Little is known about this issue and It's unclear whether people who recover from COVID-19 will be immune to reinfection from the coronavirus and, if so, how long that immunity will last. My own guessing is either completely become immuned or have a milder form of a disease if they do get reinfected later.

We do not know as of yet, there has been a few reports on people getting 'reinfected' but it is unclear if this was a new infection or if the patient failed to fully clear the original infection that came back into play.

Immunisation times are also an unknown factor and will have to monitor ex-patients over time to answer that

For your own wellbeing and that of others the best practice I can think of is assume you are not immune after you clear an infection. This will help with two things 1) making sure you reduce risk to yourself from getting it again if you truly dont have a good immune response to the virus and 2) If you have immunity to the stage where you are non-symptomatic but may become a carrier and portentially seed other infections.

Again I am just speculating, we dont have accurate information on any of this yet so practice social distancing and good hand hygiene for sure

Ebot Walter Ojong this case is rare, the virus is quite new. In limited cases in china, recorded infection of people recently was recovered from coronavirus. But till now, no one knows exactly if those people suffering from new coronavirus series or they are not really recovered in the first infection.

Yes

Ebot Walter Ojong < How Long is a patient immuned after recovering fromCOVID-19? >

We always wander how long antibody can protect us, especially the antibody induced from SARA-CoV-2. Although we don't have the answer for SARS-CoV-2 yet, we can learn some lectures from SARS-CoV (or simply SARS), a cousin of SARS-CoV-2. Attached is a chart showing us when the antibody is produced, and how long it can protect us. Day-7, a detectable amount of antibody is observed. Antibody provides about 3~4-years of protection (in the chart, M: month, Y: year). Paper is available for download online ([1]; free access).

RNA-based positive RT-PCR swab tests on throat or fecal swabs in a recovered patient has not been clearly associated with worsening of symptoms, lab or radiological investigations and contagiousness of such a patient

It is not yet established that patients who are declared recovered from COVID-19 on the basis of two NEGATIVE RT-PCR tests for SARS-CoV-19 had actually recovered due to laboratory error of testing kits or the the positivity indicated a carrier state, as none of these reports indicated any worsening of clinical condition of the patient based on symptoms, CT-scan or other parameters (1). We have seen many patients with COVID-19 who despite making a clinical recovery are often having positive reports based on the RT-PCR results up to 35 days after initial diagnosis (2). There has been talk of viral RNA belong to dead virus (viral litter, debris) as the explanation for positive RNA-based PCR tests, as this test does not establish the presence of live virus.

Important point is that there is a disconnect between positive tests and the clinical condition of the such COVID-19 patients. If you follow up such patients, none of the patients had adverse outcome.

Duration of immunity after recovery from COVID-19 is not established, but if we go with immunity after SARS-CoV-1 (cause of SARS), immunity may be anything between 1-3 years.

Yes, it is possible to get COVID-19 twice, as the acquired immunity is short lasting. COVID-19 immunity can last 6 to 8 months after infection.
