The Blood Tests Do Have A Lot Of Value But Here Are The Biggest Issues:
About 50% of the population has type 1 herpes. Type 1 can be genital or oral. If you have never had symptoms and obtain an IgG based type-specific blood test , and the test comes back positive for type 1, we have no way of knowing whether you are infected orally, genitally, or both. The only way we can know which location is infected is by symptoms.
About 30% of negative results for HSV 1 are false negatives. This means if you test negative, you might still have HSV 1.
If you are positive for type 2 and fall within a positive range of 1.1 3.5, theres a decent chance this is a false positive. About 50% of positives that fall in this range are in error, with the closer you get to 3.5 the more likely you are positive and the closer to 1.1 the less likely you are positive. There can be false positives above 3.5 as well but theyre less likely. If you do test positive within this low range, the CDC recommends confirmatory testing. The most accurate confirmatory blood test is the Western Blot. The Western Blot is more complicated to obtain and your insurance may not cover it. In addition, many doctors do not know about the high false positive rate within this range so they incorrectly diagnose their patients without getting confirmation. I have worked with a number of patients diagnosed within this range who I encouraged to follow up with the Western Blot and they discovered they were negative.
Blood tests given too early after possible exposure can be false negative.
How To Prevent The Spread Of Herpes
Although herpes is a lifelong virus that cant be cured, it goes through periods of dormancy between outbreaks. This means that while the virus is still present, its not actively replicating.
During this time, you may not experience any signs or symptoms of having the disease even if youve had a previous outbreak before.
However, you can still spread the herpes virus to your sexual partners at any time, even if no sores are present. In addition, although rare, its possible to spread oral herpes to the genital region and vice versa.
For this reason, its extremely important to be mindful of the following preventive measures:
- Tell your partners that you have genital or oral herpes. This allows them to make informed decisions about their own sexual health, and its the responsible thing to do.
- If youre experiencing the signs and symptoms of an upcoming outbreak, avoid all sexual contact. Youre most likely to spread the virus to others during an outbreak.
- Its possible to spread the herpes virus even without an outbreak. If youre worried about spreading the disease to a partner, research shows that antivirals are effective at reducing this possibility.
Having oral or genital herpes doesnt mean that you can no longer have sex. However, its your responsibility to prevent the spread of herpes to your sexual partner.
If you have herpes, you can still take care of your sexual health through open communication and safer sex.
What Are The Signs Of Herpes In Men
In about two-thirds of cases, men will have no symptoms of herpes. Symptoms of herpes in men may include:
It is unclear if genital herpes affects fertility in men because it affects such a large part of the population. However, a recent study found that herpes may lower the sperm count in men and may have an effect on menâs ability to get pregnant with a partner.

Herpes Causes And Risk Factors
Causes of herpes include acquiring the virus through sexual contact, coupled with immune system suppression and sometimes nutritional deficiencies.
HSV-1 is primarily transmitted by oral-oral contact. On the other hand, HSV-2 is considered a sexually transmitted disease and usually passed during oral or vaginal sex.
A scary finding is that more cases of genital herpes than ever before are now being caused by HSV-1 , and about 85 percent of people with genital herpes dont even know it. Studies show that about 50 percent of the new genital herpes infections in young adults are due to HSV-1 and about 40 percent in older adults. The fact that most people dont ever find out theyre infected is one of the reasons that transmission rates are steadily climbing.
Risk factors for acquiring herpes include:

It is likely that your health insurance company will provide STD testing in many cases. If you are unsure about the results of the test, you should consult with your health insurance company. In addition to choosing the right STD testing facility, you can also consult the urgent care center where you are completing your test.

Although it may not feel this way, the doctors and researchers who established these guidelines have been quite thoughtful about them. If you read the documents, you can see that the researchers sensitively consider their decision from many different angles. In fact, you can learn a ton about the research on genital herpes and transmission where they discuss the reasoning for their decision.
The biggest contributing factor to the guidelines is that 1) standard herpes blood tests are not totally reliable and 2) receiving a herpes diagnosis can have a significant impact on mental health while being virtually non-threatening to your physical health.
What Is The Usual Treatment For Genital Herpes
The doctor may prescribe antiviral tablets to speed up healing and reduce the severity of a first episode. Aciclovir is the most commonly used antiviral drug for treating genital herpes. You dont need the tablets if the first episode is mild, or if you have almost recovered before you see the doctor.If you get more episodes later on, you will be less likely to be offered with antiviral tablets as outbreaks clear up without treatment.To prevent a recurrent outbreak with antiviral tablets, you need to start taking them within 24 hours of noticing the beginning of the outbreak. When you start after 24 hours, it is unlikely that the tablets will have much effect. This is why you should have a prescription or tablets ready, so that you can start to take them as soon as possible see dosing information below.

Genital Herpes Is Common Shouldnt Cdc Recommend Testing For Everyone
CDC recommends herpes testing for people who have genital symptoms to confirm if they have it. Testing allows a healthcare provider to talk with patients about what to expect in the future. This includes talking about medications that help with symptoms. Providers can also tell patients how to lower the risk of transmitting herpes to sex partner.
CDC does not recommend herpes testing for people without symptoms in most situations. This is because of the limits of a herpes blood test and the possibility of a wrong test result. The chances of wrong test results are higher for people who are at low risk of infection.
Blood tests might be useful if:
- You have genital symptoms that could be related to herpes, or
- You have a sex partner with genital herpes, or
- Your provider found signs of herpes, but you still need a test to confirm it.
If you are sexually active, talk openly and honestly with your healthcare provider about what tests are right for you. These tips can help.

What Happens During A Herpes Test
If you have blisters or sores, your doctor or nurse will gently take a sample of fluid from the sores with a swab and test it.
If you dont have any sores, talk with your doctor or nurse about whether a blood test for herpes makes sense for you. But herpes tests aren’t normally recommended unless you do have symptoms.
The idea of getting tested may seem scary, but try to chill out. STD testing is a regular part of being a responsible adult and taking care of your health. And herpes tests are quick and usually painless.
Tmrca Inference For Other Primate Simplex Viruses
We also investigated whether BSREL provided consistent tMRCA estimates for the MHV-1. Divergence times within Macaca have been well characterized. The three host species whose viruses were included here share an MRCA around 2.22.5 Ma . The tMRCA for all three viral lineages estimated using BSREL branch lengths, 2.1 Ma, was closer to the host tMRCA, compared with branch lengths inferred under GTR + 4, which yielded an older tMRCA, 3.7 Ma . The same pattern holds for the M. fuscata and M. mullata tMRCA around 1.7 Ma . The BSREL analysis estimated a viral tMRCA at 2.0 Ma, whereas the GTR + 4 placed the tMRCA at 3.3 Ma . Therefore, BSREL provides more internally consistent tMRCAs than the GTR + 4 model and supports a general pattern of codivergence throughout the primate simplex viruses.
An exception to this general pattern of codivergence is found by examining the tMRCA of CeHV-2 and HVP-2. Both substitution models indicate that this tMRCA is too recent to be the result of codivergence with Chlorocebus pygerythrus and Papio spp. around 11.6 Ma . The genus Papio started diverging around 2 Ma . Therefore, the CeHV-2/HVP-2 tMRCA inferred with BSREL branch lengths of 1.9 Ma confirms that CeHV-2 is, evolutionarily, a baboon virus, as has been suggested previously .
What You Need To Know About Herpes And How Its Transmitted
Two versions of the herpes simplex virus can cause this infection, according to the Centers for Disease Control and Prevention : herpes simplex virus type 1 and herpes simplex virus type 2 .
You might be thinking, Oooh, wait, HSV-1 causes oral herpes, and HSV-2 causes genital herpes, right? Technically, yes. But thats not the full picture. Both viruses can infect either your mouth or your genitals through skin-to-skin contact, the CDC explains.
HSV-1 has a predilection for the oral mucosa, but cases affecting the genitals are rising, Susan Bard, M.D., a New York City board-certified dermatologist and adjunct clinical instructor at the Mount Sinai Hospital, tells SELF. This can happen if, say, a person with HSV-1 in their mouth passes the infection to someones genitals while performing oral sex. And although HSV-2 is still behind most cases of genital herpes, it can cause oral herpes when someone with this infection on their genitals passes it to another persons mouth during oral sex.
You might think these signs would make it really obvious that something is up with your health if you have herpes. But its also entirely possible to have herpes without exhibiting any symptoms at all. The virus can lie dormant in the body without ever making itself known. Thats why so many people have herpes without realizing it, the CDC explains.
How Long Does It Take For Symptoms Of Herpes To Appear
The primary symptom of a herpes outbreak is sores that resemble blisters, called herpes lesions, on the mouth or genitals.
In addition, people may also experience the following symptoms prior to the outbreak:
- pain and redness, especially around the area the outbreak will occur
- itching and tingling, primarily in the outbreak area
- flu-like symptoms, such as fatigue, fever, or swollen lymph nodes
Most of the symptoms that occur before an outbreak indicate that the virus is replicating. Symptoms are usually the worst during the first herpes outbreak.
According to the
Some people with the herpes virus are asymptomatic, which means that they dont experience any physical symptoms of the disease. This doesnt mean that they cant spread the disease, however.
Anyone who has the herpes virus, whether symptomatic or not, can spread the virus to others.
If you have the herpes virus and your body has produced antibodies, it can be detected on a blood test, even if you have no symptoms. The only time the virus might not be detected on a test is if youve been tested too early.

What Happens Once You Have Hsv
Once a person becomes infected with a herpes virus, the virus never leaves the body. After the first outbreak, the virus moves from the skin cells to nerve cells. The virus stays in the nerve cells forever. But it usually just stays there. In this stage, the virus is said to be dormant, or asleep. But it can become active again.
Some things that can trigger the virus are:
Are There Other Types Of Herpes Viruses Besides Hsv
Yes. There are over 25 viruses in the herpes family and at least 8 types that infect humans. These include herpes simplex virus types 1 and 2 discussed in this article as well as varicella zoster virus , associated with chickenpox and shingles, Epstein Barr virus , which can cause infectious mononucleosis, cytomegalovirus , human herpes virus 6 and human herpes virus 7 , both associated with roseola in young children, and human herpes virus 8 , which has been found in tumors in people with Kaposi’s sarcoma . KS primarily affects people with weakened immune systems, such as those with HIV/AIDS and organ transplant recipients.

What Is The Long
People who contract HSV will have the virus for the rest of their lives. Even if it does not manifest symptoms, the virus will continue to live in nerve cells.
Some people may experience regular outbreaks. Others will only experience one outbreak after they contract the virus, and then the virus may become dormant. Even if a virus is dormant, certain stimuli can trigger an outbreak. These include:
When Should I Get A Genital Or Oral Herpes Test
Testing for the viruses that cause genital and oral herpes may be ordered when a patient develops signs and symptoms of a herpes infection. Although many people who contract HSV never notice symptoms, signs of an initial infection appear 2 to 20 days after infection and depend on the type of HSV causing the infection.
When signs and symptoms of an initial infection occur, they may include:
- Small sores on the skin
- Tingling, itching, or burning on the skin
- Fever, headache, or body aches
- Swollen lymph nodes
After the initial infection, HSV remains dormant inside of the body. HSV can reactivate throughout a patients life, causing symptoms of genital or oral herpes to reappear. While the trigger for an HSV outbreak is often unknown, potential triggers include a fever, stress, physical trauma, and a suppressed immune system.
Generally, expert organizations do not recommend herpes testing for patients without symptoms. An exception may be made for certain patients, including:
- Patients who have a partner with genital herpes
- Patients seeking a more complete STD test panel, including people with multiple sexual partners
- Babies born to a mother who has HSV

The only major difference, of course, is where you experience symptoms:
- If HSV affects your genitals, you might notice pain or burning during urination.
- If HSV affects your mouth, you might have difficulty eating spicy or acidic foods while you have open sores.

I Had Lesions When I Was Evaluated But My Culture Was Negative Does This Mean That I Dont Have Herpes
Not necessarily. Although lesions can be caused by something other than herpes, false negative herpes tests can occur if the samples are not taken appropriately, if there is a long transport time between the clinic and the laboratory, or if cultures were taken late in the course of the lesions. Lesions that occur early in the course of a herpes outbreak are much more likely to have positive cultures than cultures taken after the lesions crust over.
