COVID-19

COVID-19 is an infectious respiratory disease caused by the novel coronavirus SARS-CoV-2, which has demonstrated significant global impact through rapid transmission and multi-system involvement. The infection ranges from asymptomatic cases to severe respiratory failure and long-term complications affecting multiple organs. This session at the Infectious Diseases Conference focuses on clinical characteristics, transmission dynamics, public health response, and evolving management strategies for COVID-19.

Transmission primarily occurs through respiratory droplets, aerosols, and close contact with infected individuals, with additional risk from contaminated surfaces in certain settings. The disease presents with symptoms such as fever, cough, fatigue, and breathlessness, while severe cases may progress to pneumonia and acute respiratory distress syndrome. Emerging variants have influenced transmissibility and immune response, making continuous monitoring essential.

Diagnostic advancements such as RT-PCR testing, antigen detection, and genomic sequencing have played a critical role in identifying cases and tracking viral mutations. Vaccination programs have significantly reduced severe disease outcomes, while public health measures including masking, distancing, and hygiene practices have helped control spread during peak transmission periods.

In clinical and epidemiological contexts, Coronavirus Disease 2019 is used to describe the same condition, emphasizing its viral origin and global outbreak classification. This session provides a comprehensive overview of COVID-19 management, highlighting lessons learned, response strategies, and preparedness frameworks for future pandemics.
