The top sign that point that you may have had COVID-19

The cold and flu season are here, and it can be very difficult to tell the difference between the symptoms of a mild cold or flu bug and the symptoms of a mild case of COVID-19. These illnesses are all part of the umbrella term coronavirus (via CDC) so there can be some overlap with similar symptoms. If you’re experiencing one or any of these symptoms, we strongly recommend you to stay home and quarantine. No one wants to spread COVID-19 among other people, and no one wants your regular cold either.

But how will you tell if your mild symptoms may have been part of our largest pandemic ever in our time? And what if you had the virus, but were one of the asymptomatic people who don’t know it (via ACP Journals)? A COVID-19 antibody test may provide you with insight, of course, but there are also some other symptoms that might indicate a past infection. 

Loss of taste and smell can persist after COVID-19 infection

Loss of smell is so prevalent with COVID-19 cases that it is experienced by up to 80% of diagnosed patients (via Vanderbilt University Medical Center). For some 25% of patients, this loss of smell and the linked loss of taste are the only symptoms they experience. Loss of taste and smell can be temporary, may linger for as long as 30 days after more aggressive symptoms subside, or in some cases, can be permanent. 

If you have experienced a loss of taste and/or smell, don’t relax too much. While a past infection may provide you some temporary immunity, you are not guaranteed safe from new infection. Recent reports out of Hong Kong and also Reno, Nevada have shown signs that patients may be susceptible to reinfection (via University of Michigan Health). Michigan Medicine’s Adam Lauring, M.D., Ph.D. explains that it’s not unheard of for immunity to fade over time (think of those tetanus booster shots you’ve probably gotten after an injury). But while reinfection may be possible, it doesn’t mean that it’s probable, so don’t stress too much either.

Loss of taste and smell alone isn’t a sure sign of a COVID-19 infection, but if this symptom is combined with other known symptoms like fever or shortness of breath, you should seek the advice of a medical professional. If you think you may currently have signs of the SARS-COV-2 novel coronavirus, you should consult with your local healthcare provider and get tested.
