1. Are swine flu symptoms different from normal human flu?
They are similar. Swine flu is more likely to include diarrhea and vomiting, as well as the respiratory symptoms that come with typical seasonal human flu. Symptoms include:
* Chills
* Cough
* Fatigue
* Fever (greater than 100°F or 37.8°C)
* Headache and body aches
* Sore throat
* Stuffy nose
For information on what swine flu is, please see our what is swine flu? article.
2. How would I know I had swine flu if I had some symptoms?
You wouldn't, neither would your doctor. A respiratory specimen would have to be taken within the first four to five days. The specimen would be sent to a lab, which in the USA would be a CDC lab.
Authorities and experts still do not know why symptoms have been worse in Mexico than in the USA, Canada and other countries.
The important point is to call your doctor if you think you have the flu. Prescription anti-viral drugs such as TamiFlu or Relenza can be called in by your doctor. Unless you are:
* exceptionally ill with flu-like symptoms
* chronically ill
* immune-suppressed
* quite elderly
* or have a very young child, under age 2
It is best not to report to a hospital, as you could risk spreading the disease. Call your doctor and do what he tells you.
3. How long are infected people contagious?
An adult is usually contagious as long as they have symptoms - usually up to seven days following the beginning of the illness. The "shedding stage" of the virus is during the first 4-5 days of illness. Children can be considered contagious longer, up to 10 days. The initial incubation period is 24-48 hours.
4. What medications are there?
There is Tamiflu or Relenza - both have shown to be effective against these recently reported strains of swine flu. There are four anti-viral drugs altogether that are commonly used to treat various strains of flu.
5. Do these medicines prevent me from catching swine flu?
That is not currently advised. Preventative medication might be advisable for very special circumstances where a person had to expose themselves to potentially ill people during an epidemic (which we do not yet have here). Such people might include ER workers. An outbreak in a nursing home, for instance, might lead to protecting all the other residents with a drug like TamiFlu.
As the coverage time is limited, the preventative use of anti-viral medications is not advised for the general public.
Do not confuse OTC (over-the-counter) cold and flu preparations for anti-flu medications that you can only get with a prescription.
6. Do children and adults have the same symptoms?
Symptoms are similar. However, the signs of potentially life-threatening complications are not. The CDC advises those with these symptoms to seek emergency care immediately:
* Being extremely irritable
* Bluish skin color
* Rapid breathing or trouble breathing
* Fever with a skin rash
* Not drinking enough liquids
* Not waking up or interacting
Emergency warning signs in adults are:
* Confusion
* Difficulty breathing or shortness of breath
* Pain or pressure in the chest or abdomen
* Severe or persistent vomiting
* Sudden dizziness
7. Are there any swine flu vaccines?
Not currently. Authorities, such as the CDC in the USA are considering adding the current swine flu strain to next year's vaccine.
8. If I took the swine flu vaccine in the swine flu scare during the 70s, would that protect me now? Will this year's flu shot offer me any additional protection?
Nobody knows whether protection may be full, partial, or not at all. The current swine flu strain also has avian flu components. The avian flu component is not from the deadly bird flu strain.
9. Can I catch it from pigs?
No, you can only catch this strain from other humans. It is a mutated pig virus.
10. Can I catch it from eating pork meat and pork products?
No. Swine flu is not transmitted by the food you consume - it is not a foodborne illness. All pork food products are safe to consume - as long as they are prepared properly. The virus dies at 160 degrees Fahrenheit.
Swine flu is transmitted in the same way normal flu is - through airborne droplets form a sick person's cough or sneeze
11. 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.
12. 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 of this writing (Monday, April 27) We do not know all the factors geographically and demographically that may contribute to the mildness or severity of this flu. But, like seasonal flu, there is the potential for serious outcomes.
13. Why the big concern if the regular flu kills 35,000 people a year, which is why we are all encouraged to get a flu shot?
This is a new flu strain that our bodies have not been exposed to before. The flu strains that the CDC creates a vaccine for each year all have the potential to cause great harm, especially in elderly, pediatric and chronically ill patients. This particular flu strain has struck seemingly healthy, young adults, with some resulting in death in Mexico. It also appears to be quite contagious. We will know more about this strain in the coming days.
14. 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.
15. Is this just another scare that will go away like bird flu?
Bird flu is a theoretical threat and will need a mutation to be able to be transmitted among humans to become a serious threat. The present "swine/avian" virus clearly has already caused a major outbreak in Mexico City and San Luis Potosi, Mexico and has spread to places in the US (California, New York, Texas, Kansas and Ohio). What is not clear yet is whether this virus will result in a so-called pandemic worldwide spread with major outbreaks--or whether it will fizzle out. But, even if it fizzles out, there is logical concern that it might re-emerge next flu season.
16. Should I cancel my vacation to Mexico?
At this writing, the situation is very fluid, changeable. I suggest checking frequently with the CDC Web site for possible Travel Alerts. I probably would not travel to Mexico City for a vacation that could easily be rescheduled, if for no other reason than the city has tried to limit access to crowded or public places where transmission might be facilitated. That does not sound like a very pleasant vacation to me!
Having said that, there are more than 4,000 flights to Mexico from the US and none have been cancelled as of this writing. However, some international airports in Europe and Asia are stepping up precautions and issuing alerts. Again, check the CDC's Travel Alerts page.
17. 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.
18. How long does the germ live on surfaces, like on my desk if someone sneezes in my office?
Influenza virus survives only minutes on inanimate objects or hands, so these are very inefficient ways to spread the illness. Influenza is most easily spread by droplets that come into contact with our mucus membranes such as when someone coughs or sneezes in our faces. If we shake hands with an infected person who has just wiped their nose and then we rather quickly rub our nose or eyes with our own hand, then we could get the flu. So, good hand washing does play a role in diminishing the spread of the disease.
19. 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.
20. What else can I do?
Go to the sources of verifiable information such as WHO (World Health Organization)
Most important, be alert, not panicked.Thank you :)
