The clinical presentation, management and outcomes of patients during the Delta and Omicron outbreaks were compared.<h4>Results</h4>A total of 44 PD patients developed SARS-CoV-2 infection (23 during the Delta wave and 21 during the Omicron wave): median age 66 (60.5-68.5) years, male (63.6%), Chinese ethnic (77.3%), diabetes mellitus (56.8%), and cardiovascular disease (45.5%). Approximately, 93.2% received two doses of the mRNA COVID-19 vaccine. Cough (81.8%) and fever (54.5%) were common presenting symptoms. Chest radiography showed ground glass opacity in 23.5% of patients, consolidation in 55.6%, and bilateral lung involvement in 33.3%. Eleven patients (25.6%) received antiviral therapy (Remdesivir), 7 (16.3%) received steroid, and 4 (9.3%) received monoclonal antibodies. Patients infected during the Delta wave were more likely to be hospitalized (73.9 vs 14.3%; p < 0.001) and receive antiviral therapy (39.1 vs 10.0%; p = 0.03) than those during the Omicron wave. The overall mortality rate was 11.4%, with significantly higher mortality during the Delta wave than during the Omicron wave (21.7 vs 0%; p = 0.03).<h4>Conclusions</h4>The mortality rate was high among infected PD patients during Delta wave of COVID-19 infection.
