You can get COVID more than once, and have symptoms over a long period of time,. If you get COVID again and have COVID symptoms while you are sick, that is COVID symptoms. But if you partly recover from an infection and find that you still have lingering symptoms, or even new symptoms 4 weeks later, that may be Long COVID
Every time you get a COVID infection, you could also get Long COVID. The best way to prevent getting long COVID is to not get COVID in the first place. The same advice that you have heard for three years now still applies - get vaccinated, be aware of how much COVID is in the community now, and consider masking in crowded indoor spaces.
But did you know that if you do catch COVID (let’s face it, most of us have) Vaccination helps to prevent long COVID! So, even when vaccines become less effective at preventing COVID infections, they continue to reduce the risk that you will get long COVID and reduce the risk that you will DIE!
