Cold sores are blister-like tiny lesions that appear near or on the lips, cheeks, chin and inside the nostrils. In rare cases, they can also affect areas of the mouth like the roof and gums. Herpes simplex virus triggers this condition and quickly spreads via physical contact. According to the WHO report, two-thirds of population aged more than 50 years have HSV-1. Also, about 90% of the adults worldwide test positive for HSV-1, but only 30% show the signs of the infection. So some people never show any symptoms throughout life, but some may have to deal with them again with the recurring breakouts.

When the virus enters the body for the first time, the breakout can be quite severe. It can be accompanied by a sore throat, headache and even fever. Cold sores last for seven to ten days. But it doesn’t mean that the virus will leave your body. It remains inside the cells in a dormant state. It can be triggered again by many factors like stress, allergies, menstruation, fever, sunburns, diet, unwarranted consumption of medications, etc. People with the regular outbreak or those with the weak immune system are recommended to seek medical advice for cold sore treatment.

As cold sore is a viral infection, so it can be easily transmitted from an infected person. A study reveals, HSV-1 virus is present in maximum people but is in a dormant state. The virus doesn’t have their own life base and can be active or alive inside organisms and affect the immune system, so it is not possible to eliminate them. Although, their impact and severity can be reduced with the help of medications and boosting the immune system.
