Is Flu A or B worse?
In the past, it was thought that infection with influenza A was more severe than infection with influenza B. However, a 2015 study in adults with influenza A and influenza B found they both resulted in similar rates of illness and death.
Can you get h3n2 twice?
While you can’t catch the same strain twice — as your body will develop antibodies to the virus — you can get another strain if you’re not immunized.
Where did the Spanish flu start?
While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on March 11, 1918.
Is h3n2 swine flu?
While this H3N2 variant is also a type of swine flu, it’s not the same strain that caused the 2009 swine flu pandemic. “The 2009 pandemic was caused by a new subtype of H1N1 that’s become a regularly circulating flu virus since 2009,” a CDC spokesperson told Healthline.
What do the H and N stand for in flu?
Influenza A viruses are classified by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2).
Where did h1n2 come from?
For at least 80 years, influenza viruses known as “classical swine H1N1” viruses have circulated in North American pigs. However, in the late 1990s, a series of reassortment events occurred between influenza viruses found in pigs, humans and birds.
Is h1n1 same as bird flu?
Examples include avian influenza “bird flu” virus subtypes A(H5N1) and A(H9N2) or swine influenza “swine flu” virus subtypes A(H1N1) and A(H3N2). All of these animal influenza type A viruses are distinct from human influenza viruses and do not easily transmit among humans.
How long did the h3n2 virus last?
The 1968 flu pandemic was a global outbreak of influenza that originated in China in July 1968 and lasted until 1969–70.
What is the medical name for the flu?
Influenza . Also called the flu, it’s a common but sometimes serious viral infection of your lungs and airways. It can cause congestion, fever, body aches, and other symptoms.
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.
Is Tamiflu worth taking?
If you’re in good health and come down with the flu, you don’t necessarily need Tamiflu or another antiviral medication, because you’ll most likely get better on your own within one to two weeks using self-care strategies, such as resting, getting plenty of fluids, and taking over-the-counter pain relievers for fever, …
What does h1n1 stand for?
The designation “H1N1” indicates unique traits, which exhibit characteristics that identify the virus to the immune system and allows for attachment and replication of the virus. The “H” (hemagglutinin) and the “N” (neuraminidases) are both proteins that are found on the outer shell or envelope of the virus.
Is h3n2 worse than h1n1?
Conclusions: Influenza A H3N2 infection was more severe than A H1N1 or B in terms of fever, leukopenia, and C-reactive protein. Myalgia and other symptoms such as fever, headache, general malaise and sore throat were equally frequent in influenza A H3N2, A H1N1, and B infections.
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.
