Thank you for your question.

First and foremost, I understand your concern regarding this current issue of coronavirus since there’s an outbreak. However, it is unclear by what you mean by third layer contact.

Nevertheless, I would try to clarify your question about how vulnerable you are to the infection. You can assess your risk by answering the quiz here Assess Your Risk.

At the end of the test, you will be categorized into different risk group and please act accordingly. If you’re in low or medium low, you’ll only need to practice hygiene and monitor the symptoms. If you’re in medium-high risk you’ll be required to be quarantine for 14 days and if you’re in high risk group you’ll need to come to the hospital immediately.

For more information on coronavirus, please visit the official Ministry of Health portal at link here (MOH COVID-19 Portal). You can also consult a doctor for free regarding your condition by clicking Ask Doctor link on the portal.

I hope this is somehow helping. Thank you.
