viruses

Why do microbes kill some people but not others? This is one of the hardest questions to answer in medical microbiology. Here's what we know about the senator's tragic death from the rare tickborne virus.
Identifying the cause of an infectious disease is time-consuming and not always easy. So a company called Karius has developed a blood test that analyzes cell-free DNA to identify more than a thousand pathogens.
You don't need to purchase an air purifier for your house. You have a built-in air purifier called the respiratory system.
A mumps outbreak has infected nearly 400 people in Alaska -- because apparently being stubborn and getting mumps is preferable to getting vaccinated.
Treatment advances are not easy to come by, especially in some hard-to-treat cancers like brain and triple negative breast cancer. New research, however, shows that infection with a virus could be key in making a promising treatment applicable to some cancers that were previously resistant.
Telling the difference between a viral and bacterial infection isn't always easy. Physicians end up guessing, which results in prescriptions being given for unnecessary antibiotics. A group is working on a new tool that could take the guesswork out of this important issue. 
With winter approaching, perhaps you or somebody you know will be unlucky enough to catch a nasty "stomach flu" or "24-hour flu," (which will produce some quality time in the bathroom). Now while you will almost certainly feel better within 24-72 hours, here's the catch: There's no such thing as the stomach or 24-hour flu.
Our public health strategy tends to be reactionary rather than preventative. Thus, instead of focusing most of our efforts in preparation for what is coming next, we are dumping limited resources on battles already fought. This is a dangerous gamble, considering that the Ebola virus has deadly cousins.
Although viruses are not alive, they have evolved into a perfect replication machine. And they do so without having to exert themselves at all. The infected host cell does it all because the virus tricks it. Reproduction without life; pretty fascinating.
Infectious diseases have been the focus of many news stories in the past year. Sometimes, the news is good, such as a cure for hepatitis C. Sometimes it is very bad
There are now multiple ongoing discussions about Sovaldi, Gilead s revolutionary drug for treating hepatitis C. The arguments are more or less
