What is a "corona"?

A corona is a decorative molding or horizontal band that typically appears at the top of a wall or column, often serving as a transition between the vertical and horizontal elements of a structure. In architecture, the corona can be seen in cornices or overhangs, helping to define the upper edge of a building or space. This feature is commonly found in classical architecture and adds visual interest, enhancing the overall design while providing a sense of completion to the structure. The corona can also help to protect the walls from rain and moisture.

What is "corona"?

Corona, or COVID-19, is an infectious disease caused by the SARS-CoV-2 virus. It mainly spreads when an infected person talks, coughs, or sneezes, releasing saliva or mucus. Symptoms can vary widely but often include fever, cough, difficulty breathing, fatigue, and loss of taste or smell. While many people experience mild symptoms, others may develop serious complications, especially older adults and those with underlying health conditions. Prevention measures such as wearing masks, practicing good hand hygiene, and getting vaccinated help reduce the spread of the virus and protect individuals from serious illness.
