After recovering from a positive COVID-19 test, can you still transmit it to family members?

Introduction
If the recovery period from a positive coronavirus test was relatively short, there may still be a small amount of residual virus in the body, which could be infectious, so there is a certain chance of transmitting it to family members. However, if sufficient time has passed and nucleic acid testing or antigen testing for the novel coronavirus shows negative results, this generally indicates that the virus has cleared from the body, and in such cases, transmission to family members is unlikely.

“Post-recovery from a positive COVID-19 test” generally refers to the period after recovering from a confirmed SARS-CoV-2 infection. Whether an individual can transmit the virus to family members depends on specific circumstances. The detailed analysis is as follows:

1. Yes, transmission is possible

If recovery from a positive SARS-CoV-2 test was recent, there may still be small amounts of residual virus in the body that remain infectious, meaning there is a certain probability of transmitting the virus to family members.

2. No, transmission is unlikely

If sufficient time has passed since recovery and subsequent nucleic acid testing (such as PCR) or SARS-CoV-2 antigen testing yields negative results, this generally indicates that the virus is no longer present in the body, making transmission to family members unlikely.

It is recommended that individuals maintain a balanced diet, regular sleep patterns, a positive mood, and engage in appropriate physical exercise in daily life. These habits can help strengthen the immune system and reduce the risk of contracting SARS-CoV-2 infection.
