Snakebites deadly as other diseases in West Africa | Science/AAAS | News - 0 views

  •  
    West Africa was under the media spotlight this year-and rightly so after nearly 11,000 people died in the largest Ebola outbreak ever recorded. But although the disease flickers in and out of the public consciousness, a new study shows that another killer was nearly as deadly: snakebites.

Ebola Drug Works Against West African Strain in Study of Monkeys - NYTimes.com - 0 views

  •  
    A study in monkeys offers the first evidence that a leading drug developed to fight Ebola works against the strain causing the current outbreak in West Africa. Six animals were infected with a very high dose of the virus and then, three days later, half were given the drug, TKM-Ebola-Makona, which was designed specifically to fight the West African strain. The monkeys that received the drug survived, but all three untreated monkeys died, researchers reported on Wednesday in the journal Nature.

Geographical Association - Ebola crisis 2014 - 0 views

  •  
    Ebola is an infectious disease, which has become a pandemic crisis causing around 5000 deaths in 2014, with a 50% mortality rate among those who have contracted the virus. The outbreak in West Africa was first reported in March 2014, and every natural case of Ebola has been in Sub-Saharan Africa with Liberia, Sierra Leone and Guinea at the epicentre of the crisis. This key stage 3-5 resource, produced by GA Consultant and Secondary Phase Committee Co-Chair Stephen Schwab, includes classroom activities and teaching ideas, and explores geographical facts, concepts and the impact the virus has had on the communities affected.

Ebola Evolved Into Deadlier Enemy During the African Epidemic - The New York Times - 0 views

  •  
    The Ebola epidemic that tore through West Africa in 2014 claimed 11,310 lives, far more than any previous outbreak. A combination of factors contributed to its savagery, among them a mobile population, crumbling public health systems, official neglect and hazardous burial practices. But new research suggests another impetus: The virus may have evolved a new weapon against its human hosts. In studies published on Thursday in the journal Cell, two teams of scientists report that a genetic mutation may have made Ebola more deadly by improving the virus's ability to enter human cells.

Where Does Ebola Come From? - Scientific American - 0 views

  •  
    The hollow Cola tree growing in a remote area of southeastern Guinea was once home to thousands of bats routinely hunted and killed by the neighborhood children. It was also a popular spot to play. A year ago, one child in particular lived within fifty meters of the tree: a two-year-old boy who died in December 2013 and later was identified as the first person in west Africa known to have developed Ebola.

BSL-4: Authorized Personnel Only - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study is based on the 2014 Ebola epidemic that spread to multiple highly populated countries in West Africa, making it the largest and most devastating outbreak in the history of the virus. The storyline, inspired by a compilation of factual information, unfolds through a fictional narrative wherein students play the role of an infectious disease specialist in training to learn about the techniques used in the detection, diagnosis, and management of Ebola virus outbreaks. The story is presented as an interrupted "clicker case" that combines problem-based case teaching methods with simulated biological laboratory inquiry through the use of Case It, a free molecular biology software, along with the NCBI's online bioinformatics tools and databases. Students work in groups to collaboratively explore various biological and social aspects of this infectious disease outbreak. This case was developed for senior students at the secondary level and can be modified for use in an introductory biology, microbiology, or epidemiology course at the undergraduate level.

What does Ebola actually do? | Science/AAAS | News - 0 views

  •  
    Behind the unprecedented Ebola outbreak in West Africa lies a species with an incredible power to overtake its host. Zaire ebolavirus and the family of filoviruses to which it belongs owe their virulence to mechanisms that first disarm the immune response and then dismantle the vascular system.

Exponential Outbreaks: The Mathematics of Epidemics - NYTimes.com - 0 views

  •  
    In this lesson, students explore the fundamental mathematical concepts underlying the spread of contagious diseases. Using a simple exponential model, students compare and contrast the effects of different transmission rates on a population and develop an understanding of the nature and characteristics of exponential growth. Students can then compare their projections with actual Ebola data from West Africa, to create context for analyzing the strengths and limitations of this simplified model.

    Charles is an African giant pouched rat, a species endemic to sub-Saharan Africa. He's also a pioneer, one of 30 of his species that live and work here in Morogoro, a few hundred kilometers west of Tanzania's largest city, Dar es Salaam, on a program to sniff out tuberculosis (TB).
