The influenza virus and HIV use this strategy.

All subtypes (but not all strains of all subtypes) of influenza A virus are adapted to birds, which is why for many purposes avian flu virus is the influenza A virus.

But even a mild influenza virus kills a lot of people, especially those with other medical problems.

It is a highly virulent influenza virus such as this that is devastating chickens in parts of Asia.

But if an influenza virus jumps from, say, ducks to chickens, there may be lethal consequences.

That influenza virus has also jumped from the chickens to those who look after them, killing some people.

A well understood example is that of influenza viruses in wild fowl, where the virus causes infections that are hard to detect.

My anti virus let a virus through.

Scientists long anticipated that an influenza virus will spread as now appears to be happening in Asia from wild birds to humans, causing a pandemic.

The chronic fear of health authorities is that, by chance, another avian influenza virus will mutate and spread from person to person to spawn a global pandemic.

It's probably a virus.

It's not a virus.

A virus has either a DNA or an RNA genome and is called a DNA virus or an RNA virus, respectively.

Why not? Every plant virus, every insect virus, every marine virus.

A virus infected Tom's computer.

A virus infected Tom's computer.

Could it be a virus?

It must be a virus.

The well studied tobacco mosaic virus is an example of a helical virus.

Virus Killer

My pen drive has a virus.

We know from influenza that a new epidemic can suddenly appear just as an older one is fading, if a new form of the virus appears, or if some environmental factor increases the contagion rate.

Here we come. And that was the influenza.

Virus protection and virus development constitute an uneven arms race.

Aren't you afraid of catching a virus?

This virus was engineered in a lab.

Kits for rapid diagnosis of influenza infection already exist.

And so we use a virus that's a non toxic virus called M13 bacteriophage that's job is to infect bacteria.

That looks like the work of a virus.

I can't open this message. A virus, maybe?

The virus can easily infect a healthy person.

A virus is a string of nucleic acid with attitude.

I think I have a virus on my computer.

This specificity determines the host range of a virus.

It is also a crisis of emerging infectious diseases (EID s), such as HIV in humans, Ebola in humans and gorillas, West Nile virus and Avian Influenza in humans and birds, chytrid fungi in amphibians, and distemper in sea lions.

Plant virus particles or virus like particles (VLPs) have applications in both biotechnology and nanotechnology.

So one part of the virus grabs a carbon nanotube.

Tatoeba is ill. It got Tom, a highly infectious virus.

I think that this computer is infected by a virus.

Influenza vaccine supplies should be increased so that more individuals are inoculated.

Ebola virus under an electron microscope.

The virus makes him very feverish.

The virus is starting to mutate.

When the adaptive immune system of a vertebrate encounters a virus, it produces specific antibodies that bind to the virus and often render it non infectious.

Yesterday, Negroponte was talking about viral telecommunications but what's a virus?
