What are the different stages of the flu?
A bout of the flu typically follows this pattern: Days 1–3: Sudden appearance of fever, headache, muscle pain and weakness, dry cough, sore throat and sometimes a stuffy nose.
Day 4: Fever and muscle aches decrease.
Hoarse, dry or sore throat, cough and possible mild chest discomfort become more noticeable..
How effective is this years flu shot 2020?
CDC’s influenza vaccination coverage reports show that overall flu vaccination coverage (among people 6 months and older) during 2019-2020 increased from the previous season to nearly 52%.
How long will flu test show positive?
Samples should be collected within the first 3-4 days of illness. Rapid influenza diagnostic tests (RIDTs) provide results within approximately 15 minutes; viral culture provides results in 3-10 days.
How is flu B treated?
Several over-the-counter medications can help ease the symptoms of influenza. These are available from drug stores. In severe cases, a doctor may prescribe a course of antiviral drugs. Oseltamivir (Tamiflu) and zanamivir (Relenza) are drugs that doctors may use to treat type A or type B influenza.
Can you get both flu A and flu B at the same time?
Scientists Report Rare Occurrence of Humans Harboring Two Strains of Flu at the Same Time | Infection Control Today.
What flu is going around 2020?
“Nationally, flu activity has been elevated … and continues to increase; this represents somewhat of an early start to the U.S. flu season,” said Scott Pauley, a press officer for CDC. “Flu activity is currently being caused mostly by influenza B/Victoria viruses, followed by H1N1 viruses and H3N2 viruses.
Whats the difference between Flu A and Flu B?
Influenza B almost exclusively infects humans and is less common than influenza A. Flu type B also mutates about two to three times more slowly than influenza A. Because humans are the natural host of influenza B, pandemics generally do not occur with influenza B viruses.
Is diarrhea a symptom of the flu?
Early flu symptoms can extend below the head, throat, and chest. Some strains of the virus can cause diarrhea, nausea, stomach pain, or vomiting. Dehydration is a dangerous complication of diarrhea and vomiting.
What is Type D flu?
Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people. Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N).
Can you get two different flu strains?
Experts say it is possible to catch the flu twice in one season. That’s because there are multiple strains of flu viruses circulating at any one time, said Dr. William Schaffner, an infectious-disease specialist at Vanderbilt University Medical Center in Nashville.
Can you test positive for flu A and B?
Background. Rapid influenza diagnostic tests (RIDTs) are immunoassays that can identify the presence of influenza A and B viral nucleoprotein antigens in respiratory specimens, and display the result in a qualitative way (positive vs. negative) (1). In the United States, a number of RIDTs are commercially available.
How accurate is flu swab?
The diagnostic accuracy of influenza swabs is often overestimated by clinicians. The CDC notes that rapid influenza testing has a sensitivity ranging from approximately 50% to 70% — meaning that in up to half of influenza cases, the flu swab results will still be negative.
How do you know if you have influenza B?
The symptoms may be a little milder for the B strain, but overall, they don’t differ much: a cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue, and sometimes fever.
How long does the 2020 flu last?
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.
How long is someone with flu contagious?
People with flu are most contagious in the first three to four days after their illness begins. 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.
How contagious is type A flu?
Most people with flu are contagious for about 1 day before they show symptoms. Older children and adults with flu appear to be most contagious during the initial 3-4 days of their illness but many remain contagious for about 7 days. Infants and people with weakened immune systems can be contagious for even longer.
Which is worse flu A or B?
Influenza type A and type B are similar, but type A is overall more prevalent, sometimes more severe, and can cause flu epidemics and pandemics.
Why does flu season end?
Why flu season is in the fall and winter “The virus survives better in cool, dry temperatures,” Simanek said. And that’s thanks to a protective gel-like coating that surrounds the flu virus while it’s in the air. The flu is an airborne infectious disease.
