Coronavirus vaccination is now a race against the spread of the Delta variety, which is two times more contagious than earlier strains. Delta is responsible for nearly all new cases, with daily averages of far over 100,000 in the United States. Despite the fact that millions of individuals are still getting vaccinated, millions more are still afraid or doubtful.


Medical experts believe that this is now predominantly a pandemic of the unvaccinated. The vaccines, on the other hand, do not provide complete protection against the Delta form. Cases of breakthrough are possible. The immunizations offer protection against Delta infection ranging from 39% to 96 percent.


Dr. Amira Roess is a professor of Global Health and Epidemiology at George Mason University's College of Health and Services and an infectious disease expert. She gave both vaccinated and unvaccinated people information on how to tell if they have the Delta variation. Read on to learn more, and don't miss these Sure Signs You May Have Already Had COVID to protect your health and the health of others.


You were most likely infected with the Delta form if you were diagnosed with COVID-19 this year. It is a good idea to get tested if you are experiencing symptoms and have been in close touch with someone who has been infected. Vaccinated people usually have milder symptoms than those who have not been vaccinated. Cough, fever, headache, and loss of taste or smell are common symptoms, which are similar to those of a moderate cold.


Symptoms that aren't as severe don't always necessitate hospitalization. Unvaccinated people account for the majority of COVID hospitalizations. When breakthrough infections occur, they are often asymptomatic or have very minor symptoms.

Signs of Infection for the Unvaccinated 

95% of new cases come from the unvaccinated population. Unvaccinated individuals may experience cough, fever, chills, muscle aches, headaches, loss of taste or smell, and many other symptoms. They may endure these symptoms for much longer than those who are vaccinated, which could result in hospitalization.


Preliminary data analysis suggests that among unvaccinated individuals, the Delta variant may cause more severe symptoms than the Alpha variant. We are waiting for much-needed data to help answer this question. We do know that the Delta variant infects more individuals.


There is also compelling evidence of a longer duration of infectiousness among the unvaccinated compared to the first strain of COVID-19. Individuals infected with the Delta variant can infect about twice as many individuals as we had observed in people infected with the Alpha variant.

Get Vaccinated

These vaccines protect people from serious illness and hospitalization by up to 90%. To limit the spread, wear an N95 mask or facial covering. Social distancing while indoors and participating in group activities outside as much as possible is also crucial in stopping the proliferation of this highly contagious variant. 

What to Do If You Think You're Infected

Says the CDC:

"COVID-19 affects different people in different ways. Infected people have had a wide range of symptoms reported – from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

Fever or chills
Shortness of breath or difficulty breathing
Muscle or body aches
New loss of taste or smell
Sore throat
Congestion or runny nose
Nausea or vomiting
Look for emergency warning signs for COVID-19. If someone is showing any of these signs, seek emergency medical care immediately:

Trouble breathing
Persistent pain or pressure in the chest
New confusion
Inability to wake or stay awake
Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone
Call your medical provider for any other symptoms that are severe or concerning to you.

How to Stay Safe Out There

Follow the public health fundamentals and help end this pandemic, no matter where you live—get vaccinated ASAP; if you live in an area with low vaccination rates, wear an N95 face mask, don't travel, social distance, avoid large crowds, don't go indoors with people you're not sheltering with (especially in bars).
