Coronavirus is spreading among people who show non-respiratory symptoms. This means detection of the carriers of the virus is going to be extremely difficult, given that nearly all health officials around the world are looking for respiratory symptoms such as coughing, sneezing and breathing difficulties.

Some carriers of this rapidly spreading strain of coronavirus show no fever and no coughing, but instead are exhibiting symptoms of diarrhea, vomiting and chest pains.

"Thus far, official guidance on the symptoms of the Wuhan virus has been limited to fever and symptoms of respiratory illness, such as coughing, difficulty breathing or shortness of breath," reports The Epoch Times:

However, according to local media a report by doctors and experts from Renmin Hospital of Wuhan University on Friday noted the appearance of initial symptoms not related to the respiratory system.

It said that many patients who contracted the virus did not have a fever. Therefore simply taking the temperatures of passengers at transport hubs is not enough to screen for the virus.
