COVID-19, also known as Coronavirus Disease 2019, is an infectious respiratory illness caused by the SARS-CoV-2 virus. It first emerged in December 2019 and has since spread globally, leading to a pandemic. COVID-19 primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. Symptoms of COVID-19 can range from mild to severe and include fever, cough, fatigue, muscle aches, loss of taste or smell, and difficulty breathing. The disease has had a significant impact on public health, the economy, and daily life worldwide.

Tracking COVID-19 is important for several reasons. First, it allows us to monitor the spread of the virus in our communities, identify areas with high infection rates, and make informed decisions about public health measures to control the spread of the virus.

Second, tracking COVID-19 helps us to understand the impact of the virus on public health. By monitoring the number of cases, hospitalizations, and deaths, public health officials can identify trends, evaluate the effectiveness of interventions, and make recommendations to protect the health of individuals and communities.

Third, tracking COVID-19 is essential for developing treatments and vaccines for the disease. By studying the virus and its impact on the body, researchers can identify potential treatments and develop vaccines to prevent the disease from spreading further.

Finally, tracking COVID-19 helps us to plan and prepare for future pandemics. By learning from our experiences with COVID-19, we can improve our public health infrastructure and response capabilities to better protect ourselves from future outbreaks.
