Freedom is the most contagious virus known to man.
Dance music is like a virus: it has affected so many different genres.
Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.
The discovery that I soon made that the guinea pig was also susceptible to infection made it possible for me, from the third year on, to preserve the virus on this animal.
If a healthy person were placed on the other side of a room from a person who was sick with AIDS, the AIDS virus would not be able to drift across the room through the air and infect the healthy person.
The virus that causes AIDS is the trickiest pathogen scientists have ever confronted. It mutates furiously, it has decoys to evade the immune system, it attacks the very cells that are trying to fight it, and it quickly hides itself in your genome.
Let us not let the world be defined by the destruction wrought by one virus, but illuminated by billions of hearts and minds working in unity.
With the absence of a flu vaccination last year, I did not take a flu shot; but there is still some immunity that carries over from year to year; but about every 30 years, there is a major change in the genetics of the flu virus.
An inefficient virus kills its host. A clever virus stays with it.
The Zika virus invades and disrupts the development of the fetal brain, but the effects on the brains of infants and young children are unknown.
It's the advantage of the virus to spread, and you can only spread when you infect people and they infect other people without necessarily killing them. So if you had 100 percent mortality, the potential pandemic would almost self-eliminate itself.
The unique nature about the influenza virus is its great potential for changes, for mutation.
When Russia's intelligence agencies obtained some of the National Security Agency's secrets about its own cyberweapons, it appeared to do so by manipulating a virus protection program sold by Kaspersky, a Russian firm.
When an animal is infected, either naturally or by experimental injection, with a bacterium, virus, or other foreign body, the animal recognises this as an invader and acts in such a way as to remove or destroy it.
Violence and irrationality were so long and thoroughly cultivated among the Irish, and so perfectly ingrained into their nature, that modern civilization has as yet been unable to extract the virus.
I started with Apple, in a pre-Windows era when PCs seemed to involve more of a learning curve. But the fact that I'm yet to acquire so much as a single virus still seems a very good thing.
Viruses have to live somewhere. They can only replicate in living creatures. So, when the Ebola virus disappears between outbreaks, it has to be living in some reservoir host, presumably some species of animal.
The mutating virus of multiculturalism has escaped its breeding ground in elite universities and is now running rampant across popular culture, entertainment, and politics.
New technologies can be used for destructive purposes. The answer is to develop rapid-response systems for new dangers like a bioterrorist creating a new biological virus.
Language is a virus from outer space.
