OVID-19 is a disease caused by the coronavirus SARS-CoV-2. It first appeared in late 2019 and quickly spread around the world, becoming a global pandemic. Causes: COVID-19 is mainly spread through respiratory droplets when an infected person coughs, sneezes, or talks. It can also spread by touching contaminated surfaces and then touching the mouth, nose, or eyes. Symptoms: The most common symptoms include fever, cough, tiredness, and loss of taste or smell. Some people may experience difficulty breathing, sore throat, muscle aches, or headaches. In severe cases, it can lead to pneumonia or death. Treatments: Most people recover at home with rest, fluids, and over-the-counter medicine to reduce fever and pain. In more serious cases, patients may require hospitalization, oxygen therapy, or ventilator support. Cure: There is no specific cure for COVID-19, but vaccines have been developed to prevent serious illness. Vaccination, along with hygiene measures like handwashing and mask-wearing, helps protect against the virus.
