What’s worse flu A or B?
Another key difference between influenza A and B.
While influenza B viruses are typically less common than influenza A viruses, influenza B infections can be more severe in children, and can lead to complications that require hospitalization or death..
When was the last pandemic flu?
The most recent pandemic occurred in 2009 and was caused by an influenza A (H1N1) virus. It is estimated to have caused between 100 000 and 400 000 deaths globally in the first year alone.
What animal did the 1918 flu come from?
The virus that caused the 1918 influenza pandemic probably sprang from North American domestic and wild birds, not from the mixing of human and swine viruses.
How long was the swine flu outbreak?
The 2009 swine flu pandemic was an influenza pandemic that lasted for about 19 months, from January 2009 to August 2010, and was the second of two pandemics involving H1N1 influenza virus (the first being the 1918–1920 Spanish flu pandemic).
Was h1n1 the same as the Spanish flu?
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
How long did the 1918 flu last?
While the global pandemic lasted for two years, a significant number of deaths were packed into three especially cruel months in the fall of 1918.
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.
How does swine flu differ from other flus?
Swine flu is more likely to include diarrhea and vomiting, as well as the respiratory symptoms that come with typical seasonal human flu. Recent reports indicate that the A(H1N1) swine flu virus infects deeper into the lungs than typical seasonal human flu.
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 flu is going around now?
Nationally, influenza A(H1N1)pdm09 viruses are now the most commonly reported influenza viruses this season. Reporting of genetic and antigenic characterization and antiviral susceptibility of influenza viruses has been stopped and will resume with the 2020-2021 season.
What American city was one of the hardest hit by the 1918 flu?
PhiladelphiaPhiladelphia was the hardest-hit city in the United States. After the Liberty Loan parade (celebrations to promote government bonds that helped pay for the Allied cause in Europe) on September 28, thousands of people became infected.
Does the Spanish flu still exist?
Descendants of the 1918 influenza virus still circulate today, and current seasonal influenza vaccines provide some protection against the 1918 virus.
What is the difference between influenza A and h1n1?
Flu (influenza) viruses are divided into four broad categories: influenza A, B, C or D. Influenza A is the most common type. H1N1 flu is a subtype of influenza A. Subtypes of influenza A are categorized based on two proteins on the surface of the virus, hemagglutinin (H) and neuraminidase (N).
What strain of flu is going around 2020?
