1.Coronavirus
Why in news? New virus identified as agent in China disease outbreak. More about the virus:
Coronaviruses are a specific family of viruses, with some of them causing less-severe damage, such as the common cold, and others causing respiratory and intestinal diseases. A coronavirus has many regularly arranged protrusions on its surface, because of which the entire virus particle looks like an emperor’s crown, hence the name “coronavirus”. Apart from human beings, coronaviruses can affect mammals including pigs, cattle, cats, dogs, martens, camels, hedgehogs and some birds. They are RNA viruses and have high genetic variability, meaning they can easily overcome barriers between different species. So far, there are four known disease-causing coronaviruses, among which the best known are the SARS corona virus and the Middle East Respiratory Syndrome (MERS) coronavirus, both of which can cause severe respiratory diseases. How is the virus transmitted?
Virus can be transmitted through direct contact between animals and humans as well as like with many germs simply through the air, such as by coughing or sneezing. But there are many other ways of infection, for example through food or vectors. A mosquito, tick or other insect can transport a pathogen from the host to another organism without becoming ill itself.
