In comparison to last year, people are more relying on the expensive scan this year.

While addressing a press conference, Randeep Guleria said, “There have been studies which show that around 30-40 percent of people who are asymptomatic but are Covid positive and got a CT scan done, they also had patches which ended without any treatment.”

He further said that CT scans and markers are being misused. Guleria said that there is no use of the CT scan when a patient is having mild symptoms as it will not detect COVID.

The AIIMS director suggested going for an X-ray first, if necessary. He also said that a patient should undergo a CT scan on the advice of a doctor only.

He also said that asymptomatic patients with normal oxygen saturation should not go for CT scans.

Dr. Randeep Guleria advised people to take both doses of the vaccine. He also said that if a patient has contracted COVID after the first dose then he or she should wait for 2 to 8 weeks before taking the second dose of the vaccine. He recommended that if a person is having mild symptoms, fever, or cold, he should not get vaccinated.

“You can get inoculated after recovery so that next time, the vaccine will act as a protective shield in your body to fight the virus,” Dr. Guleria said.
