Oroya fever is a disease caused by the bacteria Bartonella bacilliformis, which is transmitted by sandflies. The spelling of "Oroya" is pronounced as əˈrɔɪə, with the first syllable as schwa, followed by the long "o" and "y" sound. This fever is commonly found in parts of Peru, Ecuador, and Colombia, and can lead to severe anemia and organ failure. Without proper treatment, the mortality rate can be high, making it important to seek medical attention if symptoms arise.
Oroya Fever is a rare and severe infectious disease caused by the bacterium Bartonella bacilliformis. It is primarily transmitted through the bite of infected sand flies, which are commonly found in the high-altitude regions of South America, particularly in Peru.
The disease progresses in two distinct stages. The first stage, known as Oroya fever, occurs approximately one to two weeks after the initial infection and is characterized by high fever, severe anemia, and the development of large, tender, and deep skin lesions. The fever is often accompanied by other flu-like symptoms such as headache, body aches, and fatigue.
If left untreated or improperly managed, Oroya fever can progress into the second stage, referred to as verruga peruana. This stage is characterized by the appearance of small, reddish tumors on the skin, which can range in size from a few millimeters to several centimeters. These tumors can develop in various parts of the body, including the arms, legs, face, and mucous membranes.
Oroya fever is a potentially life-threatening condition, particularly in individuals with weakened immune systems or other underlying health conditions. Prompt diagnosis and treatment with appropriate antibiotics are crucial for a favorable outcome. Prevention measures include avoiding exposure to sand flies, using insect repellents, wearing protective clothing, and living in well-constructed houses to minimize contact with the insects.

The term "Oroya Fever" refers to a medical condition known as Bartonellosis, which is caused by the bacteria Bartonella bacilliformis. The term originated from the city of La Oroya, located in the central highlands of Peru. The disease was first identified in this region, specifically in the late 19th century during the construction of railroads in the area. The name "Oroya Fever" was given to the illness to commemorate its geographic origin.
