Funny enough, a lot of us in healthcare have somewhat rolled our eyes at the widespread panic caused by the outbreak of the Swine Flu. H1N1 is actually the name of a subtype of influenzavirus A, and the most common cause of influenza in humans (including seasonal). The Swine Flu belongs to this group. I do not discount the possibilities of potential mutations from the current strain, but that has always been and always will be a potential threat with any viral strain. The flu happens every year, and at this point this is simply another form of it. People have been treated at home, and the mortality rates have been about the norm for the typical influenza. Mortality doesn't actually occur from the influenza itself usually, but from secondary causes such as pneumonia and exacerbation of cardiopulmonary and other underlying conditions. That said, the elderly are the most vulnerable for severe complications. Around 36,000 people die from the flu on average each year in the United States, and over 225,000 are actually hospitalized. I know that part very well, I was in the hospital two years ago with a severe case (that year they badly predicted and the vaccine only covered about 35% or so of the strains out there). There was a notable rise in cases for that year, but myself as well as everyone else I knew while miserable recovered quickly. As for historical outbreaks such as 1918, the main reason so many young, otherwise healthy adults died was due to a particularly virulent strain that caused and killed largely from what is called a cytokine storm-a potentially fatal overreaction of the person's own immune system that essentially attacks the victim's body, which is why the strong immune systems of younger people were a target. At this time there is no indications that there have been any similar occurrences from this strain, and the main concern many of us have are a possible higher caseload of cases for flu this year than normal.
That said, all of the healthcare professionals I know as well as myself are doing common sense precautions. Always cover your mouth when you cough. Take advantage of any flu vaccinations available-I will be lining up for mine in the next couple of weeks at work. Exercise frequent hand washing, and a lot of us do carry personal hand sanitizers. Avoid touching your mouth, nose, or eyes, as this is a common entrance for germs on the hands picked up off of various surfaces into the body. If you're sick, STAY HOME. Exposing others causes the spread, so that only makes sense. The symptoms of influenza include fever. cough, sore throat, body aches, headache, fatigue, chills, nausea/vomiting, and diarrhea. If you do become ill, seek treatment accordingly.
