What is the effect of weather on cold sores?

<p style=";text-align:left;direction:ltr">Arab Weather - <strong>Cold sores are a skin condition that affects about 90% of people at least once in their lives</strong> , and it is one of the diseases that are affected by many environmental and pathological factors, including <strong>the weather and climate-related diseases</strong> . Cold sores appear in the form of bubbles in different areas of the skin <strong>as a result of a viral infection</strong> , and these areas include:</p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> Lips and around.</li><li style=";text-align:left;direction:ltr"> Nostril.</li><li style=";text-align:left;direction:ltr"> the chin.</li><li style=";text-align:left;direction:ltr"> Cheeks.</li><li style=";text-align:left;direction:ltr"> The gums and roof of the mouth.</li></ul><p style=";text-align:left;direction:ltr"> The virus that causes cold sores, a <strong>1</strong> <strong>herpes virus type I</strong> ( in <strong>English: Herpes simplex virus- type-)</strong> severe virus infection, is <strong>transmitted through</strong> the <strong>skin or fluids of infected persons. The virus infection begins after a period of up to twenty days after contact with the infected person, and it lasts about a week to ten days.</strong></p><p style=";text-align:left;direction:ltr"> It is estimated that about two-thirds of people have previously had a type 1 Herpes virus infection, but this infection does not necessarily lead to cold sores. When infected with Herpes virus, the virus may remain dormant for long periods within nerve cells until exposure to a stimulus, causing cold sores. These triggers may vary from person to person, and <strong>include:</strong></p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> Have a fever.</li><li style=";text-align:left;direction:ltr"> Cold weather.</li><li style=";text-align:left;direction:ltr"> Eat some foods.</li><li style=";text-align:left;direction:ltr"> Exposure to daily stress.</li><li style=";text-align:left;direction:ltr"> Exposure to sunlight.</li><li style=";text-align:left;direction:ltr"> Catching a cold.</li><li style=";text-align:left;direction:ltr"> Fatigue.</li><li style=";text-align:left;direction:ltr"> menstruation.</li></ul><p style=";text-align:left;direction:ltr"> <strong>Some bouts of cold sore may recur on a monthly basis, while others may occur intermittently during the year</strong> . Also, the bodies of some people may build antibodies to the virus, which prevents it from recurring. In addition, cold sores may develop into an infection that causes inflammation of the tonsils and throat in adults. And cold sores often follow a specific pattern in their appearance. At first, the patient feels tingling or itching around the mouth or the area of the infection, and then the sores appear in the form of water bubbles around the edges of the mouth, accompanied by pain and irritation. In the end, these bubbles die, their secretions leak out, and then a yellow crust forms, which disappears after a while.</p><h2 style=";text-align:left;direction:ltr"> Cold sores during the winter</h2><p style=";text-align:left;direction:ltr"> When you get an infection with the Herpes virus that causes cold sores, the virus remains dormant for long periods until you are exposed to a trigger that you may get a cold sore after.
