• Fever
• Cough
• Shortness of breath
This is dependent on what was historically known as MERS
virus incubation period. The amount of time it takes for signs
to occur after an infected person can be critical for prevention
and control. Identified as the duration of incubation, this time
helps health officials to isolate or track individuals who may
have been exposed to the virus. Nevertheless, if the incubation
period is too long or too short, then it may be difficult to
implement such steps.
Many diseases, such as influenza, have a brief two to threeday
incubation period. Until they show flu symptoms, people
can shed infectious virus particles, making it almost
impossible to recognize and isolate people who have the virus.
Nevertheless, SARS had an incubation period of about five
days. It also took four to five days after symptoms started
before the virus could be spread to sick people, which gave
officials time to stop the infection, and contain the outbreak
effectively.
Executives at the Centers for Disease Regulator and
Prevention say the incubation period for the current corona
virus is 2-14 days. But whether a person can spread the virus
before symptoms occur is still not clear, or whether the nature
of the disease influences how quickly a patient can spread the
virus. This is troubling because it may mean the identification
of the infection will elude.
