Lung ultrasound screenings have identified novel coronavirus infections in people who were asymptomatic and tested negative for the virus, according to reporting in The Times of Israel.

The officials were quoted as saying the small, portable ultrasound kit called “Focus” had already helped discover several asymptomatic patients, and that several who tested negative were re-diagnosed with COVID-19.

One of them is a special education teacher who had caught the virus but was no longer showing symptoms and was cleared by a testing lab as recovered. Her test, taken out of caution before returning to work, revealed she still had the virus, according to Dr. Eran Shankar, who manages the Bnei Brak clinic.

The machine is currently in use only in virus hotspots such as the ultra-Orthodox cities of Bnei Brak and Elad, and will soon be available throughout the country, according to the report.
