Oral viral herpes is contagious and can be transmitted through direct contact with droplets, saliva or herpes fluid. It can also be transmitted to the body through clothing or through the mouth, nose, eyes, conjunctiva, genitals, etc. Therefore, it is recommended that patients with herpes should be isolated as much as possible to avoid contagion. In addition, it is recommended that timely control of the lesion can be achieved by using healing and antiviral drugs. Antiviral medications are generally chosen from acyclovir ointment, and oral valacyclovir or acyclovir can also be taken as appropriate. In addition, you can use local medications to promote healing, for example, after the herpes has broken down, you can choose to use topical tin powder, pearl yellow powder, nourishing Yin and muscle powder, or choose to gargle mouthwash such as compound chlorhexidine gargle, can be conducive to antibacterial treatment.
