What happens when a wart gets infected?

When a wart gets infected, it may become red, swollen, and painful, and there can be an increase in pus or drainage from the area. The infection can cause the wart to grow larger and may lead to additional complications, such as the spread of the infection to surrounding skin. Infected warts may require medical treatment, such as antibiotics or drainage, to resolve the infection and alleviate symptoms. It's important to avoid picking at or irritating the wart to prevent further infection.
