Singapore’s Ministry of Health is now on a propaganda drive trying to mislead Singaporeans into thinking that asymptomatic carriers of COVID-19 are not infectious.
When the MOH reported 7 so-called community cases on Wednesday (Jun 10), it highlighted that 5 of them are asymptomatic. Commentators on state media Facebook pages misinterpreted the term and ignorantly expressed relief that these cases are asymptomatic.
The term “asymptomatic” however only means that no symptoms were shown. Around the world, asymptomatic spread has been proven to be one of the primary causes in enclosed spaces like trains and buses in public transport.
Asymptomatic cases are hard to detect, and it does not mean they will not show symptoms later. In fact, most asymptomatic cases do show symptoms later as the virus slowly work its way around in their body. Some has displayed symptoms as late as 19 days later in a recent imported case in Shanghai from Singapore:
“China reported its only imported case on Tuesday, May 26, from Singapore. A China national who worked in Singapore arrived at the Shanghai Pudong International Airport on May 7, showed infection when he went through a CT scan and tested positive for a serum antibody test. He however tested negative with the standard nucleic acid test.
The China authorities did not take any chances and quarantined him, where he subsequently showed symptoms and tested positive on May 25.”
Being asymptomatic does not mean you are well, or immune to the virus. Your lungs could be showing dark spots in a scan and blood vessels and arteries could be clotting up due to the virus.
The MOH do know asymptomatic cases are infectious, otherwise they will not be putting the close contacts of asymptomatic carriers on quarantine.
