Ebola: MedlinePlus Ebola hemorrhagic fever is caused by a virus. It is a severe and often fatal disease. It can affect humans and other primates. Researchers believe that the virus first spreads from an infected animal to a human. Symptoms of Ebola may appear anywhere from 2 to 21 days after exposure to the virus. FeverHeadacheJoint and muscle achesWeaknessDiarrheaVomitingStomach painLack of appetite Other symptoms including rash, red eyes, and internal and external bleeding, may also occur. The early symptoms of Ebola are similar to other, more common, diseases. There is no cure for Ebola. Centers for Disease Control and Prevention BOINC Ebola virus and Marburg virus: Complications Both Ebola and Marburg hemorrhagic fevers lead to death for a high percentage of people who are affected. As the illness progresses, it can cause: Multiple organ failure Severe bleeding Jaundice Delirium Seizures Coma Shock One reason the viruses are so deadly is that they interfere with the immune system's ability to mount a defense. For people who survive, recovery is slow. Hair loss Sensory changes Liver inflammation (hepatitis) Weakness Fatigue Headaches Eye inflammation Testicular inflammation Jun. 18, 2011 References Ebola hemorrhagic fever fact sheet.
Ebola Fast Facts Facts:Ebola hemorrhagic fever is a disease caused by one of five different Ebola viruses. Four of the strains can cause severe illness in humans and animals. The fifth, Reston virus, has caused illness in some animals, but not in humans. Ebola is extremely infectious but not extremely contagious. It is infectious, because an infinitesimally small amount can cause illness. Ebola could be considered moderately contagious, because the virus is not transmitted through the air. Humans can be infected by other humans if they come in contact with body fluids from an infected person or contaminated objects from infected persons. While the exact reservoir of Ebola viruses is still unknown, researchers believe the most likely natural hosts are fruit bats. Symptoms of Ebola typically include: weakness, fever, aches, diarrhea, vomiting and stomach pain. Typically, symptoms appear 8-10 days after exposure to the virus, but the incubation period can span two to 21 days. Italy - 1 case, 0 deaths
Earthquake prediction Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated confidence limits but with sufficient precision that a warning can be issued. Of particular importance is the prediction of hazardous earthquakes likely to cause loss of life or damage to infrastructure. Earthquake prediction is sometimes distinguished from earthquake forecasting, which can be defined as the probabilistic assessment of general earthquake hazard, including the frequency and magnitude of damaging earthquakes in a given area over years or decades. It can be further distinguished from earthquake warning systems, which upon detection of an earthquake, provide a real-time warning to regions that might be affected. Earthquake prediction and significance Prediction methods Precursors In the early 1990, the IASPEI solicited nominations for a Preliminary List of Significant Precursors.
Ebola Virus - Department of Molecular Virology and Microbiology The Agent Courtesy: CDC Dr. Lyle Conrad Ebola viruses cause a severe illness known as Ebola hemorrhagic fever that can be lethal to humans and nonhuman primates. Ebola viruses belong to a family of viruses termed Filoviridae, which are characterized by a long filamentous structure. Courtesy: CDC Frederick A. Ebola was first recognized in 1976 as the cause of outbreaks of disease in the Democratic Republic of the Congo (then known as Zaire) and in Sudan. The Reston subtype of Ebola virus was first identified in 1989 in the United States in monkeys housed in a quarantine facility in Reston, Virginia. In late 2007, a fifth strain of Ebola virus emerged in western Uganda. Where does the Ebola virus go in between outbreaks? In 2005 it was reported that fruit bats may serve as the natural reservoir of Ebola. The Problem Ebola virus is a class A bioterrorism agent, known to cause highly lethal hemorrhagic fever.

Ebola | Disease Directory Information about Ebola for Travelers No travel notices are currently in effect for Ebola. Guinea, Liberia, and Sierra Leone no longer have widespread transmission of Ebola; however, the virus can remain in certain body fluids of people who have recovered from Ebola. These body fluids include semen, fluids in the eyes, and fluids found in the brain and spine. Therefore, small numbers of cases may continue to occur. Although there is believed to be no risk of Ebola to most travelers, they should, as usual, avoid contact with sick people, dead bodies, or blood and body fluids. Travelers, particularly those who could be exposed to Ebola because of the work they are doing (see below), should enroll in the Department of State’s Smart Traveler Enrollment Program (STEP) to receive important information from the embassy about health and safety conditions and to allow the embassy to contact them in case of emergency.
The Pitch Drop Experiment | School of Mathematics and Physics Pictures above: (1) Longtime custodian of the famous experiment, the late Professor John Mainstone. (2) Three webcams trained on the experiment 24/7. (3) The Pitch Drop Experiment. (4) Close up of the pitch drop. About the Pitch Drop Experiment While the School of Mathematics and Physics at The University of Queensland has an international reputation for cutting-edge research and innovative teaching in the disciplines of Mathematics, Physics and Statistics, it is also home to the famous Pitch Drop Experiment. The first Professor of Physics at UQ, Professor Thomas Parnell, began an experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties. In 1927 Professor Parnell heated a sample of pitch and poured it into a glass funnel with a sealed stem.
