Summer Resurgence

Two small, circumscribed epidemics of infantile paralysis last week marked the regular summer resurgence of that disease in the U. S.

North Carolina contained 47 new June cases, 45 cases convalescing from infection incurred during May.

In Los Angeles County Hospital a student nurse, who apparently contracted infantile paralysis from an undetected case in the hospital, spread the disease through the nurses' quarters. Last week 20 infected nurses were under quarantine, while 40 others showed suspicious prodromal symptoms.

The fact that few other cases of infantile paralysis were detected throughout the nation last week suggested that the incidence of that disease will be low this summer. However, health officers and bacteriologists are keeping close, special watch for outbreaks in New York City and Philadelphia. Those communities are significant because in Philadelphia Dr. John Albert Kolmer and in Manhattan Dr. Maurice Brodie have perfected serums against the virus which causes infantile paralysis (TIME, Nov. 26 et ante). They accomplished their work too late last year to try out their serums against any significant epidemic, are ready for eventualities this summer.
