According to Chinese health authorities, the latest coronavirus can be transmitted between men. It also adapts and mutates that can make the spread of the virus quicker and perhaps harder to treat. The contagious existence of the virus is not yet apparent. Although many other coronaviruses are spread by coughing and sneezing, the virus is not spread by the respiratory tract.
In Chinese city Wuhan, the first diseases have been identified and are now shut down to a wild animal and fish market. The virus may have been transmitted via direct human-animal contact or just airborne contact like many germs.
So-called zoonotic diseases are caused by viruses that can spread between humans and animals. These viruses can be transmitted through human consumption of meat or animal products— or by inadequate heating, or manufacture of such items in an unhealthy environment.
Fever, shortness of breath and coughing in patients who contract the virus are more likely to adopt the virus. Air sacs in the lungs and filling them with fluids or pus can be inflamed by the virus often causing pneumonia. Elderly people are more likely than young people to be infected by the virus.
Coronaviruses are highly adaptable, genetically diverse as RNA viruses. It means that they can spread easily between different species and infect them. Some coronaviruses can cause the usual cold. Other diseases, which lead to breathing difficulties, pneumonia and even death, can become more serious.
Airports all over the world, especially in China, have introduced fever checks for Chinese passengers.
As always, good hygiene and caution are advisable, e.g. it is advisable to avoid close contact with those with acute respiratory infections, or wildlife or livestock dead or alive. It is best to wash your hands after direct contact with a patient.
