Omicron Peaking in Weeks, Not Months: Johns Hopkins

The transcript discusses the Omicron variant's rapid spread and its impact on hospitalizations. It compares Omicron's virulence to Delta and influenza, highlighting its high transmissibility. The contagious period is typically around five days, with guidelines suggesting antigen tests for precision. Strategies for workplaces include daily antigen testing and flexible isolation periods. The transcript advises against using PCR tests for screening due to prolonged positivity, recommending antigen tests instead.

What is the expected timeline for the Omicron variant to peak and decline?

• Two to three months

• Two to three weeks

• Four to six weeks

• One to two months

How does the virulence of Omicron compare to Delta and influenza?

• Omicron is equally virulent as Delta and influenza

• Omicron is more virulent than Delta but less than influenza

• Omicron is less virulent than both Delta and influenza

• Omicron is about half as virulent as Delta but more than influenza

What is the average contagious period for most people with Omicron?

• 5-5.5 days

• 2-3 days

• 7-10 days

• 10-12 days

Why are antigen tests preferred over PCR tests for determining contagiousness?

• PCR tests can show positive results for up to 12 weeks

• PCR tests are faster

• Antigen tests are more accurate

• Antigen tests are cheaper

What should workplaces focus on to prevent transmission while reopening?

• Daily antigen testing and a five-day isolation period

• Zero tolerance for cases

• Daily PCR testing

• Weekly antigen testing

What is a major drawback of using PCR tests for screening asymptomatic individuals?

• They are too expensive

• They provide results too quickly

• They can detect non-contagious viral debris

• They are not widely available

What is a sustainable approach for workplaces to manage COVID-19 cases?

• Shutting down at every case

• Using antigen tests and accepting some cases

• Relying solely on vaccination

• Implementing strict lockdowns
