Is oral herpes contagious? People with low immunity should pay attention

Oral herpes is caused by a viral infection. Clinical studies have found that oral herpes is also contagious to a certain extent. People with low immunity are especially more susceptible to this disease. If you have oral herpes, you should take good care of your oral cavity, eat a light diet, and get enough rest.

1. Is oral herpes contagious?

Herpes labialis, also known as shingles, is caused by a viral infection. In the past, it was believed that shingles was not contagious. However, clinical observations at home and abroad in recent years have found that shingles is still contagious to a certain extent, especially for infants, pregnant women, people with weakened immune systems, people who have never had chickenpox, and people who have not been vaccinated against chickenpox who have had close contact with shingles patients.

The blister fluid of patients with shingles contains a large amount of virus. People with shingles should avoid close contact with people with weakened immunity, such as infants and young children. For normal and healthy adults, since they have relatively sound immune mechanisms and resistance, they are generally not infected, so there is no need for deliberate isolation.

2. Care for herpes labialis

1. Fresh and light diet: Do not eat stale, spoiled or irritating food; it is recommended to eat more fresh fruits and vegetables rich in vitamin C; choose light-tasting, easily digestible food to keep bowel movements smooth; you can drink more yogurt, mushroom soup, and kelp soup.

2. Pay attention to oral hygiene. Develop the good habit of rinsing your mouth after eating and brushing your teeth before going to bed, especially not eating after brushing your teeth. It is best to rinse your mouth with light salt water 1 to 3 times a day.

3. Prevention of herpes labialis

To prevent oral herpes, first of all, you need to ensure enough sleep and take a nap at noon. Secondly, pay attention to adjusting your diet structure and eat more fresh vegetables and supplement various vitamins. You should not just eat light food, but should combine meat and vegetables, diversify your food, drink plenty of water, and maintain a nutritional balance in the body. This is the only way to enhance the body's immunity and prevent the occurrence of herpes. Patients with fever must pay attention to oral hygiene and develop the good habit of rinsing their mouths after eating, brushing their teeth before going to bed, and especially not eating after brushing their teeth.
