Abstract
INTRODUCTION: Recently, many studies have observed a marked difference in characteristic of patients whom were detected positive COVID-19 during the dominance of Delta variant in the middle of year 2021 as compared to the cases reported during the peak of Omicron wave in early 2022. In Federal Territory (FT) of Putrajaya, a cumulative total of 21,049 cases was registered from the 1st case reported in March 2020 until the Epidemiology Week (EW) 23 in the year 2022. The initial uprise in cases was observed from EW-25/2021 until EW-38/2021, whereby many countries had also confirmed the Delta variant spread within their communities. In 2022, another drastic increment of cases was reported in Putrajaya beginning EW-5/2022, which coincided with the emergence of Omicron variant globally.
OBJECTIVE: This cross-sectional analysis aims to describe the situational analysis of COVID-19 cases in FT Putrajaya, in particular the characteristics of COVID-19 cases registered during both the Delta and Omicron wave from 2021 until 2022.
METHODOLOGY: Secondary data from the line listing of COVID-19 cases registered under FT Putrajaya was extracted from the period of EW-25 in 2021 until EW-23 in 2022. Disease severity was categorised by the clinical stage upon initial diagnosis, referring to the COVID-19 Management Guidelines in Malaysia No.5/2020 (Annex 2e updated 31/05/2022). Data analysis was performed using IBMM SPSS version 25.
RESULTS: Preliminary results revealed that there were 7,256 cases reported from EW25/2021 until EW52/2021. More than half were males with nearly one-third aged between 31 to 40 years old. 1988 (27.4%) cases had comorbid. Less than half of cases had completed 2 doses of COVID-19 vaccination and 1.6% had received booster shots, however 50.6% were either unvaccinated or had only completed 1 dose. Majority (97.9%) cases were either asymptomatic or had mild illness, whereas 149 (2.1%) cases had severe disease upon diagnosis. In comparison, there were 11,639 cases reported in 2022 (until EW-23/2022), whereby mostly were females (53.1%) and at least two-third of cases were in the working or reproductive age group, followed by children aged 10 years and below. 22.1% of cases also reported one or more comorbidities. In terms of COVID-19 vaccination, at least 67.2% cases had completed 2 doses and 32.8% cases either had not been vaccinated or only received 1 dose. 6.5% cases had received the booster shot. Majority (99.2%) of cases were asymptomatic or mild, whereas 0.8% developed severe disease. Disease severity is reportedly lower in the 2022 cohort as compared to the 2021 cohort and this may reflect the larger percentage of vaccinated individuals in 2022. DISCUSSION & CONCLUSION: These preliminary findings revealed that despite the surge of different variants, factors such as age and comorbidity remained consistent with COVID-19 infection in general. Majority of cases in Putrajaya were not severely ill upon their diagnosis and most had been vaccinated. Therefore COVID-19 vaccination should be recommended as a permanent fixture in the Malaysian National Immunisation Program, particularly for high-risk groups such as children, elderly and those with comorbidities.
