SINGAPORE - The mode of Covid-19 transmission is a subject of intense debate after a 53-year-old cleaner who works at a stay-home notice facility was identified as a possible source of infection that led to the latest community cluster at Westgate and Jem malls in Jurong East.
Infectious diseases expert Paul Tambyah said the cleaner - if infected at her workplace - was unlikely to have direct contact with the stay-home notice visitors, so the virus would have somehow carried itself through the air or via a contaminated surface to get to the cleaner.
There are three main modes of transmission: airborne transmission - where people get infected over long distances by inhaling very fine respiratory droplets carried by the air and aerosolised particles; transmission through contact with droplets; and the touching of contaminated surfaces.
SINGAPORE - Many who survive Covid-19 find themselves confronted with another challenge - recovering from the long Covid , which involves residual symptoms such as fatigue and chest pains weeks and months after infection.
The Straits Times delves into why this happens, how prevalent it is and if vaccination will alleviate any of the lingering symptoms.
Q: What is long Covid and what do we know about it?
A: It is a condition where some people continue to experience Covid-19 symptoms for longer than usual, even after recovering from the virus.
Fatigue, shortness of breath, chest pain, joint aches and brain fog - where one s thinking is sluggish - are some commonly described problems that emerge or linger four weeks or more after an infection.
