What is Swine Flu?Swine flu is a form of influenza type A. -Influenza type A is found in people and animals as well as in birds. Type B is found only in humans and usually has much less severe symptoms. Type C is milder still and closer to a mild cold. Whether it's type A or B, it's more commonly referred to as the seasonal flu, and we've all suffered through it, (how to prevent flu) and likely on more than one occasion in our lives, during the flu season. -But in the spring of 2009 a new strain of type A was discovered in Mexico that has been since referred to as the Swine Flu. It is more accurately known as H1N1, the H1N1 Virus and novel H1N1. In June of 2009 the World Health Organization (WHO) declared the H1N1 pandemic (worldwide) to alert level phase 6, the first time this has occurred since the Hong Kong flu of 1968. (see symptoms) -In October of 2009, President Barack Obama declared this H1N1 virus strain a national emergency, and by the end of November -WHO announced, "207 countries and overseas territories/communities have reported laboratory confirmed cases of pandemic influenza H1N1 2009, including at least 8,768 deaths." These viral infections have no cure. It's the same as when you get a common cold or flu. Over-the-counter products you may take are designed to treat the symptoms of the cold or flu and in most cases the symptoms will generally become less severe as the virus runs its course, and you feel better. What's in a name? -When the flu strain pandemic was first announced, many people believed that only those who worked with pigs or who ate pork could become infected with the virus, neither is true. Many infected even denied having this strain of flu, to avoid what they perceived as a negative association. This only made the spread of the virus much more prevalent. -H1N1 2009 is not the same strain as found in pigs. There has been much debate about what this strain should be called, but right or wrong, it is now commonly known as "Swine Flu" -This new version does have two genes from viruses usually found in European pigs, but also has genes in common with bird flu and other human strains of the flu virus. Because of this, it is also known as "quadruple re-assortment H1N1" How does H1N1 differ from seasonal flu? This particular strain has never been seen anywhere in the world before, and because of this no one has any previous immunity to it. -When vaccines are prepared, each vaccination contains a portion of the virus specific to that particular strain. It has been discovered that the H1N1 virus is very similar to an influenza virus outbreak that existed in the early 1900s. Because of the long passage of time however, few people living today have any immunity at all to protect them from it. This is why there is such concern. -Without this previous immunity, the possibility exists that a lot more people, other than the usual high-risk groups (children under 5, pregnant women and adults over 65) could possibly contract this strain and become sick. -In fact, this particular flu virus seems to affect more people in other age groups than any other influenza strain seen before. What are the Swine Flu Symptoms? Symptoms are similar to those of the seasonal flu virus. There is no way to tell it from the seasonal flu bug unless your doctor takes a sample swab from your throat or nasal passages. A testing laboratory can then analyze the culture taken. -Like the common cold or flu, symptoms often include:
Unlike a seasonal flu or cold, the H1N1 virus includes diarrhea and vomiting in over 25% of the cases seen, sometimes severe. -Also, unlike seasonal flu, 25% of the deaths and over 50% of the hospitalizations are among young children and adults under 25. Are Some Swine Flu Symptoms Worse Than Others? -Yes, even more so when seen in children and young adults, and in some cases may even be life threatening. -Especially worrisome symptoms may include:
*For adults, these symptoms may also include dizziness, confusion and chest pain. Symptoms often improve only to return even more severe. -If any of these symptoms appear -See your doctor right away! What's the Best Treatment for H1N1? In treating it after the fact, (preferably within 48 hours of onset) they also work well, along with traditional treatments for any specific symptoms. -It is also very important to stay hydrated and to drink plenty of fluids as you fight any viral infection. Should I get vaccinated for the Swine flu? -Is the vaccine safe? This may also be of help against this new strain, as the body will be less susceptible to this component of the virus. At the very least, your symptoms may be less severe and with a shorter duration than someone who did not receive the seasonal flu vaccine. -There is also a vaccination on the market now that is being distributed to help reduce the incidence of H1N1, the supply is limited but is ever increasing. Who should receive the Swine flu vaccine first? -People caring for infants younger than 6 months old -Those in medical or healthcare service -Toddlers 6 months old and up through adults 24 years old. -Adults 25 - 64 who may be a higher risk for respiratory complications resulting from existing health conditions or other health problems. -Pregnant women and children under the age of 5 are especially vulnerable and should definitely get the swine flu vaccine. -Unlike the seasonal flu, Swine flu is more prevalent among people under 24 years of age. -It is also much less likely to occur in people over the age of 65. In most cases, the swine flu will run it's course much like the seasonal flu. -It's still a very good idea to get vaccinated; this may prevent the spread to those who may be at a higher risk of complications from the virus.
