Kissing can transmit herpes virus linked to dementia

Kissing can lead to more than just dry lips; recent research has revealed serious health risks. A common virus, the herpes simplex virus type 1 (HSV-1), can be transmitted through kissing and may harm the brain. Scientists from the University of Illinois at Chicago discovered that HSV-1 is capable of using an enzyme to enter the nervous system. This can result in brain inflammation and potential long-term issues, such as dementia. Prof. Deepak Shukla, who led the study, warned that close contact increases the chance of catching the virus. HSV-1 is widespread, affecting nearly two-thirds of the global population. Most people do not show symptoms, but it can cause painful sores around the mouth. The virus spreads through contact with sores, saliva, or the areas near the mouth. Though primarily associated with oral infections, HSV-1 can also cause genital herpes through oral-genital contact. Meanwhile, HSV-2, another strain of the herpes virus, spreads mainly through sexual contact. Research indicates that once HSV-1 enters the nose, it can quickly reach the brain with the help of an enzyme called heparanase. This can lead to inflammation and neurological issues over time.
