'S' hooks used to deliver food boxes to guests is believed to be behind virus spread |
“S” hooks used to deliver food to people quarantined at the Ramada Hong Kong Grand Hotel in Tsim Sha Tsui may have caused a mutated form of the coronavirus to spread among at least three people quarantined there.
This was disclosed today, Apr 20, by Dr Chuang Shuk-wan of
the Centre for Health Protection during the regular press briefing on the
latest coronavirus situation in

Chuang reported eight additional Covid-19 cases classified
as three imported, four local, and one unclassified, referring to a 56-year-old
woman who was on home quarantine after arriving from
The CHP official said that investigations into the case of the 29-year-old man classified as the first local case found to have the N501Y variant showed he could have been part of a cross-contamination that occurred at Ramada TST where he stayed for his 21-day quarantine.

Two other patients who had stayed on the same floor of the hotel during the time the Indian man was there were also found to have an almost identical genetic sequencing of the South African variant he carried.
Both patients were foreign domestic helpers, one a Filipina, and the other, Indonesian. One of them stayed in a room next door to the man, the other farther down the corridor.

As there were no signs that the virus could have spread through the hotel air conditioning system or the water pipes, Chuang said investigators concluded the virus could have spread through the hooks used for food delivery.
These “S” hooks were reportedly used to hang plastic bags containing the food delivered to guests, and which they also used to return lunch boxes used after each meal.

“We suspected that the hooks were the source of cross infection,’ Chuang said.
She also disclosed that around 10 guests who had stayed on the same floor of the hotel since January had been found to have the variant. Experts are now doing genome sequencing on these cases to see if they were part of one big cluster.

Since this discovery, all hotels have been told to stop using the hooks for delivering food to guests, she added.

The Indonesian arrived on Mar 20, and after ending her 21-day quarantine, had moved into her employer’s house in Yau Tong. She was found infected on Apr 18, after submitting to compulsory testing.
The same transmission mode is suspected to have caused the virus to spread among three guests at Ramada Grand View in North Point earlier in March.

Because of this finding, everyone who had stayed in rooms on the same floor of Ramada TST from Mar 19 to Apr 9, when the index case was there, was moved to quarantine “just in case they were exposed to the same risk,” said Chuang.

The other imported cases today include two who were found
infected while staying at Ramada in North Point. One is a 38-year-old FDH who

He was in the same Vistara flight, UK6395, where a total of 53 passengers have so far tested positive for Covid-19, said Chuang.
The third imported case is a two-year-old girl who had flown
in from
Two other local cases, as well as the unclassified one, all live in Tsuen Wan, where a rash of cases with unknown sources has been reported recently. This prompted Chuang to admit that there seems to be an invisible transmission going on in the district.
The two local cases who live there are both women. One is 57
years, and the other, a 46-year-old who arrived from Shenzhen on Apr 6 and had

Chuang said this was “quite likely an imported case but could also be local because there were some family members who were going in and out” of the house where she was staying.
The last local case involves a 41-year-old male construction worker who lives in Tai Wai.
No preliminary cases were reported.
