Think you’ve dodged coronavirus bullet? Think again


Imagine that you’ve been close to a person diagnosed with coronavirus COVID-19 and go home without any symptoms, go to bed and wake up without any symptoms. You then go to work and come home without any symptoms.

Returning to work the next day, you tell your work colleagues that you feared you had coronavirus but had experienced nothing unusual.

New research by Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland, US, states that the median incubation period for COVID-19 is just over five days.

“This median time from exposure to onset of symptoms suggests that the 14-day quarantine period used by the US Centers for Disease Control and Prevention for individuals with likely exposure to the coronavirus is a reasonable amount of time to monitor individuals for development of the disease,” John Hopkins Bloomberg School of Public Health stated.

The analysis suggested that about 97.5% of people who develop symptoms of coronavirus infection will do so within 11.5 days of exposure. The researchers estimated that for every 10,000 individuals quarantined for 14 days, only about 101 would develop COVID-19 after being released from quarantine.”

The research is published online today in the journal Annals of Internal Medicine.

Justin Lessler, an author of the study and an associate professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, said symptomatic screening for the virus, such as temperature checks at an airport, may be missing recently infected people.

“If somebody is in their incubation period, that is the window when somebody who’s already been infected can walk into the country and not be detected by symptom-based surveillance” Lessler told CNN.

That could explain why the CDC’s efforts to screen more than 46,000 fliers for “fever, cough, and shortness of breath” have resulted in just one positive coronavirus case, according to the CDC’s most recent screening data, which was released at the end of February.

US President Donald Trump said today he would press lawmakers to enact a payroll tax cut and ensure assistance is available to hourly workers to try to allay economic fears and end the volatility of global stock markets.

Trump said he’d reveal further details of the “very dramatic” steps during a Tuesday afternoon (US time) news conference.

“We are going to be asking tomorrow, we’re seeing the Senate. We’re going to be meeting with House Republicans, Mitch McConnell, everybody discussing a possible payroll tax cut or relief, substantial relief,” said Trump.

“We’re also going to be talking about hourly wage earners getting help so that they can be in a position where they’re not going to ever miss a paycheck.”

In Australia, Prime Minister Scott Morrison is expected to provide a financial stimulus to boost the economy.

“Our objective is this: to keep people in jobs, keep businesses in business and ensure we bounce back stronger on the other side,” Morrison said.

In the UK, Chancellor Rishi Sunak is expected to announce financial handouts for businesses affected by coronavirus in Wednesday’s Budget.
