My son 13 years old, tested positive on 22/4. Does he need to go for second test after completing his 10 days quarantine period? How to make sure that he is not infectious anymore?

Greetings! Thank you for your question.

In order to determine your son’s current condition, we strongly advised your son to do the second test. You may read all the information below for guidelines and reference. Don’t expose your son to the public unless he is no longer infectious. Always follow the SOPs that have been instructed by our government.

We understand your worries especially regarding the close contact to a positive COVID-19 patient. For your information, COVID-19 screening is usually subjected to patients that have experienced an ongoing fever. Although the criteria may change according to the situation, it is best that you seek immediate help from the nearby clinic or hospital as soon as possible. As far as I’m concerned, once your son is considered a close contact to a confirmed positive coronavirus patient, he is required to do COVID-19 screening as well. This can be done as soon as possible.

According to the Ministry of Health, close contact refers to either:

  • Health care-associated exposure, including providing direct care for 2019-nCoV patients, working with health care workers infected with 2019-nCoV, visiting patients or staying in the same close environment of a 2019nCoV patient.
  • Working together in close proximity or sharing the same classroom environment with a with 2019-nCoV patient
  • Traveling together with 2019-nCoV patient in any kind of conveyance
  • Living in the same household as a 2019-nCoV patient

I would also encourage you to answer this quiz on Risk Assessment for COVID-19 to evaluate their health status in regards to this disease. After completing this quiz, you will be classified into several categories. Further instructions will be given at the end of the quiz. Please act accordingly.

For your information, Person Under Surveillance (PUS) means individual who has close contact with a Patient Under Investigation (PUI). However, this applied before a COVID-19 test is performed.

The swab PCR COVID-19 test is the most accurate and reliable test for diagnosing COVID-19. A positive test means a person likely have COVID-19. A negative test means a person probably did not have COVID-19 at the time of the test. Hence, re-test is not required unless certain conditions according to other probabilities.

But if you want to seek a second opinion, you may try to contact the Crisis Preparedness and Response Centre (CPRC). Other than that, do practice good hand hygiene and normalize wearing face mask in public.
