Mysterious polio-like disease sweeping the US
A six-year-old boy has died after contracting a mysterious paralyzing polio-like disease that is sweeping the US.
Tests revealed he was one of hundreds of children to have recently contracted a rare virus called acute flaccid myelitis (AFM), which attacks the brain and the spinal cord. The disease was first identified in 2014 when more than 100 children were hospitalized. Scores of them are yet to make a full recovery. So far, the medical community remains largely ignorant about what causes the disease and how to treat it. The CDC has issued a report warning there has been a surge in the number of children struck down by AFM this year
Roundup of Global Volcanic Activity – Ongoing Activity for the week of 19 October-25 October 2016
Nevado del Ruiz | Colombia : Servicio Geológico Colombiano’s (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that during 18-24 October seismicity at Nevado del Ruiz was characterized by a slight decrease in the number and magnitude of earthquakes compared to the previous week. Some seismic signals were associated with gas-and-ash emissions which were confirmed by webcam images, and Parque Nacional Natural los Nevados (PNNN) and SGC officials. A steam, gas, and ash plume rose 2 km above the crater and drifted W on 18 October. Two low-energy thermal anomalies were detected on 18 and 20 October. The Washington VAAC reported that on 19 and 20 October ash plumes rose to altitudes of 7.3 and 6.1 km (24,000 and 20,000 ft) a.s.l. and drifted NW and SW, respectively. The Alert Level remained at III (Yellow; the second lowest level on a four-color scale).
Papandayan | Western Java (Indonesia) : PVMBG reported that during 1 August-17 October seismicity at Papandayan fluctuated but decreased overall. Visual monitoring occurred from the Pakuwon Village post where observers noted white plumes rising at most 35 m above the crater. The Alert Level was lowered to 1 (on a scale of 1-4) on 19 October; residents and tourists were reminded not to approach the craters within a 500-m radius.
Raung | Eastern Java (Indonesia) : PVMBG reported that, although inclement weather conditions often prevented visual observations of Raung during 1 June-19 October, white plumes were occasionally seen rising as high as 300 m above the crater. Seismicity fluctuated but continued to decrease, and then was stable. The Alert Level remained was lowered to 1 (on a scale of 1-4) on 20 October, and the public was reminded not to approach the crater.
