Remain vigilant after Covid reminds us it has never gone away
Just as the devastating Covid-19 outbreak seemed like a distant memory, the Hong Kong public has been rudely reminded that the killer virus has never really gone away. The disturbing headline of positive samples hitting a one-year high, along with 30 deaths in the past four weeks, calls for greater vigilance, especially from those who are weak and vulnerable.
The Centre for Health Protection issued an alert after the proportion of respiratory samples testing positive rose from 6.2 per cent to 13.7 per cent in the four weeks since early April. Positive samples from sewage tests and patients at clinics and public hospitals have also increased.
Thankfully, there are suggestions the coronavirus that once wreaked havoc in the city has become much milder. With most people having either been vaccinated or infected, or both, during the five main waves of the virus between 2020 and 2023, medical experts believe the general public needs not rush for booster shots.
That is not to say Covid-19 infection is now so mild that it can be ignored. While the number of severe cases and deaths did not follow the increasing trajectory of positive samples, there were 30 deaths among 81 severe adult cases in the weeks concerned.
Epidemiological investigations found that 83 per cent of the severe cases involved patients aged 65 or older, with more than 90 per cent having pre-existing health conditions. Earlier, a 17-month-old girl and a 13-year-old girl also became seriously ill. Meanwhile, some first-time Covid patients have also reportedly suffered from strong flu symptoms.
There may be no cause for panic at this stage, but health officials have warned that Covid cases could continue to remain high in the coming weeks. It would do well to stay alert, particularly those who are vulnerable such as young children, the elderly and chronically ill. It is estimated that of those aged 65 or above, some 75 per cent living in homes for the elderly and 90 per cent living in the community are yet to receive a booster.

Drunk Chinese man swallows spoon, thinks it was a dream, finds out mishap 5 months later
A Chinese man accidentally swallowed a coffee spoon while intoxicated in Thailand, believing it to be merely a dream for several months. Advertisement The 29-year-old, known as Yan, visited a doctor in Shanghai in June, suspecting he had ingested plastic while eating takeaway food. However, instead of plastic, the doctor at Shanghai Zhongshan Hospital discovered a 15cm long spoon lodged within him. The spoon was trapped in his duodenum – the first section of the small intestine. It was positioned precariously; even a slight movement could cause perforation of the intestine, resulting in inflammation or severe bleeding. The spoon became lodged in his duodenum, the initial section of the small intestine. Photo: It was at this point that Yan realised his experience in Thailand back in January was not a figment of his imagination.

Indonesia's hantavirus cases spark calls to eradicate rat infestations
A string of hantavirus-linked cases reported in Indonesia has sparked fears that the potentially lethal virus could be spreading undetected, with health experts citing widespread rodent exposure and poor sanitation as major risks that could lead to a further spike. Advertisement Eight cases of haemorrhagic fever with renal syndrome (HFRS), one of the diseases caused by the hantavirus, have been confirmed across four provinces – Yogyakarta, West Java, East Nusa Tenggara and North Sulawesi – as of June 19, according to a statement released by the health ministry on Saturday. All patients infected with HFRS have since recovered. While there is no need for public alarm at this stage, health experts recommend strengthening disease surveillance and ramping up public education efforts, noting that the virus could be silently spreading in high-risk areas. What is hantavirus? According to the Indonesian health ministry, hantavirus-linked diseases are transmitted by animals. 'This disease is transmitted through direct contact with rodents, and based on existing research, there has been no human-to-human transmission.' HFRS, the disease detected in Indonesia, primarily affects the kidneys and has been reported elsewhere in Asia and Europe. Hantavirus pulmonary syndrome (HPS), the other common disease caused by the virus, affects the lungs and is more prevalent in the Americas. HPS recently hit the headlines when it was reported that Betsy Arakawa, the wife of the late Hollywood actor Gene Hackman, had succumbed to the disease after she was found dead alongside her husband at the American couple's home in New Mexico in February this year. The hantavirus pulmonary syndrome was in the news recently following the death of Hollywood actor Gene Hackman and his wife Betsy Arakawa in Februay.
