If you’re planning an escape from the dreary winter weather, and you’re pregnant or trying to get pregnant, you may want to plan your destination carefully. There’s still a lot we don’t know about Zika virus — which is now widespread in several favorite tropical destinations, such as the Caribbean — and its potential pregnancy-related complications. Until we know more, it’s better to be safe and follow the precautions we’ve listed here.

Shingles, an itchy and painful rash that occurs when the chickenpox virus reactivates in your body, shouldn’t be written off as just a nuisance. If it’s not treated promptly with an antiviral drug, it can cause a host of serious long-term complications. Fortunately, there’s a vaccine that can slash your risk of shingles by half, and another, even more effective one in the pipeline.

Over the past few years, research has changed pediatricians’ recommendations for when — and how — to introduce babies to solid foods. For example, many doctors now recommend giving young children peanut products and fish very early, as this actually reduces the risk of developing allergies. Of course, every baby and family is different, so it’s always best to run your baby’s “first foods” by his doctor before giving them.

A recently published study has found that the incidence of kidney stones is on the rise. These stones, which are formed when chemicals in the urine crystallize, can cause serious complications in addition to the usual pain and urinary trouble. It’s not clear why they’re becoming more common, but climate change and rising rates of obesity may be to blame.

Many team sports have tremendous health benefits for children, but youth football, in particular, continues to pose a concern because of the high risks of concussion and other injuries. A recent NEJM article has taken a stance against allowing tackling in youth football. But is this position really the best way to promote the health and safety of youth athletes?

The U.S. Preventive Services Task Force recently updated their guidelines on screening for depression. This time around, they recommended widespread screening through primary care practices, plus gave special attention to women who are pregnant or recently gave birth. These matter-of-fact, achievable guidelines and goals have the potential to reap enormous health benefits.

Zika, a virus that was almost unknown just a short time ago, is now certain to spread to almost every country in the Americas. But why have the U.S. and other countries become more vulnerable to the threat of exotic pathogens? There currently aren’t enough data to make any solid connections, but many experts agree that the rise of global trade and travel, climate change, and ecosystem changes are all major factors.

Even though the use of lead has been regulated for many years, tragedies like the one currently ongoing in Flint, Michigan still occur. Exposure to lead in childhood can have health effects that can change a child’s life forever. We’ve listed steps you can take to keep your child — and everyone in your home — safe from lead poisoning.

Zika, a formerly rare and obscure virus, has recently spread throughout the Pacific islands and the Americas. Although Zika virus rarely makes people seriously ill, it’s been implicated in a huge rise in the number of birth defects in babies born to mothers who’ve had Zika. Although its impact in the U.S. is expected to be much less severe than in warmer climates, we’ve listed some tips to reduce your exposure to the type of mosquito that carries Zika.

Yoga is becoming increasingly popular among American children. Emerging research has shown that yoga has a number of physical and psychological benefits for children, and many classrooms now integrate yoga into a typical school day. Yoga can also be a great way for parents and children to play and interact at home. We’ve included several fun yoga-based exercises and games that parents and children can enjoy together.

A recent study of nearly 3,000 patients who had an overdose during long-term opioid treatment found that more than 90% of these patients continued to receive opioids — even after their overdose. Poor communication between emergency rooms and prescribing doctors is likely the culprit. What’s more, doctors receive little training in recognizing patients at high risk for overdose, or in treating addiction when they do spot it. An important strategy to address the current opioid crisis is to improve how doctors are educated about opioids.

There’s almost always something we can do to improve our health and well-being — even at the end of our lives. Palliative care is designed to improve the quality of life for people with life-threatening illnesses and their families by keeping a person comfortable and making sure his or her values and preferences guide the medical team’s actions. For this reason, good communication with your care team — and your loved ones — is essential, even before you or a loved one has developed a serious illness.
