Can we now know every virus we’ve encountered?

Let’s face it, the human body is one amazing creation. From the unbelievable physical feats like Michael Jordan flying through the air to Bobby Fischer playing a dozen chess games at once. It often shows us there is nothing it can not do.

One of it’s amazing abilities is it’s adaptation and defense from viruses. Through out your life you will be exposed to dozens, even hundreds of viruses trying to infect your body. The body immediately defends from these viruses by antibodies specifically for each virus it encounters.

What many people don’t know is that same system that fights the war for  our health also keeps an accurate history of all it’s fallen and current enemies. Recently a new test has been developed that with a single drop of blood, can give your entire viral history.

The test, called VirScan, screens for antibodies against the 206 species of viruses known to infect humans, according to a study published in the journal Science on Thursday.

It was developed by Stephen Elledge, a professor of genetics and medicine at Brigham and Women’s Hospital and Harvard Medical School, and colleagues at the Howard Hughes Medical Institute.

Not only can the test show current infections but can also show many of the viruses encountered in the past. read full story here
