The latest case from Taiwan is kind of scary - read for yourselves:
“On May 7, the Central Epidemic Command Center (CECC) announced one new confirmed imported case of coronavirus disease 2019 (COVID-19) in Taiwan. Case #440 is an over 20-year-old female who visited Qatar for work in the second half of February. She was diagnosed with COVID-19 on March 10 and received medical treatment in Qatar. After being treated, she was tested negative for COVID-19 twice and returned to her dormitory on April 8.
The CECC reported that the case didn’t show any symptoms when she returned to Taiwan on May 3. She voluntarily reported her previous diagnosis of COVID-19 to quarantine officers at the airport upon arrival. Although she was tested negative for COVID-19 on May 4, she had diarrhea the same day. Health agencies then arranged her medical care and COVID-19 testing on May 5. Infection with COVID-19 was laboratory-confirmed in the case on May 7. The CECC is investigating passengers on the same flight as the case to identify contacts of the case.”
