Which of the following methods can help minimize the risk of viral infections?

Frequent hand washing is a highly effective method for minimizing the risk of viral infections because it helps remove pathogens from the skin. Hand washing with soap and water or using an alcohol-based hand sanitizer can significantly reduce the number of viruses present on the hands, which is crucial since many viral infections are transmitted through touch and contact with contaminated surfaces. Proper hand hygiene interrupts the transmission cycle and protects not just the individual washing their hands but also those they come into contact with.

In contrast, wearing minimal clothing does not have any relevance to viral transmission, using shared utensils can increase the risk of spreading viruses, and staying indoors may not effectively prevent exposure to viruses if proper hygiene practices are not followed. Thus, frequent hand washing stands out as the most reliable method for reducing the risk of viral infections.
