I think it means after you’re okay from being sick, you can still get others sick.
That's exactly what it means.
In a larger context it means actively ill and recovered people can still infect others. I also read that some people become carriers, with no sign of infection. If this thing also stays alive on surfaces up to 4 hours as I've seen before, spreads by aerosols(and it appears to) , it is going to spread and spread and continue to spread. Lets hope they can get a vaccine spun up before it takes root here.
