How do symptoms of swine flu differ from other types of flu?
None, really, although this flu might include gastrointestinal symptoms (diarrhea and vomiting), as well as the usual respiratory symptoms. The basic symptoms for swine flu are similar to the seasonal flu we are vaccinated for each year, which may include, fever, sore throat, cough, stuffy nose, chills, headache and body aches, fatigue.
Is there medication for this?
Yes, Tamiflu or Relenza have shown to be effective against these recently reported strains of swine flu. Altogether, there are four anti-viral drugs that we commonly use to treat various strains of flu.
Is there a vaccine?
Not yet, but the CDC has this current strain of virus and will consider whether to add it to next year's flu vaccine as time goes on.
Can I catch it from pigs?
No. This strain is one that is communicable through human-to-human contact. It is a mutated form of a swine virus.
Can I catch it from eating pork?
Absolutely not! Swine flu is not transmitted by food. It is not a so-called foodborne illness. Bacon, ham and other pork products are safe to eat, assuming they are prepared properly. An internal temperature of 160 degrees for cooked meat will kill any bacteria or virus.
Swine flu is transmitted by airborne droplets from an infected person's sneeze or cough; or from germs on hands, or germ-laden surfaces. Eating pork will not give you swine flu any more than eating chicken will give you bird flu.
How does it cross from a pig to a human?
The swine virus mutates so that it can infect humans and be spread by humans.
Can it kill me?
Deaths have been reported from the Mexico City outbreak. So far the cases in the US have been mild and there have been no deaths as yet. But, like seasonal flu, there is the potential for serious outcomes.
How is it different from avian (bird) flu?
Avian flu so far has had difficulty infecting humans unless they are exposed intensely to birds, because the virus has not mutated in a way that makes it transmissible by humans to other humans. This virus has origins genetically from both pigs and birds, and the big difference from the avian flu is that this swine virus can be transmitted readily from human to human.
What if I'm on a plane? Should I wear a mask?
Not necessary. The air on a plane is filtered. Transmission might occur if someone sitting close to you coughs or sneezes on you. The newer designs of aircraft airflow keep the air in a top-down flow, not forced air from front to back. However, if you do have a respiratory illness, it might be best not to travel.
Other than hand washing and covering my mouth if I sneeze or cough, what can I do to take care of myself and others?
If you are ill, stay home. Control your sneezes and coughs. If you cough into your hand, remember the virus could be live on your hand at least for a few minutes, so wash your hands before touching anyone else. If you get symptoms suggesting the flu, call your doctor, who can call in a prescription for medication to treat the flu. Resist going to the doctor's office or a hospital ER for influenza symptoms unless you are seriously ill. You do not want to spread the disease to others.
"There is a huge difference between preparedness and paranoia. Although we're dealing with a new strain of flu, a set of universally applicable preventive measures exist that can be employed right away by everyone to help stop the spread of this disease," said Dr. Robert Emery, occupational health expert at the UT School of Public Health at Houston.
WHO Guidelines
What can I do to protect myself from catching influenza A(H1N1)?
The main route of transmission of the new influenza A(H1N1) virus seems to be similar to seasonal influenza, via droplets that are expelled by speaking, sneezing or coughing. You can prevent getting infected by avoiding close contact with people who show influenza-like symptoms (trying to maintain a distance of about 1 metre if possible) and taking the following measures:
* avoid touching your mouth and nose
* clean hands thoroughly with soap and water, or cleanse them with an alcohol-based hand rub on a regular basis (especially if touching the mouth and nose, or surfaces that are potentially contaminated)
* avoid close contact with people who might be ill;
* reduce the time spent in crowded settings if possible;
* improve airflow in your living space by opening windows;
* practise good health habits including adequate sleep, eating nutritious food, and keeping physically active.
What about using a mask? What does WHO recommend?
If you are not sick you do not have to wear a mask.
If you are caring for a sick person, you can wear a mask when you are in close contact with the ill person and dispose of it immediately after contact, and
cleanse your hands thoroughly afterwards.
If you are sick and must travel or be around others, cover your mouth and nose.
Using a mask correctly in all situations is essential. Incorrect use actually increases the chance of spreading infection.
How do I know if I have influenza A(H1N1)?
You will not be able to tell the difference between seasonal flu and influenza A(H1N1) without medical help. Typical symptoms to watch for are similar to seasonal viruses and include fever, cough, headache, body aches, sore throat and runny nose. Only your medical practitioner and local health authority can confirm a case of influenza A(H1N1).
What should I do if I think I have the illness?
If you feel unwell, have high fever, cough or sore throat:
* stay at home and keep away from work, school or crowds
* rest and take plenty of fluids
* cover your nose and mouth when coughing and sneezing and, if using tissues, make sure you dispose of them carefully. Clean your hands immediately after with soap and water or cleanse them with an alcohol-based hand rub
* if you do not have a tissue close by when you cough or sneeze, cover your mouth as much as possible with the crook of your elbow
* use a mask to help you contain the spread of droplets when you are around others, but be sure to do so correctly
* inform family and friends about your illness and try to avoid contact with other people
* If possible, contact a health professional before traveling to a health facility to discuss whether a medical examination is necessary
Should I take an antiviral now just in case I catch the new virus?
No. You should only take an antiviral, such as oseltamivir or zanamivir, if your health care provider advises you to do so. Individuals should not buy medicines to prevent or fight this new influenza without a prescription, and they should exercise caution in buying antivirals over the Internet.
What about breastfeeding? Should I stop if I am ill?
No, not unless your health care provider advises it. Studies on other influenza infections show that breastfeeding is most likely protective for babies - it passes on helpful maternal immunities and lowers the risk of respiratory disease. Breastfeeding provides the best overall nutrition for babies and increases their defense factors to fight illness.
When should someone seek medical care?
A person should seek medical care if they experience shortness of breath or difficulty breathing, or if a fever continues more than three days. For parents with a young child who is ill, seek medical care if a child has fast or labored breathing, continuing fever or convulsions (seizures).
Supportive care at home - resting, drinking plenty of fluids and using a pain reliever for aches - is adequate for recovery in most cases. (A non-aspirin pain reliever should be used by children and young adults because of the risk of Reye's syndrome.)
Should I go to work if I have the flu but am feeling OK?
No. Whether you have influenza A(H1N1) or a seasonal influenza, you should stay home and away from work through the duration of your symptoms. This is a precaution that can protect your work colleagues and others.
Can I travel?
If you are feeling unwell or have symptoms of influenza, you should not travel. If you have any doubts about your health, you should check with your health care provider.
WHO Travel Guidelines
Is it safe to travel?
Yes. WHO is not recommending travel restrictions related to the outbreak of the influenza A(H1N1) virus. Today, global travel is commonplace and large numbers of people move around the world for business and leisure. Limiting travel and imposing travel restrictions would have very little effect on stopping the virus from spreading, but would be highly disruptive to the global community.
Influenza A(H1N1) has already been confirmed in many parts of the world. The global response now focuses on minimizing the impact of the virus through the rapid identification of cases, and providing patients with appropriate medical care, rather than on stopping its spread internationally.
Although identifying signs and symptoms of influenza in travellers can help track the path of the outbreak, it will not reduce the spread of influenza, as the virus can be transmitted from person to person before the onset of symptoms.
Scientific research based on mathematical modelling shows that restricting travel would be of limited or no benefit in stopping the spread of disease. Historical records of previous influenza pandemics, as well as experience with SARS, validate this.
Does WHO recommend screenings at country entry and exit points to detect if ill people are travelling?
No. We do not believe entry and exit screenings would work to reduce the spread of this disease. However country-level measures to respond to a public health risk are the decision of national authorities, under the International Health Regulations 2005.
Countries that adopt measures that significantly interfere with international traffic (e.g. delaying an airplane passenger for more than 24 hours, or refusing country entry or departure to a traveller) must provide WHO with the public health reasoning and evidence for their actions. WHO will follow up with all of its Member countries on such matters.
Travellers should always be treated with dignity and respect for their human rights.
How can I protect myself from influenza A(H1N1) when I am travelling?
People who are ill should delay travel plans. Returning travellers who become ill should contact their health care provider.
Travellers can protect themselves and others by following simple prevention practices that apply while travelling and in daily life. |
