That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms. During this time, those persons may still spread the virus to others.
Can you be a carrier of the common cold?
As for viruses that cause colds, people can, in fact, transmit these viruses with mild or minimal symptoms themselves. In this case, they're considered asymptomatic carriers. They usually don't have the virus in their system for a prolonged period of time, though.
Flu viruses capable of being transferred to hands and causing an infection can survive on hard surfaces for 24 hours. Infectious flu viruses can survive on tissues for only 15 minutes. Like cold viruses, infectious flu viruses survive for much shorter periods on the hands.
The typical incubation period for influenza is 1—4 days (average: 2 days). Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.
Unfortunately, no. Experts say it is possible to catch the flu twice in one season. But a smaller portion of people (around 10 to 15 percent) are getting the H1N1 strain or the influenza B virus, according to data from the Centers for Disease Control and Prevention.
The flu is a viral infection caused by the influenza virus, a respiratory virus. The common cold is also a viral infection caused by the adenovirus or coronavirus and there are many, many subsets with a lot of variability. That's why it's said there's no cure for the common cold [and] there's no real vaccine.
Unfortunately, no. Experts say it is possible to catch the flu twice in one season. The CDC recommends the flu vaccine for everyone ages 6 months and older. This flu season is turning out to be one of the worse since the 2009 "swine flu" epidemic, CDC officials said last week.
A. You can't get exactly the same one, as your body will have developed antibodies to it. But “cold and flu viruses mutate, so there are subtly different forms of the virus,” says Caroline Rudnick, an assistant professor of community and family medicine at St. Louis University.
Even If You Don't Have Symptoms, You May Still Have The Flu. Fever, muscle aches, nausea — these are what we usually associate with having the flu. In fact, their study found that roughly three-quarters of people with seasonal or pandemic flu show either no symptoms or mild ones that aren't usually linked to flu.
An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but who display no signs nor symptoms. Although unaffected by the pathogen themselves, carriers can transmit it to others.
How long does it take to develop symptoms of influenza after being exposed? The incubation period of influenza is usually two days but can range from one to four days. Typical influenza disease is characterized by abrupt onset of fever, aching muscles, sore throat, and non- productive cough.
MYTH: You can catch the flu from the vaccine. The vaccine is made from an inactivated virus that can't transmit infection. So people who get sick after receiving a flu vaccination were going to get sick anyway. But people assume that because they got sick after getting the vaccine, the shot caused their illness.
A hereditary carrier (or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. The chance of two carriers having a child with the disease is 25%.
Usually, you'll need nothing more than bed rest and plenty of fluids to treat the flu. But in some cases, your doctor may prescribe an antiviral medication, such as oseltamivir (Tamiflu) or zanamivir (Relenza).
About a week. You're contagious from 1 day before you have any symptoms. You stay that way for 5 to 7 days after you start feeling sick. Kids may be able to spread the virus for even longer, until all of their symptoms fade.
Symptoms of influenza usually appear 1-4 days after exposure. How long can a person spread influenza? Persons are most contagious during the 24 hours before symptoms appear and may be contagious for up to 5 -7 days after getting sick.
Every year, flu kills 12,000 to 56,000 people and sends as many as 700,000 to the hospital. CDC estimates flu deaths by looking at how many more people than usual died of flu and pneumonia, but even those calculations miss people who may have died from flu complications, such as a heart attack set off by a bout of flu.
Disease carrier. Disease carrier could refer to: Asymptomatic carrier, a person or organism infected with an infectious disease agent, but displays no symptoms. Genetic carrier, a person or organism that has inherited a genetic trait or mutation, but displays no symptoms.
Influenza — commonly known as the flu — is a respiratory infection caused by flu viruses. There are three main types of influenza: A, B, and C. Types A and B are similar, but influenza B can only pass from human to human. Learn other symptoms that could indicate a type B influenza infection.
There also are flu antiviral drugs that can be used to treat and prevent flu.
- Avoid close contact. Avoid close contact with people who are sick.
- Stay home when you are sick.
- Cover your mouth and nose.
- Clean your hands.
- Avoid touching your eyes, nose or mouth.
- Practice other good health habits.
Other reactions following the flu shot are usually mild and can include a low grade fever and aches. If these reactions occur, they usually begin soon after the shot and last 1-2 days. The most common reactions people have to flu vaccine are considerably less severe than the symptoms caused by actual flu illness.
