What is the best disinfectant for Hepatitis A virus?

Explanation:
Hepatitis A virus is a non-enveloped virus, so it resists many common sanitizers like alcohol and some quats. Oxidizing agents that disrupt proteins and nucleic acids are more reliable for inactivating non-enveloped viruses, and sodium hypochlorite (bleach) is a well‑tested disinfectant for HAV. When used at the proper concentration and given enough contact time, bleach effectively inactivates HAV on surfaces, utensils, and in water. Hydrogen peroxide, iodine, or alcohol are less consistently effective against HAV, especially on soiled surfaces, making bleach the best choice in this scenario. Always prepare a fresh chlorine solution and follow recommended contact time and safety guidelines.
