A week is a long time in science. With Ebola, the U.S. government admits new patient; joint pains stall a major clinical trial; U.S. grants immunity to vaccine developers; and new doubts are raised about Ebola dying quickly outside the human body.
Big Pine Key -
A virus that has killed over 1,560 Atlantic bottlenose dolphins since July, 2013 has now reached the Florida keys. The remains of a dolphin that died after being stranded on Bahia Honda State Park has tested positive for morbillivirus.
The Ebola virus is adept at moving from from person to person via direct contact with infected body fluids. However, how long can the virus survive outside of the body? New research seeks an answer.
HIV seems to be evolving. The virus's ability to cause AIDS is slowing down. A new study shows that those infected by HIV are progressing to AIDS more slowly. This means that the virus becomes less virulent.
While Ebola continues to cause havoc and death in West Africa, another virus family could be emerging a significant threat. These viruses (henipaviruses) may have jumped from fruit bats into humans in Africa.
British scientists announced trials on a 15-minute Ebola test in Guinea as French President Francois Hollande arrived in Conakry on Friday, becoming the first Western leader to visit one of the countries devastated by the epidemic.
Madagascar said Monday it was trying to contain an outbreak of plague -- similar to the Black Death that swept medieval Europe -- that has killed 47 people and is spreading to the capital Antananarivo.
Certain types of avian influenza viruses have the potential to cause more severe disease in humans compared with others. This has come from new research which warns such viruses must be monitored carefully.
The media has widely reported that any suspected of having Ebola, of who has been in close contact with an Ebola patient, should be monitored for 21 days to see if Ebola symptoms appear. Some scientists are questioning if 21 days is really long enough.
Although the human immunodeficiency virus (HIV) inserts itself at different locations in a human cell, researchers have found that specific integration sites determine the speed that the infection spreads at.
Although cervical cancer screening saves lives, about eight million women ages 21 to 65 years have not been screened for cervical cancer in the past five years. This is according to a study from Centers for Disease Control and Prevention (CDC).
Biologists have discovered that mosquitoes bite male birds twice as often as they bite females. The same is true with people: mosquitoes bite men more often than women. Knowing this could help to stop the insects from spreading viruses to people.
Polio has almost been eliminated from the world and just two countries remain endemic: Afghanistan and Nigeria, with cases also high in parts of Pakistan. A new report considers how the final steps can be taken to eliminate the disease.
An experimental drug is being trialed for Ebola may have a new application: norovirus (the “winter vomiting virus”). Scientists are currently undertaking studies on mice to test the drug’s effectiveness.
The destruction of vials of smallpox - one of the world's deadliest diseases - found hidden on U.S. soil has been delayed. The reason? Because the World Health Organization (WHO) has been too busy with Ebola.
In an ironic twist, Louisiana state health officials are prohibiting scientists who has visited Liberia, Sierra Leone, or Guinea in the past 21 days from attending a meeting on tropical diseases in New Orleans.
Researchers have developed a new test for porcine epidemic diarrhea virus. This virus has been spreading throughout the pig population within the U.S. The test differentiates the genetic material of the virus from that of other viruses.

Ebola particles are quite scary up close, but you should not buy into the fear right away.
This electron micrograph depicts the vesiculovirus responsible for vesicular stomatitis (VS) in horses, cattle and pigs. As a member of the Rhabdoviridae family of viruses, you’ll note the morphologic similarity, i.e., bullet-shaped virion, between this vesicular stomatitis virus (VSV), and the rabies virus.
