Guide To The Causes And Risk Factors For Cold Sores

Viral Infection

Although the common cold does not cause HSV-1, it can still be indirectly responsible for future outbreaks. Similar to fatigue, viral infections will wear down the body and cause immune system changes that can trigger the sores, and this correlation is likely how the blisters received their colloquial names. Although the herpes simplex virus is the specific virus responsible for the initial infection, other viruses prevent the immune system from keeping the blisters dormant. Likewise, being out in regularly cold climates can have an impact on an individual's immune system, causing more outbreaks than other climates.

For example, they should be sure to drink plenty of fluids, keep bundled up, consider staying indoors, and nap to keep rested.
