prescription for Tamiflu or Relenza.
These antiviral medications aren't a question of life or death for the vast majority of people. Most U.S. swine flu patients have made a full recovery without antiviral drugs.
The new swine flu virus apparently spreads just like regular flu. You could pick up germs directly from droplets from the cough or sneeze of an infected person, or by touching an object they recently touched, and then touching your eyes, mouth, or nose, delivering their germs for your own infection. That's why you should make washing your hands a habit, even when you're not ill. Infected people can start spreading flu germs up to a day before symptoms start, and for up to seven days after getting sick, according to the CDC.
The swine flu virus can become airborne if you cough or sneeze without covering your nose and mouth, sending germs into the air. Ferret studies suggest that swine flu spreads less easily by small, airborne droplets than does seasonal flu. But it does spread by this route, and it may begin to spread even more readily as the new virus fully adapts to humans.
The new swine flu virus is a human virus spread by people and not by pigs. The only way to get the new swine flu is from another person.
Pandemic swine flu virus is sensitive to the antiviral drugs Tamiflu and Relenza. The CDC recommends those drugs to prevent or treat swine flu; the drugs are most effective when taken within 48 hours of the start of flu symptoms. But not everyone needs those drugs. Most people who have come down with swine flu have recovered without treatment. The federal government has replenished state stockpiles of Tamiflu and Relenza in preparation for the fall flu season. Health officials have asked people not to hoard Tamiflu or Relenza.
Tamiflu or Relenza may also be used to prevent swine flu. The CDC recommends this "can be considered" for people at high risk of severe flu illness who come into close contact with someone who has the flu.
Vaccines are being made in large quantities. Clinical tests began in August 2009. Depending on how long federal officials wait for the results of these tests, millions of doses of swine flu vaccine could be ready as soon as September 2009, with more vaccine becoming available each month thereafter.
Although the decision to begin mass vaccinations has not yet been made, federal and state governments are looking at a mid-October launch. By then, 45 million vaccine doses should be available -- fewer than originally predicted, but enough to cover the highest risk groups. Each week after that, another 20 million doses a week will be delivered to states. The U.S. has purchased a total of 195 million doses.
If swine flu vaccine is in short supply -- nationally or in local areas -- pregnant women and people caring for or living with infants will go to the front of the line. So would health care workers and first responders who have direct contact with patients, children 6 months to 4 years old, and kids 4 to 19 years old with medical conditions that put them at risk of severe flu disease. There are about 42 million Americans in these groups.
If the vaccine supply seems sufficient to meet initial demand, priority will extend to all young people aged six months to 24 years, to people 25 to 64 with underlying medical conditions that put them at risk of severe flu disease, and a larger group of health care workers and emergency medical technicians.
Once there's enough vaccine for these urgent groups, swine flu vaccine will be offered to healthy people 24 and older.
Many questions remain. It's not yet clear whether people will need one or two shots, given three weeks apart, or whether an immune-boosting substance called adjuvant will have to be used.
Spurred by the safety concerns that sank vaccination efforts during the 1976 swine flu scare, federal officials are increasing efforts to track the safety of a pandemic flu vaccine. In addition to beefing up the CDC's vaccine adverse-event surveillance system, health care organizations and the U.S. military will be helping track vaccine safety.
5. I had a flu vaccine this season. Am I protected against swine flu?
No.This season's flu vaccine does not protect against the new swine flu virus.
Whether or not there's a swine flu vaccine this winter, there will be a new seasonal flu vaccine in the fall. This year, it will be more important than ever to get a flu shot. It may not protect against swine flu but it will keep you and others from getting the seasonal flu viruses that kill some 36,000 Americans each year.
6. How can I prevent swine flu infection?
The CDC recommends taking these steps:
Short answer: Maybe. Face masks and respirators may very well offer extra protection, but should not be your first line of defense against either pandemic or seasonal flu.
Every day, newspapers carry pictures of people wearing face masks to prevent swine flu transmission. But very little is known about whether face masks actually protect against the flu.
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-rated filtering face pieces that fit snugly to the face. Respirators filter out virus particles when correctly adjusted which is not as simple as it sounds. But it's hard to breathe through them for extended periods, and they cannot be worn by children or by people with facial hair.
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 hand washing and by staying at least 6 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.
People at increased risk of severe flu illness pregnant women, for example should add a face mask to these tried-and-true precautions when providing assistance to a person with flu-like illness. And anyone else who cannot avoid close contact with someone who has swine flu (if you must hold a sick infant, for example) may try using a face mask or respirator.
Flu bugs can survive for hours on surfaces. One study showed that flu viruses can live for up to 48 hours on hard, nonporous surfaces such as stainless steel and for up to 12 hours on cloth and tissues. The virus seems to survive for only minutes on your hands -- but that's plenty of time for you to transfer it to your mouth, nose, or eyes.
Yes. You can't get swine flu by eating pork, bacon, or other foods that come from pigs.
Keep informed of what's going on in your community. Your state and local health departments may have important information if swine flu develops in your area. For instance, parents might want to consider what they would do if their child's school temporarily closed because of flu. Don't panic, but a little planning wouldn't hurt.
Here's the advice from the U.S. government's pandemicflu.gov web site:

11. How severe is swine flu?
The severity of cases in the current swine flu outbreak has varied widely, from mild cases to fatalities. Most U.S. cases have been mild, but there have been a number of deaths and hundreds of hospitalizations mostly in young people aged 5 to 24.
Like seasonal flu, children who get swine flu can have serious neurological complications such as seizures and Reye's syndrome. But as with seasonal flu, these complications fortunately are rare.
Studies of the swine flu virus show that it is more infectious to lung cells than are seasonal flu viruses. But studies also suggest that the swine flu virus is less well adapted to humans and may be harder to inhale deep into the lungs.
Flu viruses change all the time, and the way the pandemic swine flu virus evolved suggests that it is particularly liable to swap gene segments with other flu viruses. But so far the swine flu virus hasn't changed much. That's good news, as the vast majority of swine flu cases have been mild. And it's also good news for the swine flu vaccine, which is based on swine flu strains isolated early in the pandemic.
It's impossible to know whether the virus will become more deadly. Scientists are watching closely to see which way the new swine flu virus is heading -- but health experts warn that flu viruses are notoriously hard to predict.
But there's a lot of planning you can do. CDC officials predict that just about every U.S. community will have H1N1 swine flu cases. It's possible some schools in your community may temporarily close, or even that major gatherings may be canceled. So make contingency plans just in case you are affected. For more information on preparedness planning, see the U.S. government's pandemicflu.gov web site.
That's not clear yet. Researchers around the world are investigating the differences between the cases in Mexico and those elsewhere. The data so far suggests that many more people in Mexico had mild swine flu infections than had originally been appreciated. So the disease now seems to have been no more severe in Mexico than elsewhere.
Yes. There was a swine flu outbreak at Fort Dix, N.J., in 1976 among military recruits. It lasted about a month and then went away as mysteriously as it appeared. As many as 240 people were infected; one died.
The swine flu that spread at Fort Dix was the H1N1 strain. That's the same flu strain that caused the disastrous flu pandemic of 1918-1919, resulting in tens of millions of deaths worldwide.
Concern that a new H1N1 pandemic might return in winter 1976 led to a crash program to create a vaccine and vaccinate all Americans against swine flu. That vaccine program ran into all kinds of problems not the least of which was public perception that the vaccine caused excessive rates of dangerous reactions. That may not have been the case. But after more than 40 million people were vaccinated, the effort was abandoned.
As it turned out, there was no swine flu epidemic.
Even though it's an H1N1 type A flu bug, the new swine flu is a different virus than the ones that emerged in 1918 and in 1976 and from the seasonal type A H1N1 virus that has been circulating for many years.
There have been two flu pandemics since 1918 one that began in 1957, and another that began in 1968.
Probably not.The new swine flu virus is different from the 1976 virus. And it's not clear whether a vaccine given more than 30 years ago would still be effective.
That's no longer possible to answer, because so many people have become infected that most nations can no longer test everyone suspected of having H1N1 swine flu. The CDC counts hospitalizations and deaths. But instead of misleading case counts, the CDC offers a map showing where flu is widespread and charts showing whether unusual numbers of people are showing up in doctors' offices with flu-like symptoms and whether there are unusually high numbers of deaths from pneumonia and influenza.
The U.S. government has declared swine flu to be a public health emergency. The World Health Organization considers it a global emergency.
It remains to be seen how severe swine flu will be in the U.S. and elsewhere, but countries worldwide are monitoring the situation closely and preparing for worst-case scenarios.
The World Health Organization has declared swine flu to be a pandemic. That means that all nations can expect to see swine flu infections and should prepare for them but does not mean the virus has become more severe.
The H1N1 swine flu outbreak came at the end of the U.S. flu season. The virus spread across the nation and around the globe in the spring and summer, seasons when flu usually ebbs to nearly undetectable levels in the Northern Hemisphere.
In the Southern Hemisphere, most nations have seen large numbers of H1N1 swine flu cases. Fortunately, there's no sign that the pandemic flu bug has become more deadly, more resistant to new flu drugs, or less likely to be stopped by the H1N1 swine flu vaccine now in production.
Nobody knows how bad the swine flu will be during the Northern Hemisphere flu season. But the CDC is warning Americans to prepare for a bad flu season this fall. It's better to over-prepare and look a little silly if nothing happens than to be unprepared for an emergency.
17. Are Designer masks being produced by some companies?
How would it affect the use of them as precautionry measures?
Many companies thought that wearing old designed plain masks, would be boring. So to add it’s userfriendiness towards protection from the swine flu, they added a designer flavour to masks. Yes, it will affect positively Find some of the interesting Designer masks to choose from,
