Lassa Fever Discovered in US Man

A Minnesota man who recently returned home after visiting West Africa has tested positive for Lassa fever, health officials have confirmed. The man went to a hospital in Minnesota on March 31, complaining of fever and confusion. Blood samples sent to Centers for Disease Control and Prevention tested positive for Lassa fever on April 3. The man is recovering and is in stable condition, according to the Minnesota Department of Health. Lassa fever is a severe viral disease that causes fever and bleeding, and is common in West Africa but rarely seen in the United States. Only seven other cases of Lassa fever cases have been identified in the U.S., with the last one reported in Pennsylvania in 2010, according to the CDC. All cases were likely imported from other countries.

Volcanos

Roundup of Global Volcanic Activity:

Tungurahua (Ecuador): The volcano entered a new vigorous eruptive phase yesterday evening. A moderately strong vulcanian explosion occurred at 18:10 (local time) and produced an eruption column rising several kilometers as well as small pyroclastic flows on the cone. The eruption plume (originally estimated to have reached up to 50,000 ft / 15 km altitude, but probably much lower than that) drifted to westerly directions. Ash / lapilli fall with 1-3 cm diameter clasts occurred in the areas of Bilbao, Choglontus, Chacauco and Cusúa. The explosion, which likely cleared the conduit from a solid plug was followed by frequent, smaller explosions accompanied by a constant tremor signal of high energy. When the volcano was not hidden in clouds, the expulsion of incandescent blocks that rolled down the upper flanks, and steam-gas-ash emissions could be observed. Individual stronger explosions also occurred intermittently, some of which rattled the windows and doors of the Tungurahua Volcano Observatory (OVT), located 14 Km northwest.
