New type of Avian influenza virus
New type of Avian influenza virus - Outbreaks of Avian influenza had horrendous world a few years ago. Now in China, emerging new type of Avian influenza virus which has attacked nine people. 3 One of them was saved. Well, there are a few things to know about this new type of bird flu.
Strain or a new type of Avian influenza virus by researchers called the H7N9 virus. So far, the virus has already claimed casualties were 3 people in China, which is 2 people in Shanghai and Zhejiang province 1.
The following are some things to note from the new virus:
1. H7N9 virus has never attacked humans before
H7N9 virus strain is known to be found in poultry or birds, but initially did not cause disease in humans. Most of the strains of the bird flu virus does not infect humans.
Nevertheless, there are exceptions to the H5N1 bird flu virus that has made more than 600 diseases in humans in 15 countries since 2003.
2. With the same strain of virus can infect humans
In a report published the Journal of Virology, family strains of the flu H7 virus has caused more than 100 cases of human infection during the last 10 years. Eg H7N7 strain of the virus that had become epidemic in 2003 in the Netherlands and infecting 89 and claimed the first casualties.
"The letter 'H' and 'N' in the name refers to the virus proteins on the surface of the virus called hemagglutinin and neuraminidase. There are 16 types of hemagglutinin and 9 neuraminidase types that can appear in a variety of combinations," said Dr. Richard Webby, a bird flu expert and researcher Hospital St. Jude Children's Research Hospital.
3. Symptoms of the flu H7 virus infected
According to WHO, the three victims died from Avian influenza infection in China the latest types of respiratory tract infections which can lead to pneumonia and respiratory distress. Most of H7 influenza virus infections can be seen from the appearance of conjunctivitis or eye infection that is not contagious among humans.
4. Is it true that H7N9 virus can be transmitted from human to human?
According to the WHO, to date, there is no evidence that this new H7N9 strain can spread between humans. In the case of China, it seems the cases are not related. People are close and never made contact with the victim is also not infected. But the WHO still trying to unravel certainty.
This virus has genetic markers that can be expected to infect humans. Could be a marker but it only appears when a virus has infected human. If viruses in animal populations also have this marker, should be the case that humans can attack more,
5. Way of spreading the H7N9 virus
Researchers strongly suspected that H7N9 has a population of sources. But whether it is a bird populations or other organisms, still need further research. There are many animals that can allegedly infected, but only a small percentage of cases where the H7N9 virus jumped to humans.
