Suppression vs Mitigation
Bulletin 5 | Adrian Pinington
Suppression strategies seek to reduce the spread of this epidemic by aggressive identification of infected individuals, with strict isolation of them. Innovative contact tracing and testing, has shown success in slowing the epidemic in countries like Singapore, China, Taiwan and South Korea. However, this leaves the population without immunity and susceptible to recurring outbreaks. Mitigation strategies seek to manage spread of infection through a population by significantly reducing social interaction between and among population subgroups. Specific isolation measures are implemented for vulnerable subgroups expected to be most adversely affected by infection. Success depends on: - getting timing + level of reduced social interaction right so health services are not overwhelmed, - high levels of compliance with social distancing, - successful identification and isolation of vulnerable subgroups, and - acquisition of long term immunity by those who have been infected.
