Herpes simplex is a common viral infection that affects millions of people worldwide. Despite its prevalence, it’s often misunderstood and surrounded by stigma. In reality, herpes simplex is manageable and typically not life-threatening.
What is Herpes Simplex?
Herpes simplex is caused by the herpes simplex virus (HSV). There are two types: HSV-1 and HSV-2. HSV-1 usually causes oral herpes, which appears as cold sores or fever blisters around the mouth. HSV-2 typically leads to genital herpes, which results in sores around the genital or anal area. However, both viruses can infect either area through skin-to-skin contact (World Health Organization [WHO], 2022).
How Common is It?
Herpes is extremely common. According to the WHO (2022), an estimated 3.7 billion people under the age of 50 have HSV-1 globally, and about 491 million people aged 15–49 have HSV-2. Most people get infected in childhood or early adulthood. Many don’t even know they have the virus because it may not show any symptoms.
How is Herpes Transmitted?
Herpes spreads through direct contact with the virus, which can happen even when there are no visible sores. This includes kissing, oral sex, vaginal or anal sex, and sharing personal items like lip balm or razors. HSV enters the body through the skin or mucous membranes, such as the mouth, genitals, or eyes (Centers for Disease Control and Prevention [CDC], 2023).
Once infected, the virus stays in the body for life. It hides in nerve cells and can reactivate from time to time. Some people have frequent outbreaks, while others may have only one in their lifetime.
Symptoms of Herpes Simplex
Symptoms vary from person to person. Some people experience painful blisters or sores at the site of infection, itching, burning, or flu-like symptoms such as fever and swollen glands. (CDC, 2023).
After the first outbreak, the virus becomes inactive but can reactivate later, especially during times of stress, illness, or a weakened immune system. These recurrences are usually milder than the first outbreak.
Diagnosing Herpes
Doctors typically diagnose herpes through a physical exam and lab tests. A sample from a sore can be tested to confirm the presence of HSV. Blood tests can also detect HSV antibodies, which show if someone has been exposed to the virus, even without symptoms (Mayo Clinic, 2023).
Treatment and Management
There is no cure for herpes, but antiviral medications like acyclovir, valacyclovir, and famciclovir can help manage the symptoms. These drugs can speed up the healing process during an outbreak, reduce the number of future outbreaks, and lower the risk of transmission to others (CDC, 2023).
Managing herpes also involves lifestyle choices. Getting enough rest, reducing stress, eating a healthy diet, and avoiding triggers like illness or sun exposure can help prevent outbreaks.
Preventing Herpes Spread
To prevent spreading the virus to others:
- Avoid intimate contact during an outbreak.
- Use condoms or dental dams, though they don’t offer complete protection.
- Take daily antiviral medicine if recommended by a doctor.
- Communicate openly with sexual partners about STIs and get tested regularly (CDC, 2023).
It’s also important to note that herpes can be passed from mother to baby during childbirth, which can be serious. Pregnant women with herpes should inform their doctor so steps can be taken to protect the baby (WHO, 2022).
Herpes simplex is a lifelong virus, but it’s manageable. With the right treatment and precautions, people with herpes can reduce outbreaks and transmission. Understanding the virus, knowing the facts, and reducing stigma are essential steps in supporting those who live with herpes and preventing its spread.
