Hong Kong recorded nine new coronavirus cases today, the first time in single digits since July 3.
While this was good news, Dr Chuang Shuk-kwan of the Centre for Health Protection cautioned it was too early to tell if restrictions on social distancing should be lifted, such as allowing customers to eat dinner in restaurants.

Nevertheless, there was one curious case -- the world's first -- that shows even if someone has recovered from Covid-19, they can be reinfected again.
Case #564 is a 33-year-old IT worker who was infected with the coronavirus in April but only had mild symptoms and then recovered.
In early August he flew to Spain for a trip and when the man returned to Hong Kong he had no symptoms but tested positive for the virus again.
Researchers from the University of Hong Kong wanted to find out if he was a "persistent carrier" from his previous infection. But it turns out from gene sequencing that the second strain was markedly different from the first. The second strain matched those found in Europe during July and August.
"Many believe that recovered Covid-19 patients have immunity against re-infection because most developed a serum neutralizing antibody response. However, there is evidence that some patients have waning antibody level after a few months," the researchers said in their study that was accepted by the Clinical Infectious Diseases journal.

The researchers suggested recovered patients should continue wearing masks and should also consider getting vaccinated.
This new development puts a damper on hope that once this was all over we'd all be fine. Nope. The possibility of re-infection is real and possible.
Get used to wearing masks, folks. This virus is in it for the long haul.
I just got an update that Thailand will be open to visitors in October, but they would still have to quarantine for two weeks before being let loose in the Kingdom of Smiles... how many visitors are actually going to go?
