SINGAPORE - A new study by the National Centre for Infectious Diseases has found that the ability of Covid-19 patients to contaminate their environment with the coronavirus peaks during the first week of their illness, but falls significantly afterwards.
But the study's principal investigator, Dr Kalisvar Marimuthu, a senior consultant at NCID, said this finding alone is insufficient to prove that Sars-CoV-2 is airborne"as the viability of the virus in the air will need to be proven". They found that surface contamination was significantly higher in the rooms of patients in their first week of illness, regardless of whether they showed symptoms.
Meanwhile, Sars-CoV-2 particles were found in air samples of two of the three rooms. Both the patients in these rooms had been ill for five days, and had high viral loads.
