How to Control Contagious Infections in Children

The flu, pink eye, stomach bugs: When you know your child is sick, you keep him home. The problem is, kids can come in contact with germs and spread an infection before symptoms appear.

Here's what you can do to lower the chances of that happening.

Practice the Basics

To keep contagious diseases at bay, the first step is prevention.

  • Make sure you and your children eat right and are well-rested. That boosts the body's defenses.
  • Don't share items like cups, spoons, forks, straws, towels, pillows, or toothbrushes.

Tips for Hand Washing

Wash them:

  • Before and after preparing food
  • Before eating
  • After using the bathroom
  • After handling animals or their waste
  • After coughing or sneezing
  • More frequently if someone at home is sick

A quick rinse just isn’t enough. To wash well:

  1. Wet your hands and lather up with liquid or bar soap.
  2. Scrub all surfaces for 15 to 20 seconds.
  3. Rinse well, and dry your hands.
  4. No soap and water? Use alcohol-based disposable hand wipes or gel sanitizers.

What to Disinfect and How

Disinfect:

  • Phones
  • Stair railings
  • Countertops
  • Bathroom surfaces (toilet seats, handles, faucets)
  • Remote controls
  • Microwaves and refrigerator handles
  • Door handles
  • Light switches
  • Toys

To stop germs in their tracks, the CDC recommends virus-killing chlorine bleach. Add 1/4 cup bleach to 1 gallon of warm water. Let the mixture to sit on surfaces for 10 minutes before rinsing.

When you disinfect, wear rubber gloves and a mask if the chemicals bother you, and open doors and windows.

Spot the Warning Signs of an Illness

The sooner you do that, the more likely you are to keep it from spreading.

Colds and coughs usually spread when a sick person coughs, sneezes, or talks. They might also have a runny nose and mild fever.

The fluoften spreads when a sick person coughs or sneezes. Symptoms can include a runny nose, cough, fever, chills, and body aches. The disease is contagious about 1 day before symptoms appear and 5 days after. The illness can lead to serious complications that land some people in the hospital. The best way to avoid catching it is to get your annual flu vaccine.

MRSA (methicillin-resistant Staphylococcus aureus) can be spread by touching another person who has it. The best way to prevent it is to keep your hands clean, avoid touching other people’s wounds and bandages, and keep your own cuts and scrapes covered with bandages until they're healed. Also, don’t share sports equipment or clothing.

Pinkeye is highly contagious. It's spread when you touch your eye after coming into contact with something an infected person has touched. Symptoms include eye redness, itching, pain, and discharge. Never touch your eye without washing your hands, and don't share towels or eye makeup.

Stomach flu (viral gastroenteritis) is spread by not washing your hands after using the bathroom and before handling food. Symptoms include cramps, diarrhea, and vomiting. They usually show up 1 or 2 days after exposure to the virus, which is carried in the stool of a sick person.

Strep throat is common in children and spreads when a sick person breathes, coughs, or sneezes. Tiny droplets with the strep bacteria can be breathed in by other people. Symptoms include sore throat, fever, headache, white patches in the throat, stomach ache, and sometimes a sandpaper-like rash. Strep can last 2 to 5 days. You’re contagious for 24 hours after starting an antibiotic.

Whooping cough (pertussis) and chickenpox are childhood diseases that can be prevented by vaccines, so they aren’t as common today. Still, they can happen in unvaccinated children. Whooping cough causes a high-pitched "whoop" in between coughing spells that can last up to 12 weeks. Children with whooping cough can be contagious for about 3 weeks. Chickenpox causes blisters all over the body. It's most contagious for 1 to 2 days before symptoms appear and until the blisters have crusted over.
