Fungal Infections

Fungal infection can be defined as an infectious disease caused by fungi. A fungal infection is also referred to as mycosis. Fungal infections are contagious, spreading from person to person. Mycosis can be contracted even from an infected animal or contaminated soil. The most common symptom is skin rashes and vaginal discharge in females.

Question

Mention microbial infections and most people think of hospitals, not summer camp. But being outdoors in the sunshine
and fresh air is not without risk. In June 2012, a camp counselor in Omaha, Nebraska, was diagnosed with histoplasmosis,
a fungal infection with symptoms similar to pneumonia: fever, headache, and respiratory distress. Although most people
suffering from histoplasmosis will recover without medical treatment, the very young, very old, and people with chronic
lung conditions are at greater risk for developing severe disease, which may on rare occasions prove fatal. In areas of the
eastern and central United States, where Histoplasma capsulatum is endemic, dirt contaminated with bird and bat guano
often contains spores of the fungus. Disturbing such contaminated dirt is a known risk factor for developing the disease.
Because the sick camp counselor was one of 32 that worked at the camp, and the camp served 797 children, the Douglas
County Department of Health (DCDH) and the Nebraska Department of Health and Human Services (NDHHS) began an
investigation to determine the extent and source of the outbreak, so as to prevent further infections. Initial testing
revealed 17 counselors (53%) whose blood serum or urine contained antigens from Histoplasma capsulatum, these were
deemed confirmed cases of the disease. Of 153 responses to a questionnaire sent to camp attendees, 17 campers (11%)
had confirmed or suspected histoplasmosis (suspected cases were those in which illness was present but laboratory
results were inconclusive or unavailable).
Prior to the beginning of camp, the counselors participated in a camp cleanup, where the 12 campsites were prepared for
the summer. Preparations included raking leaves, cleaning picnic tables, digging fire pits, and moving firewood.
Counselors reported that they found bird and bat guano on picnic tables and the dirt floor of camp shelters at two of the
campsites. Campers arrived a week later and took part in nature walks, outdoor games, wilderness training, and arts and
crafts, but did not engage in high-risk activities like those performed by the counselors earlier in the summer. Analysis of
data collected by the DCDH and NDHHS determined that campers assigned to campsites where guano was seen were
more than twice as likely to become ill than those campers assigned to campsites greater than 20 yards away. In fact, the
data showed that the farther away a camper was from a site where guano was found, the less likely they were to become
ill. Based on this report, the camp was relocated to a different park, and the city's parks and recreation division was given
recommendations to prevent bat roosting, recognize potentially contaminated areas, and properly deal with such sites.

Diseases caused by different types of pathogens have their own seasonality. That is, there is a higher frequency of bacterial and viral diseases in winter and a higher frequency of fungal and parasitological problems in summer. I explain winter, you explain summer. In winter, people are indoors with frequent touching of the same surfaces, breathing of the same air, as well as frequent contact. Bacterial diseases spread through touching of common surfaces while viral diseases also are spread through breathing in of infectious aerosols (someone’s sneeze, microbes in recycled air). Therefore the incidence of bacterial and viral diseases are greater during the winter. Why are fungal and protozoan diseases more important in the summer? (3 good reasons).
