Was the flu ever considered a pandemic?

What flu is going around 2020?
Influenza B Strain Dominating Early in the 2020 Flu Season.
Why does flu keep coming back?
These viruses spread seasonally each year because of a phenomenon known as antigenic drift: They evolve just enough to evade human immune systems, but not enough to develop into completely new versions of the virus. The H3N2 subtype causes the most disease each year.
How long is the flu B contagious?
Typically, 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 and people with weak immune systems may shed the virus even longer.

How long does flu B last in child?
How Long Does Flu in Children Last? In most children, the fever and most other symptoms usually are gone in five days or less. Sometimes the cough and weak feeling may go on for one to two weeks. If complications such as pneumonia develop, then illness may last two weeks or more.
Can child get flu twice?
Sadly, the answer is yes. As awful as it sounds, it is possible to get the flu twice in one season because there are two different types of the virus. “A child could be infected by both influenza A and influenza B in the same year,” Dr. Ian Tong, chief medical officer at Doctor on Demand told POPSUGAR.
Can you get influenza B twice in a year?
Unfortunately, no. 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.
How does flu B spread?
The illness results from a virus that spreads very easily from person to person. Someone can contract the virus by coming into close contact with a person who has the infection or by touching a surface that the person has touched, then touching their own mouth or nose.
Why isn’t the flu considered a pandemic?
An influenza pandemic is a global outbreak of a new influenza A virus. Pandemics happen when new (novel) influenza A viruses emerge which are able to infect people easily and spread from person to person in an efficient and sustained way. The United States is NOT currently experiencing an influenza pandemic.
How long did influenza pandemic last?
The influenza pandemic of 1918–19, also called the Spanish flu, lasted between one and two years.

Can you get a relapse of the flu?
However, for medical providers it is less about the flu (no disrespect to all of you suffers), but the “relapse” which some have one to two weeks after they recover which is the big concern. That is likely not a relapse, but rather pneumonia.
When should I be concerned about influenza B?
