Fever Blister - Herpes Simplex Infections

What can be done to prevent the infection?

The herpes simplex virus can be passed from person to person. Someone with oral herpes should not share lipstick, utensils, or drinks with others. Touching and kissing can also spread the virus. Someone with genital herpes should use condoms during sexual activity to help prevent the spread of the infection. People who have immune system problems or who have frequent recurrences often take antiviral drugs, such as acyclovir and valacyclovir, to help prevent reactivation. A doctor who specializes in the condition should monitor a pregnancy complicated by HSV infection.

What are the long-term effects of the infection?

Most infections clear up in 3 weeks or less. But the infection is chronic because the virus stays in the body forever. So, it may come back over and over throughout the rest of the individual's life. Infection in newborn babies and people whose immune systems are not working well can result in brain damage or death.

What are the risks to others?

Herpes infections are highly contagious and can be passed from one person to another much like a cold or the flu. Good hand washing, wearing gloves, and avoiding direct contact can all help prevent the spread to others.
