Sodium Hypochlorite (Bleach) Effectiveness Against Swine Flu Virus

Yes. WHO confirms that 0.5% sodium hypochlorite (5,000 ppm) effectively inactivates the H1N1 influenza virus (swine flu) on surfaces.

Usage Guidelines

• Dilution: 1:10 of 5.25–6.15% household bleach → ~0.5% (5,000 ppm).
• Contact time: ≥1 minute for enveloped viruses like influenza.
• Surface prep: Clean visible soil first; organic matter inactivates bleach.
• Safety: Ventilate area; wear gloves; never mix with ammonia/acids (toxic gas).
• Test patch: Check for surface damage/discoloration.

Bleach is a broad-spectrum disinfectant for bacteria, viruses, fungi, and spores when used correctly.
