The incubation period of chickenpox is from ten to seventeen days. It is a mild disease, with a troublesome rash consisting of widely scattered pimples appearing over the scalp, face, and body. These pimples soon became vesicles (small blisters), which in turn quickly become pustular, afterwards drying up with heavy crust formation. Severe itching which attends these pustules may be greatly allayed by either the daily carbolic-acid-water bath or a baking-soda bath. The itching must be relieved by proper measures, for if the crust is removed from the top of the blebs by scratching, a scar usually results. The bowels should be kept open, the diet should be soft. Rigidly isolate, for chickenpox is highly contagious. SMALLPOX This disease occurs oftenest during the cold season. It spares no one unless vaccinated, attacking children and adults alike. The early symptoms are: headache, pain in the back, high fever, vomiting, and general lassitude. In many respects these resemble the symptoms of the grippe, while on the third day the eruption appears. The pimples are hard and feel like shot under the skin. Within a day or two these shotlike pimples have grown and pushed themselves beyond the skin into little conical vesicles which soon turn to pus. By the eighth or ninth day crusts are formed over the vesicle, beginning to fall off about the fifteenth day. Patients are quarantined usually eight weeks and when a case of smallpox in the home breaks out everyone in the family should be revaccinated. The strictest isolation is important from the first of the disease. We will not enter into the treatment of smallpox, for medical aid is sought at once and usually the patient is removed to a special isolation hospital. VACCINATION The history of the change brought about in the Philippines since vaccination has been introduced is an argument of itself which ought to convince the most skeptical of the value of vaccination. By all means, every child in a fair degree of health should be vaccinated. It is wise to vaccinate babies before the teething period--from the third to the sixth month. Babies with any skin trouble or suffering from malnutrition, but not living in a smallpox district, should be vaccinated during the second year. In young babies, under six months, the leg is the proper place to receive the vaccination.
