Timely treatment of patients at risk for severe COVID-19 prevents severe outcomes
Dr. Asok Kurup, Dr. Alex Soriano, 31 Oct 2022

Despite widespread uptake of vaccinations, COVID-19 remains a serious health issue for high-risk patients, owing to the emergence of new variants of concern (VOCs), waning immunity, and breakthrough infections.

At a recent symposium in Singapore, esteemed experts Dr Asok Kurup, Consultant Infectious Diseases Physician at Mount Elizabeth Medical Centre, Singapore, and Dr Alex Soriano, Head of Infectious Diseases Department, Hospital Clínic of Barcelona and Assistant Professor, University of Barcelona, Spain, gave insights on the evolution of global trends since the start of the COVID-19 pandemic and discussed key challenges in managing high-risk patients with COVID-19 in the ICU. They also highlighted early treatment strategies to minimize the burden of COVID-19 on healthcare systems.

Burden of Dengue amidst the COVID-19 Pandemic
12 Jul 2022
Dengue fever (DF) is endemic in many tropical countries, including Singapore, and is spread by Aedes mosquitoes. All four serotypes of the dengue virus (DENV 1–4) are found in Singapore, with serotype distribution fluctuating from year to year. DENV-1 and DENV-2 were previously the dominant serotypes in outbreaks, but DENV-3 has now replaced DENV-2 as the most common serotype in 2022. Along with a larger proportion of people staying home due to the COVID-19 pandemic, this has resulted in an increase in dengue incidence in Singapore. In the week of 12th to 18th June 2022, 1,258 new dengue cases were reported. According to the National Environment Agency (NEA), this number is expected to rise and exceed the highest weekly figure of 1,787 cases recorded in 2020.
