Generally, speaking about sexually transmitted diseases (STIs) is sort of a mood-killer. However, the term"herpes" in particular invokes a unique type of dread and paranoia. Although genital herpes is quite common (it's the 5th most frequent STI in Singapore). But, is there a treatment for herpes?
But is there no vaccine or cure for a number of their most feared (and frequent ) STIs? And have we gotten any closer to finding one?
Here is what we found after chatting with experts.
What's herpes?
Oral is caused by herpes simplex virus 1 (HSV-1), and is the virus which causes cold sores. People with oral herpes normally get the virus as children by kissing relatives or friends.
By comparison, genital herpes is brought on by the herpes simplex virus type two (HSV-2), which is normally transmitted via rectal, anal, or oral intercourse. HSV-2 has symptoms like an outbreak of blisters on the genitals or rectum, but a lot of folks can also be curable. Genital herpes may also be caused by HSV-1 during oral sex.
Why are there no treatment for herpes?
Presently, there's no cure for either HSV-1 or even HSV-2, though individuals with both types of herpes can take antiviral medications like Valtrex to control their symptoms and lower their risk of transmitting the virus to their partners.
For the past 80 decades, yet, scientists are researching potential herpes outbreaks. (Note: Although"treatment" and"vaccine" can be used interchangeably, they are not similar. In the case of herpes, a treatment would completely eliminate the herpes virus in the human body, though a vaccine would cure or stop it.)
So far, scientists have tried to develop two types of herpes meds: a preventative one, which protects you from getting infected in the first place; and a therapeutic one, that would help manage symptoms in people who have the disease and lessen the risk of outbreaks better than current antifungal drugs on the industry. Yet they've had little luck.
The herpes virus can be extremely complex
"We don't have a cure for a great deal of items," she says, mentioning HIV and hepatitis along with other cases.
Most viruses attack our cells and try to multiply once they enter our bodies. In conclusion our immune system releases dead cells and antibodies to neutralize the virus and make it less dangerous. Often, our immune systems can clean viruses from our own bodies, meaning we're not infected.
But herpes is more complicated than this, '' says Wald. Herpes"has figured out how to reside from the host regardless of the immune reaction," she explains.
To make things even more complex, the virus may lie dormant at our central nervous systems for a protracted period of time (this explains why people with herpes may go a few months with no flare-ups following a first outbreak, or have no signs at all).
The simple fact that our immune systems don't find out how to protect us from herpes makes it extremely difficult for scientists to produce a preventive vaccine. "It's rather tricky to make a vaccine if you don't know what type of immune response you are attempting to make to protect somebody," Wald says. Contrary to other viruses like the human papillomavirus (HPV), for instance, researchers cannot inject a portion of the herpes virus into our bodies because of vaccine, making them develop a antibody that fights back and prevents infection.
As for therapeutic vaccines, they'd have to be substantially better compared to current antiviral medications are at reducing the odds of outbreaks and transmission, says Dr. Hunter Hansfield, Professor Emeritus of Medicine, University of Washington Center for AIDS and STDs. Luckily, current antifungal drugs can already reduce the recurrence of outbreaks by roughly 70 per cent, based on American Family Physician.
How near are we to a successful herpes vaccine?
In 2016, it seemed like we had been on the cusp of a herpes vaccine when the bioscience company Genocea announced that it had finished phase two clinical trials for a therapeutic vaccine named GEN-003. Research showed that herpes sufferers were 65 percent less likely to have outbreaks after getting the vaccine and were 60 percent less likely to transmit the virus to their spouses.
But absence of funding killed the undertaking, a company spokesperson clarified to MensHealth.com. In September 2017, the business stopped growth of GEN-003 since they did not have enough cash to pay for phase 3 clinical trials, that might have been needed to be approved by the Food and Drug Administration (FDA). The company is presently focusing mostly on cancer research.
Can we get a herpes disorder?
Not for a long time, at least: at the present time, there are no promising clinical trials underway for a herpes vaccine.
Hansfield believes it's unlikely that investigators could soon develop into a herpes vaccine that would completely eliminate the virus from a person's system.
As for a preventative vaccine,"I would be surprised if there had been a HSV vaccine available on the market which prevents herpes in under 10 years," he says.
How to Safeguard Yourself from herpes
Aside from not having sex, there's no 100% effective way to avoid herpes. You can cut the danger of contracting the disease using a condom, however even a condom is not foolproof, as the virus can be transmitted even if your partner has no visible sores.
Having said that, if your partner has herpes, then taking antifungal drugs can significantly lessen the chances of transmission.
If you exhibit any of the symptoms of genital herpes, for example cracked, or red sores around your genitals or rectum, ask your doctor for a blood test to detect HSV antibodies. Even if you test negative, routine STI screening is very important to anybody who is sexually active, and free and affordable testing tools can be found on the CDC's web site.
