Herpes Simplex Virus: Why 7 Out of Every 10 Have It

In the health settings, we see patients almost daily with painful sores around the mouth (cold sores) or genitals. Many are worried, ashamed, or confused, often thinking it's something rare or "dirty." The truth is, herpes simplex virus (HSV) is one of the most common infections worldwide and in Nigeria. It's not a judgment; it's just a virus that spreads easily through close contact.
HSV comes in two main types:
- HSV-1: Usually causes oral herpes (cold sores around the mouth). It can also cause genital infections through oral sex.
- HSV-2: Mainly causes genital herpes, spread through sexual contact.
Both types can infect either area, and many people carry the virus without symptoms.
How Common Is HSV in Nigeria?
HSV is very widespread here. Studies show:
- About 74% of people have HSV-1 (often picked up in childhood through kissing or sharing items).
- HSV-2 affects around 13% overall, higher in some groups (e.g., up to 50-60% in certain populations like sex workers or pregnant women).
Most infections are asymptomatic or mild, so many don't know they have it. But when symptoms appear, they can be uncomfortable and recurring.

How Does HSV Spread?
HSV spreads through direct skin-to-skin contact with an infected area (even if no sores are visible, due to asymptomatic shedding). Common ways:
- Kissing or sharing drinks/utensils (HSV-1 oral).
- Sexual contact (vaginal, anal, or oral) (HSV-2 or HSV-1 genital).
- From mother to baby during delivery (rare but serious—can cause neonatal herpes).
It's not spread by toilet seats, swimming pools, or casual contact like hugging.
Common Symptoms
Symptoms usually appear 2–12 days after exposure (the first outbreak is often the worst). Many people have no or mild symptoms.
Oral herpes (HSV-1):
- Tingling/itching around lips/mouth.
- Painful blisters or cold sores that burst into ulcers, then crust over (last 7–10 days).
- Fever, sore throat, swollen glands (first time).
Genital herpes (HSV-2 or HSV-1):
- Painful blisters/ulcers on genitals, buttocks, thighs, or anus.
- Painful urination, discharge, swollen groin nodes.
- Flu-like symptoms (fever, body aches) in first outbreak.
Recurrent outbreaks are usually milder and shorter (4–7 days). Triggers include stress, illness, menstruation, or sun exposure.
Treatment
There's no cure (the virus stays dormant in nerves lifelong), but antivirals shorten outbreaks and reduce spread. Common options:
- Acyclovir (Zovirax): 400 mg orally 3 times/day for 7–10 days (first episode) or 5 days (recurrent).
- Valacyclovir (Valtrex): 1 g orally twice/day for 7–10 days (first) or 500 mg twice/day for 3 days (recurrent). Easier dosing.
- Famciclovir (Famvir): Similar regimens.
For frequent recurrences (>6/year), daily suppressive therapy (e.g., valacyclovir 500 mg once daily) cuts outbreaks by 70–80% and reduces transmission.
Topical creams (e.g., acyclovir cream) help mild oral sores but are less effective for genital sores. Pain relief: paracetamol, cool compresses, salt baths. Avoid irritants like tight clothes.
In pregnancy or severe cases (e.g., eye involvement), see a doctor immediately

Prevention – Simple Steps
- Avoid skin-to-skin contact during outbreaks (sores or prodrome tingling).
- Use condoms/dental dams (reduce but don't eliminate risk—virus sheds from uncovered skin).
- Don't kiss/share items during active cold sores.
- For genital: Suppress with daily antivirals if partner has HSV (cuts transmission ~50%).
- Get tested if at risk. Blood tests detect antibodies; swabs confirm active sores.
Myth bust: HSV isn't "only for promiscuous people." It's common and can happen to anyone. It's not a sign of uncleanliness.
Final Thoughts
HSV is common and lifelong but rarely dangerous for most people. With antivirals, outbreaks are shorter and less frequent, and transmission can be reduced. In Nigeria, stigma makes it hard to talk about it; let's change that. If you have sores, burning, or worry about exposure, don't self-diagnose or buy random creams. Come to a pharmacy or clinic for proper advice, testing, and treatment.
