What is Valley Fever? Valley Fever (coccidioidomycosis, or cocci) is caused by the soil-dwelling fungus, Coccidioides immitis. The tiny seeds, or spores, become wind-borne and are inhaled into the lungs, where the infection starts. When soils containing the fungus are disturbed and dust is raised, spores may be inhaled with the dust.
Typhoid fever is an infectious disease caused by the bacteria Salmonella typhi. It is also known as enteric fever, or commonly just typhoid. Typhoid fever and paratyphoid fever are clinically indistinguishable diseases, collectively called enteric fever. It easily spreads through contaminated food and water supplies and close contact with others who are infected.
