Which disease is caused by the virus SARS-CoV-2?

The disease caused by the virus SARS-CoV-2 is COVID-19. This virus was first identified in late 2019 and is responsible for the global pandemic that followed. COVID-19 primarily affects the respiratory system, but it can also have implications for other body systems, leading to a wide range of symptoms from mild cold-like symptoms to severe respiratory distress and even death in some individuals.

Other options represent different diseases caused by separate pathogens. Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. MRSA stands for Methicillin-resistant Staphylococcus aureus, which is a type of bacteria resistant to many antibiotics. Hepatitis A is caused by the hepatitis A virus, which primarily affects the liver. Understanding the specifics about SARS-CoV-2 helps to recognize the importance of public health measures to control the spread of COVID-19.
