Arenal Volcano (Spanish: Volcán Arenal) is an active andesitic stratovolcano in north-western Costa Rica around 90 km (56 mi) northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano measures at least 1,633 metres (5,358 ft) high. It is conically shaped with a crater 140 metres (460 ft) in diameter. Geologically, Arenal is considered a young volcano and it is estimated to be less than 7,500 years old. It is also known as 'Pan de Azúcar', 'Canaste', 'Volcan Costa Rica', 'Volcan Río Frío' or 'Guatusos Peak'.The volcano was dormant for hundreds of years and exhibited a single crater at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it erupted unexpectedly, destroying the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them still exists today. Arenal's eruption from 1968 to 2010 is the tenth longest duration volcanic eruption on Earth since 1750. Since 2010, Arenal has been dormant.

Epidemic typhus, also known as louse-borne typhus, is a form of typhus so named because the disease often causes epidemics following wars and natural disasters where civil life is disrupted. Epidemic typhus is spread to people through contact with infected body lice, in contrast to endemic typhus which is usually transmitted by fleas.Though typhus has been responsible for millions of deaths throughout history, it is still considered a rare disease that occurs mainly in populations that suffer unhygienic extreme overcrowding. Typhus is most rare in industrialized countries. It occurs primarily in the colder, mountainous regions of central and east Africa, as well as Central and South America. The causative organism is Rickettsia prowazekii, transmitted by the human body louse (Pediculus humanus corporis). Untreated typhus cases have a fatality rate of approximately 40%.Epidemic typhus should not be confused with Murine typhus, which is more endemic to the United States, particularly Southern California and Texas. This form of typhus has similar symptoms, but is caused by Rickettsia typhi. It is carried primarily in rat feces and fleas, as well as other rodents. It is not as deadly as louse-born typhus. It occurs only during the summer and fall, when rodents are active among humans.
