Herpes Simplex Virus: Symptoms, Causes, Prevention and Treatments

Dr. SatabdiDec 24, 2024

The Herpes Simplex Virus (HSV) comes in two varieties: HSV-1 and HSV-2. Both forms can cause oral and genital herpes, even though they are usually associated with different regions. In most cases, herpes is not lethal and does not cause serious health problems. Although herpes outbreaks can be painful and annoying, the initial flare-up is usually the worst. Several bodily areas can become infected with herpes.

Whether it is the first time or a recurrence, medications are frequently used to treat herpes outbreaks. Although these medications cannot treat herpes, they can lessen its symptoms and shorten its duration.

You should schedule a visit with a healthcare professional if you believe you have herpes. You should be ready to respond to inquiries regarding your medical history, sexual history, and symptoms.

What is Herpes?

Herpes is a common infection caused by Herpes Simplex Virus. This infection is usually transmitted through intimate person-to-person contact. The infected persons experience water-filled blisters or sores that often heal without any scar. The sores usually take one or more weeks to heal completely.

What are the types of Herpes?

There are two types of Herpes viruses.

Herpes Simplex Virus-1 (HSV-1) is chiefly responsible for causing lesions around the mouth. This typically leads to cold sores or fever blisters on your face.
Herpes Simplex Virus-2 (HSV-2) causes lesions in the genital region, inner thighs, buttocks, and anus. Genital Herpes is a Sexually Transmitted Disease (STD).

It should be remembered that both viruses are capable of causing lesions around the mouth and genitalia. Many people with genital Herpes have HSV-1 infection, which they contracted through oral-to-genital contact.

How Do You Get Herpes?

The majority of herpes infections go undiagnosed. Herpes infection can appear as one or more blisters in those who do experience symptoms. These may appear on or close to the rectum, genitalia, eyes, or mouth. The blisters develop into sores or ulcers after they burst. Close touch is how the herpes virus travels from one person to another. Contact with an infected individual's sores or saliva can spread HSV-1. This could happen as a result of:

Kissing an infected person
Shared tumblers, glasses, or bottles of water
Oral sex
Shared makeup
Any other type of skin-to-skin interaction.

What Are the Symptoms of Herpes?

Herpes does not always present with symptoms. The symptoms vary depending on whether you are having the infection for the first time (primary HSV infection) or if it is a recurrence of an old infection.

Primary HSV infection occurs any time between a few days to a few weeks after the first exposure to the HSV virus. It presents with flu-like symptoms. These symptoms include the following.

A general feeling of being unwell
Loss of appetite
Fever
Swollen and painful lymph nodes
Pain in the area
Burning or tingling sensation in the area before the onset of the lesions

There may be a burning or tingling sensation in the area of infection before the development of small painful, fluid-filled blisters. The blisters may appear alone or may appear as clusters.

These would eventually burst and a crust appears over them before it begins to heal. Itching, popping, or breaking the blister may lead to scarring in the region. Otherwise, the lesion would heal over two to six weeks without any marks. Blisters continue to shed viruses until they are completely healed. Hence, direct contact with the blisters can lead to the transmission of infection. The sores in the genital region often cause pain during urination.

The virus that enters the body at the time of first exposure lives in an inactive state in the nerves. They may get re-activated occasionally, leading to recurrent infections. Some people may never experience recurrence.

Although initially, the recurrence can occur more frequently, as time progresses, the frequency of this recurrence comes down.

Recurrent HSV infection typically begins with a tingling sensation, burning, or itching in the area. Eventually, fluid-filled blisters appear in the area. These blisters shed viruses. Hence direct contact leads to the transmission of infection. The lesions heal over two to six weeks, often without any scars.

What is the Difference Between Genital Herpes and Oral Herpes?

Many individuals are unsure about the proper term for these illnesses because there are two distinct types of herpes. They are Oral & Genital Herpes, commonly known as HSV-1 and HSV-2. These are simple viruses that can infect different body parts. However, it is quite simple enough to know what type of herpes you are affected by Oral & Genital Herpes.

Oral Herpes	Genital Herpes
Oral herpes is the term for when you get either HSV-1 or HSV-2 in or around your lips, mouth, or throat. Fever blisters or cold sores are other names for oral herpes lesions.	Genital herpes is the term for when you get either HSV-1 or HSV-2 on or near your genitals (vulva, vagina, cervix, anus, penis, scrotum, butt, inner thighs).
Cold sores on your lips and around your mouth are a sign of an oral herpes infection. When they initially get infected, some patients experience herpetic gingivostomatitis.	A genital herpes infection results in sores on both the visible (such as your vulva or penis) and invisible (such as your cervix) parts of your genital area.

Oral Herpes

Genital Herpes

Oral herpes is the term for when you get either HSV-1 or HSV-2 in or around your lips, mouth, or throat. Fever blisters or cold sores are other names for oral herpes lesions.

Genital herpes is the term for when you get either HSV-1 or HSV-2 on or near your genitals (vulva, vagina, cervix, anus, penis, scrotum, butt, inner thighs).

Cold sores on your lips and around your mouth are a sign of an oral herpes infection. When they initially get infected, some patients experience herpetic gingivostomatitis.

A genital herpes infection results in sores on both the visible (such as your vulva or penis) and invisible (such as your cervix) parts of your genital area.

Every virus prefers to reside in its preferred location; HSV-1 typically causes oral herpes, whereas HSV-2 typically causes genital herpes. However, both forms of herpes simplex can potentially infect either region. For instance, oral sex with someone who has a cold sore on their lips can expose you to HSV-1 on your genitals. Additionally, oral sex with someone who has HSV-2 on their genitalia might result in HSV-2 in your mouth.

How is HSV Infection Diagnosed?

In most cases, your doctor will be able to diagnose HSV by its characteristic clinical appearance. The doctor may ask you for your history of fever, tingling, or burning sensation in the area.

In some cases, you may be advised to undergo further tests to confirm the diagnosis. It usually involves swabbing the fluid in the blister and sending it to a laboratory. In addition, you may also be advised to undertake certain blood tests.

How is Herpes Treated?

The main goal of treating Herpes is to prevent the transmission of the infection and prevent the shedding of the virus. Regardless of the treatment, the lesions gradually heal over three to four weeks. Antiviral medicines can, however, reduce the duration of the illness and ease your symptoms. The antivirals used include the following.

Acyclovir
Valacyclovir
Famciclovir
Foscarnet

Note: Take these medicines only under a physician’s advice.

What Are the Complications of HSV Infection?

In certain conditions, HSV infections can lead to complications. Here are some of these complications.

HSV and HIV: Human Immunodeficiency Virus (HIV) is a life-threatening sexually transmitted infection that reduces the body’s immune response, thus predisposing the affected person to multiple infections. HSV-2 is one of the most common infections seen among those living with HIV. HSV infection increases the likelihood of acquiring as well as transmitting HIV infection.
Severe HSV disease: In people with low immunity, such as those with HIV infection, there is frequent reactivation of HSV with severe disease presentation. In such people, it can lead to a brain infection called ‘Herpes encephalitis’. It is a serious, life-threatening condition.
Neonatal Herpes: A pregnant mother with genital Herpes can pass on the infection to the baby during pregnancy or childbirth. The babies may also acquire the infection shortly after birth, resulting in life-threatening neonatal Herpes infections. It is very important to screen mothers for Herpes infection.

How Do I Prevent HSV Infection?

The only sure way to prevent HSV infection is to abstain from any type of activity which would expose you to the virus. Since this is not always practically possible, here are some recommendations that help to reduce the risk of transmission.

Avoid sharing personal utensils and equipment with others.
Adopt safe-sexual practices.
Get yourself and your partner tested for Sexually Transmitted Infections and take the appropriate treatment if necessary.

Frequently Asked Questions

Here are some of the frequently asked questions on Herpes.

Is Herpes curable?

There is no cure for Herpes. However, antiviral medicines such as Acyclovir and Foscarnet help in reducing the intensity of the symptoms, frequency, and duration of the outbreaks. Long-term treatment with antiviral medicines can prevent the occurrence of outbreaks.

What triggers recurrent Herpes outbreaks?

Recurrent Herpes infections are triggered by stress, exposure to sunlight, illness, and fatigue. Sometimes, the menstrual period can trigger an outbreak.

What is Herpes labialis?

The Herpes lesions that occur on the lips are called Herpes labialis. They are referred to as cold sores or fever blisters. It appears as painful blisters that rupture, resulting in crusting over the area but heals over 10 to 15 days, often without a scar.

How do I protect myself from contracting genital Herpes?

You can protect yourself from contracting genital Herpes by adopting safe sex practices. These include using a condom during intercourse, not having multiple sexual partners, and abstaining from intercourse with a partner with genital Herpes.

I have oral Herpes. How do I prevent its transmission to other people?

You can prevent the transmission of oral Herpes by avoiding skin-to-skin contact with other people while you have an active lesion. It also means that you should not share water bottles, utensils, makeup, razors, etc., with others while having an active Herpes lesion.
