First Person to Be Reinfected with COVID-19 Recorded in Hong Kong


Can I get Coronavirus more than once? That is a common question.  Yes.  This story from Hong Kong elaborates on your question.   

In many ways Coronavirus acts like most viruses. It's the mechanism of action however is quite different from an ordinary "respiratory virus'. It is not a true respiratory virus although it has been channeled into the 'influenza' family.

Like other viruses, it takes the immune system about 4 weeks to produce measurable antibodies, protective or not. During this incubation period, the immune system is triggered and specific T cells (specialized lymphocytes) are released from lymph nodes, spleen, and bone marrow.  T cells have a memory from previous foreign antibodies and the new agent is sensed. The immune factory begins to 'pump out" the correct T cells to attack foreign antibodies. In HIV the virus attacked the CD4 T-cells destroying it's the capability to multiply and produce anti-HIV antibodies.


It does not appear that Coronavirus attacks T-cells.

First proven case of reinfection

The World Health Organization (WHO) stated that there's no immediate need to jump to any conclusions on the basis of one patient, per the BBC's report.

Hong Kong scientists observing the patient in question have noted that the two strains of the virus are different.

The report on the matter, written by Hong Kong University scientists and shared on Twitter, explained how the man in his thirties spent 14 days in hospital when he was first diagnosed with COVID-19 where he recovered. Following this, during a screening at the airport, he tested positive once again for the virus, despite being asymptomatic.
