Here we are, well into year three of the COVID-19 pandemic, and now we’re having an outbreak of monkeypox? Is this a new virus? How worried should we be? While new information will continue to come in, here are answers to several common questions.

What is monkeypox?

Monkeypox is an infection caused by a virus in the same family as smallpox. It causes a similar (though usually less severe) illness and is most common in central and western Africa. It was first discovered in research monkeys more than half a century ago. Certain squirrels and rats found in Africa are among other animals that harbor this virus.

Currently, an outbreak is spreading fast outside of Africa. The virus has been reported in at least a dozen countries, including the US, Canada, Israel, and in Europe. As of this writing, Reuters reports more than 100 confirmed or suspected cases, making this the largest known outbreak outside of Africa. So far, no deaths have been reported.

Naturally, news about an unfamiliar virus spreading quickly internationally reminds us of the start of the COVID-19 pandemic. But monkeypox is not new — it was first discovered in 1958 — and several features make it likely to be far less dangerous.

What are the symptoms of monkeypox?

The early symptoms of monkeypox are flulike, and include

• fever
• fatigue
• headache
• enlarged lymph nodes.

The rash that appears a few days later is unique. It often starts on the face and then appears on the palms, arms, legs, and other parts of the body. Some recent cases began with a rash on the genitals. Over a week or two, the rash changes from small, flat spots to tiny blisters (vesicles) similar to chickenpox, and then to larger, pus-filled blisters. These can take several weeks to scab over. Once that happens, the person is no longer contagious.

Although the disease is usually mild, complications can include pneumonia, vision loss due to eye infection, and sepsis, a life-threatening infection.

How does a person get monkeypox?

Typically, this illness occurs in people who have had contact with infected animals. It may follow a bite or scratch, or consuming undercooked animal meat.

The virus can spread between people in three ways:

• inhaling respiratory droplets
• directly touching the blistering rash, scabs, or other body fluids of infected person
• less often, through indirect contact such as handling an infected person’s clothing.

The respiratory route involves large droplets that don’t linger in the air or travel far. As a result, person-to-person spread typically requires prolonged, intimate contact.

Is monkeypox a sexually transmitted illness?

Monkeypox is not considered a sexually transmitted illness (STI) because it can be spread through any physical contact, not just through sexual contact. Some of the recent cases have occurred among men who have sex with men. That pattern hasn’t been reported before.

Can monkeypox be treated?

Yes. Although there are no specific, FDA-approved treatments for monkeypox, several antiviral medicines may be effective. Examples are cidofovir, brincidofovir, and tecovirimat.

Can monkeypox be prevented?

Vaccination can help prevent this illness:

• Smallpox vaccination, which was routine in the US until the 1970s, may be up to 85% effective against monkeypox.. The US government has stockpiled doses of smallpox vaccine that could be used in the event of a widespread outbreak.
• Additionally, the FDA approved a vaccine (called JYNNEOS) in 2019 for people over 18 who are at high risk for smallpox or monkeypox. The makers of this vaccine are ramping up production as this outbreak unfolds.

If you are caring for someone who has monkeypox, taking these steps may help protect you from the virus: wear a mask and gloves; regularly wash your hands; and practice physical distancing when possible. Ideally, a caregiver should be previously vaccinated against smallpox.

How sick are most people who get monkeypox?

Monkeypox is usually a mild illness that gets better on its own over a number of weeks.

Researchers have found that the West African strain of monkeypox is responsible for the current outbreak. That’s good news, because the death rate from this strain is much lower than the Congo Basin strain (about 1% to 3% versus 10%). More severe illness may occur in children, pregnant people, or people with immune suppression.

What else is unusual about this outbreak?

Many of those who are sick have not traveled to or from places where this virus is usually found, and have had no known contact with infected animals. In addition, there seems to be more person-to-person spread than in past outbreaks.

Is there any good news about monkeypox?

Yes. Monkeypox usually is contagious after symptoms begin, which can help limit its spread. One reason COVID-19 spread so rapidly was that people could spread it before they knew they had it.

Outbreaks occur sporadically, and tend to be relatively small because the virus does not spread easily between people. The last US outbreak was in 2003; according to the CDC, nearly 50 people in the Midwest became ill after contact with pet prairie dogs that had been boarded near animals imported from Ghana.

Perhaps the best news is this: unlike SARS-CoV2, the virus that causes COVID-19, monkeypox is unlikely to cause a pandemic. It doesn’t spread as easily, and by the time a person is contagious they usually know they’re sick.

How worried should we be?

The growing numbers of cases in multiple countries suggest community spread is underway. More cases will probably be detected in the coming days and weeks.

It’s still early in the outbreak and there are many unanswered questions, including:

• Has the monkeypox virus mutated to allow easier spread? Early research is reassuring.
• Who is most at risk?
• Will illness be more severe than in past outbreaks?
• Will existing antiviral drugs and vaccines be effective against this virus?
• What measures can we take to contain this outbreak?

So, monkeypox is no joke and researchers are hard at work to answer these questions. Stay tuned as we learn more. And let your doctor know if you have an unexplained rash or other symptoms of monkeypox, especially if you have traveled to places where cases are now being reported.

You may have noticed nipped-in, hourglass waists among women wearing the celebrity trend du jour: so-called waist trainers. This tummy-tucking shapewear evokes images of buttoned-up corsets and too-tight girdles from a dim past. But does it live up to the hype?

Splashy advertisements suggest these compression devices can help you selectively sculpt inches off your waistline by wearing them during workouts or as part of everyday routines. But the claims largely don’t live up to the evidence, says Michael Clem, a physical therapist with Spaulding Rehabilitation Network.

“People want the quick fix,” Clem says. “Putting something around our waist seems easy — we do it every day with pants and belts. What’s one more thing? Diet and exercise take longer and require more dramatic habit changes. We all know what we need to do, we just don’t want to do it.”

Debunking the hourglass hype

Clem debunks four common claims made about waist trainers — and points out one case where they may prove useful.

• Spot-reduce fat: Compressing fat with a waist trainer and expecting it to stay put once you uncinch the shapewear is a faulty concept. “Fat is a systemic deposit,” Clem says. “Putting something around your waist can’t help you burn the fat in just that place.”
• Sweat away the inches: Similarly, perspiring more profusely in one body area — in this case, under your waist trainer — will not melt fat there. “Sweat is a mechanism for cooling the body. We expend calories when we sweat but we can’t say those calories are going to come from the area we sweat from,” Clem notes.
• Eat less due to belly compression: While orthopedic braces or compression sleeves can heighten awareness of a body part, leading wearers to act differently, the same probably can’t be said of a thick band around the belly. Our awareness of internal organs isn’t as strong, Clem says. And while waist trainers apply pressure to the abdomen, they probably wouldn’t alter the body’s feeling of being full.
• Build a stronger core: Wearing a waist trainer might help if a doctor recommends temporary use after certain surgeries — such as while someone is rebuilding core muscles after a cesarean section, hernia surgery, or appendectomy — by offering tangible “feedback” on abdominal muscle use as a person recovers. “But there are much better ways to teach someone to feel their core,” says Clem, including working with a physical therapist on posture and breathing.

In most cases, there’s probably no harm in trying one of the shape-shifting devices, although anyone who is pregnant should not use them. And if you have any health issues, it’s best to talk to your doctor about whether compressing your core could have any negative effects, including not being able to breathe deeply and comfortably.

Want to shape your waist? Try core strengthening exercises

Listed from least to most challenging, here are three great exercises to strengthen core muscles that help define the waist. Start with one set and work up, paying attention to your form.

Bridge

Reps: 10
Sets: 1–3
Tempo: 3–1–3
Rest: 30–90 seconds between sets

Starting position: Lie on your back with your knees bent and feet flat on the floor, hip-width apart. Place your arms at your sides. Relax your shoulders against the floor.

Movement: Tighten your buttocks, then lift your hips up off the floor until they form a straight line with your knees and shoulders. Hold. Return to the starting position.

Tips and techniques:

• Tighten your buttocks before lifting.
• Keep your shoulders, hips, knees, and feet evenly aligned.
• Keep your shoulders down and relaxed into the floor.

Opposite arm and leg raise

Reps: 10
Sets: 1–3
Tempo: 3–1–3
Rest: 30–90 seconds between sets

Starting position: Kneel on all fours with your hands and knees directly aligned under your shoulders and hips. Keep your head and spine neutral.

Movement: Extend your left leg off the floor behind you while reaching out in front of you with your right arm. Keeping your hips and shoulders squared, try to bring that leg and arm parallel to the floor. Hold. Return to the starting position, then repeat with your right leg and left arm. This is one rep.

Tips and techniques:

• Keep your shoulders and hips squared to maintain alignment throughout.
• Keep your head and spine neutral.
• Think of pulling your hand and leg in opposite directions, lengthening your torso.

Stationary Lunge

 

Reps: 8-12 on each side
Sets: 1-3
Tempo: 3-1-3
Rest: 30-90 seconds between sets

Starting position: Stand up straight with your right foot one to two feet in front of your left foot, hands on your hips. Shift your weight forward and lift your left heel off the floor.

Movement: Bend your knees and lower your torso straight down until your right thigh is about parallel to the floor. Hold, then return to starting position. Finish all reps, then repeat with your left foot forward. This completes one set.

Tips and techniques:

• Keep your front knee directly over your ankle.
• In the lunge position, shoulder, hip, and rear knee should be aligned. Don’t lean forward or back.
• Keep your spine neutral and your shoulders down and back.

Growing evidence suggests that poor sleep is linked to a host of health problems, including a higher risk of high blood pressure, diabetes, obesity, and heart disease. Now, a recent study on people in midlife finds that having a combination of sleep problems — such as trouble falling asleep, waking up in the wee hours, or sleeping less than six hours a night — may nearly triple a person’s risk of heart disease.

"These new findings highlight the importance of getting sufficient sleep," says sleep specialist Dr. Lawrence Epstein, assistant professor of medicine at Harvard Medical School. Many things can contribute to a sleep shortfall, he adds. Some people simply don’t set aside enough time to sleep. Others have habits that disrupt or interfere with sleep. And some people have a medical condition or a sleep disorder that disrupts the quality or quantity of their sleep.

Who was in the study?

The researchers drew data from 7,483 adults in the Midlife in the United States Study who reported information about their sleep habits and heart disease history. A subset of the participants (663 people) also used a wrist-worn device that recorded their sleep activity (actigraphy). Slightly more than half of participants were women. Three-quarters reported their race as white and 16% as Black. The average age was 53.

Researchers chose to focus on people during midlife, because that’s when adults usually experience diverse and stressful life experiences in both their work and family life. It’s also when clogged heart arteries or atherosclerosis (an early sign of heart disease) and age-related sleep issues start to show up.

How did researchers assess sleep issues?

Sleep health was measured using a composite of multiple aspects of sleep, including

• regularity (whether participants slept longer on work days versus nonwork days)
• satisfaction (whether they had trouble falling asleep; woke up in the night or early morning and couldn’t get back to sleep; or felt sleepy during the day)
• alertness (how often they napped for more than five minutes)
• efficiency (how long it took them to fall asleep at bedtime)
• duration (how many hours they typically slept each night).

To assess heart-related problems, researchers asked participants "Have you ever had heart trouble suspected or confirmed by a doctor?" and "Have you ever had a severe pain across the front of your chest lasting half an hour or more?"

A "yes" answer to either question prompted follow-up questions about the diagnosis, which included problems such as angina (chest pain due to lack of blood flow to the heart muscle), heart attack, heart valve disease, an irregular or fast heartbeat, and heart failure.

Poor sleep linked to higher heart risk

The researchers controlled for factors that might affect the results, including a family history of heart disease, smoking, physical activity, as well as sex and race. They found that each additional increase in self-reported sleep problems was linked to a 54% increased risk of heart disease compared to people with normal sleep patterns. However, the increase in risk was much higher — 141% — among people providing both self-reported and wrist-worn device actigraphy data, which together are considered more accurate.

Although women reported more sleep problems, men were more likely to suffer from heart disease. But overall, sex did not affect the correlations between sleep and heart health.

Black participants had more sleep and heart-related problems than white participants, but in general, the relationship between the two issues did not differ by race.

What does this mean for you?

If you have trouble falling or staying asleep, there are many ways to treat these common problems, from simple tweaks to your daily routine to specialized cognitive behavioral therapy that targets sleep issues. These are well worth trying, because getting a good night’s sleep helps in many ways.

"Treating sleep disorders that interfere with sleep can make you feel more alert during the day, improve your quality of life, and reduce the health risks related to poor sleep," says Dr. Epstein.

Inflammatory bowel disease (IBD) is commonly diagnosed when people are in their 20s and 30s, which is also when many people are planning families. Many people who have been diagnosed with IBD (which includes Crohn’s disease and ulcerative colitis) have questions and concerns regarding their fertility, conception, pregnancy, delivery, and breastfeeding.

Thinking about conceiving a child or becoming pregnant?

It is important to make sure that your IBD is well controlled, ideally before you begin trying to have a biological child. This is equally important for patients with male and female reproductive anatomy.

Patients with female reproductive anatomy who conceive in remission tend to remain in remission throughout their pregnancy. Research shows that poorly controlled IBD can lead to decreased fertility, and pregnancy can be complicated by premature loss, preterm labor, low birthweight, and small for gestational age babies.

You may require blood work, imaging, or endoscopy prior to conception to get an idea of whether you have an actively inflamed bowel before pregnancy. Your doctor may also modify your medications to ensure that your disease is as well controlled as possible.

You will require care from different types of health care providers during pregnancy, in addition to a gastroenterologist with expertise in IBD. Depending on the history and severity of your IBD, you may benefit from having a high-risk maternal fetal OB/GYN, colorectal surgeon, pharmacist, IBD nurse, psychologist, or nutritionist as part of your care team.

What should I do before I start trying to conceive or become pregnant?

It is recommended to take a prenatal vitamin and/or folic acid supplement. Vitamin D deficiency is common in IBD, and if your levels are low your doctor may recommend supplementation. It is also important to be up to date on your vaccines and review your medication list with your doctor.

Will I need to change my treatment before conception or pregnancy?

Many IBD medications have favorable safety profiles during conception and pregnancy. However, there are some medications that may impact fertility (such as by decreasing sperm count) or that may be unsafe to continue during pregnancy. For example, it is generally recommended to stop taking the drug methotrexate three months before conception.

As newer drugs are developed, research about the safety of IBD treatments continues. It is important to discuss your medications and any concerns you may have during the pregnancy planning period.

How will I be monitored during pregnancy?

Your gastroenterologist will carefully monitor your symptoms during preconception, pregnancy, and postpartum. You may be asked to provide stool samples to assess fecal calprotectin levels (a marker of inflammation measured in the stool), which can help your doctor monitor IBD activity prior to conception and during each trimester of your pregnancy.

Drug levels of certain IBD medications may be monitored via blood work as well, to ensure proper medication dosing. Monitoring and managing IBD throughout pregnancy is individualized for each patient, and the goal is to increase the chances of a healthy outcome for both you and your baby.

What if I have an IBD flare while pregnant?

During an IBD flare in pregnancy, the goal is to rapidly decrease inflammation and optimize an IBD treatment regimen in order to avoid complications for you and your and baby. This may involve drug level monitoring, adjusting medication dosage, or switching medication types. A short course of steroid medications may be needed in certain cases.

If your blood work indicates iron deficiency anemia (which can be caused by inflammation in the GI tract, but can also occur in pregnancy due to increased iron requirement for the baby), iron supplements, either oral or intravenous, can be used to improve blood counts.

What are my options for delivery?

Most people with IBD can deliver via their preferred method. The decision to have a vaginal or cesarean section delivery sometimes depends on a patient’s medical history. If a patient has Crohn’s disease and active perianal disease, a cesarean section may be recommended. This is because active perianal disease increases the risk of severe tears and trauma to the perineal area (area around the anus and vagina).

Patients with a history of steroid exposure and bone complications (like osteoporosis) may want to avoiding pushing during a vaginal delivery. A cesarean section may also be recommended if there are significant risk factors for injury to the perineal area, or an obstetric complication unrelated to Crohn’s or ulcerative colitis.

What happens after I give birth?

After delivery, it’s important to continue IBD medications. Approximately one-third patients will have an IBD flare within a year following delivery. Patients with poorly controlled IBD during the third trimester or while in de-escalation of therapy (reduction in medications) during or after pregnancy are at the highest risk for a postpartum flare. For this reason, it is important to maintain close follow-up with your IBD doctor during this time.

Can I breastfeed/chestfeed?

Breastfeeding/chestfeeding has many benefits for both the postpartum person and infant. Many IBD treatments have favorable safety profiles for breastfeeding/chestfeeding. Some newer biologic medications have not yet been studied well. Your doctor will discuss the risks and benefits of your individualized IBD treatment to ensure your regimen and breastfeeding goals are both optimized.

Will my baby have IBD?

While there is a genetic component to IBD, there is usually a low risk of IBD for biologic children of IBD patients. First-degree relatives (and in particular, siblings) of people with IBD do have an increased risk of Crohn’s disease and ulcerative colitis.

The bottom line

It is important to discuss family planning goals with your doctors early, so they can help you optimize your health and focus on achieving remission prior to conception. Fortunately, many IBD medications are considered safe and effective during conception, pregnancy, and postpartum. During pregnancy, proactive monitoring and early treatment of flares is essential. Every pregnancy is different, and close communication with your medical team is important to keep you and your developing baby healthy.
