Dr. Ramzi Yacoub (PharmD), SingleCare Chief Pharmacy Officer says, "If you're experiencing brain fog and the inability to concentrate, it may be a sign you already had COVID. Cognitive slowing and mood problems after a person is infected with the coronavirus are much more prevalent than other viral infections."


Bad Cold

According to Dr. Yacoub, "While it's not uncommon to get a cold every winter, if it was around for 2 weeks or longer it might have been COVID. While a cold typically lasts only a few days, COVID cold-like symptoms can manifest for much longer, causing a fever and making it hard to breathe."


Tiredness / Fatigue

Dr. Kunal Gurav, M.D., FACC, MBA, ChenMed Medical Director of Cardiology and Regional Chief Clinical Officer for Dedicated Senior Medical Centers in Missouri and Tennessee explains, "Antibody tests are unreliable and there's no clear data about what level of antibodies are considered "protective". The best way is to do an antigen test or RT-PCR when you are exposed or symptomatic. Vaccines offer more reliable protection than natural infection."

Why COVID is Likely to Surge Again

Erica Susky, an Infection Control Practitioner (ICP) in hospital epidemiology states "COVID-19 has so far occurred in surges either when a newer Variant of Concern (VOC) emerged or when public health restrictions eased and more people congregated. It is hard to predict when and if a new VOC will occur but viruses, as all living things, will evolve and another variant will likely occur. What will likely imminently drive another increase in COVID-19 cases is a relaxing of public health restrictions. As more people go without masks and congregate, there are more opportunities for SARS-CoV-2 to spread from person to person."
