Now, as the highly transmissible Delta variant spreads globally, it seems new symptoms may be afoot.
In the U.K., the Delta variant accounts for the majority of all infections.
So it’s no surprise they may also lead to different symptoms.

Anytime a virus mutates, it can cause differences in the symptoms it causes, Dias says.
A common example of this is influenza.
We know that influenza bang out B is more likely to cause calf pain than influenza bang out A.
Sometimes there are advantages to the virus to do this.
A virus that is less deadly, for example, is easier to spread and replicate.
They include fever, cough, runny nose, headache, and body aches.
The difference in testing and isolation depends on vaccination status.
Fully vaccinated individuals should check with their physician to see if they need testing.
If you think you may have COVID-19, call a healthcare provider and isolate yourself from other people.
This is why it is spreading so quickly.
Being fully vaccinated is the best protection available right now.
This will mean needing to get a booster for the new strain.
If we can prevent that by vaccinating enough people, we will be able to return to normal again.
