Covid-19 increased by 17.6%, time to mask up again , say experts

Better safe than sorry: people who had not completed their vaccination, either with a booster or prime vaccinations, should be masked when in public, say health experts.  

 


PETALING JAYA: With the rise in Covid-19 cases of late and more Hari Raya social gatherings expected, public health experts are suggesting that face masks be worn in public.

High risks individuals, such as the elderly, the obese, those with high comorbidities and immunocompromised issues such as diabetes and cancer, are among those who are at risk of an infection or re-infection.

“As such, they are highly encouraged to wear masks,” said Universiti Kebangsaan Malaysia public health expert Prof Dr Sharifa Ezat Wan Puteh.

Likewise, she said people who had not completed their vaccination, either with a booster or prime vaccinations, should be masked when in public.

“It is better to be safe than sorry. Get yourself vaccinated, including the boosters. If you’re at high risk, wear a mask in public areas where there are many people who may be transmitting or carrying the virus,” she said.

She also spoke about an upsurge in cases at certain schools, so students who are at risk should mask up.

“The increase in Covid-19 cases is expected, due to a few highly transmissible Omicron strains, unmasking and many of us moving freely across states and in our workplaces.

“However, the main issue is whether the rise in cases will lead to hospitalisation or even deaths,” she said.

A Health Ministry statement on April 13 said that Covid-19 hospital admission had increased by 17.6% in the beginning of April compared to the previous month.

Health Minister Dr Zaliha Mustafa said 63.8% involved patients aged 60 and above, while 90.7% were among those with comorbidities.

Most of them had mild symptoms and deaths among patients who were not vaccinated was six times higher than those who received a single dose, she added.

Prof Dr Moy Foong Ming of Universiti Malaya’s Department of Social and Preventive Medicine suggested that the ministry should intensify its public messages on the importance of masking and encourage the people to do so during the surge in cases.

As for Covid-19 infections in schools, she said that parents should not send their children, who showed symptoms, to school.

“The school management should be alert to the health status of their staff and students. Take appropriate action when any of the staff or students are unwell,” she said.

However, experts like Dr Moy are of the view that it is not necessary to make it mandatory for people to wear mask.

She said that making masks mandatory was no longer feasible as the country was in the transition to the endemic phase.

“We are to co-exist with the virus. The public should have internalised the preventive measures and carry them out voluntarily when there is a surge in cases,” she said.

“If masking is made compulsory, then there should be punitive measures on those who don’t comply.

“This will not educate the public but rather they mask up because of fear of possible punitive action taken against them.”

Malaysian Public Health Physicians Association president Datuk Dr Zainal Ariffin Omar also said that masking should not be made mandatory but strongly encouraged.

“I think the public will not be too receptive if mandatory masking and added regulations are imposed,” he said.

He said that people should be encouraged to self-test and self-quarantine should they show symptoms.

Universiti Putra Malaysia medical epidemiologist Assoc Prof Dr Malina Osman said current measures could be maintained but those who tested positive must wear a mask to protect others.

“Those who are sick should stay at home, and be quarantined. If they need to be in public, wearing a mask is a must,” she said.

She added that the decision to make masking compulsory should only be made when the rise of Covid-19 cases posed a threat to the country’s healthcare system.

“Currently, there is no such indication, so there is no urgent need to make it compulsory,” she said.

However, she said there was a need to enhance public awareness, so that the people could be responsible to each other.

Dr Malina said the rise in cases was most likely due to the current strain being highly infectious.

“In general, we have to be more cautious. As such, people are encouraged to mask up in public, be mindful of hand hygiene and cough etiquette,” she said.

China Makes the First Quantum Chip "Refrigerator", China's Innovations That Have Sparked International Interest

 

The Chinese manufacturer Benyuan Quantum has built the first quantum chip production line in China, laying the foundation for the mass production of quantum chips in China.

Following the quantum chip production line, China has made another breakthrough in quantum technology and created a "quantum chip refrigerator".

China's first "refrigerator for quantum chips" has been put into use to maintain a stable environment and enable the smooth operation of quantum chips, scientists revealed on Wednesday.

The "refrigerator," actually a high-vacuum box, has three cavities for storage and each can be controlled separately.

A smart system monitors the cavities in real time to maintain a high-vacuum state, according to a statement by the developer of the device, Origin Quantum Computing Technology Co, which is based in East China's Anhui Province.

A human-computer interaction function guarantees automated operation of the device, read the statement.

The Global Times learned from Origin Quantum that compared with a classic integrated circuit, a quantum chip requires a more complicated manufacturing process. Temperatures and conditions in the chip's environment, such as noise, vibration, electromagnetic waves and even super-small particles, would have an impact on the quantum chip.

If the strict environmental conditions are not maintained, superconducting materials can easily react chemically with oxygen and water vapor in the air, absorbing various impurities. As a result, the key components of the chip may fail to burn in and would not function correctly.

Scientists have compared the burn-in process with "food going bad" in the air and dubbed the high-vacuum box as a "refrigerator for quantum chips."

Quantum chips are the "brains" of quantum computers, which use quantum mechanics to perform certain computations far more efficiently than a regular computer.

Although the general public is mostly unfamiliar with quantum computers and their capabilities, the Spring Festival box office hit The Wandering Earth II offered a fictional opportunity for people to comprehend the immense computing power these machines possess.

Regulating short-term stays in Penang, such as Airbnb Hosts, homestays

 Stating it clearly: A banner is hung at the entrance stating the ban on short-term homestays at one of the apartments in Gelugor, Penang.ZHAFARAN NASIB/The Star

 GEORGE TOWN: Residential property investors hoping to make a killing from the short-term stay business are likely to find it an uphill task with the new regulations in place.

State local government, housing, town and country planning committee chairman Jagdeep Singh Deo said other residents would now need to give their consent to units being used for short-term stays.

“I do not think it will be easy for one to gain approval from all other residents in a high-rise building. Even then, there are limitations.

“They will need to have a general meeting and seek approval.”

Jagdeep said the Penang government has two guidelines for short-term stays – one for high-rises and the other for landed properties.

“Both guidelines were approved by the state executive council on March 8 and will now be enforced.

“We have received many complaints regarding short-term stays. Such practices disrupt the lives of other residents,” he said.

“We formulated these guidelines not to deny property owners the right to rent them out, but to regulate short-term stays.”

Jagdeep said that for stratified projects classified as residential, one must first obtain approval from the joint management body (JMB) or management corporation (MC) through an AGM, on top of complying with other terms in the guidelines.

“Serviced apartments classified as being in a commercial zone must comply as well.

“If approval is given (for the residential or commercial properties), the short-term stay must not be for more than three days per reservation.

“On top of that, each unit must not be booked for more than 180 days in a year,” he added.

Jagdeep said many residential high-rise buildings had put up banners clearly stating that short-term stays are not allowed.

“It is clear that it will be difficult for people to convince many JMBs or MCs to allow them to use their units in that way,” he said.

Jagdeep said hotels in Penang are well equipped to cater to the needs of tourists.

“We must be fair to the people and the tourism sector,” he said.

Malaysian Association of Hotels (MAH) national vice-president Datuk Khoo Boo Lim said the guidelines would help hotels.

“We are not able to stop them from operating but with rules in place, there will be no abuse.

“They will need to follow guidelines and only those who comply will be allowed to operate.

“This will definitely help hotels as the number of short-term stay units will drop,” he said.

However, the Asia Travel Technology Industry Association (Attia) urged the state government to reconsider its decision to enforce the new guidelines.

It said the new guidelines are “untested, disproportionate, and complicated”.

“The Penang Government should have considered co-regulation and self-regulation approaches, such as voluntary code-of-conduct style frameworks, which have successfully reduced noise and nuisance issues in short-term stay homes without imposing onerous requirements,” the association said in a recent statement.

Attia said most short-term stay hosts are individuals and not companies, and such individuals could be “pushed out from participating in the lucrative sharing economy”.

The association said short-term stays complement hotels by catering to “price-sensitive digital nomads and youth travellers”, and also families wanting to rent a whole house for their holidays.

Attia is an NGO representing global businesses dealing in travel and tourism in Asia Pacific, including online room and flight booking portals.
