Informations

The Dubbi Volcano is a stratovolcano located in the Southern Red Sea Region of Eritrea. Its peak elevation is 1625 m. There have been four known eruptions. In 1400 lava was determined to have reached the Red Sea while in 1861 ash was thrown over 250 km from the volcano. Two further events were suspected between 1861 and the 20th century. On June 13, 2011 an ash cloud that had some influence on air travel was attributed to Dubbi. However, more accurate satellite imagery later showed that Nabro was the volcano that had erupted.

Informations

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.
