Comparing COVID-19 and flu symptoms
COVID-19 vs. flu symptoms: How can you tell the difference?
The flu and COVID-19 are both highly contagious respiratory illnesses, but they’re caused by different viruses.
The flu is caused by influenza viruses – usually Influenza A or Influenza B viruses – which we experience during our annual flu season.
There are a lot of influenza viruses out there – and flu vaccines have been around since the mid-1940s. Each year, specific flu vaccines are recommended to fight the strains of influenza that research indicates will be the most common that season. So, when you make a flu shot appointment, you’ll get the vaccine chosen for the most recent flu season.
COVID-19 is caused by a new coronavirus called SARS-CoV-2. Our bodies had never experienced this type of virus before the beginning of the pandemic – which means our bodies hadn’t had a chance to build antibodies to fight it – and we didn’t have vaccines to help protect us. But now, COVID-19 vaccines are readily available for most people, including kids and teens.
