Single room occupancy (more commonly abbreviated to SRO):a form of housing that is typically aimed at residents with low or minimal incomes who rent small, furnished single rooms with a bed, chair, and sometimes a small desk. SRO units are rented out as permanent residence or primary residence to individuals, within a multi-tenant building where tenants share a kitchen, toilets or bathrooms. In the 2010s, some SRO units may have a small refrigerator, microwave and sink. (also called a "residential hotel"). Squatting in an unoccupied structure where a homeless person may live without payment and without the owners knowledge or permission. Often these buildings are long abandoned and not safe to occupy. Tent cities: ad hoc campsites of tents and improvised shelters consisting of tarpaulins and blankets, often near industrial and institutionally zoned real estate such as rail yards, highways and high transportation veins. A few more elaborate tent cities, such as Dignity Village, are hybrids of tent cities and shantytowns. Tent cities frequently consist only of tents and fabric improvised structures, with no semi-permanent structures at all. Outdoors: on the ground or in a sleeping bag, tent, or improvised shelter, such as a large cardboard box, under a bridge, in an urban doorway, in a park or a vacant lot. Tunnels such as abandoned subway, maintenance, or train tunnels are popular among the long-term or permanent homeless. The inhabitants of such refuges are called in some places, like New York City, "Mole People". Natural caves beneath urban centers allow for places where people can congregate.
Fungal infection, also known as mycosis, is disease caused by fungi. Different types are traditionally divided according to the part of the body affected; superficial, subcutaneous, and systemic. Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin. Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. Signs and symptoms range widely. There is usually a rash with superficial infection. Fungal infection within the skin or under the skin may present with a lump and skin changes. Pneumonia-like symptoms or meningitis may occur with a deeper or systemic infection.Fungi are everywhere, but only some cause disease. Fungal infection occurs after spores are either breathed in, come into contact with skin or enter the body through the skin such as via a cut, wound or injection. It is more likely to occur in people with a weak immune system. This includes people with illnesses such as HIV/AIDS, and people taking medicines such as steroids or cancer treatments. Fungi that cause infections in people include yeasts, molds and fungi that are able to exist as both a mold and yeast.
