How High Temperatures Can Eliminate the Coronavirus

The new coronavirus SARS-CoV-2 has caused the respiratory illness, COVID-19. Its mild to serious nature has spurred numerous efforts towards its elimination. One of the key strategies involves understanding how high temperatures can inactivate this virus. This article delves into the specific conditions required to achieve this, supported by recent research findings.

The Effectiveness of High Temperatures

Medical research has consistently shown that high temperatures can kill coronaviruses. This knowledge holds true for SARS-CoV-2 as well. However, the exact temperature and duration necessary for complete inactivation can vary depending on several factors, including the concentration of the virus and the type of surface. Understanding these variables is crucial for effective disinfection.

Temperature and Inactivation: A Case Study

To determine a reliable temperature for inactivating SARS-CoV-2, researchers looked at the impact of another coronavirus, SARS-CoV, which causes SARS (Severe Acute Respiratory Syndrome) and is closely related to SARS-CoV-2. A comprehensive analysis revealed that temperatures exceeding 65°C could effectively kill the virus.

Specifically, the researchers estimated that heating the virus at 65°C for a sufficient amount of time can ensure its complete inactivation. Furthermore, they suggested that increasing the temperature by 10°C might enhance the effectiveness of the process. Consequently, heating the virus to 75°C for at least three minutes can eliminate the coronavirus.

Implications for Vaccines and Storage

An interesting aspect of this research is the impact on the storage and transportation of vaccines. For instance, vaccines like those developed by Pfizer and Moderna must be stored at extremely cold temperatures, typically between 2°C and 8°C. This requirement is critical for maintaining vaccine efficacy. Any deviation from these storage conditions can significantly reduce the vaccine's effectiveness.

The need for precise temperature control has driven advancements in medical refrigerators and ultra-cold freezers.

Other Considerations

It's also important to note that the time required to inactivate the virus on surfaces depends on the amount of virus present. For instance, a period of 20 minutes at 92°F (approximately 33°C) can effectively inactivate the virus on surfaces if the concentration is not excessively high.

In summary, understanding the impact of temperature on SARS-CoV-2 helps in developing effective methods to eliminate the virus. Factors such as the temperature, duration, and surface type must be considered to ensure comprehensive inactivation. This knowledge is vital in combating the spread of COVID-19 and safeguarding public health.
