Synopsis: Every first and third Wednesday of the month, The Straits Times helps you make sense of health matters that affect you.

Singapore is gradually opening its borders to allow for quarantine-free travel as it moves towards a new normal of living with Covid-19. However, at home, restrictions remain in place to protect the unvaccinated seniors and prevent hospitals from becoming overwhelmed.

The country is seeing very high numbers of daily Covid-19 cases, with a considerable number of people in the hospitals and about 10 or more dying from complications linked to Covid-19. Unvaccinated older adults account for most of these deaths, though some vaccinated people have also succumbed to the complications of the disease.

ST senior health correspondent Joyce Teo speaks with Associate Professor Hsu Li Yang, an expert on infectious diseases at the NUS Saw Swee Hock School of Public Health to find out more.
