H1N1 Influenza Pandemic In 2009

(Swine Flu)

The H1N1 influenza pandemic in 2009 is caused by a new strain of H1N1 influenza A virus, which is genetically a combination of swine, bird and human influenza viruses.

In most cases, the pigs have been infected by strains of influenza that of those who become infected people slightly differ. These strains are spreading very rare in humans, and if they do, they rarely spread from person to person. The H1N1 swine flu virus is a combination of swine, avian and human influenza viruses that spread easily from human-to-human spread the infection is not acquired by eating pork and very rarely through contact with infected pigs.

In most cases, the pigs have been infected by strains of influenza that of those who become infected people slightly differ. These strains are spreading very rare in humans, and if they do, they rarely spread from person to person. The H1N1 swine flu virus is a combination of swine, avian and human influenza viruses that spread easily from human-to-human spread the infection is not acquired by eating pork and very rarely through contact with infected pigs. In June 2009, the World Health Organization declared the swine flu H1N1 as a pandemic; it spread to> 70 countries and all 50 US states. The majority of deaths occurred initially at in Mexico. The morbidity and mortality rate for H1N1 swine flu are – unlike the saiaonalen flu – higher among young people and middle-aged adults, and lower in the elderly. The pandemic has passed in August 2010 in the postpandemische period. Subsequently, the virus name was influenza A (H1N1) standardized pdm09 to refer to the pandemic, and to distinguish the virus from seasonal H1N1 strains and the H1N1 strain of the pandemic of the 1918th Human cases of H3N2 virus infections are sporadic occurred in several US states where children and adults have had at agricultural fairs contact with apparently healthy domestic pigs. There were also cases of possible human-to-human transmission. The H3N2 virus has genes from avian, swine and human viruses and the matrix (M) gene from the A (H1N1) virus pdm09. Symptoms and discomfort symptoms, signs and complications are similar to those of ordinary flu (influenza: Symptoms and complaints), although nausea, vomiting and diarrhea occur more frequently. The symptoms are usually weak, but they can worsen and lead to pneumonia or respiratory distress syndrome. Currently circulating isolates appear to have partially lost their initial virulence. Sometimes diagnostic PCR tests of respiratory specimens Since A (H1N1) pmd09 swine flu is the predominant influenza strain currently circulating worldwide, this diagnosis should be considered in any patient with influenza-like symptoms into consideration. A PCR test can (H1N1) virus pmd09 recognize A in samples from the respiratory tract (eg. B. nasopharyngeal swabs, Nasalwaschungen, aspirates the air tube). Slightly ill patients require no testing except for epidemiological or monitoring, but the requirements of the local hospitals and public health may vary. Rapid antigen tests have low sensitivity and are for the diagnosis generally only be clinically useful if the results are positive. Therapy Sometimes a neuraminidase inhibitor Treatment mainly focuses on relieving symptoms (eg. As acetaminophen or ibuprofen for fever and pain). Antiviral drugs can be used, especially in patients at high risk (Influenza: Risk groups) and seriously ill. Oseltamivir and zanamivir seem to be effective and are most effective when initiated with them within 48 hours after symptom onset. In the US, the FDA has issued instructions for the use of oseltamivir in emergency situations in patients <1 year and the emergency use of peramivir, an i.v. Neuraminidase inhibitor, published in critically ill patients in the hospital. Most patients recover completely without taking this medication. Prevention The current seasonal influenza vaccines against the A (H1N1) virus pdm09 effective. Reasonable steps (for example, stay at home when developing flu-like symptoms;. Thorough, frequent hand washing with soap and water or an alcohol-based hand sanitizer) are recommended to reduce the spread of infection.
