An Infectious Disease of Nurserymen

During the past year, nine tree seedling nursery workers have become infected with a fungus identified as sporotrichum. This is the first time such injury has come to our attention. However, there is evidence that several people in years past may have been infected but the disease was not identified as sporotrichosis. The Public Health Service has prepared the attached summary of the disease for dis-tribution to all who handle forest tree seedlings. Note that the fungus is very widespread and is quite common among agricultural workers. Cure for the condition is not difficult after proper diagnosis. As will be pointed out, infection takes place through an abrasion in the skin. After an incubation period of 1 to 4 weeks the infection becomes evident. All too frequently, the scratch heals and is forgotten, which makes it somewhat difficult to connect the cause and effect. Preventive measures can be taken by treating all breaks in the skin, regardless of size. Washing the hands and arms with warm water and soap helps to keep them free of infection. Gloves and other protective clothing are not recommended; they may promote infection through minor abrasions unless the skin is kept dry. Lotions may help but have not been investigated thoroughly.
