What is the issue?
There is a cluster of cases of viral pneumonia in Wuhan, China. As of January 5, 2020, local, provincial, and national health commissions in China have reported a total of 59 cases with no deaths. The cluster is centered at the Wuhan South China Seafood City (also called the South China Seafood Wholesale Market and the Hua Nan Seafood Market). In addition to seafood, the market sells chickens, bats, marmots, and other wild animals. The market has been closed since January 1, 2020, for cleaning and disinfection.
Health authorities in China are monitoring more than 150 close contacts for illness. To date, there have been no reports of spread from person-to-person or to healthcare workers.
Although the cause of this cluster is unknown, there is concern and reports that the cause is a novel coronavirus. Local authorities have reported negative laboratory results for seasonal influenza, avian influenza, adenovirus, and two specific coronaviruses known to cause respiratory illness (severe acute respiratory syndrome [SARS] and Middle East respiratory syndrome [MERS])..
Who is at risk?Only people who have travelled to Wuhan, China are considered to be at risk currently. Travelers to other areas of China, or contacts of travelers to Wuhan are not considered to be at risk. This information may change as more becomes known about the characteristics of the virus.
Symptoms and transmission
Reported symptoms include fever, shortness of breath and bilateral lung infiltrates on chest x-ray.
The current definition for a suspected case in Victoria is as follows:
Travel to Wuhan within 14 days of symptom onset AND fever or history of fever AND respiratory symptoms
This case definition information may change as further information emerges. There have been no reports of spread from person-to-person or to healthcare workers.
Clinicians are asked to be alert for patients of any age presenting with symptoms of pneumonia who meet the suspected case definition above, particularly if they have had contact with the Wuhan South China Seafood City Market. Please ensure that patients presenting with pneumonia to triage are being asked about travel specific to Wuhan, China.
If you have a patient who meets the suspected case definition above:
- Place a surgical mask on the patient.

- Notify the Department of Health and Human Services immediately on 1300 651 160, who will assist with conducting a public health risk assessment and short epidemiological questionnaire for suspected cases.
- Undertake testing in your hospital for alternative causes as soon as possible, in particular for respiratory viruses using multiplex PCR if available;
- After discussion with the Department, you may be advised to take:
- upper respiratory samples (combined nose and throat swabs, or nasopharyngeal swabs)
