QUESTION 1

There are four types of influenza viruses: A, B, C, and D. The two that cause epidemics in humans are ___ and ___.

Please Select an Answer.
Correct
Wrong

Only A and B cause seasonal flu epidemics in humans

Influenza A and B are the two types that cause seasonal epidemics each year. Influenza A can also be broken down into different strains (you’ve probably heard the term “H1N1” before, for example). Influenza C can cause a mild respiratory illness but does not typically cause an epidemic, and influenza D affects cattle but has not infected humans (yet).

QUESTION 2

The typical flu season lasts from ___ to ___.

Please Select an Answer.
Correct
Wrong

It can be a long trudge to the finish line

Each flu season varies, but most years the flu season begins in October or November and lasts as late as May. The CDC defines the flu season as a time when hospital visits for suspected influenza, positive flu test results, and deaths caused by the flu rise and remain elevated for a few consecutive weeks. While the full flu season is long, the peak time is typically between December and February.

QUESTION 3

Experts recommend the flu shot for everyone starting at the age of ___.

Please Select an Answer.
Correct
Wrong

Flu vaccines can start at six months

Children under the age of five have the highest risk of flu-related complications, such as pneumonia, dehydration, sinus and ear infections, or—in rare cases—death. The CDC recommends all children six months and older get the flu shot each year to prevent unnecessary serious illnesses.

QUESTION 4

Symptoms of the flu usually begin ___ day(s) after you’re exposed to the virus.

Please Select an Answer.
Correct
Wrong

Symptoms may not appear ASAP

After you contract the flu from someone else, the virus may take its time before showing symptoms. That’s important to know, because you may be able to infect other people with the flu before you even realize you have it yourself. That’s why practicing good hygiene during the flu season is critical, whether you have flu symptoms or not.

QUESTION 5

The flu shot takes ___ to become effective.

Please Select an Answer.
Correct
Wrong

You’re not immediately protected

It takes about two weeks after you get the flu vaccine for the body to develop antibodies that protect against the virus. Some people think the flu shot can actually give you the flu; in reality, people were likely exposed to the flu virus before their flu shot became effective.

QUESTION 6

For the best protection, you should get the flu vaccine ___.

Please Select an Answer.
Correct
Wrong

The flu is different every year, so you need a new vaccine every year

New strains or types of flu viruses cause epidemics each flu season, and the experts specifically design the flu vaccine to respond to those strains. Last year’s flu shot may not protect you from the flu this year. To avoid the flu, get your flu shot each year. One amendment to this guideline: Children getting the flu vaccine for the first time should get two doses that first year only.

7/10
QUESTION 7

The best time to get the flu vaccine is by ___.

Please Select an Answer.
Correct
Wrong

Beat the epidemic

Getting the flu shot before the end of October will not only reduce your chances of coming down to the bug, but it will also help stop the flu from spreading throughout your community. This is especially important to protect infants who are too young to get the flu shot themselves. That said, the phrase “better late than never” definitely applies here. The flu season can last until May, so you can still benefit from getting the flu shot even after peak season.

QUESTION 8

Pregnant woman ___ get the flu vaccine.

Please Select an Answer.
Correct
Wrong

The shot can protect both mother and baby

The flu vaccine is not only safe for pregnant women, but it can also reduce the chances of getting the flu for both the mother (during and after childbirth) AND the baby after birth. That’s because mom can pass antibodies on to the new baby during pregnancy. Since infants cannot get the flu shot until six months, this protection from flu could be lifesaving.

9/10
QUESTION 9

Symptoms of the flu usually come on ___; cold symptoms usually begin ___.

Please Select an Answer.
Correct
Wrong

Onset of viral symptoms can be a clue

The flu and the common cold can share a few key symptoms, which can sometimes make it tricky to tell them apart. In general, the flu symptoms tend to begin abruptly, but signs of the common cold build up slowly over days. Another clue? The flu is more severe and often comes with muscle aches and weakness. The cold also tends to bring stuffy and runny noses, which is less common for the flu.

10/10
QUESTION 10

You ___ develop natural immunity to the seasonal flu after being exposed to it once.

Please Select an Answer.
Correct
Wrong

The flu “shifts” every year

Viruses that cause influenza have frequent genetic changes. Being exposed to last year’s flu will not necessarily make you immune to this year’s flu. It’s true that your body may hang on to antibodies that would protect you from that specific strain of the flu, but each year’s flu epidemic has different variations. In general, exposure to germs can be healthy for the immune system, but the influenza virus is an example of one nasty bug you don’t want in your body. Vaccination is key.
