What is swine flu?猪流感是什么
It is a contagious respiratory disease of pigs caused by type A influenza viruses. Pigs are hit by regular outbreaks. There are many different types of swine flu and the current cases involve the H1N1 strain of type A influenza virus.
How do humans catch it?
While people do not normally catch it, humans can contract the virus, usually if they have been in close contact with pigs. It is also possible for the constantly changing infection to spread from person to person, which has happened in the latest outbreak. Experts believe it spreads in the same way as seasonal flu - through coughing and sneezing.
What are the symptoms?猪流感的症状是什么？
The symptoms of swine influenza in people are similar to the symptoms of regular human seasonal influenza infection and include fever, fatigue, lack of appetite, coughing and sore throat. Some people with swine flu have also reported vomiting and diarrhoea.
What is the difference between swine flu, avian flu and the flu commonly seen in the UK during the winter?猪流感和禽流感的区别，以及与冬天的流感区别？
Influenza viruses are commonly circulating in the human and animal environment, with different strains causing illness in humans, bird and pigs. Seasonal influenza is caused by viruses that are adapted to spread in humans. Humans have some natural immunity to the strains that are in common circulation, and this immunity can be boosted by immunisation with a vaccine. Avian influenza is caused by influenza viruses adapted for infection in birds. Similarly, swine influenza is caused by influenza viruses adapted for infection in pigs. These illnesses all cause the same respiratory symptoms in sufferers and can be passed between one another.
How dangerous is it?猪流感有多危险？
More than 80 people have died and thousands made ill, in Mexico in particular, although cases have also been reported in the US and New Zealand. However, testing has shown that the antiviral drugs oseltamavir (Tamiflu) and zanamivir (Relenza) appear to be effective against the human swine influenza H1N1 strain,
Why should we be worried about it?我们为什么要担心猪流感？
The World Health Organisation warned the outbreak had "pandemic potential" and countries were advised to step up surveillance and preparation in case the infection spreads rapidly. Flu viruses have the ability to change and mutate, making it difficult for drugs manufacturers to ensure effective vaccines are available. The new version of the H1N1 virus is a mix of different animal and human versions of the disease. Mixing can lead to the development of changed viruses to which humans have little immunity.
What is a pandemic?什么叫流行病？
If the flu spreads over a wide geographic area and affects a large proportion of the population it goes beyond an epidemic and becomes a pandemic. According to the Health Protection Agency, an influenza pandemic is defined as a new or novel influenza virus that spreads easily between humans. When new influenza viruses are introduced into the environment, humans do not have any natural immunity to protect against them. Therefore, there is a risk that that new influenza viruses could develop into a pandemic if the virus passes easily from human-to-human.
Will it spread to the UK?猪流感会传播到英国么？
It is too early to say whether the cases reported so far will lead to a larger outbreak, the HPA said. No cases have been reported in the UK although experts are monitoring the situation closely. Anyone who has recently returned from affected countries should consult a doctor if they notice flu-like symptoms.
What is being done in the UK to prevent the infection?英国目前怎样预防？
The HPA said it is working with the UK government to review the current incident and any threat it poses to UK public health. It advised people to follow general infection control practices and good hygiene to reduce transmission of all viruses. This includes covering their nose and mouth when coughing or sneezing, disposing of dirty tissues promptly and carefully, washing hands frequently with soap and water and cleaning surfaces which are regularly touched.

Swine flu has yet to escalate into a global pandemic, but here's what to do if it does
5 Ways to Protect Yourself (and Others) from Swine Flu
Experts say that the steps you should take to shield yourself from swine flu are not much different than those you might take to ward off seasonal flu。
1. Don't touch your face
Above all, keep your hands away from your eyes, mouth and nose, all of which serve as pathways for the virus to enter your respiratory tract, says Allison Aiello, an epidemiologist at the University of Michigan School of Public Health in Ann Arbor。
2. Wash your hands
If you must touch your face, scrub your hands, getting under the fingernails and inside all crevices, for 20 to 30 seconds with hot soap and water beforehand, Aiello says. "In addition to dislodging dirt that may contain virus particles, soaps contain surfactants [the primary components of detergents] which can damage the lipid [fat] protecting virus particles," she explains. Soap should therefore be effective against all flu viruses。
3. Use a hand sanitizer
No sink nearby? Then use an alcohol-based hand sanitizer, Aiello advises. About a quarter-size spot, rubbed all over the hands until the sanitizer evaporates (usually 10 to 15 seconds)， should do it. Alcohol can inactivate viruses by destroying the structure of their proteins, she notes。
4. Cover your nose and mouth
When someone sneezes or coughs, liquid droplets packing flu viruses can travel as far as three feet (one meter) through the air and descend on your nose or mouth, so it's best to maintain at least an arm's-length distance when talking to someone who shows signs of infection, says Louise Dembry, director of epidemiology at Yale–New Haven Hospital in Connecticut. And to protect others, cover your mouth and nose with a tissue when you cough or sneeze, and clean your hands afterward, she says, noting that viruses can remain infectious for hours, if not longer, when they linger on the skin or other surfaces such as keyboards and subway poles。
5. Consider buying a mask in case you need it in the future
From press photos, it seems that Mexico's entire population has donned surgical masks, but the verdict is still out on how effective they are in stemming the spread of flu, according to Aiello. Some research suggests that masks—either the surgical variety or respirators called N95's specially designed to filter out water droplets containing viruses—reduce the risk of contracting the flu or other respiratory pathogens by as much as 80 percent, but research by Aiello's team suggests that masks do little unless used in conjunction with diligent hand washing。
According to the U.S. Centers for Disease Control and Prevention, there is "extremely limited" data on the effectiveness of face masks and respirators for blocking flu spread in communities. The agency suggests, however, that people consider using them when it's impossible to avoid "crowded settings or close contact with others" in areas where swine flu transmission has been confirmed: face masks for crowded places and respirators for situations that involve close contact with people who have respiratory infections (caring for a sick family member, for example)。

The Swine Flu virus detected in Mexico is the H1N1 Swine Flu virus strain that has killed more than 152 people in Mexico , a Mexico government advised , citing results from tests done in report. The Swiss government advised its citizens to avoid non-essential travel to Mexico on Tuesday.A man admitted that all of the suspected patients, having recently been to Mexico, were already quarantined and received necessary medication, but a series of tests are needed to confirm whether they are really infected with swine flu virus. We can overcome it.We has been urging citizens with symptoms of the flu -- a sharp increase in body temperature, headaches, muscular pains and breathing problems -- to visit their nearest medical center as soon as possible. 如何预防猪流感？ 例如写：1、我们已经在城市公共场所发放口罩.The city has been giving out face masks on public transport. 2、我们已经要求有流感症状包括: 发烧/ 头疼/ 肌肉疼(浑身疼)以及呼吸问题的市民尽早去附近医疗中心治疗.We has been urging citizens with symptoms of the flu -- a sharp increase in body temperature, headaches, muscular pains and breathing problems -- to visit their nearest medical center as soon as possible.
