While masks can protect the mouth and nose against COVID-19 infection, they leave the eyes exposed, a doctor said on Sunday, urging people to frequently wash their hands and avoid rubbing their eyes.
The mucous membranes in the eyes could be an entry point for germs or the coronavirus that causes COVID-19, China Medical University Hsinchu Hospital ophthalmology division head Chen Ying-shan (陳瑩山) said.
Some Chinese infected with COVID-19 developed conjunctivitis, with tear and eye discharge samples testing positive for the virus, indicating that there is a risk of contracting the disease through the eyes, he said, citing a study by China’s Zhejiang University.

Mucous membranes in the eye are the only exposed mucous tissues in the human body and could allow the entry of pathogens if there is a tear, Chen said.
The number of children diagnosed with conjunctivitis at a Hsinchu County hospital has risen by up to 40 percent since schools opened late last month, he said.
The increase might be linked to disease transmission at schools or air pollution, Chen said, adding that most parents were not sure whether their child’s condition was caused by an allergic reaction or a bacterial infection.
Symptoms of allergic conjunctivitis in children typically include itching, which leads to frequent eye-rubbing, as well as swelling, redness and excessive discharge, he said.
Pathogens in the discharge could easily spread to the eyelashes and other areas of the face as well as glasses, Chen said.
Washing hands frequently is key to preventing transferring pathogens from the eyes to other surfaces, or vice versa, he said.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said.

Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
