Keeping living spaces clean and sanitary is an important part of preventing the spread of COVID-19 alongside diligent hand washing and using sanitizer, Taichung Veterans General Hospital physician Chen Po-yan (陳伯彥) said on Monday.
SARS-CoV-2, the virus that causes COVID-19, is spread through respiratory droplets or through contact with a contaminated surface, Chen said.
Due to the risk of infection through contact with surfaces, hand washing immediately after the removal of outdoor clothing and footwear is important to avoid the risk of spreading the virus in the home, he said.

People are advised to maintain good personal hygiene, and avoid sharing dishes and utensils, as well as regularly cleaning and sanitizing shared areas of the home, he said.
A 75 percent alcohol solution or chlorine solution can sanitize surfaces and kill SARS-CoV-2, but these materials are ineffective against noroviruses and enteroviruses, he said.
Therefore, bleach should be used to clean surfaces, he said, adding that it is especially important to sanitize surfaces that are frequently touched, such as doorknobs, toilet handles and faucets.
A 75 percent alcohol solution renders SARS-CoV-2 cells inactive, Tainan Municipal An-Nan Hospital physician Chen Hung-yu (陳泓毓) said.
However, because bleach and other chlorine solutions contain hypochlorous acid — which destroys protein structures — they can inhibit the virus’ activity, Chen Hung-yu said.
Alcohol-based sanitizers are generally more convenient to carry outside — particularly as they evaporate quickly — and so are best used for sanitizing hands and smaller items, he said.
However, soap and warm water should be used to clean blood or other body fluids from the skin, as alcohol solution is not as effective, he said.
Bleach is best for disinfecting rooms, with a ratio of 500 parts per million (ppm) sufficient for most surfaces, he said, adding that 5,000ppm could be used on particularly dirty surfaces or where blood was present.
Food-grade chlorine (sodium hypochlorite) can disinfect fresh produce, but the ratio should not exceed 100ppm and the chlorine should be washed away before consumption, he said.
Chlorine solutions should be used within 24 hours after mixing, and should be kept away from direct sunlight and high heat, he said.
As bleach and other chlorine solutions can cause skin and respiratory system reactions, contact should be kept to a minimum and avoided entirely for people with allergies, Chen Hung-yu said, adding that the solutions should be applied with a cloth, not sprayed.
People can fight viruses by supporting their immune system through proper sleep, adequate exercise and a balanced diet, he said.
A small number of Taiwanese this year lost their citizenship rights after traveling in China and obtaining a one-time Chinese passport to cross the border into Russia, a source said today. The people signed up through Chinese travel agencies for tours of neighboring Russia with companies claiming they could obtain Russian visas and fast-track border clearance, the source said on condition of anonymity. The travelers were actually issued one-time-use Chinese passports, they said. Taiwanese are prohibited from holding a Chinese passport or household registration. If found to have a Chinese ID, they may lose their resident status under Article 9-1
Taiwanese were praised for their composure after a video filmed by Taiwanese tourists capturing the moment a magnitude 7.5 earthquake struck Japan’s Aomori Prefecture went viral on social media. The video shows a hotel room shaking violently amid Monday’s quake, with objects falling to the ground. Two Taiwanese began filming with their mobile phones, while two others held the sides of a TV to prevent it from falling. When the shaking stopped, the pair calmly took down the TV and laid it flat on a tatami mat, the video shows. The video also captured the group talking about the safety of their companions bathing
PROBLEMATIC APP: Citing more than 1,000 fraud cases, the government is taking the app down for a year, but opposition voices are calling it censorship Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) yesterday decried a government plan to suspend access to Chinese social media platform Xiaohongshu (小紅書) for one year as censorship, while the Presidential Office backed the plan. The Ministry of the Interior on Thursday cited security risks and accusations that the Instagram-like app, known as Rednote in English, had figured in more than 1,700 fraud cases since last year. The company, which has about 3 million users in Taiwan, has not yet responded to requests for comment. “Many people online are already asking ‘How to climb over the firewall to access Xiaohongshu,’” Cheng posted on
A classified Pentagon-produced, multiyear assessment — the Overmatch brief — highlighted unreported Chinese capabilities to destroy US military assets and identified US supply chain choke points, painting a disturbing picture of waning US military might, a New York Times editorial published on Monday said. US Secretary of Defense Pete Hegseth’s comments in November last year that “we lose every time” in Pentagon-conducted war games pitting the US against China further highlighted the uncertainty about the US’ capability to intervene in the event of a Chinese invasion of Taiwan. “It shows the Pentagon’s overreliance on expensive, vulnerable weapons as adversaries field cheap, technologically
