Swine Flu / H1N1 / Type A – FAQs
Swine Flu or H1N1 or type A Faqs
1 * What about the transmission of the virus and what the relationship of disease to the pigs?
2 * This disease is no longer being called the Swine flu. Now, according to the WHO, the disease is called the Influenza Type A. Is there any explanation for that?
3 * The flu vaccine is effective against common swine flu?
4 * We know that the age group most affected with this disease is that of young adults. Is there any explanation for that?
5 * How can we prevent of any cases of swine flu(Type A H1N1) ?
6 It is known that the symptoms of this disease are similar to the common flu. But why is it stronger? What causes death?
7* Are there any aggravating facts that further complicate the transmission and treatment of disease, if it really get in your city?
8 * Is there treatment for it?
9.Could we use the Anti Viral drugs for its own account?
The transmission of this new virus occurs among humans. He takes the name of swine flu, because the mutation was from a swine flu virus. The flu is transmitted through secretions of the airways, such as droplets of Spit or saliva and coryza.
One of the first suspected cases were confirmed was a boy of 5 years old in Vera Cruz, Mexico.
The children live next to a farm breeding of pigs.The place has already been examined and be put out of infection because there was no pig infected. Probably the first case occurred in a place like this where pigs and humans live and have contact. The virus outbreak is a combination of that and evolved from mutations of the virus from birds, pigs and humans.The USA cases are endemic (local) and CDC (Center for Disease Control, USA), estimates that 10% of veterinary and 20% of owners of farms with pigs have had influenza “swine” or H1N1, or influenza “A”, as the WHO is naming from Friday pp.In 70’s there was also an outbreak in the U.S., where it recorded a single death, a soldier of the American army.
This disease is no longer being called the Swine flu. Now, according to the WHO, the disease is now called the Influenza Type A.
The explanation for this is purely economic one.The lobbies of pig breeders in the USA and possibly in Mexico have pressure on the WHO and FAO. Resistance to keep the name “Swine” of the flu was causing tensions with the UN agency for food and agriculture ( FAO, in English) and the World Organization for Animal Health, which saw no justification for linking the disease to the pigs .other reason is that consumption of pork is secure.
The flu vaccine is effective against common swine flu?
At 100%, no!
What we do not know is if there is some type of Cross answer is or not able to occur and produce a response to some antigens (parts) of influenza virus type A, or H1N1.The influenza vaccine could provide some protection.
But we need more studies on the cases that are in progress to respond with more certainty this question
While there is indeed an event of death by focusing on young adults, is still unknown as is the pattern of transmission of this new virus. With the occurrence of new cases possibly more will have a better understanding about this fact, assessing whether this is an absolute or relative, as it is a small sample yet
However, the CDC report about the first 8 cases in School “San Francisco” in NY, says with certainty that one of the cases were mild and this fact could, again in the conditional:COULD happened because the protection achieved by the influenza “common” vaccine.
But as it is an unproven hypothesis yet and it is only in the field of hypothesis.However, I would like to insist that it should be taken, not because it confers immunity against swine flu, but to avoid, facing a global epidemic, the risk of being infected by both viruses,at the same time( the common”influenza and this mutant virus), which could lead to an even higher mortality (the similarity with that is seen in the epidemics of Dengue virus by more than one serotype).
Firstly having a healthy and balanced diet involving all classes of nutrients found in fruits, vegetables, sources of carbohydrates such as rice, beans, and sources of animal protein as meat of fish, from cattle, chicken and even the pork, because, as mentioned above the pork meat is secure and offer no risk, when well cooked.
Secondly, if possible avoiding the places where there is already occurring flu type A (H1N1) epidemics as the countries already affected.
For those who are in the affected sites, the recommendation is to avoid urban centers or public agglomerations, such as theaters, cinemas and stadiums.The necessity of using masks for protection, MUST be following the guidance of Health authorities of each Country.
The symptoms of swine flu(H1N1 or Type A) are the same for any viral infection: high fever – greater than or equal to 39 degrees Celsius, myalgia (pain in the body), headache, cough, arthralgia (joint pain) and possibly diarrhea. The differentiation of swine influenza (type A or H1N1), is the epidemiological history, or if the person was in the areas already committed, or had contact with someone who came from areas affected.
The influenza virus can also cause death, and leads in about 0.2-0.3% of cases through the installation of a viral pneumonia This virus of H1N1 Swine Influenza, also can do the same, evolving into a attack the lower airways to reach the lungs and therefore cause a pneumonia. It’s unclear whether to keep the fatality rate of first cases, but the fact is that this was 6-7%, and there comes a HUGE difference between them.A lethality of H1N1 in this beginning of the epidemics is at least 20 times higher!
Are there any aggravating facts that further complicate the transmission and treatment of disease, if it really get in your city?
A:The increase is given by the large population concentration in the large cities of the country, which is inherent in any other big city in the world. Other concerns would be related to nutritional status and education of individuals with regard to hygiene habits, but that are also common to other countries.
.Is there treatment for it?
Yes! Antiviral drugs can be used to treat swine flu or to prevent infection with swine flu viruses. These medications must be prescribed by a health care professional. Influenza antiviral drugs only work against influenza viruses — they will not help treat or prevent symptoms caused by infection from other viruses that can cause symptoms similar to the flu.
There are four influenza antiviral drugs approved for use in the United States (oseltamivir, zanamivir, amantadine and rimantadine). The swine influenza A (H1N1) viruses that have been detected in humans in the United States and Mexico are resistant to amantadine and rimantadine so these drugs will not work against these swine influenza viruses. Laboratory testing on these swine influenza A (H1N1) viruses so far indicate that they are susceptible (sensitive) to oseltamivir and zanamivir.
No, no drug should be used without medical prescription, or on their own. The first thing to do in case of symptoms is to seek a medical service, as another danger is the misuse of medication without medical advice, which may allow the creation of resistant strains of the virus, by inappropriate use of medicines, for inadequate time or no need to use it.
CDC recommends the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with swine influenza viruses.
* Oseltamivir (brand name Tamiflu ®) is approved to both treat and prevent influenza A and B virus infection in people one year of age and older.
* Zanamivir (brand name Relenza ®) is approved to treat influenza A and B virus infection in people 7 years and older and to prevent influenza A and B virus infection in people 5 years and older.
Recommendations for using antiviral drugs for treatment or prevention of swine influenza will change as we learn more about this new virus.
***ONLY Clinicians should consider treating any person with confirmed or suspected swine influenza with an antiviral drug.
