- Ushio's Care222TM krypton-chloride excimer lamp was used during the tests.
- A 100 microliter solution containing the virus (ca. 5 × 106 TCID50/mL) was spread onto a 9-centimeter sterile polystyrene plate.
- The in vitro experiment results revealed that 99.7% of the SARS-CoV-2 viral culture was killed after a 30-second exposure to 222 nm UVC irradiation at 0.1 mW/cm2.

Since the study examined the in vitro efficacy, researchers suggested further evaluation of 222 nm UVC irradiation's safety in killing SARS-CoV-2 viruses in real-world surfaces.

Role of Unconventional T Cells in Severe COVID-19 Patients
Changes in unconventional T cells can predict the disease outcome in severe COVID-19 patients. These changes can be observed by monitoring the activity of these cells in the blood of patients.

How to Deal With Dengue During the COVID-19 Pandemic?
The overlapping symptoms of dengue and COVID-19 infection makes it difficult to distinguish between the two. Besides, a lack of a vaccine or specific antiviral treatment for both diseases makes dengue a double whammy during the COVID-19 pandemic.

Stroke Scans Reveal COVID-19 Infection
COVID-19 can be diagnosed on the same emergency scans including computed tomography (CT) of the head and neck blood vessels that are intended to diagnose stroke.
