Listed here are a number of the explanation why coronavirus is extra harmful than the flu — and why further precautions are wanted:
Analysis reveals an individual with the flu infects a mean of about 1.28 different folks.
However an individual with novel coronavirus infects a mean of about 2 to three different folks.
And this coronavirus is so new, it isn’t clear whether or not it will dissipate in summer season, or by how a lot. However the truth that it stored spreading within the Southern Hemisphere throughout its summer season months suggests heat climate will not gradual its unfold.
Coronavirus has killed at a a lot quicker price
From October 2019 to early April 2020, the flu killed an estimated 24,000 to 62,000 folks within the US, in line with the US Facilities for Illness Management and Prevention. These numbers are preliminary, and the CDC mentioned it stopped updating its preliminary estimates for this flu season on April 4.
If 62,000 folks died from the flu between October 1 and April 4, meaning the US had a mean of about 331 flu deaths a day.
In contrast, coronavirus killed greater than 62,850 folks within the US from the primary identified demise in February by way of the top of April.
So from February 6 by way of April 30, a mean of greater than 739 folks died per day from coronavirus within the US.
Coronavirus might be unfold for a lot of days with out signs
With the flu, the incubation interval is comparatively quick. Individuals sometimes begin feeling sick one to 4 days after an infection, with signs usually displaying up inside two days, the CDC says.
Which means individuals who get sick from the flu will know they’re sick pretty quickly and can doubtless keep dwelling, avoiding contact with others.
However the incubation interval with coronavirus is about three to 14 days, and “signs sometimes seem inside 4 or 5 days after publicity,” in line with Harvard Medical College.
“We all know that an individual with COVID-19 could also be contagious 48 to 72 hours earlier than beginning to expertise signs,” Harvard specialists write. “Rising analysis suggests that individuals may very well be most probably to unfold the virus to others through the 48 hours earlier than they begin to expertise signs.”
If true, Harvard mentioned, “this strengthens the case for face masks, bodily distancing, and make contact with tracing, all of which might help scale back the chance that somebody who’s contaminated however not but contagious might unknowingly infect others.”
It is easy for asymptomatic carriers to contaminate others, mentioned Anne Rimoin, an epidemiology professor at UCLA’s College of Public Well being.
“If you converse, generally you will spit a bit of bit,” she mentioned. “You may rub your nostril. You may contact your mouth. You may rub your eyes. And then you definately’ll contact different surfaces, after which you’ll be spreading virus if you’re contaminated and shedding asymptomatically.”
You will get a flu vaccine however not a coronavirus vaccine
Consultants say the variety of flu deaths could possibly be drastically diminished if extra folks bought flu photographs. Even in the event you get a flu vaccine and later catch the flu, the signs are often much less extreme.
But about half of Individuals do not get vaccinated, together with most kids who die from the flu.
