Parts of China are on lockdown, a small number of cases have been reported in other countries and the past week has brought widely conflicting views on the potential danger presented by the new virus. \nWe look at the scientific facts, analyse why it\u2019s so difficult to predict the spread of the virus, look at the nature of virus infection and discuss why treatments such as vaccines are not available. \nWe look at why some viruses can jump from animals to humans and examine hi-tech solutions designed to speed up the process of drug development.
