What temperature kills hantavirus?

Hantavirus is effectively inactivated by temperatures at or above 115 degrees Fahrenheit (46 degrees Celsius).

Effective Heat Disinfection

Hantaviruses are known to be sensitive to heat, and exposure to elevated temperatures is a reliable method for their inactivation. For practical disinfection, a temperature of at least 115°F (46°C) is sufficient to kill off any lingering hantaviruses, especially on items that can withstand heat treatment.

Practical Application: Disinfecting Washables

This temperature threshold is particularly useful when cleaning items that may have come into contact with the virus, such as fabrics and other washables. To ensure proper disinfection through heat:

• Washing First: Always thoroughly wash contaminated fabrics and washables before drying.
• High-Temperature Drying: After washing, place the items into a dryer. Set the dryer to a high heat setting, ensuring the internal temperature reaches or exceeds 115°F (46°C).
• Duration: Maintain the high heat for a sufficient period to ensure all parts of the items reach the inactivating temperature. Most standard high-heat dryer cycles will achieve this.
