Researchers examine SARS-CoV-2 infection rates among migrants workers in Singapore

In Singapore, researchers of several health institutions examined the rate of SARS-CoV-2 infection among migrants workers.

In their study, released in JAMA, a near total of 200,000 migrants workers were evaluated, with close to 95 percent having been tested at least once for SARS-CoV-2.

The study took place between March 25th and July 25, 2020.

According to researchers, about 56 percent of the migrant workers tested for the virus had confirmed to be infected.

“There were 24 197 clinical cases (12.2% of all residents; 21.7% of infected) from 42 dormitories and 87 083 subclinical cases (43.9% of all residents; 78.3% of all infected),” the findings read. “Of all clinical cases, 20 cases required ICU admission, with 1 COVID-19–attributable death.”

“The COVID-19 outbreak among Singapore’s migrant workers was characterized by a high prevalence of infection, low morbidity with few ICU admissions, and low mortality. The low case-fatality rate compares favorably with rates reported in other national registries,” researchers wrote in their findings.

The study was authored by Iain Tan, Clive Tan, and Li Yang Hsu, among others.
