And it's likely that some of those unfortunates will get the flu again before the year is up. The main reason is that there are many different varieties of the flu virus. Influenza viruses come in four main types: A, B, C, and D. And for each type, there are numerous unique subtypes and strains. For the last 28 years, the most common viruses that infected people each flu season were type A flu viruses. However, this year, the CDC has found more cases of type B infections — something that hasn't happened since If you've been infected with type B you're still susceptible to contracting type A and vice versa because you've only built up an immunity to that specific type B, or A, virus that made you sick the first time.
In fact, if you're unlucky and get the flu a second time in the same season or year, it's unlikely you've caught the same strain. However, there are probably too many influenza viruses total to count. But there's a silver lining: the more strains you're exposed to, the stronger your immune system will likely be against the same or similar strains in the future. That's why flu vaccines are the best weapon against not only avoiding the flu once but multiple times because they contain multiple different substrains of influenza types A and B.
That means your symptoms will be less severe than they'd be otherwise. As for getting the flu during spring or summer months compared to fall and winter — when the flu is in full swing in the northern hemisphere — your chances are low , but it's not impossible.
Yep, really. Influenza A and influenza B cause the seasonal epidemics we've come to expect in the fall and winter, and there are different strains of each. When you get sick from one particular strain of flu virus, your body develops an immune response that will protect you from getting re-infected with the very same bug. If you got the flu from this particular virus in, say, December, you could encounter another form of the bug—like H1N1 or influenza B—come February and get sick again.
At least getting the flu once doesn't give you a higher risk of going in for a second round. A downloadable flyer containing this information also is available. Fever can be one of the symptoms of a flu-like illness for many people. A fever is an oral temperature of at least degrees Fahrenheit Signs of a fever include chills, a flushed appearance, feeling very warm, or sweating.
Fever-reducing medicines typically contain acetaminophen such as Tylenol or ibuprofen such as Motrin. These medicines can both help bring fever down and relieve pain. To help avoid spreading the flu, if you have a fever, stay at home for at least 24 hours after you no longer have a fever or signs of a fever.
However, if you're taking fever-reducing medicines, you cannot tell if your fever is truly gone. Therefore, when you start to feel better, increase the interval between doses of fever-reducing medicines and continue to monitor your temperature to make sure your fever does not return.
Joe Bresee describes the main symptoms of flu, including H1N1 flu, and when it is serious enough to seek medical help. In children:. Joe Bresee explains the nature of antiviral drugs and how they are used. The intent of these parties is for a person to become infected with what for many people has been a mild disease, in the hope of having natural immunity H1N1 flu virus that might circulate later and cause more severe disease.
CDC does not recommend "swine flu parties" as a way to protect against H1N1 flu in the future. While the disease seen in the current H1N1 flu outbreak has been mild for many people, it has been severe and even fatal for others. There is no way to predict with certainty what the outcome will be for an individual or, equally important, for others to whom the intentionally infected person may spread the virus. Vaccination against H1N1 with a H1N1 vaccine is the best way to protect against this virus.
CDC recommends that people with H1N1 flu avoid contact with others as much as possible. Studies have shown that influenza virus can survive on environmental surfaces and can infect a person for 2 to 8 hours after being deposited on the surface.
In addition, several chemical germicides, including chlorine, hydrogen peroxide, detergents soap , iodophors iodine-based antiseptics , and alcohols are effective against human influenza viruses if used in proper concentration for a sufficient length of time. If soap and water are not available and alcohol-based products are not allowed, other hand sanitizers that do not contain alcohol may be useful.
Germs can be spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air. Germs can be spread when a person touches respiratory droplets from another person on a surface like a desk, for example, and then touches their own eyes, mouth or nose before washing their hands.
To prevent the spread of influenza virus, it is recommended that tissues and other disposable items used by an infected person be thrown in the trash. Additionally, persons should wash their hands with soap and water after touching used tissues and similar waste. To prevent the spread of influenza virus it is important to keep surfaces especially bedside tables, surfaces in the bathroom, kitchen counters and toys for children clean by wiping them down with a household disinfectant according to directions on the product label.
Linens, eating utensils, and dishes belonging to those who are sick do not need to be cleaned separately, but importantly these items should not be shared without washing thoroughly first. Linens such as bed sheets and towels should be washed by using household laundry soap and tumbled dry on a hot setting. Individuals should avoid "hugging" laundry prior to washing it to prevent contaminating themselves. Individuals should wash their hands with soap and water or alcohol-based hand rub immediately after handling dirty laundry.
You cannot get infected with HIN1 from eating pork or pork products. Eating properly handled and cooked pork products is safe. Tap water that has been treated by conventional disinfection processes does not likely pose a risk for transmission of influenza viruses.
Current drinking water treatment regulations provide a high degree of protection from viruses. No research has been completed on the susceptibility of H1N1 flu virus to conventional drinking water treatment processes. However, recent studies have demonstrated that free chlorine levels typically used in drinking water treatment are adequate to inactivate highly pathogenic H5N1 avian influenza.
It is likely that other influenza viruses such as H1N1 would also be similarly inactivated by chlorination. To date, there have been no documented human cases of influenza caused by exposure to influenza-contaminated drinking water. Influenza viruses infect the human upper respiratory tract.
There has never been a documented case of influenza virus infection associated with water exposure. Recreational water that has been treated at CDC recommended disinfectant levels does not likely pose a risk for transmission of influenza viruses. No research has been completed on the susceptibility of H1N1 influenza virus to chlorine and other disinfectants used in swimming pools, spas, water parks, interactive fountains, and other treated recreational venues.
