While there's much talk on 4% mortality from #COVID19, relatively very less is available on rest 96% who resolve as "recovered"
Initially it was thought that like other ARDS viruses it spreads when symptoms arise.
So thermal scans at airport were placed https://jamanetwork.com/journals/jama/fullarticle/2762452

However it soon became clear that virus is transmissible in asymptomatic phase too
We can b similarly wrong in assuming that patients who recovered r "cured"
Qs
1- Some people r getting reinfected
2- Some people get 2 successive -ve tests & after quarantine they again test +ve

3- Antibodies so produced r not known to b protective for long term, if at all.
4- There may b phase of low level of viremia going on after symptomatic improvement, only to again rise to high viral load.
5- This second rise of viral load may b taken (incorrectly) as reinfection

6- We dont know status of viral transmissibility in that seemingly "recovered" phase
7- Vaccine is still at least >1 yr away
8- RNA viruses r prone to continued mutations as they proceed in their infective cycle
9- Antiviral drugs r helping in clearing viral load in patient but

...only long term follow up on "recovered" patients can tell clear picture if virus was indeed cleared of the body or if it results in no further transmissibilty to others
10- Viral genes tend to get bind in human genome for longer association, effects of which r unpredictable

11- It's quite known for viruses to play hide n seek.
Means there's period of viremia where they can b detected & then they get in hiding when they cant b detected, only to reappear later with more aggressive disease like breakdown of immune system & multi-organ failure!

P.S.
12- Mike Ryan, executive director of the @WHO’s health emergencies programme urged people not to assume the epidemic would automatically subside in the summer.
“We have to assume the virus will continue to have the capacity to spread,” he said.

So we have some idea what's long term prognosis of recovered cases.

Will it die down in summers?
Well, virus does spread more effectively in colder climate still it's no guarantee that it wont b as effective in summers. https://ccdd.hsph.harvard.edu/will-covid-19-go-away-on-its-own-in-warmer-weather/
