What is rhinovirus?

Rhino-what?? Have you been wondering what all the sneezing is about? Even though the weather is beginning to warm up in Dakar, it is still the season for rhinoviruses. Rhinoviruses are the most common cause of the most common reason for children’s doctor visits and missed school days.


The “common” cold. But don’t worry, your child’s cold will most likely go away on it’s own in about a week or so. Read on to find out more about rhinoviruses, and remember if your child’s cold does cause him or her to have a fever (oral temperature of 100 F or 37.8 C), keep your child home from school to rest and recover.


What Is a Cold? The common cold is a contagious viral infection of the upper respiratory tract. Most adults catch a cold from time to time, but kids can get eight to ten colds per year or more.


What Causes a Cold? Rhinoviruses are carried in invisible droplets in the air or on things we touch. These viruses can get into the protective lining of the nose and throat, setting off an immune system reaction that can cause a sore throat, headache, and trouble breathing through the nose. Dry air — indoors or outside — can lower resistance to infection by the viruses that cause colds. Smokers are more likely to catch a cold than people who don't smoke, and their symptoms probably will be worse and last longer, and can even lead to bronchitis or pneumonia.


What Are the Signs and Symptoms of a Cold? The first symptoms of a cold are often a tickle in the throat, a runny or stuffy nose, and sneezing. Kids with colds also might feel very tired and have a sore throat, cough, headache, mild fever, muscle aches, and loss of appetite. Mucus from the nose may become thick yellow or green.


Are Colds Contagious? Colds are very contagious, especially in the first 2 to 4 days after symptoms begin. They can even spread for a couple of weeks after someone starts feeling sick. Colds spread through person-to-person contact or by breathing in virus particles, which can travel up to 12 feet through the air when someone with a cold coughs or sneezes. Touching the mouth or nose after touching a contaminated surface can also spread a cold.


How Long Do Colds Last? Cold symptoms usually appear 2 or 3 days after exposure to a source of infection. Most colds clear up within 1 week, but some last a bit longer.


How Are Colds Diagnosed? Your doctor won't be able to identify the specific virus causing cold symptoms, but can examine your child's throat and ears and take a throat culture to make sure the symptoms aren't from another condition that may need treatment. If symptoms get worse instead of better after 3 days or so, the problem could be strep throat, sinusitis, pneumonia, or bronchitis, especially if your son or daughter smokes. If symptoms last for more than a week, appear at the same time every year, or happen when your child is around pollen, dust, or animals, an allergy could be to blame. Kids who have trouble breathing or wheeze when they catch a cold could have asthma.


How Are Colds Treated? Colds will clear up on their own without specific medical treatment. Medicine can't cure a cold, but can ease symptoms like muscle aches, headache, and fever. You can give your child acetaminophen (paracetamol) or ibuprofen, based on the package recommendations for age or weight. But never give aspirin to children or teens, and may experts now believe that there's usually no reason to give over-the-counter (OTC) decongestants and antihistamines to any child younger than 6.


Can Colds Be Prevented? Because so many viruses cause colds, there isn't a vaccine to protect against them. To help avoid catching one, kids should:

· stay away form someone who has a cold

· avoid being around someone who smokes

· wash their hands well and often, especially after blowing their noses

· sneeze or cough into a tissue or their elbow, not into their hands

· not share towels, drinking glasses, or eating utensils with someone who has a cold

· not pick up other people's used tissues


How Can I Help My Child? To help ease cold discomfort, you can:

· put saline (saltwater) drops in the nostrils to relieve nasal congestion

· run a cool-mist humidifier to increase air moisture

· dab petroleum jelly on the skin under the nose to soothe rawness

· give hard candy or cough drops to relieve sore throat (only for kids older than 6)

· run a warm bath or use a heating pad to soothe aches and pains

· run a hot shower to create a steam-filled bathroom where your child can sit to help clear stuffiness


What about chicken soup? Chicken soup contains a mucus-thinning amino acid called cysteine, and some research shows that chicken soup helps control congestion-causing white cells, called neutrophils. In the end, just make sure your child eats when hungry and drinks plenty of fluids like water or juice to help replace the fluids lost during a fever or from mucus production.


When to Call the Doctor. Always call the doctor if you think your child might have more than a cold, your child gets worse instead of better, or if your child has any of these symptoms:


· coughing up a lot of mucus

· shortness of breath

· unusual lethargy/tiredness

· inability to keep food or liquids down or poor fluid intake

· increasing headache or facial or throat pain

· severely painful sore throat that interferes with swallowing

· fever of 103°F (39.3°C) or higher, or a fever of 101°F (38.0°C) or higher that lasts for more than a day

· chest or stomach pain

· swollen glands (lymph nodes) in the neck

· earache


Like most viral infections, colds just have to run their course. Getting plenty of rest and drinking lots of fluids — juice and water — can help your child feel better while on the mend. And keeping up regular activities like going to school probably won't make a cold any worse. But it will increase the likelihood that the cold will spread to classmates or friends. So hard as it may be, you might want to put some daily routines aside until your child is feeling better.


Cheers to your Health,
