As much as we'd all love COVID to go away, the pandemic isn't over by any means. While cases are dropping, experts are predicting another surge and urging people to continue taking measures to protect themselves and others. To date more than 140 million Americans have had COVID-19, the Washington Postreports and if you're asking yourself if you've had the virus, read what experts told Eat This, Not That! Health about the signs to watch out for indicating you may have had COVID. Read on—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.

1. Dry Cough

Dr. Ramzi Yacoub (PharmD), SingleCare Chief Pharmacy Officer shares, "A persistent cough is one of the most common signs you may have had COVID and can linger well beyond the initial infection. If you have a cough that lingers longer than 2-3 days, COVID might be to blame."

2. Heart Palpitations

According to Dr. Yacoub, "For people who have had COVID, lingering heart problems can occur and complicate their recovery. Some of the pulmonary symptoms common in COVID-19 include palpitations, dizziness, chest pain and shortness of breath, since the infection affects the inner surfaces of veins and arteries and can cause blood vessel inflammation, damage to very small vessels and blood clots."

3. Flu-Like Symptoms

Donna Schisler RN, BSN  Clinical Manager withAdvantis Medical says, "Fever or chills, coughing, sore throat, stomach upset and extreme fatigue [are signs of COVID]. You may have one or all of these and they mirror symptoms of influenza. If you notice any of these symptoms, please test yourself or schedule yourself to be tested ASAP. Avoid being around others until you have a negative result and continue to wear a mask around others until symptoms subside."

4. Why COVID is Likely to Surge Again

Dr. Robert Segal, M.D. , Founder and CEO ofLabFinder explains, "COVID-19 is likely to surge again because the virus has already repeatedly mutated into new and more contagious variants. Waning immunity and relaxation of public infection prevention policies also play a role in future expected surges and 'hot spots.' With policies growing more lax, more people gathering indoors and without physical distancing, and fewer people receiving vaccinations and boosters and wearing masks— a growing number of people are becoming vulnerable to infection or re-infection."

5. What People Should Know About COVID Right Now

Dr. Segal states, "People should know right now that it's important to stay diligent. We should continue to follow good infection prevention protocols— like washing our hands thoroughly and often."
