Covid-19 surge: Thai virologist advises vaccination strategy
On Saturday, Yong posted an update addressing public concern about whether vaccination is still necessary. He explained that any disease that can be prevented should be, and while vaccination is one way, other methods like hand washing, mask-wearing, and avoiding crowded places remain important for reducing transmission.
He compared the current situation to the early years of the pandemic when Covid-19 had a high fatality rate (about 1%) and a high rate of severe pneumonia requiring hospitalisation. Now, however, most people have developed immunity either through past infection or vaccination, and the virus itself has become less severe.
As a result, the majority of cases today are asymptomatic or mild—similar to seasonal influenza—except in vulnerable individuals, such as the elderly or those with chronic illnesses.
Yong pointed out that although the severity of Covid-19 and influenza is now comparable, influenza vaccines are still recommended, especially for high-risk groups, because they have been widely used for over 50 years, are inexpensive, and have minimal side effects.
By contrast, current Covid-19 vaccines are expensive—nearly 10 times the cost of flu shots—less effective against new variants, and more likely to cause side effects.
Thus, he does not personally recommend widespread Covid-19 vaccination at this stage, particularly considering the reduced severity of the disease and the cost-benefit balance.
'Those in high-risk groups should still receive flu vaccines, which are subsidised by the government,' he said.
'As for Covid-19, early treatment with effective medication is now a more practical approach than relying on vaccination.' - The Nation/ANN

Dr Sim: Status of Sarawak's first human rabies patient for 2025 unclear
Dr Sim fields questions from reporters after officiating at the 5th International Burn and Wound Conference 2025. – Photo by Chimon Upon KUCHING (July 4): The status of Sarawak's first confirmed human rabies case for 2025 is unclear, said Datuk Amar Dr Sim Kui Hian. The Deputy Premier, who is also Minister of Public Health, Housing and Local Government, said there have been no updates regarding the 13-year-old boy from Kampung Segedup since the case was first reported in May. 'I need to ask the Jabatan Kesihatan (Sarawak Health Department) because I don't think that they want to keep anything in the dark,' he told reporters after opening the 5th International Burn and Wound Conference 2025 here today. He said the Health Department has consistently carried out awareness efforts to educate the public on the risks of rabies. 'You see, the public awareness, right, I think all the Jabatan Kesihatan have always done a lot of public awareness. And that's why, under SDMC (Sarawak Disaster Management Committee), they want to join all these taskforces,' he said. Dr Sim recalled the intense public reaction when rabies was first reported in the state. 'When the first rabies (case happened), at that point in time, everybody panicked. Now it's like okay,' he said. He compared the situation to the Covid-19 pandemic, highlighting that public complacency often follows an initial period of heightened awareness. 'Just like during Covid time, you would not even go near me. But now, even though I read that Covid incidence is increasing, is anybody wearing a mask? Anybody washing their hands? Last time, handwashing was everywhere. Now? Semua lupa (Everyone's forgotten),' he said. He stressed the need for shared responsibility in eradicating rabies. 'The public must play their role and do their part. You must bring your dog for vaccination. You don't expect the government to go to your house to vaccinate,' he said. He also noted that both pet dogs and stray dogs pose similar rabies risks, and that cats are increasingly becoming vectors for the disease. 'There are two things. One is the pet dogs. The pet dogs are causing as much rabies as the strays. And increasingly, the cats. Recently, there was a case involving a cat,' he said, cautioning that cats can contract rabies from dogs and transmit the disease to humans through scratches. The 13-year-old boy's case was confirmed by the Health Department in a Facebook post on May 25. His symptoms were fever, loss of appetite, vomiting, hallucinations, delirium, difficulty walking, and trouble swallowing water from May 21. Investigations revealed that the boy had a history of being scratched by a stray cat, frequently played with and fed stray cats, and had handled the carcass of a cat killed in a road accident. He initially sought treatment at a private hospital before being referred to Sarawak General Hospital (SGH), where clinical tests confirmed he had rabies. At the time of the announcement, the boy was receiving treatment at SGH. Dr Sim Kui Hian human rabies Kampung Segedup lead

Unrest, disease risk not a deterrent for M'sian travellers
At the ready: Thai authorities manning a roadblock in Narathiwat during an inspection. — Bernama GEORGE TOWN: Thailand remains a top holiday destination for Malaysians despite the country's latest political crisis. The suspension of Thai Prime Minister Paetongtarn Shinawatra coupled with ongoing violence in some of the country's southern provinces and a surge in respiratory illnesses are unlikely to deter Malaysians. Haadyai, a city close to the border with Kedah, remains a favourite for a quick break. Executive Erma Idayu Mohd Yusop, 38, is planning a weekend trip there with her family despite the country's troubles. 'I'm not worried at all. In fact, we're heading to Haadyai this weekend for a short family vacation,' she said. She said she would avoid the so-called Deep South – the provinces of Pattani, Yala, Narathiwat and parts of Songkhla – where violence linked to a decades-long insurgency has increased. 'Of course we won't go to risky places. I'll also wear a face mask and stay away from crowded spots, especially with my elderly parents and kids,' she said. On July 1, Thai Department of Disease Control spokesperson Dr Jurai Wongsawat warned of increased risks for eight diseases including Covid-19, influenza, dengue fever and measles as the country heads into its rainy season. Dr Jurai also urged the public to take precautions in light of the rising cases of Covid-19 and the threat of bird flu, which has recently emerged in Cambodia. Civil servant Edward Lee, 45, is also heading north. 'I feel the western coast of southern Thailand is still relatively safe. The issues seem to be concentrated in the southernmost areas,' he said. He has visited Haadyai before and plans to go again this week. 'As long as we stay cautious and avoid troubled zones, there shouldn't be a problem. Life has to go on,' he said. He said many Malaysians are still drawn to Thailand for its food and shopping. A travel agency said demand for trips to Haadyai had spiked. 'All seats for this weekend are fully booked,' said a staff member. 'Families, couples and even groups of friends are going. Everyone wants a short getaway.' Insurance and travel agent Mohd Hazrizal Abdul Halim, 26, whose shop is near Bukit Kayu Hitam, said he had seen more customers than usual. The surge in Malaysian visitors to Thailand are occurring even as the past three months have seen more than 10 violent incidents in the southern provinces which have claimed the lives of children, security personnel and village defence volunteers. 'Sales went up about 20% for this weekend,' said Mohd Hazrizal, adding that he expects to see more business as school holidays approach. 'Malaysians just love going to Thailand,' he added.

No link between Covid-19 vaccines and sudden deaths
Many sudden deaths have been reported among youth in India, with widespread speculation that these were due to Covid-19 vaccines. 02 Jul 2025 03:23pm Many sudden deaths have been reported among youth in India, with widespread speculation that these were due to Covid-19 vaccines. - 123RF photo NEW DELHI - There is no link between Covid-19 vaccination and unexplained sudden deaths in India, the Health Ministry said on Wednesday. Many sudden deaths have been reported among youth in India, with widespread speculation that these were due to Covid-19 vaccines. "The matter of sudden unexplained deaths has been investigated through several agencies in the country. These studies have conclusively established that there is no direct link between Covid-19 vaccination and the reports of sudden deaths in the country," the Indian Health Ministry said in a statement. It said the studies carried out by the Indian Council of Medical Research (ICMR) and National Centre for Disease Control (NCDC) on the 18 to 45 age group found that Covid-19 vaccines in India are safe. "Sudden cardiac deaths can result from a wide range of factors, including genetics, lifestyle, pre-existing conditions, and post-Covid complications," the ministry said. The ministry said "speculative claims" linking sudden deaths to vaccination may undermine public trust in vaccines. - BERNAMA More Like This
