Lyme Disease and Ticks: Symptoms, Treatment and Prevention

Ticks might look like insects, but they’re not. They’re part of the arachnid family, which includes spiders. When a tick bites, it attaches itself to the skin and sucks blood. Most tick bites are harmless and don’t need medical treatment. But some ticks (like the deer tick) can carry harmful germs that cause illnesses like Lyme disease. How can I prevent tick bites and Lyme disease? While enjoying the outdoors, it’s important to remember that there are hundreds of kinds of ticks, and not all ticks carry Lyme disease. Here are some tips to help protect your family from the risk of a tick bite before heading out, and what to do after a day of exploring nature: Ticks removed within 36 hours are less likely to spread diseases. So, if you pluck the tick off right away, your child can’t be infected. Because ticks (especially deer ticks) are tiny, they may be hard to […]

5 Tips for a Healthy Flu Season

It’s that time of year again: flu season. Thankfully, there are some steps you can take to help you and your kids avoid spending the winter feeling terrible and curled up with a box of tissues. Just ask your child to follow these five tips from our medical experts: Wash Your Hands Washing your hands is the single most effective method of preventing respiratory illnesses, including the flu. Keep in mind, when washing your hands, make sure to scrub for at least 20 seconds. (Just tell your kids that’s about the time it takes to sing Happy Birthday twice.) Always make sure to wash your hands before and after eating food, after contact with frequently touched surfaces, and after blowing your nose, coughing or sneezing. If you don’t have access to soap and water, make sure to use hand sanitizer. Cover Your Coughs (and Sneezes) When you cough or sneeze, […]

All About Walking Pneumonia (Mycoplasma Pneumonia) in Kids

Between colds, the flu, and other viruses, lots of kids get sick in the fall. This year it could be due to a lung infection called walking pneumonia that’s becoming more common, especially in young children. It’s also known as mycoplasma pneumonia since it’s often caused by the bacteria mycoplasma pneumoniae. While usually mild, it can still make kids uncomfortable and cause breathing problems. Here’s what you need to know about this rising health issue. What is walking pneumonia? Walking pneumonia is a kind of bacterial infection that affects the lungs. It tends to cause milder symptoms than other forms of pneumonia, so children who have it feel well enough to walk around instead of staying in bed. This is why it’s called “walking pneumonia.” How common is walking pneumonia in kids? Each year, about 2 million people get walking pneumonia. Since spring, the infection has been more common than […]

Little One’s Got the Sniffles? Watch for Breathing Trouble

You’ve probably heard about respiratory syncytial virus or RSV a lot lately. That’s because cases of this illness have increased since last year. RSV mainly causes cold symptoms, and most people who get it get better on their own. But when babies or toddlers get RSV, it can turn into something more serious called bronchiolitis. Bronchiolitis causes the lung’s tiny airways (bronchioles) to swell and fill with mucus. This makes it hard to breathe. Bronchiolitis usually gets better on its own, but sometimes kids need treatment in the hospital. With the winter season upon us, it’s good to know what to look for — and when to get help — the next time your child comes down with a nasty cold. Why are RSV cases on the rise?  Doctors aren’t exactly sure why, but it may be because fewer people are wearing masks now. RSV is a common childhood illness, […]

Your Child’s Flu Vaccine: Now Is the Time

Your family’s fall calendar may be packed with sports activities, pumpkin picking, and school events, but don’t forget to make time for one very important appointment: your child’s flu vaccine. Experts say now is the best time to get the flu vaccine. Getting it at the start of flu season — which runs from October to May — gives the body a chance to make antibodies that protect from the flu. For the last couple of years, flu rates have been lower than usual, in part due to the precautions taken to prevent COVID-19. But now kids are returning to school with fewer precautions and resuming pre-pandemic activities. The flu will start to spread again, which is why families should get their flu shots as soon as possible. Why Is the Flu Vaccine Recommended? While the flu vaccine isn’t 100% effective, it still greatly lowers a person’s chances of catching […]

Should Parents Worry About Parechovirus?

It may feel like viruses are in the news a lot these days. And perhaps you just heard about parechovirus (puh-REH-ko-veye-rus). Well, it turns out that parechovirus isn’t new! What Is Parechovirus? Parechovirus is a virus that’s been around for many years. Parechovirus infection is pretty common, especially in kids. Did you know that most kids get a parechovirus infection by the time they turn five years old? You probably weren’t even aware if your child has had a parechovirus infection. That’s because kids usually have no symptoms or just mild ones.  Parechovirus can spread when someone comes in contact with infected poop or infected droplets of saliva or mucus that come out in a cough or sneeze. It can also spread when someone touches a contaminated surface or object. Symptoms of parechovirus infection are like symptoms that come with other cold viruses, such as a sore throat, runny nose, […]

Wait No More: Nearly All Kids Can Now Get the COVID-19 Vaccine

Many parents are breathing a sigh of relief that they can finally get their babies, toddlers, and preschoolers vaccinated against COVID-19. Two brands of the vaccine have now been authorized for children as young as 6 months old, so the little ones can now join the ranks of people ages 5 and up who have helped protect themselves. So does your young child really need a COVID-19 vaccine? After all, younger children often have milder illness when they get infected. The answer is a resounding “yes,” since many young children have had serious symptoms requiring hospitalization, and some have even died. Small children can even develop long COVID, with symptoms that bother them for a long time. Parents might also wonder why it took so long for the vaccines to be authorized for this age group. It took a long time to get the vaccines authorized for young children because […]

To Mask or Not to Mask? Good Question.

To Mask or Not to Mask? Good Question.

Across the country, states are beginning to lift universal mask mandates, including in schools. However, COVID-19 still poses a risk for many families, especially for children too young to be vaccinated. What is a parent to do? Dr. Salwa Sulieman, an infectious disease specialist at Nemours Children’s Hospital, Delaware and a mom of three suggests looking to the numbers to help you make a decision about whether to continue wearing a mask, despite the lifted mandates. Look at the Numbers “I base masking recommendations on what the numbers in the community are doing. I tend to think about incidence of COVID-19 infection per 100,000 persons, which you can find on most state health department websites,” says Dr. Sulieman. Dr. Sulieman recommends considering optional masking when your state begins reporting an incidence rate of 50-100 cases per 100,000 persons. When your state gets to less than 10 per 100,000, there’s very […]
