Fever Phobia

My partner went to the American Academy of Pediatrics National Conference last Fall and came home with all kinds of new information. Most of it was great. But she also told us about a new product that would be coming to market that is not so great. I personally feel that this new product will be dangerous. Not in the "it will hurt your baby directly" category, but in the "will increase parental anxiety and overtreatment" department.

What's this product?

It's called FeverFrida. It has a sticker that goes under a baby's armpit that measures a baby's temperature every 4 seconds and sends information by bluetooth to the parent so the parent can know all the temperatures. It sends an alert if the temperature is over 99F.

Can you say anxiety inducing???

Fever is our friend, people! It helps fight infection. If we get a virus or bacteria, our body elevates the temperature to kill the infectious agent. I know a lot of people worry when their kids have a fever. I wrote about that in Fever is... because it is a very common fear. But we shouldn't feed that fear. This device will feed the fear with alerts for non-fevers and a reading every 4 seconds. That's 15 readings every minute. That means 21,600 readings in 24 hours. And they encourage you to bring all those readings to your pediatrician. Please don't. I won't even humor you by looking at them. That will encourage the fear. I can't do that.

Pediatricians don't usually consider a temperature a fever until it is at least 100.4F rectally (99F under the arm), so why this gizmo alerts you right at 99F is beyond me. The American Academy of Pediatrics doesn't recommend treating a temperature under 102F unless there is significant pain. (Note: This does not apply to babies less than 2 months, underimmunized kids, and those with immune problems.) In other words, you treat the pain, not the temperature in most kids. Let the fever do it's job! So what is the benefit of having a temperature taken every 4 seconds?

The FeverFrida is from a company that I have recommended for years because they make a wonderful product called Nosefrida. The Nosefrida can get mucus out of babies and helps them get through upper respiratory infections. I do love this product despite how gross it seems to suck the snot out of baby's nose. (We do a lot of gross things as parents if they help!)

I'm disappointed that the company is trying to play on parental fears with the fever monitor. Save your money and watch your baby for symptoms and treat based on these tips.

Travelling around the world? Stay safe and healthy!

Spring Break is around the corner, which means many of my patients will be travelling to various areas of the world for vacation or mission trips. Many of these areas require vaccines prior to travel, so plan ahead and schedule a travel appointment with your doctor (if they do them) or at a travel clinic. Many insurance companies do not cover the cost of travel medicine visits, medications, or vaccines, but they are important and are a small cost in comparison to getting sick when on your trip.

Vaccinate when you can!

Immunization records will need to be reviewed, so if you are going to a travel clinic outside your medical home (doctor's office) be sure to bring the records with you. Vaccines work best when they are given in advance, so do not schedule the pre-travel visit the week you leave! Some vaccines that are recommended are easily available at your medical office but others are not commonly given so might require a trip to a local health department, large medical center, or travel clinic. Check with your insurance company to see if the cost of the vaccine will be covered or not so you can include your cost in your travel budget if needed.

Watch the food and drinks

Many diseases are spread through eating and drinking contaminated foods. If in doubt: do not eat! Cooked foods are generally safer. Any fresh fruits or vegetables should be washed in clean water before eating. Be sure all dairy products are pasteurized. Avoid street vendors, undercooked foods (especially eggs, meats, and fish), salads and salsas made from fresh ingredients, unpeeled fruits, and wild game. Drink bottled water or water that has been boiled, filtered or treated in a way that is known to be reliable. Use the same water to brush teeth. Do not use ice unless you know it is from safe water because freezing does not kill the germs that cause illness. As always, wash hands often, use sanitizer as needed when washing is not available, and avoid touching the "T" zone of your face (eyes, nose, and mouth). Do not share utensils or foods. Avoid people who are obviously ill.

Many companies that schedule international travel recommend bringing antibiotics for prevention or treatment of diarrhea. This is not recommended by many experts due to the rise of "superbugs" with the use of unnecessary antibiotics. In general, the use of antibiotic prophylaxis is recommended only for high-risk travelers, and then only for short periods. The average duration of illness when untreated will be 4 to 5 days, with the worst of the symptoms usually lasting less than a day. Antibiotics might lead to yeast infections, allergic reactions, or even a chronic carrier state (colonization) or irritable bowel syndrome. Antibiotics should be reserved for the treatment of more serious illnesses that include fever and significant associated symptoms such as severe abdominal pain, bloody stools, cramping, and vomiting. Bismuth subsalicylate is available over the counter for adults and can reduce traveler’s diarrhea rates by approximately 65% if taken four times daily. Risks of bismuth products are that it can turn the tongue and stool black and they contain salicylate. Salicylate carries a theoretical risk of Reye syndrome in children, so should be avoided in children. Probiotics and prebiotics have been shown to help prevent and treat diarrheal illnesses safely in most people with intact immune systems.

Mosquitos...

Many diseases are spread by mosquitos. Contact with mosquitoes can be reduced by using mosquito netting and screens (preferably insecticide-treated nets), using an effective insecticide spray in living and sleeping areas during evening and nighttime hours, and wearing clothes that cover most of the body. Everyone at risk for mosquito bites should apply mosquito repellant.

Non-Infectious Risks

Vehicle safety risks vary around the world. Know local travel options and risks. Only use authorized forms of public transportation. For general information, see this International Road Safety page.

Learn local laws prior to travelling.

Be sure to talk with your teens about drug and alcohol safety prior to travel. Many countries have laws that vary significantly from the United States, and some teens will be tempted to take advantage of the legal nature of a drug or alcohol.

Remind everyone to stay in groups and to not venture out alone.

Dress appropriately for the area. Some clothing common in the United States is inappropriate in other parts of the world. Americans are also at risk of getting robbed, so do not wear things that will make others presume you are a good target.

Wear sunscreen! It doesn't matter if you're on the beach or on the slopes, you need to wear sunscreen every time you're outside. Don't ruin a vacation with a sunburn.

Keep records

It is a great idea to take pictures of everyone each morning in case someone gets separated from the group. Not only will you have a current picture for authorities to see what they look like, but you will also know what they were wearing at the time they were lost.

Take pictures of your passport, vaccine record, medicines, and other important items to use if the originals are lost. Store the images so you have access to them from any computer in addition to your phone in case your phone is lost.

Have everyone, including young children, carry a form of identification that includes emergency contact information.

Create a medical history form that includes the following information for every member of your family that is travelling. Save a copy so you can easily find it on any computer in case of emergency.

• your name, address, and phone number
• emergency contact name(s) and phone number(s)
• immunization record
• your doctor's name, address, and office and emergency phone numbers
• the name, address, and phone number of your health insurance carrier, including your policy number
• a list of any known health problems or recent illnesses
• a list of current medications and supplements you are taking and pharmacy name and phone number
• a list of allergies to medications, food, insects, and animals
• a prescription for glasses or contact lenses

Specific Diseases to Prevent

Risks of illness vary depending on where you will be travelling and what time of year it will be. I refer to the CDC's travel pages and the Yellow Book for information on recommendations. Some of the most common issues to address are discussed below in alphabetical order.

Dengue Fever

Dengue is a mosquito-borne viral illness. It is seen in parts of the Caribbean, Central and South America, Western Pacific Islands, Australia, Southeast Asia, and Africa. There is no vaccine or specific treatment. Mosquito bite prevention measures are important.

Hepatitis

Infants should begin vaccinations against Hepatitis B starting at birth and against Hepatitis A starting at a year of age. Be sure these vaccines are up to date. Hepatitis A is spread through food and water, so be sure to follow the above precautions even if vaccinated.

Malaria 

Malaria transmission occurs in large areas of Africa, Latin America, parts of the Caribbean, Asia (including South Asia, Southeast Asia, and the Middle East), Eastern Europe, and the South Pacific. Depending on the level of risk (location, time of year, availability of air conditioning, etc) no specific interventions, mosquito avoidance measures only, or mosquito avoidance measures plus prescription medication for prophylaxis might be recommended.

Prevention medications might be recommended, depending on when and where you will be travelling. The medicines must begin before travel starts, continue during the duration of the travel, and continue once you return home. There is a lot of resistance to various drugs, so area resistance patterns will need to be evaluated before choosing a medication.

• Atovaquone-proguanil should begin 1–2 days before travel, daily during travel, and 7 days after leaving the areas. Atovaquone-proguanil is well tolerated, and side effects are rare but include abdominal pain, nausea, vomiting, and headache. Atovaquone-proguanil is not recommended for prophylaxis in children weighing <5 kg (11 lb).
• Mefloquine prophylaxis should begin at least 2 weeks before travel. It should be continued once a week, on the same day of the week, during travel and for 4 weeks upon return. Mefloquine has been associated with rare but serious adverse reactions (such as psychoses or seizures) at prophylactic doses but are more frequent with the higher doses used for treatment. It should be used with caution in people with psychiatric disturbances or a history of depression. 
• Primaquine should be taken 1–2 days before travel, daily during travel, and daily for 7 days after leaving the areas. The most common side effect is gastrointestinal upset if primaquine is taken on an empty stomach. This problem is minimized if primaquine is taken with food. In G6PD-deficient people, primaquine can cause hemolysis that can be fatal. Before primaquine is used, G6PD deficiency MUST be ruled out by laboratory testing.
• Doxycycline prophylaxis should begin 1–2 days before travel to malarious areas. It should be continued once a day, at the same time each day, during travel in malarious areas and daily for 4 weeks after the traveler leaves such areas. Doxycycline can cause photosensitivity so sun protection is required.  It also is associated with an increased frequency of vaginal yeast infections. Gastrointestinal side effects (nausea or vomiting) may be minimized by taking the drug with a meal and it should be swallowed with a large amount of fluid and should not be taken before bed. Doxycycline is not used in children under 8 years. Vaccination with the oral typhoid vaccine should be delayed for 24 hours after taking a dose of doxycycline.
• Chloroquine phosphate or hydroxychloroquine sulfate can be used for prevention of malaria only in destinations where chloroquine resistance is not present. Prophylaxis should begin 1–2 weeks before travel to malarious areas. It should be continued by taking the drug once a week during travel and for 4 weeks after a traveler leaves these areas. Side effects include gastrointestinal disturbance, headache, dizziness, blurred vision, insomnia, and itching, but generally these effects do not require that the drug be discontinued.  

Measles

We routinely give the first vaccine against measles (MMR or MMRV) at 12-15 months of age, but the MMR can be given to infants at least 6 months of age if they are considered high risk due to travel or outbreaks. Under 6 months of age, an infant is considered protected from his mother's antibodies. These antibodies leave the baby between 6 and 12 months. The antibodies prevent the vaccine from properly working, which is why we generally start the vaccine after the first birthday. Any vaccine dose given before the first birthday does not count toward the two doses required after the first birthday, but might help protect against exposure if the immunity from the mother is waning. It is safe for a child to get extra doses of the vaccine if needed for travel between 6 and 12 months.

Meningitis

Meningococcal disease can refer to any illness that is caused by the type of bacteria called Neisseria meningitidis. Within this family, there are several serotypes, such as A, B, C, W, X, and Y. This bacteria causes serious illness and often death, even in the United States. In the US there is a vaccine against meningitis types A, C, W, and Y recommended at 11 and 16 years of age but can be given as young as 9 months of age. MenACWY-CRM is newly approved for children 2 months and older. 

There is a vaccine for meningitis B prevention recommended for high risks groups in the US but is not specifically recommended for travel. 

Meningitis vaccines should be given at least 7-10 days prior to potential exposure.

Travellers to the meningitis belt in Africa or the Hajj pilgrimage in Saudi Arabia are considered high risk and should be vaccinated. Serogroup A predominates in the meningitis belt, although serogroups C, X, and W are also found. There is no vaccine against meningitis X, but if one gets the standard one that protects against ACWY, they will be protected against the majority of exposures. The vaccine is available for children 9 months and older in my office and a newer vaccine is approved for 2 months and up. Boosters for people travelling to these areas are recommended every 5 years. 

Tuberculosis

Tuberculosis (TB) occurs worldwide, but travelers who go to areas of sub-Saharan Africa, Asia, and parts of Central and South America are at greatest risk. Travelers should avoid exposure to TB in crowded and enclosed environments and avoid eating or drinking unpasteurized dairy products. The vaccine against TB (bacillus Calmette-Guérin (BCG) vaccine) is given at birth in most developing countries but has variable effectiveness and is not routinely recommended for use in the United States. Those who receive BCG vaccination must still follow all recommended TB infection control precautions and participate in post-travel testing for TB exposure. It is recommended to test for exposure in healthy appearing people after travel. It is possible to have a positive test but no symptoms. This is called latent disease. One can remain in this stage for decades without any symptoms. If TB remains untreated in the body, it may activate at any time. Typically this happens when the body's immune system is compromised, as with old age or another illness. Appropriately treating the TB before it causes active disease is beneficial for the long term.

Typhoid

Typhoid fever is caused by a bacteria found in contaminated food and water. It is common in most parts of the world except in industrialized regions (United States, Canada, western Europe, Australia, and Japan) so travelers to the developing world should consider taking precautions. There are two vaccines to prevent typhoid.

• Children over 2 years of age can be vaccinated with the injectable form. It must be given at least 2 weeks prior to travel and lasts 2 years. 
• The oral vaccine for children over 5 years and adults is given in 4 doses over a week's time and should be completed at least a week prior to travel. The oral vaccine lasts 5 years. 
• Neither vaccine is 100 % effective so even immunized people must be careful what they eat and drink in areas of risk.

Yellow Fever

Yellow fever is another mosquito-borne infection that is found in sub-Saharan Africa and tropical South America. There is no treatment for the illness, but there is a vaccine to help prevent infection. Some areas of the world require vaccination against yellow fever prior to admittance. Yellow fever vaccine is recommended for people over 9 months who are traveling to or living in areas with risk for YFV transmission in South America and Africa.

Zika Virus

At this time it is advised that pregnant women and women who might become pregnant avoid areas in which the zika virus is found. For up to date travel advisories due to this virus, see the CDC's Zika page.
