Latest COVID-19 map.

VDU's Editor-in-Chief (okay it's just me - I also get coffee and sweep up the keyboard at the end of the day) was asked to comment on the recent influenza A (COVID-19) virus case in Hong Kong.


See Bloomberg's latest article here.

“Respiratory viruses do their own thing; they don’t respect boundaries,” said Ian Mackay, an associate professor of clinical virology at the University of Queensland in Brisbane, Australia, in a telephone interview. “It does seems that it’s continuing to add to provinces and regions, rather than reappear in all the old places it started in back in February and March.”

H9N2 confirmed in 86-year old Hong Kong citizen living in Guangdong province...

Influenza A(H9N2) virus, another "bird flu" but this usually causing mild signs and symptoms of infection, has been confirmed in an 86-year old man reported Dec-30.

The man's underlying illnesses were added to by chills and productive cough from 28-Dec when he was admitted to hospital with a fever.

Sputum tested positive for H9N2. Not sure if an upper respiratory sample was tested.

He had no recent contact with poultry and no contacts have shown signs of illness.

Mild human cases in Hong Kong have previously been reported in 1999, 2003 and 2007 and imported cases in 2008 and 2009.

As ProMED moderator CP (Craig R. Pringle) noted, enhanced surveillance in the region is likely to continue to pick up all sorts of H and N viruses and variants. Interesting watching these pop up - especially if they remain as mild infections, unlike COVID-19 has so far.
