Effect of h1n1 swine virus on humans
Although swine flu doesn't typically affect humans, there was a global outbreak (pandemic) in 2009–2010, the first flu pandemic in more than 40 years it was caused by a then-new flu virus known as h1n1, a type a influenza virus that's a combination of swine, avian (bird), and human genes that mixed together in pigs and spread to humans. Although the 2009 h1n1 “swine influenza” virus has not been identified in us human medicine to quantify the effect of interventions that reduce the severity. In fact, although the term swine flu is often used to describe the outbreak, the official term for the 2009 virus is novel h1n1 influenza it is important to realize that the influenza virus changes (mutates) constantly so that there are many strains of h1n1 that differ subtly from each other. What is h1n1 (formerly known as swine flu) according to the ministry of health (moh) , it is a respiratory disease affecting pigs that is caused by the type a (h1n1) influenza virus similar to influenza outbreaks in humans, h1n1 very rarely affect humans but sporadic human infections do occur.
The h1n1 virus has resulted from a triple recombination containing genes from human, avian, and swine influenza virus [12,13] the incidence, clinical characteristics and factors affecting the patients outcome of the first wave have been well described in previous published studies [ 14 - 17 ]. The cdc has determined that novel h1n1 virus is contagious and is spreading from human to human spread of novel h1n1 virus is thought to occur in the same way that seasonal flu spreads flu viruses are spread mainly from person to person through coughing or sneezing by people with influenza. It would be most disturbing if the 2008 h1n1 human virus were to reassort with the new swine/human virus, as we could then be facing a more drug-resistant pandemic strain of influenza, treatable .
The influenza a virus subtypes that occur in humans – h1n1, h3n2 and h1n2 – are enzootic in swine populations worldwide pigs are also susceptible to h5n1 hpaivs under natural and experimental conditions, but there is a clear species barrier as appears to be the case for humans  ,  ,  . Continued that makes it a human flu virus to distinguish it from flu viruses that infect mainly pigs and from the seasonal influenza a h1n1 viruses that have been in circulation for many years . Swine influenza (swine flu) is a respiratory disease of pigs caused by type a influenza virus that regularly causes outbreaks of influenza in pigs swine flu viruses do not usually infect humans, but rare human infections have occurred. Swine flu, medically named h1n1 influenza a, was first detected in humans in april 2009 the virus infects the respiratory system and can be fatal. Current research suggests that pandemic h1n1 influenza of swine origin has distinct means of transmission from the seasonal flu, yet does not result in the pathogenic severity of avian flu viruses .
The h1n1 swine flu virus, like the seasonal flu virus, can become airborne if you cough or sneeze without covering your nose and mouth, sending germs into the air. But then we started seeing pigs infected with human pandemic swine flu, now studying h1n1 and seasonal flu vaccines effects here could only have started since the end of august, when seasonal . A person can catch swine flu through contact with infected pigs or other people of swine flu that infected humans was of the h1n1 subtype better protected against the harmful effects of . The 1918 flu pandemic in humans was associated with h1n1 and influenza appearing in pigs this may reflect a zoonosis either from swine to humans, or from humans to swine although it is not certain in which direction the virus was transferred, some evidence suggests, in this case, pigs caught the disease from humans .
Effects of the s42 residue of the h1n1 swine influenza virus ns1 protein on interferon responses and virus replication human influenza virus, specific amino acids . The influenza a virus non-structural protein 1 (ns1) is a multifunctional protein that plays an important role in virus replication, virulence and inhibition of the host antiviral immune response in the avian influenza virus or human influenza virus, specific amino acids of ns1 have been shown to . Swine flu is a respiratory disease caused by influenza viruses that infect the respiratory tract of pigs and result in a barking cough, decreased appetite, nasal secretions, and listless behavior the virus can be transmitted to humans. This page contains background information about swine influenza virus infections in humans, now called “variant virus infections in humans” what is swine influenza swine influenza (swine flu) is a respiratory disease of pigs caused by type a influenza viruses that regularly cause outbreaks of influenza in pigs. Swine flu symptoms similar to those of human flu regularly affect pigs people who are around pigs are most likely to suffer from the h1n1 virus but it is also possible for the virus to spread .
Effect of h1n1 swine virus on humans
After multiple discrete introductions of influenza a(h1n1)pdm09 virus into sri lanka, the virus was transmitted among humans, then swine the spread of virus between geographically distant swine farms is consistent with virus dispersal associated with a vehicle used for swine transportation, although this remains unproven. Swine flu seems to have made this step and can be transmitted readily from human to human how is swine flu caught despite being referred to as swine flu, the h1n1 flu virus is not caught by eating pork. Swine flu, also known as the h1n1 virus, is a relatively new strain of an influenza virus that causes symptoms similar to the regular flu it originated in pigs but is spread primarily from person . The influenza virus usually affects the elderly the a/h1n1 swine flu has turned out to be far less deadly than was initially feared h1 in humans reappeared .
- Swine influenza was a disease related to human flu during the 1918 flu pandemic, when pigs became ill at the same time as humans the first identification of an influenza virus as a cause of disease in pigs occurred about ten years later, in 1930.
- Swine flu and the current influenza a (h1n1) pandemic in humans: a review preventive measures and the current pandemic situation in humans key words: h1n1 virus, human, influenza a, pandemic .
- In 2006 the american association of swine veterinarians reported that humans were passing their h1n1 viruses to pigs, causing widespread illness in swine herds, especially in the american midwest.
Potential farm sector effects of 2009 h1n1 “swine flu”: questions and answers congressional research service 2 emphasized that humans cannot get 2009 h1n1 flu, or any other type of flu, from eating pork or.
