Several safety rule breaches, including not wearing proper protective gear while conducting experiments, led to a researcher working at an Academia Sinica laboratory handling the COVID-19 virus to become infected with the disease, an investigative report showed.
The researcher is a woman in her 20s who worked until early this month in a lab at Academia Sinica’s Genomics Research Center. She began to show symptoms of COVID-19 late last month, and a test she took on Dec. 9 came back positive.
Based on genome sequencing results, the Central Epidemic Command Center (CECC) concluded that the laboratory in Taipei’s Nangang District (南港) where she worked was the origin of the infection, which raised questions about whether current safety protocols were adequate in preventing potential transmission and whether the laboratory had breached any of the protocols in place.

In the wake of the incident, Academia Sinica was ordered to conduct an internal investigation, and a 28-page report on its findings was sent to the CECC on Sunday.
According to a summary of the report released by the CECC on Monday, Academia Sinica identified three reasons that the researcher had been exposed to the virus, based on interviews with people who worked there, laboratory records and surveillance footage of the lab.
Researchers are only allowed to handle COVID-19 infected mice in biosafety cabinets, but this rule was breached, resulting in several areas in the lab becoming contaminated, the summary said.
The researcher infected with COVID-19 also took off her mask before removing the rest of her protective gear, which was not the correct order of removal.
Moreover, the researcher and her colleagues failed to wear proper protective gear — including N95 masks, two sets of gloves, and safety goggles — while conducting experiments, the summary said.
As a result, the researcher was directly exposed on several occasions to the virus while wearing inadequate protective gear, which could have resulted in her becoming infected with the disease, although she could also have been infected because she had removed her gear in the wrong order, it said.
Academia Sinica said that it would review its supervisory system for its laboratories that handle sensitive materials, and that it would boost training for research personnel.
The CECC plans to meet with an independent investigation committee looking into the incident on Thursday and release its findings, including what punishments are to be handed out, in two weeks, it said.
The laboratory has been temporarily barred from using infectious biological materials and might only resume their use after obtaining approval from the Centers of Disease Control, the CECC said.
None of the infected researcher’s contacts have tested positive for COVID-19, the CECC said.
Eight Chinese naval vessels and 24 military aircraft were detected crossing the median line of the Taiwan Strait between 6am yesterday and 6am today, the Ministry of National Defense said this morning. The aircraft entered Taiwan’s northern, central, southwestern and eastern air defense identification zones, the ministry said. The armed forces responded with mission aircraft, naval vessels and shore-based missile systems to closely monitor the situation, it added. Eight naval vessels, one official ship and 36 aircraft sorties were spotted in total, the ministry said.
INCREASED CAPACITY: The flights on Mondays, Wednesdays, Fridays and Sundays would leave Singapore in the morning and Taipei in the afternoon Singapore Airlines is adding four supplementary flights to Taipei per week until May to meet increased tourist and business travel demand, the carrier said on Friday. The addition would raise the number of weekly flights it operates to Taipei to 18, Singapore Airlines Taiwan general manager Timothy Ouyang (歐陽漢源) said. The airline has recorded a steady rise in tourist and business travel to and from Taipei, and aims to provide more flexible travel arrangements for passengers, said Ouyang, who assumed the post in July last year. From now until Saturday next week, four additional flights would depart from Singapore on Monday, Wednesday, Friday
The Ministry of National Defense yesterday reported the return of large-scale Chinese air force activities after their unexplained absence for more than two weeks, which had prompted speculation regarding Beijing’s motives. China usually sends fighter jets, drones and other military aircraft around the nation on a daily basis. Interruptions to such routine are generally caused by bad weather. The Ministry of National Defense said it had detected 26 Chinese military aircraft in the Taiwan Strait over the previous 24 hours. It last reported that many aircraft on Feb. 25, when it spotted 30 aircraft, saying Beijing was carrying out another “joint combat
The Ministry of Foreign Affairs (MOFA) today said that if South Korea does not reply appropriately to its request to correct Taiwan’s name on its e-Arrival card system before March 31, it would take corresponding measures to alter how South Korea is labeled on the online Taiwan Arrival Card system. South Korea’s e-Arrival card system lists Taiwan as “China (Taiwan)” in the “point of departure” and “next destination” fields. The ministry said that it changed the nationality for South Koreans on Taiwan’s Alien Resident Certificates from “Korea” to “South Korea” on March 1, in a gesture of goodwill and based on the
