Pertussis is caused by bacteria that attach themselves to the cilia (little hairs) that line the respiratory tract. These bacteria produce a potent toxin that inflames the respiratory tract and that prevents the cilia from functioning properly.
The disease can be serious or fatal in infants and unimmunized children. It is much milder in teens, adults, and in immunized children - but still can be a real nuisance.
People with pertussis go through four stages:
Incubation. For 5 to 21 days after exposure (usually 7 to 10 days) there are no symptoms at all while the bacteria multiply.
Prodrome. For the next 1 to 2 weeks, pertussis is not unlike a cold. People have runny noses, sneezing, and perhaps a low-grade fever. A mild cough begins that gradually worsens.
Paroxysms. The worst part of the illness lasts from 1 to 6 weeks. Spasms or attacks of coughing may come up to 15 times per day. Sometimes, especially in children, the cough is followed by a "whoop" noise as they breathe in rapidly, attempting to get air. Even so, young infants will often turn blue with the spells from lack of oxygen. The mucus is often thick and sticky. Gagging, choking, and vomiting are common. Sometimes young infants will stop breathing for varying lengths of time. This stage of pertussis is much milder in adults, teens, older children, and immunized children.
Convalescence. As if this disease were not already long enough, the cough continues for another 2 to 4 weeks, but gradually becomes less severe and less frequent. Even after the cough seems finally over, the spasms often recur briefly for the next several months - especially during colds and during exertion.
Current lab tests to detect pertussis are either slow, cumbersome, not readily available, or often fail to pick up the disease.
According to the Centers for Disease Control and Prevention people are considered to have pertussis if they have a cough lasting for at least 14 days (with no other confirmed cause) and any one of the following symptoms (even if they have been immunized): Coughing spasms or fits (coughs comes in clusters), a whooping noise while breathing in, or vomiting caused by the cough.
The case is called confirmed pertussis if there is a positive lab test or if there has been exposure to someone with a positive lab test.
During a pertussis outbreak, anyone who has a cough lasting at least 14 days (with no other known cause) probably has pertussis, even in the absence of other specific symptoms.
Pertussis is treated with an antibiotic (Biaxin, erythromycin, Septra, or Zithromax). The antibiotic doesn't much affect the length of the illness, but is very effective at stopping its spread.
People with pertussis are highly contagious for up to 5 days after starting the antibiotic.
You or your child have been exposed if you spend a total of 5 hours in the same room with someone with the disease (over a week), or if you sit next to someone with pertussis for any length of time, or if you have any contact at all with infected mucus or saliva.
Between 70 and 100 percent of susceptible people will catch pertussis if they are exposed.
Currently, most adults and teens are susceptible because the protective effect of their childhood pertussis immunizations has waned. To address this problem, it is now recommended that all teens receive a booster vaccine at 11-18 years of age (preferably between 11-12 years).
Between 60 and 80 percent of infants are protected after the first 3 doses of vaccine, but this protection begins to disappear when they are toddlers. After the 4th immunization at 18 months old, 80 percent are protected for the next 3 to 4 years. The 5th dose, at kindergarten entry, protects them for another few years. A booster dose is recommended during the teen years to bolster immunity to pertussis.
People who have been exposed to probable or confirmed pertussis should either receive a course of preventative antibiotics (and I say this as someone strongly opposed to the overuse of antibiotics), or be kept home from daycare, school, or work for at least 3 weeks. If the exposed individual develops symptoms, they should receive antibiotics to prevent further spread of pertussis to others.
Children under age 7 who have been exposed should receive a pertussis vaccine, unless they have already had 4 doses of pertussis vaccine (and the last dose within 3 years), or unless there is a compelling reason not to immunize them. Exposed teens 11-18 years old who have not already received a booster vaccine should receive one.
We lost the last generation to healthy nutrition before they were 18 months old. Parents found their children rejecting baby foods. And they didn't know what or how to feed the babies they loved. They didn't want their kids to go hungry. So the finger foods that many kids sampled were salty, partially hydrogenated, artificially colored, white-flour crackers, sugary sweets, and sippy cups of flavored high-fructose corn syrup drinks.
The babies would take these without protest! By mainlining these artificially concentrated flavors to their taste buds, we took away kids' ability to exult in the gentler rainbow of flavors in fruits, vegetables, and healthy grain products. Fruits and vegetables dropped from their diets. Many parents thought it would be easier to get them to eat veggies when they were older. Not so. The habits were ingrained for the short run and the long haul. We gave them a blueprint for failure, both for the foods they would want and for how their bodies would store and use those foods.
When your baby is in the stage of exploring by carelessly putting almost anything from bits of fuzzy lint to slow-moving spiders in his mouth, that's the moment to supply him with a variety of healthy options--not things you try to coax him to eat, but things he can discover, mouth, and enjoy. He is primed for variety more than at any other time in life. But variety on his terms.
This is a great age to turn the high chair into a treasure map. For many kids, the best way to do this is with a muffin or ice cube tray. Each slot can hold a few tasty, bite-sized treasures. You might want to cover some or all of the treasures with a napkin or a cloth. Or hide the peaches under a layer of pears. I like using one or two of the cups for a dipping sauce. Applesauce, yogurt, or pureed baby fruits and vegetables are all good choices.
Other cups might contain sweet potato cubes (easy to steam or microwave), diced pears, small half-slices of bananas, half-medallions of soft-cooked carrots, diced soft-cooked green beans, shredded apple, diced kiwi, shredded carrot, small pieces of cheese, diced avocado, quartered grapes, diced peaches, bite-sized pieces of wheat toast, or oat cereal. Imagine all of the possible combinations!
You might want to share one (or more) treasure map meal with your baby to demonstrate how dipping is done. He might like cheese in applesauce, carrots in smushed peas, or peaches in yogurt. He might just put his fingers in the applesauce and make a mess. He might try combinations you would reject. That's okay.
Some babies love it if you name the things they are eating. You will want to use portions that you are comfortable tossing, storing, or reusing in another way.
Let him set the amount he eats. As long as he and the options are healthy, don't try to get him to eat more or less. And let him select from among the options which he prefers right now. Be sure to provide at least some veggie, fruit, and grain options. If he is going only for the grains and not the veggies, increase the number and variety of veggie cups in the future, and decrease the number and variety of grain choices.
The foods you offer should dissolve easily in the mouth (like cereals) or be soft (like bananas), cooked (like carrots, peas, or spinach), or shredded (like apples) to make them easy to swallow. Apples can also be cooked. Cut them into cubes or strips and pop them in a microwave for three minutes or so. You may want to dust them with cinnamon first. When they cool, they are a delicious finger food. They don't need any added sugar. Even without it, they are sweet enough to be a yummy dessert.
