Pay attention to the rollout of antibody tests. When available, those will tell you whether your blood contains immunoglobulins targeting the virus, and thus whether you've had it. If you have, consider also paying attention to news about serum transfusion projects in your area. That's a process by which an immune person donates antibody-containing plasma, which is then transfused into patients with active disease or at-risk people to supplement their immune system with "targeting data" for the disease. It can significantly improve people's chances, and is one of the longer-term (and admittedly less likely, since no one is really certain yet whether or how well it'll work) possibilities I'm looking at for how to effectively volunteer as an immune person once my own COVID-19 case resolves.
