Karnataka government releases a new circular to diagnose ‘Covid-19 probable’ cases. As reported by Deccan Herald, government recognised a new category of patients with “Covid-19 Like Syndrome”, who test negative for Covid-19 in RT-PCR but are later found to have serious Covid-like illness through high-resolution CT (HRCT) scan.

It suggested a four-pronged approach to identify such patients such as Clinical, radiological, blood investigations and nasal and throat swab.

It is said that the government will employ Covid-19 Reporting And Data (CORAD), a new method to assess the risk factor of such patients.

CORAD score is a CT scan-based system that is used to assess the suspicion of pulmonary involvement in Covid-19.
