The recent surge in COVID-19 cases in Singapore has sparked concerns and prompted swift actions from the Singapore Health Ministry to safeguard hospital capacities. During the week of May 5 to 11, the country witnessed a staggering 90% increase in COVID-19 infections, with the number reaching 25,900 compared to 13,700 cases in the previous week. This surge has led to an elevation in the average daily COVID-19 hospitalisations, rising to around 250 from 181 the week before. Despite this alarming increase, the average daily cases in intensive care units have remained relatively low at three cases, compared to two cases in the preceding week.
The Ministry of Health of Singapore (MOH) is vigilantly monitoring the trajectory of this wave and has taken proactive measures to maintain hospital bed capacity. Public hospitals have been instructed to reduce non-urgent elective surgeries and transfer suitable patients to Transitional Care Facilities or provide care at home through Mobile Inpatient Care@Home. Additionally, individuals with mild symptoms or no medical vulnerabilities are advised not to seek treatment at hospital Emergency Departments.
The predominant strains responsible for the rise in cases in Singapore are the KP.1 and KP.2 variants of the COVID-19 virus, which collectively account for over two-thirds of infections. These variants are part of a lineage known as “FLiRT”, derived from the JN.1 variant that spread globally several months ago. The World Health Organization recently classified the KP.2 variant as a Variant Under Monitoring. This variant has become dominant in the United States and has been detected in various countries worldwide, including China, Thailand, India, Australia, and the United Kingdom.
Despite the prevalence of these new variants, there is currently no evidence suggesting that the KP.1 and KP.2 strains are more transmissible or result in more severe illness than other circulating variants. The MOH emphasised the importance of staying informed about COVID-19 vaccinations. The ministry will be sending SMS reminders to individuals who have not received a COVID-19 jab in the past year to prompt them to schedule an appointment.
Approximately 80% of the local population have received their initial or additional vaccine doses; however, those who have not been vaccinated within the last year may experience waning immunity. It is crucial for individuals to remain vigilant even as COVID-19 transitions into an endemic phase.
To encourage vaccination uptake, Joint Testing and Vaccination Centres will extend their operating hours on Saturdays and the eve of public holidays from May 21 to June 29. Additionally, participants in the Healthier SG initiative can receive vaccinations at over 250 participating clinics islandwide, with more clinics set to be added gradually. Mobile vaccination teams will also be deployed to selected areas to reach out to residents, particularly seniors.
The MOH reiterated that COVID-19 vaccines are safe and effective, citing data from the previous JN.1 wave in December 2023. During that peak period, unvaccinated seniors aged 60 and above had a 25% higher incidence rate of COVID-19 hospitalisations and ICU admissions compared to those who had kept up with their vaccination schedule.
The recent surge in COVID-19 cases in Singapore has prompted proactive measures from the Health Ministry to safeguard public health and hospital capacities. The emergence of the KP.1 and KP.2 variants underscores the importance of vaccination and vigilance in combating the spread of the virus. By extending vaccination centre hours and deploying mobile teams, authorities are striving to ensure widespread access to vaccination services and protect vulnerable populations from severe illness. It is imperative for individuals to heed MOH’s advice, stay informed about vaccination opportunities, and continue practising preventive measures to curb the transmission of COVID-19.
