Is there a flu season in warm climates?
The flu doesn’t affect warm climate areas.
This means that anyone in any climate can catch the flu.
Regardless of where you live, it’s possible to catch the flu if you come in contact with someone carrying the disease..
Is the flu considered a viral infection?
Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza is commonly called the flu, but it’s not the same as stomach “flu” viruses that cause diarrhea and vomiting.
Does fresh air kill germs?
Research shows that outdoor air is a natural disinfectant. Fresh air can kill the flu virus and other harmful germs. Equally, sunlight is germicidal and there is now evidence it can kill the flu virus.
Does Lysol kill flu?
Lysol, Clorox, and similar products have long been touted as having the ability to kill 99.9 percent of germs, often on contact. That includes diseases such as flu strains, E. coli and salmonella. And Lysol’s label lists “human coronavirus” as one of the pathogens it can wipe out.
Where does the flu go when it’s not flu season?
With the flu season intensifying, you have to wonder what happens to the viruses that cause the sickness the rest of the year? As it turns out, they migrate—not unlike birds.
Where do most flu viruses originate?
Most influenza viruses that infect humans seem to originate in parts of Asia, where close contact between livestock and people creates a hospitable environment for mutation and transmission of viruses.
Why does flu come in winter?
The virus lives longer indoors in winter, because the air is less humid than outside. While it’s alive and in the air, it’s easy for people to inhale it, or for it to land on the eyes, nose, or mouth. We spend more time indoors and have closer contact with each other, which makes it easier for the virus to spread.
Why does the flu mutate each year?
One way influenza viruses change is called “antigenic drift.” These are small changes (or mutations) in the genes of influenza viruses that can lead to changes in the surface proteins of the virus: HA (hemagglutinin) and NA (neuraminidase).
How did the 1918 flu start?
Some medical historians and epidemiologists have theorized that the 1918 pandemic began in Asia, citing a lethal outbreak of pulmonary disease in China as the forerunner of the pandemic. Others have speculated the virus was spread by Chinese or Vietnamese laborers either crossing the United States or working in France.
At what temperature does flu virus die?
By contrast, influenza viruses, which infect the whole body, grow best at temperatures slightly below body temperature, and at 40° C they will die off after 12-24 hours.
Why is there flu in winter but not summer?
1) During the winter, people spend more time indoors with the windows sealed, so they are more likely to breathe the same air as someone who has the flu and thus contract the virus (3).
Who gets the flu most often?
The same CID study found that children are most likely to get sick from flu and that people 65 and older are least likely to get sick from influenza. Median incidence values (or attack rate) by age group were 9.3% for children 0-17 years, 8.8% for adults 18-64 years, and 3.9% for adults 65 years and older.
What animal did the flu come from?
As researchers have sequenced the influenza viruses found in ducks and other birds, as well as people, swine and other animals, a picture of viral ecology based in nature has come into focus. Birds serve as a reservoir for a vast diversity of influenza viruses to which all the major human pandemics trace their origin.
How does the flu start each year?
Answer: Influenza is a virus that’s spread from person to person. It originates, actually, among birds and other animals such as pigs, and new viral strains of influenza come to this country and to Europe from Southeast Asia.
Can you get the flu anytime of the year?
You can get a cold anytime — spring, summer, or fall, but most likely in winter. Flu season typically runs from November through March, although you can get it in October or as late as May. You can catch the flu at other times of the year.
Do viral infections go away?
But antibiotics only treat infections caused by bacteria. They don’t work on viruses. The good news is that viral infections usually aren’t serious. Most will go away in a few days without medical treatment.
How long do flu germs live on bedding?
Flu germs live 8 to 12 hours on fabric Bedding, especially pillowcases, and your clothes may be important hotspots for germs.
Why is there a flu season and not year round?
Why flu season is in the fall and winter The flu is an airborne infectious disease. So in order to spread, the virus needs to survive long enough in the air to travel from one person to the next. And that’s where the virus’s gel-like coating helps when it’s cold outside.
Can you get the flu any season?
In the United States, flu season occurs in the fall and winter. While influenza viruses circulate year-round, most of the time flu activity peaks between December and February, but activity can last as late as May.
How does flu season end?
In general in the United States, flu season can start anytime in late fall, peak in mid-to-late winter (between January and February), and continue through early spring. 2 On average, flu season lasts about 13 weeks. It will usually end by April, but in some years it can linger into May.
How long will the flu last 2020?
Most people who become sick will recover in a few days to less than two weeks, but some people may become more severely ill. Following flu infection, moderate complications such as secondary ear and sinus infections can occur.
