Quick takeaways

  • Physical barriers like skin and mucosal linings help prevent the entry of cold and flu viruses, so be careful about touching your eyes, nose, and mouth after touching potentially contaminated surfaces or shaking hands.
  • The innate immune system mounts a rapid response to neutralize and destroy cold and flu viruses by deploying white blood cells and releasing cytokines to assist healing.

Deep dives

Physical barriers and portals of entry for colds and flus

The body has physical barriers, such as the skin, mucosal linings, and chemicals on the surface of the eyes, nose, and mouth, that help prevent the entry of cold and flu viruses. The primary entry sites for these viruses are the eyes, nose, and mouth. It is important to be mindful of touching these areas after shaking hands or touching surfaces that may be contaminated with the viruses.
