What is the best preventive measure against rotavirus infection?

Good personal hygiene is the best preventive measure against rotavirus infection because rotavirus is primarily spread through the fecal-oral route. This means that the virus can be transmitted from person to person, often when an infected individual does not wash their hands properly after using the bathroom. Practicing good personal hygiene, particularly thorough handwashing with soap and water at critical times—such as before eating, after using the toilet, and after changing diapers—can significantly reduce the likelihood of spreading the virus.

While cooking food thoroughly, pasteurizing milk, and freezing leftovers are important food safety measures that help prevent various types of foodborne illnesses, these practices are not specifically effective against rotavirus, which is not transmitted through food in the same way as pathogens that cause foodborne illnesses. Therefore, they are less effective in preventing the spread of rotavirus compared to maintaining good personal hygiene.
