How much did the swine flu kill?
Between April 12, 2009, and April 10, 2010, the CDC estimates swine flu caused 60.8 million illnesses, 273,304 hospitalizations and 12,469 deaths in the U.S..
Is swine flu still around?
In 2009, H1N1 was spreading fast around the world, so the World Health Organization called it a pandemic. Since then, people have continued to get sick from swine flu, but not as many. While swine flu isn’t as scary as it seemed a few years ago, it’s still important to protect yourself from getting it.
Can bird flu infect humans?
Although avian influenza A viruses usually do not infect people, rare cases of human infection with these viruses have been reported. Infected birds shed avian influenza virus in their saliva, mucous and feces.
What year was the bird flu epidemic?
The year 2005 has been dubbed ‘the year of bird flu’. Across the globe, the fear of avian influenza has caused government officials to place a higher priority on developing plans to deal with pandemic influenza.
Why is h5n1 so deadly?
In 1997, avian influenza virus (H5N1) caused severe human disease in Hong Kong. One of 9 infected children and 5 of 9 infected adults died. Investigators hypothesized that this virus is lethal because it induces an unusually potent proinflammatory cytokine response.
What country did swine flu come from?
The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents. Six of the genes are closest in sequence to those of H1N2 ‘triple-reassortant’ influenza viruses isolated from pigs in North America around 1999-2000.
When was the last pandemic 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.
What is the mortality rate of the flu in the United States?
While the impact of flu varies, it places a substantial burden on the health of people in the United States each year. CDC estimates that influenza has resulted in between 9 million – 45 million illnesses, between 140,000 – 810,000 hospitalizations and between 12,000 – 61,000 deaths annually since 2010.
Can h5n1 be cured?
It’s suspected that infection can spread from wild fowl to domestic poultry. Because the disease has spread to wild birds, pigs, and even to donkeys, it will be difficult, if not impossible, to eradicate.
How long did bird flu last?
Globally, from January 2003 to 15 October 2020, there were 861 cases of human infection with avian influenza A(H5N1) virus reported from 17 countries. Of these 861 cases, 455 were fatal (CFR of 53%). The last case was reported from Nepal on 30 April 2019 (source).
Does bird flu have a vaccine?
There is currently no vaccine available to the public. The government does have a supply of a vaccine for one type of H5N1 bird flu virus and could distribute it if there was an outbreak that spread easily from person to person.
Is bird flu still a threat?
While bird flu usually poses no threat to humans, instances of transmission of bird flu to humans have been reported since 1997, and over 100 people were infected in an outbreak that began in Southeast Asia in mid-2003.
How many people died from the bird flu?
In the US alone, 675,000 people died from this influenza strain.
What is the mortality rate of the bird flu?
Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60%.
Can bird flu kill you?
Although bird flu may kill more than half the people it infects, the number of fatalities is still low because so few people have had bird flu. Fewer than 500 bird flu deaths have been reported to the World Health Organization since 1997.
How did bird flu start?
Although there are several types of bird flu, H5N1 was the first avian influenza virus to infect humans. The first infection occurred in Hong Kong in 1997. The outbreak was linked to handling infected poultry. H5N1 occurs naturally in wild waterfowl, but it can spread easily to domestic poultry.
How long did the Spanish flu outbreak 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. Historians now believe that the fatal severity of the Spanish flu’s “second wave” was caused by a mutated virus spread by wartime troop movements.
