COVID-19 Surveillance Systems

COVID-19 surveillance systems are methods used by health officials to monitor and track the spread of the virus. They collect data from hospitals, clinics, testing centers, and laboratories about new cases, hospitalizations, and deaths. This information helps identify outbreaks, understand transmission patterns, and assess the impact of the pandemic. Surveillance can include testing, contact tracing, and analysis of trends over time. These systems enable timely responses, inform public health policies, and help allocate resources effectively to control the spread of COVID-19.
