The Credo Current – July 31

Today’s post provides you with background information on items that are in the news this week.

Researchers presenting at the International AIDS conference last Thursday, 26 July are cautiously optimistic about the potential for a combination of antiretroviral drugs and bone marrow transplants to cure HIV. So far one patient in Berlin has remained HIV-free with no further trace of a virus in his system, and two Boston patients have remained HIV-free for 17 months after bone marrow transplants, although doctors say there may be traces of HIV in tissues outside the bloodstream.


Geographic Information SystemsGeographic Information Systems
Geographic Information Systems, or GIS, are systems that store, manipulate, analyze and display information in relation to geography. GIS uses elements of cartology, topography and statistics, and helps users to visualize information geographically. One popular example of GIS is Google Maps, which can display information like weather, traffic and things to do in the area. Google Maps is in the news this week because it just received an update to its aerial and satellite imagery for 25 cities and 72 countries, including Olympic Park, London, allowing users to see a high-resolution street view of the stadium.


Ebola virus diseaseEbola Virus Disease
Ugana is currently fighting an ebola outbreak that has killed at least 14 people in the last few weeks and infected even more. Ebola is a hemorrhagic fever virus named after the Ebola River in Congo, where the first outbreak was recorded in 1976. Initial symptoms include fever, headaches, muscle aches and loss of appetite, followed in a few days by blood clots, hemorrhaging, nausea, vomiting and diarrhea. Ebola’s fatality rate can range from 50% to 90%, depending on the strand of the virus, and death occurs 8-17 days after infection.
