“Measles is a serious disease. When parents fully realize that it is the most contagious of all the diseases, that it frequently leads to permanent deafness or to defective eyesight that it causes more deaths than does scarlet fever they will be more willing to protect their children from it and more anxious to obtains a doctor’s services promptly”
“Measles is essentially a disease of early childhood, It is most serious at this period. Among the children of Pennsylvania contracting measles, 32% are under five years of age and 85% of the many deaths from this malady occur in this age period.”
” Children of the household who are known to have had measles may attend school if they obtain permits from the health officer to do so. Teachers must not accept any other certificate. The health officer, however, will not issue this permit unless the records show that the child at one time had been ill and quarantined for the disease. Children who have not had measles much remain out of school and at home under quarantine until released by the health officer. Adults are not included in the quarantine.”
