Zika Virus


Enterovirus produces symptoms much like the common  cold: fever, runny nose, sneezing, and coughing with some infected individuals  experiencing skin rash, mouth blisters, and muscle aches. Not all people who get EV D68 will have severe illness but if your child shows signs of difficulty breathing or severe wheezing with a respiratory illness, take your child to be evaluated immediately.

There is no vaccine to prevent enterovirus and no specific treatment. This is a good time to remind your children of the importance of prevention measures to minimize the spread of the virus, including the following:

  • Wash hands often with soap and water for 20 seconds.
  • Avoid touching of eyes, nose and mouth with unwashed hands.
  • Avoid kissing, hugging, and sharing cups or eating utensils with people who are sick.
  • Disinfect frequently touched surfaces, such as toys and doorknobs, especially if someone is sick.
  • Use the same precautions used to prevent the spread of influenza.

If your child becomes ill with a fresh upper respiratory illness, please consult with your child’s healthcare provider. It may also be necessary to keep your child at home to rest and recover.

Head Lice

Helpful Facts About Head Lice

  • Head lice are VERY common in children ages 3 to 12 years and are found more commonly in girls than boys.
  • Having head lice doesn’t equal poor hygiene practices.
  • Head lice have existed for many centuries and do NOT spread disease, although they are a major nuisance.
  • Live lice can only live one to two days when not on an individual’s head.
  • Live lice CRAWL, they cannot jump or fly.
  • A nit is simply a louse’s egg; the egg must hatch, which takes about 10 days, in order to produce a live louse. Nits found more than ¼ inch down the hair shaft are usually considered non-viable (they will not hatch). 
  • Direct head to head contact with an infested individual is the most common way to get head lice. Less likely is contracting head lice through sharing personal items such as combs, brushes, headphones, and hats.
  • Lice can be transmitted easily between family members, close play mates, during sleep overs, and at camps.
  • Seeking prompt and proper treatment is essential in eliminating an active case of head lice. 
  • Head lice are not as contagious as you may think…a child typically has head lice for 4 to 6 weeks before it is identified (this is the length of time it takes for a person to develop a sensitivity to the salvia of a head louse; this sensitivity is what causes the head itching and scratching). After 4 to 6 weeks of an individual being infested with head lice, one would expect that the entire classroom would have head lice and this is rarely the case. It is much easier to contract a common cold than it is to get head lice.

Helpful Tips to Prevent the Spread of Head Lice

  • Become familiar with the signs and symptoms to look for in a child with head lice (i.e. a child continuously scratching their head, sores on a child’s head caused by scratching, the presence of live lice and nits close to the child’s scalp).
  • Check your child’s head daily for live lice and nits. Live lice are usually few in number, can move quickly and are hard to detect. The most common areas to find lice are behind the ears, at the crown of the head, and at the base of the neck. Consult with the school nurse as to how to properly check your child’s head and to review exactly what a head louse and a nit look like. A louse is about the size of a sesame seed and is tan to brownish-red in color.  A nit is small, yellow or gray-white in color, and oval-shaped. Nits are not easily removed from the hair shaft, they are usually “glued” tightly which is unlike dandruff, gel, or hairspray remnants that can easily be removed.
  • Remind your child not to share personal items such as hats, combs/brushes, headphones, and scarves.
  • Encourage your child to do their best to avoid direct head to head contact with other children (this is the most common way head lice are spread from one individual to another).
  • Consider having your child with long hair wear their hair back in a pony-tail.
  • Place hats, scarves, gloves in a child’s zipped back pack or in the sleeves of a child’s jacket as this can be helpful in preventing the spread of head lice.

Head Lice Treatment Measures

  • Consult with your child’s health care provider for treatment options/recommendations as soon as head lice have been identified on your child’s head. Following product package instructions and your doctor’s recommendations are a must.
  • Notify the school nurse if your child has been treated for head lice. A child who has active head lice should be properly treated before they return to school and should see the school nurse daily for head checks.
  • Vacuum all rugs, carpets, car upholstery, and furniture daily for 10 days; starting with the day your child is identified with and treated for head lice through the second head lice treatment (typically given 7 to 10 days after the first treatment).
  • Wash all bedding, clothes, hats, and scarves on a hot cycle and dry clothes on a high heat setting for at least 30 minutes. This should be done after head lice have been identified on your child (one time should be sufficient unless you are still seeing active live lice).
  • Wash all combs, brushes, and hair accessories in hot soapy water or soak in rubbing alcohol or Lysol for one hour.
  • All non-washable items can be placed in a sealed plastic bag for 2 weeks.
  • Check your child’s head daily at home for the presence of live lice and nits. Fine comb the hair and remove all nits found. Let the school nurse know if you discover any live lice and/or nits.
  • If multiple cases of head lice have been detected in your child’s classroom, we would ask that you send in a plastic bag for your child’s belongings to be stored in during the school day.

Influenza (The Flu)  

Click HERE for information about seasonal flu.

Influenza Q & A for Parents

What is Influenza (flu)?  The flu is a contagious respiratory illness caused by viruses, which can be mild to severe, sometimes requiring hospitalization. Up to 20% of the population gets the flu.

What are the symptoms?  Symptoms of the flu may include high fever, headache, extreme tiredness, dry cough, sore throat, runny nose, muscle aches, stomach symptoms, such as nausea, vomiting, and diarrhea.

What are possible complications?  Some complications of the flu include pneumonia, dehydration, sinus or ear infections, and worsening of some conditions such as asthma and diabetes.

How does the flu spread? The flu is spread by respiratory droplets from coughing and sneezing, or touching surfaces contaminated with viruses and then touching the mouth or nose.  People are contagious beginning one day before getting symptoms and over a week after getting sick. 

How can I help prevent the spread of the flu? Everyone should practice proper hand hygiene, cover all coughs into the crux of the arm so as to decrease contamination to the hands, clean environmental surfaces regularly. 

How is a cold different from the flu?  Differences between a cold and the flu vary.  In general, the flu is worse than a cold and symptoms such as fever, body aches, extreme tiredness and dry cough are more common and intense. Colds tend to develop slowly, more likely to have a runny or stuffy nose and usually do not develop into serious symptoms.


Who should get a flu vaccine? Flu vaccine should be given to all persons, including school-aged children.

Those at greatest risk for complications of the flu include those who are:

  • under 6 months of age to 19 years of age
  • over age 50, those on long-term aspirin therapy
  • pregnant women
  • individuals with weakened immune syste
  • individuals with chronic medical conditions
  • health care workers
  • healthy household contacts, caregivers of persons with chronic medical conditions

A full list of recommendations is available at: http://www.health.state.ny.us/diseases/communicable/influenza/fact_sheet.htm

Quick Tips for Staying Healthy: Prevention is Key!

  • Get your yearly Flu vaccine
  • Cover all coughs and sneezes either with the crux of your arm or with a tissue
  • Throw tissues out immediately after use
  • Wash your hands with soap & water frequently, sing the Happy Birthday song twice while washing
  • Use hand sanitizer when no soap is available
  • Keep hands away from your face including your eyes, nose, and mouth
  • Get plenty of sleep every night, children require at least 10 hours per night
  • Increase your daily intake of fruits and vegetables
  • Stay physically active and physically fit

When to Keep a Child With Illness Home During the Flu Season

It can be difficult for a parent to decide whether to send children to school when they wake up with early symptoms of an illness or complaints that they do not feel well. Consider the following guidelines when deciding to send your child to school. 

When to send your child to school:  In general, during cold and flu season, unless your child is significantly ill, it is okay to send them to school where they have already been exposed to the same germs and where they are less likely to expose other more vulnerable people, like the very young or very old, to routine bouts of cold and flu.  It is important to remind and show your children to discard used tissues promptly, not to share personal items, to cover their mouths when they cough or sneeze, to keep their hands away from their face, and to wash hands thoroughly and often with soap and warm water. Suggest that they silently sing the Happy Birthday song twice while washing their hands.  If you send your child to school even though you suspect there is significant illness, as described above, please call the school nurse to provide her/him with phone numbers where you can be reached that day should your child become more ill and require early dismissal.

When to keep your child home: There are some situations in which it is best to keep your child home for a day to rest or to arrange for an appointment with your health care provider.  If you know your child is running a fever, it is best to allow them to remain at home in bed and take their medications until they are off all medicines and ready to learn for a full day in a classroom. If there is a pattern of your child’s asking to stay home from school, especially if they are falling behind or appear anxious by the thought of attending school, or if there does not appear to be any obvious physical symptoms, it may be a good idea to contact your school nurse and your health care provider to discuss your concerns.  Remember, whenever you keep your child home from school, please call the school nurse or attendance office before the start of the school day and leave a message that your child will be absent.

The following are a few such situations that warrant watching and possibly conferring with your health care provider: 

  1. Persistent fever higher than 100.4° orally, including a fever that requires control with medication.
  2. Child is too sleepy or ill from an illness, like vomiting and/or diarrhea, to profit from sitting in class all day.
  3. Significant cough that makes a child feel uncomfortable or disrupts the class.
  4. Sore throat that is severe, accompanied by fever and/or feeling ill, that persists longer than 48 hours, OR after known exposure to a confirmed case of Streptococcal throat infection.
  5. Honey-crusted sores around the nose or mouth or rash on other body parts that might be impetigo; OR a rash in various stages including boils, sores and bumps that may be chicken pox; OR a significant rash accompanied by other symptoms of illness such as fever.
  6. Red, runny eyes that distract the child from learning.
  7. Large amount of discolored nasal discharge, especially if accompanied by facial pain or headache.
  8. Severe ear pain or drainage from the ear.
  9. Severe headache, especially if accompanied by fever.
  10. Any condition that you think may be serious or contagious to others.

A note of caution in children 

Health care professionals strongly advise against ever using aspirin or aspirin-containing products in children without the expressed permission of the child’s medical provider due to an association to REYES SYNDROME.  Reyes Syndrome is a very serious disease that develops as one is getting over a viral illness that targets the liver and brain and is difficult to diagnose (should be suspected in anyone who vomits repeatedly about 3 to 5 days after the onset of the illness) and should be monitored by the primary medical provider.  It is best to read the labels of any over-the-counter medications/products for aspirin-containing ingredients (salicylate compounds).  Some common items (also applies to generic brands): Alka Seltzer, Exedrine, Maalox, Pamprin, topical skin products (acne treatments), muscle and joint creams, wart removers, and others.

International Travel & Vaccine Preventable Diseases

For families planning to travel internationally over the summer months, now is an excellent time to review your families’ immunization status with your private health care provider to make sure you and your family are sufficiently protected against diseases such as polio, measles, mumps and pertussis. Preventable diseases once thought to be eliminated are resurfacing, some even reaching epidemic proportions. The Center for Disease Control (CDC) and the World Health Organization (WHO) have issued traveler guidelines that you may want to review and discuss with your private health care provider particularly if you are planning to travel to any of the following locations: Pakistan, Cameroon, Syria, Afghanistan, Equatorial Guinea, Ethiopia, Iraq, Israel, Somalia, or Nigeria. 

Travelers to polio-affected areas should review with their health care provider the following guidance prior to travel:


Travelers also may be impacted by new WHO Polio Vaccination Recommendations in countries with ongoing poliovirus transmission.  Your primary care provider should be able to address these recommendations with you.  In addition, it has been recommended that travelers to or from all 10 countries should be given a WHO/IHR International Certificate of Vaccination or Prophylaxis:

What is Measles?  Measles is a highly contagious and very serious respiratory disease caused by a virus. 

What are the symptoms? Measles symptoms usually appear in 10 to 12 days after exposure, but can occur as late as 18 days after exposure. Symptoms generally appear in two stages. In the first stage, which lasts two to four days, the individual may have a runny nose, cough and a slight fever. Eyes may become reddened and sensitive to light while the fever gradually rises eachday, often peaking as high as 103° to 105° F. Small bluish white spots surrounded by a reddish area may also appear on the gums and inside of the cheeks. The second stage begins on the third to seventh day and consists of a red blotchy rash lasting five to six days. The rash usually begins on the face and then spreads downward and outward, reaching the hands and feet. The rash fades in the same order that it appeared, from head to extremities.

How is Measles spread? Measles is spread through contact with nasal or throat secretions of infected people. When an infected person sneezes, coughs, or talks, droplets become airborne and are infectious. Droplets from an infected person landing on surfaces may remain active and contagious for up to 2 hours.

Who is at risk? Although measles is usually considered a childhood disease, it can be contracted at any age by individuals who never had the measles disease or been vaccinated. A person is considered immune from contracting measles if they have received two doses of Measles, Mumps, and Rubella (MMR) vaccine OR if they were born before January 1, 1957, OR have a history of laboratory-confirmed measles, OR have a blood test confirming immunity. Unimmunized individuals, including adults, should contact their private health care providers to check on their immunization status. Anyone who believes they might have been exposed, especially pregnant women, should contact their private health care providers.

The single best way to prevent measles is to be vaccinated. More information regarding measles can be found at: http://www.health.ny.gov/diseases/communicable/measles/fact_sheet.htm

Tick Bite Prevention & Tick Removal    

Where can ticks be found? You may come in contact  with ticks during any activities outdoors, particularly near wooded or grassy  areas. Blacklegged ticks most often live in moist, humid  environments. 

What do ticks look like?

How can I avoid ticks? You can avoid ticks by  avoiding tall vegetation, such as tall grass or shrubs. When hiking, walk  in the center of paths or trails. 

How can I repel ticks? You can repel ticks for  several hours by applying a repellent containing 20% or more of DEET on skin or  clothing. Products containing 0.5% permethrin can be used to treat  clothing, boots, jackets and camping or hiking gear. Product directions  for application must always be followed. Avoid applying these products to  your hands and face, and consult with your child’s pediatrician before  use. 

For tick repellent  information for your pets, check with your veterinarian.

Where on the body do I look when performing daily tick inspections? After being outside,  perform a full body skin check. Bathing or showering after being outside  allows for easier detection of ticks. Special attention should be paid to  several areas of the body including, but not limited to:   

  • under the arms
  • in and around ears
  • inside and around the belly button
  • behind the knees
  • on your head, by inspecting in and around       your hair
  • between the legs
  • around the waist

All clothing, camping  equipment, and pets should be checked for ticks. Ticks can enter the home  through pets or clothing and later attach to a person’s skin. Placing  clothing and blankets in the dryer on high heat will effectively kill any ticks  potentially living on these items.    

How do I safely and properly remove a tick? If you should find a  tick, stay calm and do not panic. A pair of fine-tipped tweezers can be  used to safely and effectively remove a tick from the skin. Avoid using  your bare hands to remove a tick. It is extremely important to remove a  tick as soon as possible because the chance of contacting Lyme disease is  lessened if the tick has been attached to the skin for less than 24  hours. 

Steps to remove a tick:   

1). Locate fine-tipped  tweezers and grasp the tick with the tweezers as close to the skin surface as  possible. Pull upward as steady as possible using even pressure. You  want to remove all parts of the tick, including all mouth parts. 

2). Place the tick in a  sealed baggie or sealed container to bring to your doctor. Ticks can be  sent for laboratory testing to determine the tick type and potential for  disease.

3). After removing the  tick, the area of the skin needs to be thoroughly washed with soap and  water. Your hands should also be thoroughly washed with soap and water.

4). Always follow-up  with your doctor if you should find a tick and after removal of a tick. If  you experience a rash or a fever within several weeks of removing a tick, visit  your doctor immediately.

Zika Virus

January 27, 2016 - With the upcoming vacation periods which may involve travel to  the areas identified below, we felt it important to share the health advisory  from the New York State Department of Health regarding Zika virus. 

What is Zika Virus? Zika virus is mosquito borne and can be associated with  travel to the Caribbean, Mexico, Central, and  South America. All travelers are urged to practice enhanced precautions while  traveling. 

What are the symptoms  associated with Zika Virus? Zika virus can cause fever, rash, conjunctivitis (red/pink  eyes) and joint pain. Symptoms are generally mild and may last several days to  a week.

Who is at risk? Anyone who is living in or traveling to an area where Zika  virus is found who has not already been infected with Zika virus is at risk for  infection.  However, the greatest cause  for concern appears to be exposure by pregnant women due to the risk to the  developing fetus. Therefore, mosquito protection would be important to those  traveling to affected areas. Individuals who are pregnant or planning to become  pregnant and have travel plans to these areas may want to view the Center for Disease Control link below and discuss the matter with their private physician.

What is the  treatment? No specific antiviral treatment is available for Zika virus disease.  Treatment is generally supportive and can  include rest and fluids.

What is the  prevention? No vaccine or prevention drug is available.  The best way to prevent Zika virus infection  is to:

  • Avoid mosquito bites.
  • Use air conditioning or window and door screens when indoors.
  • Wear long sleeves and pants, and in consultation with your doctor, use insect repellents when outdoors.
  • Until more is known and out of abundance of caution, pregnant woman should consider postponing travel to the Caribbean, Mexico, Central, and South America.

For more information, Zika Virus  Travel Health Notices and FAQ can be viewed from the link below:   http://www.cdc.gov/zika/pregnancy/travel-health-notices.html  http://www.cdc.gov/zika/disease-qa.html
