Genital herpes is on the rise. Here’s what to know about this common infection

The World Health Organization (WHO) recently released new estimates suggesting around 846 million people aged between 15 and 49 live with a genital herpes infection.
That’s equivalent to one in every five people from that age group.
At least one person each second (42 million people annually) contracts a new genital herpes infection.
So what is genital herpes, and are cases on the rise? Here’s what to know about this common infection.
First, what causes genital herpes?
Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus, which also causes cold sores.
There are two types of herpes simplex virus, HSV-1 and HSV-2 (and it’s possible to be infected by both at the same time).
HSV-1 most commonly spreads through oral contact such as kissing or sharing infected objects such as lip balm, cups or utensils, and presents as cold sores (or oral herpes) around the mouth. But it can also be sexually transmitted to cause a genital herpes infection.
An estimated 3.8 billion people under the age of 50 (64%) globally have HSV-1.
HSV-2 is less prevalent, but almost always causes a genital herpes infection. Some 520 million people aged 15–49 (13%) worldwide are believed to have HSV-2.
The initial episode of genital herpes can be quite painful, with blisters, ulcers and peeling skin around the genitals over 7–10 days.
Not all people have severe (or any) initial symptoms. This means a person might not know they have been infected with a herpes virus.
Herpes is a lifelong infection, which means once you contract the virus, you have it forever. After an initial episode, subsequent episodes can occur, but are usually less painful or even symptom free.
Both oral and genital herpes are particularly easy to spread when you have active lesions (cold sores or genital ulcers). But even with no symptoms, herpes can still be spread to a partner.
And although relatively rare, oral herpes can be transmitted to the genital area, and genital herpes can be transmitted to the mouth through oral sex.
If an expectant mother exhibits a genital herpes infection close to childbirth, there are risks to the baby. A herpes infection can be very serious in a baby, and the younger the infant, the more vulnerable they are. This is also one reason why you should avoid kissing a baby on the mouth.
Changing trends
WHO’s recent figures brought together data from around the world to estimate the prevalence of genital herpes in 2020, compared with previous estimates in 2012 and 2016.
This data shows no significant difference in the prevalence of genital herpes caused by HSV-2 since 2016, but does highlight increases in genital herpes infections caused by HSV-1.
The estimated number of genital HSV-1 infections globally was nearly twice as high in 2020 compared with 2016 (376 million compared with 192 million).
A 2022 study looking at Australia, New Zealand and Canada found more than 60% of genital herpes infections are still caused by HSV-2. But this is declining by about 2% each year while new genital infections that result from HSV-1 are rising.
There’s no simple fix, but safe sex is important
Genital herpes causes a substantial disease burden and economic cost to health-care services.
With such a large proportion of the world’s population infected with HSV-1, evidence this virus is increasingly causing genital herpes is concerning.
There’s no cure for genital herpes, but some medications, such as antivirals, can help reduce the amount of virus present in the system. While this won’t kill it completely, it helps to prevent symptomatic genital herpes recurrences, improve quality of life, and minimise the risk of transmission.
To prevent the spread of genital herpes and other STIs, practise safe sex, particularly if you’re not sure of your partner’s sexual health. You need to use a barrier method such as condoms to protect against STIs (a contraceptive such as the pill won’t work). This includes during oral sex.
As herpes is now so common, testing is not usually included as part of a regular sexual health check-up, except for in specific circumstances such as during pregnancy or severe episodes.
So it’s wise not to let your guard down, even if your partner insists they have received the all-clear from a recent check-up.
If there are herpes lesions present around the genitals, avoid sex entirely. Even condoms are not fully effective at these times, as exposed areas can still transmit the infection.
Immune health
If you are infected with HSV-1 or HSV-2 it’s more likely symptoms will appear when you’re stressed, tired or overwhelmed. During these times, our immune system may not be as functional, and dormant viruses such as herpes can start to develop quickly in our bodies.
To reduce the risk of recurrent herpes infections, try to eat healthily, get at least seven hours of sleep each night if possible, and look out for when your body may be telling you to take a step back and relax. This self-care can go a long way towards keeping latent viruses at bay.
While the prevalence has increased significantly in recent years, we have not lost the war on genital herpes just yet. Safe sexual practices, education and awareness can help reduce its spread, and the stigma around it.
If you have personal concerns, you should discuss them with a medical professional.

Counterclockwise – by Dr. Ellen Langer
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’ve written previously about Dr. Langer’s famous “Counterclockwise” study that saw reversals in biological markers of aging after a one-week intervention that consisted only of a (albeit rather intensive) mental reframe with regard to their age.
This book, as you might expect from the title, refers to that experiment a lot—but it doesn’t stop there. While the Counterclockwise experiment remains Dr. Langer’s most well-known, it’s not her most recent, and she draws from a wealth of research (her own and that of her colleagues in the field) to show the extent and limit of psychosomatic effect on aging.
Note:
- psychosomatic effect does not mean: “imagining it”
- psychosomatic effect means: “your brain regulates almost everything else in your body, directly or indirectly, including your autonomic functions, which includes immune function, tissue replacement, and more”
And as for when it comes to aging? Aging, like cancer, is in large part a problem of immune dysfunction; in both cases cells (be they senescent or cancerous, respectively) are not being killed when they are supposed to be, and in both cases, better instructions will improve the matter.
Many larger-scale markers of aging, such as mobility, are a case of the body only being able to do what the tissues allow, and the tissues are being constantly rebuilt (for better or for worse) according to autonomically-implemented specifications, and cells’ ability to carry out those orders.
Beyond the cellular physiology, this book discusses (a lot) the brain-down mechanisms by which the most powerful organ in our body can tell the rest of the body how old to be.
Dr. Langer also discusses the matter of “priming”, that is to say, how external factors prime us to believe certain things about our age and, with it, our health. These things can include popular media, conversations with friends and family, and healthcare providers’ framing of certain issues.
For example, a person just under a certain age and a person just over a certain age could both go to the doctor with the same complaint—a pain in a certain joint, let’s say. The doctor may refer the slightly younger patient for an x-ray because “let’s see what’s going on here”, and prescribe the slightly older patient some painkillers because “this is perfectly normal at your age”. One resultant problem is obvious: a difference in the standard of care. But the other resultant problem is less obvious: the older patient has now been primed to believe, by a confident authority figure, “it is natural for my body to be in a state of decline now, and this is what to expect”.
Thus, Dr. Langer prescribes mindfulness, not in the mindfulness meditation sense (though sure, do that too), but rather in the sense of consciously interacting with the world and making our own decisions about our own health and, yes, our own age. Because after all, our body neither knows nor cares how many times it has flown around the sun, and merely responds to physiological stimuli—including those we can influence with psychological reframing.
The book is not, per se, a “how-to” guide, rather it is an explanatory treatise, but it contains more than enough information to put it into practice, and indeed, she does also provide some exercises to do along the way.
The style is… Vivacious, without being especially upbeat. Dr. Langer is enthused about her work, yes, but she’s also angry at how many people are having their health sabotaged on the daily, and calls for a more health-first approach (as opposed to illness-first).
Bottom line: this is the book on our brain’s power over aging, so if that topic interests you, this book absolutely belongs on your bookshelf. Well, in your hands, and then on the bookshelf, and then back in your hands from time to time.

New California Laws Target Medical Debt, AI Care Decisions, Detention Centers
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
SACRAMENTO, Calif. — As the nation braces for potential policy shifts under President-elect Donald Trump’s “Make America Healthy Again” mantra, the nation’s most populous state and largest health care market is preparing for a few changes of its own.
With supermajorities in both houses, Democrats in the California Legislature passed — and Democratic Gov. Gavin Newsom signed — laws taking effect this year that will erase medical debt from credit reports, allow public health officials to inspect immigrant detention centers, and require health insurance companies to cover fertility services such as in vitro fertilization.
Still, industry experts say it was a relatively quiet year for health policy in the Golden State, with more attention on a divisive presidential election and with several state legislators seeking to avoid controversial issues as they ran for Congress in competitive swing districts.
Newsom shot down some of legislators’ most ambitious health care policies, including proposals that would have regulated pharmaceutical industry middlemen and given the state more power to stop private equity deals in health care.
Health policy experts say advocates and legislators are now focused on how to defend progressive California policies such as sweeping abortion access in the state and health coverage for immigrants living in the U.S. without authorization.
“I think everyone’s just thinking about how we’re going to enter 2025,” said Rachel Linn Gish, a spokesperson with the consumer health advocacy group Health Access California. “We’re figuring out what is vulnerable, what we are exposed to on the federal side, and what do budget changes mean for our work. That’s kind of putting a cloud over everything.”
Here are some of the biggest new health care laws Californians should know about:
Medical debt
California becomes the eighth state in which medical debt will no longer affect patients’ credit reports or credit scores. SB 1061 bars health care providers and debt collectors from reporting unpaid medical bills to credit bureaus, a practice that supporters of the law say penalizes people for seeking critical care and can make it harder for patients to get a job, buy a car, or secure a mortgage.
Critics including the California Association of Collectors called the measure from Sen. Monique Limón (D-Santa Barbara) a “tremendous overreach” and successfully lobbied for amendments that limited the scope of the bill, including an exemption for any medical debt incurred on credit cards.
The Biden administration has finalized federal rules that would stop unpaid medical bills from affecting patients’ credit scores, but the fate of those changes remains unclear as Trump takes office.
Psychiatric hospital stays for violent offenders
Violent offenders with severe mental illness can now be held longer after a judge orders them released from a state mental hospital.
State officials and local law enforcement will now have 30 days to coordinate housing, medication, and behavioral health treatment for those parolees, giving them far more time than the five-day deadline previously in effect.
The bill drew overwhelming bipartisan support after a high-profile case in San Francisco in which a 61-year-old man was charged in the repeated stabbing of a bakery employee just days after his release from a state mental hospital. The bill’s author, Assembly member Matt Haney (D-San Francisco), called the previous five-day timeline “dangerously short.”
Cosmetics and ‘forever chemicals’
California was the first state to ban PFAS chemicals, also known as “forever chemicals,” in all cosmetics sold and manufactured within its borders. The synthetic compounds, found in everyday products including rain jackets, food packaging, lipstick, and shaving cream, have been linked to cancer, birth defects, and diminished immune function and have been increasingly detected in drinking water.
Industry representatives have argued that use of PFAS — perfluoroalkyl and polyfluoroalkyl substances — is critical in some products and that some can be safely used at certain levels.
Immigration detention facilities
After covid-19 outbreaks, contaminated water, and moldy food became the subjects of detainee complaints and lawsuits, state legislators gave local county health officials the authority to enter and inspect privately run immigrant detention centers. SB 1132, from Sen. María Elena Durazo (D-Los Angeles), gives public health officials the ability to evaluate whether privately run facilities are complying with state and local public health regulations regarding proper ventilation, basic mental and physical health care, and food safety.
Although the federal government regulates immigration, six federal detention centers in California are operated by the GEO Group. One of the country’s largest private prison contractors, GEO has faced a litany of complaints related to health and safety. Unlike public prisons and jails, which are inspected annually, these facilities would be inspected only as deemed necessary.
The contractor filed suit in October to stop implementation of the law, saying it unconstitutionally oversteps the federal government’s authority to regulate immigration detention centers. A hearing in the case is set for March 3, said Bethany Lesser, a spokesperson for California Attorney General Rob Bonta. The law took effect Jan. 1.
Doctors vs. insurance companies using AI
As major insurance companies increasingly use artificial intelligence as a tool to analyze patient claims and authorize some treatment, trade groups representing doctors are concerned that AI algorithms are driving an increase in denials for necessary care. Legislators unanimously agreed.
SB 1120 states that decisions about whether a treatment is medically necessary can be made only by licensed, qualified physicians or other health care providers who review a patient’s medical history and other records.
Sick leave and protected time off
Two new laws expand the circumstances under which California workers may use sick days and other leave. SB 1105 entitles farmworkers who work outdoors to take paid sick leave to avoid heat, smoke, or flooding when local or state officials declare an emergency.
AB 2499 expands the list of reasons employees may take paid sick days or use protected unpaid leave to include assisting a family member who is experiencing domestic violence or other violent crimes.
Prescription labels for the visually impaired
Starting this year, pharmacies will be required to provide drug labels and use instructions in Braille, large print, or audio for blind patients.
Advocates of the move said state law, which already required translated instructions in five languages for non-English speakers, has overlooked blind patients, making it difficult for them to monitor prescriptions and take the correct dosage.
Maternal mental health screenings
Health insurers will be required to bolster maternal mental health programs by mandating additional screenings to better detect perinatal depression, which affects 1 in 5 people who give birth in California, according to state data. Pregnant people will now undergo screenings at least once during pregnancy and then six weeks postpartum, with further screenings as providers deem necessary.
Penalties for threatening health care workers (abortion clinics)
With abortion care at the center of national policy fights, California is cracking down on those who threaten, post personal information about, or otherwise target providers or patients at clinics that perform abortions. Penalties for such behavior will increase under AB 2099, and offenders can face felony charges, up to three years in jail, and $50,000 in fines for repeat or violent offenses. Previously, state law classified many of those offenses as misdemeanors.
Insurance coverage for IVF
Starting in July, state-regulated health plans covering 50 employees or more would be required to cover fertility services under SB 729, passed and signed last year. Advocates have long fought for this benefit, which they say is essential care for many families who have trouble getting pregnant and would ensure LGBTQ+ couples aren’t required to pay more out-of-pocket costs than straight couples when starting a family.
In a signing statement, Newsom asked legislators to delay implementation of the law until 2026 as state officials consider whether to add infertility treatments to the list of benefits that insurance plans are required to cover.
It’s unclear whether legislators intend to address that this session, but a spokesperson for the governor said that Newsom “clearly stated his position on the need for an extension” and that he “will continue to work with the legislature” on the matter.
Plans under CalPERS, the California Public Employees’ Retirement System, would have to comply by July 2027.

Just One Thing – by Dr. Michael Mosley
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This is a collection of easy-to-implement changes that have good science behind them to show how they can benefit us. Some things are obvious (e.g: drink water); others, less so (e.g: sing, to reduce inflammation).
The book is divided thematically into times of the day, though in many cases it’s not a hard rule that a thing needs to be done at a certain time. Others are, like a cold shower in the morning and hot bath before bed—you might not want to switch those around!
The style is very pop-science, and does not have in-line citations for claims, but it does have a bibliography in the bag organized by each “one thing”, e.g. it might say “get some houseplants” and then list a number of references supporting that, with links to the studies showing how that helps. For those with the paper version, don’t worry, you can copy the URL from the book into your browser and see it that way. In any case, there are 2–6 scientific references for each claim, which is very respectable for a pop-sci book.
Bottom line: if you’re looking for evidence-based “one little thing” changes that can make a big difference, this book has lots!

Sleep Through Insomnia – by Dr. Brandon Peters
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
First, what this is not: a guide to get better sleep tonight.
Rather, what it is: a guide to get better sleep in the near future (six weeks).
The way it delivers this is primarily Cognitive Behavioral Therapy for Insomnia (CBT-I), in 6 weekly lessons, each divided into 3 activities:
- Reflection
- Education
- Setting goals
Now, all parts are important, but we’d say the biggest value here is in the education segment, in part because it helps the reader understand why the reflection is important, and how to usefully set the goals.
“Reflection” may sound quite wishy-washy, but in fact it is very science-based, with questions as prompts, which effectively amount to the “gathering data” part of science.
“Setting goals”, for its part, is intended to be a progressive, step-by-step approach to get you to where you want to be with your sleep.
The style is instructional pop-science, with everything made easy to understand. There are an abundance of scientific references for those who wish to delve further, and sometimes he does go into more neurological detail than a book written by a psychologist might (Dr. Peters being a medical doctor, board-certified in neurology and sleep medicine, and with extensive training in CBT-I).
Bottom line: if you’d like to sleep better and you have the will to commit to a 6-week program (which will not ask anything arduous of you, but you will need to show up for it and do the things), then this book can give you a much better long-term fix than telling you to change your sheets and put your phone away.

The Sugary Food That Lowers Blood Sugars
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Loved the article on goji berries! I read they are good for blood sugars, is that true despite the sugar content?❞
Most berries are! Fruits that are high in polyphenols (even if they’re high in sugar), like berries, have a considerable net positive impact on glycemic health:
- Polyphenols and Glycemic Control
- Polyphenols and their effects on diabetes management: A review
- Dietary polyphenols as antidiabetic agents: Advances and opportunities
And more specifically:
Dietary berries, insulin resistance and type 2 diabetes: an overview of human feeding trials
Read more: Which Sugars Are Healthier, And Which Are Just The Same?
As for goji berries specifically, they’re very high indeed in polyphenols, and also have a hypoglycemic effect, i.e., they lower blood sugar levels (and as a bonus, increases HDL (“good” cholesterol) levels too, but that’s not the topic here):
❝The results of our study indicated a remarkable protective effect of LBP in patients with type 2 diabetes. Serum glucose was found to be significantly decreased and insulinogenic index increased during OMTT after 3 months administration of LBP. LBP also increased HDL levels in patients with type 2 diabetes. It showed more obvious hypoglycemic efficacy for those people who did not take any hypoglycemic medicine compared to patients taking hypoglycemic medicines. This study showed LBP to be a good potential treatment aided-agent for type 2 diabetes.❞
- LBP = Lycium barbarum polysaccharide, i.e. polysaccharide in/from goji berries
- OMTT = Oral metabolic tolerance test, a test of how well the blood sugars avoid spiking after a meal
