Houghton says it doesn't make sense to look for patient zero. For example, in the 1980s, when the AIDS epidemic broke out, many people wanted to find AIDS patients No. 0, and spent a lot of energy*ed widespread discussion. But many years later, it was found that this person was not patient zero. Looking for patient No. 0 may lead to stigmatization and discrimination, which can not play any role and is not scientific.

But on the other hand, we really need to understand the origin of the virus, where it comes from, and its transmission process, so as to reduce the risk of transmission to human beings.

Horton said that the World Health Organization defined the outbreak as an international public health emergency on January 30, which is a warning to the world and reminds the world to pay attention to the epidemic* and prepared everyone*anization in the field of global health. We need to pay attention to who's warning*ands of deaths, which could have been avoided.
