Coronavirus refers to a large family of viruses that can cause illness in animals and humans. In humans, these viruses can lead to respiratory infections, ranging from the common cold to more severe diseases like COVID-19. The outbreak of COVID-19 in late 2019 highlighted the potential severity of coronaviruses and their impact on global health. The symptoms of coronavirus infections can vary widely, but common signs include fever, cough, and difficulty breathing. Preventative measures such as vaccination, wearing masks, and practicing good hygiene are essential in controlling the spread of these viruses. Understanding coronaviruses is crucial for public health and safety.
