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.
It is important to note that there exist vast gender differences in the global role of papillomaviruses in human cancers. This is mainly due to the role of this virus family in the induction of cancer of the cervix.
I'm actually pretty scientifically interested. I have a lot of friends who are doctors, so the idea of the virus and the synapses in the brain and how the nervous system works was actually all pretty familiar to me.
People would ask, 'Why is your vocal cord paralyzed?' I said it was a virus. I didn't say it was an elective procedure to add hair to the front of my head. It was embarrassing. There's an embarrassing element to that.
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.
I've had two neck surgeries, a back surgery, three knee surgeries, eye surgery, but I keep bouncing back. I won't go away - kind of like a virus. I don't go away. I keep coming back stronger and stronger. I'm contagious.
In the years when HIV was a killer, any parent of an openly gay person was terrified. I knew my mother well enough that she would spend every day praying that I didn't come across that virus. She'd have worried like that.
All these things that we've contemplated, whether it's space travel or solutions to diseases that plague us, Ebola virus, all of these things would be a lot more tractable if the machines are trying to solve these problems.
The more cases of Ebola infection we have, the more chances there are for the virus to mutate in a particular way that adapts it well to living in humans, replicating in humans, and perhaps transmitting from human to human.
One of the things that's particularly nefarious about Ebola is that it continues to live in a dead person for some period of time after death. A person who's been dead for a day or two may still be seething with Ebola virus.
The largest outbreak of bird flu in American history was an H5N2 virus, which led to the deaths of 17 million domestic birds and cost the nation more than $400 million during an outbreak in Pennsylvania that started in 1983.
Some of the most vulnerable people to getting the SARS virus are health care providers. The general public, walking in the street, there is really not that much risk at all. It's a very, very low risk - a very, very low risk.
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.
Containment doesn't work. Containment does buy time. It could slow. It very well could slow the spread. But while you're slowing the spread, you better be doing something in parallel to be prepared for when that virus breaks out.
Peter Jennings came to us and said to make a PSA, 'Let's Talk About AIDS.' But I was naive about how the virus is contracted - until Magic Johnson came out. I'd stereotyped it, thinking it was a gay disease, a white man's disease.
Maybe I should mention it: I was not from the beginning mainly interested in papilloma virus; I was mainly interested in infectious agents in human cancer. So papilloma viruses came up as the most likely candidate from my viewpoint.
What we worry about is actually the potential negative aspects of wearing a mask, where people are not protecting their eyes, or other aspects of where the virus could enter your body, and that gives you a false sense of confidence.
I knew the HIV virus was something anyone could get but also believed the chances were very slim... I honestly believed I had a better chance of winning the lottery than contracting this disease. I have never been so wrong in my life.
If a vaccine works, then the vaccinators might conceivably set up what's known as ring vaccinations around Ebola hot spots. In this technique, medical workers simply vaccinate everybody in a ring, miles deep, around a focus of a virus.
Gorillas are in danger of being wiped out by the Ebola virus. I feel like we have limited time to get to know them and understand them and they're going to disappear - that's terrifically sad. Wouldn't it be great if we could stop that?
The launch of phase 1 Ebola vaccine studies is a first step in developing a vaccine that could be licensed and used in the field to protect not only the front line health care workers but also those living in areas where Ebola virus exists.
When I was 5 and my sister was 3, we went on a family trip, and she ate cheese off the floor at an airport. My mother, a germaphobe, got very upset. My sister, of course, got a stomach virus, and ever since then, I have an aversion to cheese.
An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.
Supporting American technology companies is one of the most patriotic things you can do - the technology industry is the reason our country has such a high-standard of living and why we can afford to spread the democracy virus around the globe.
There are many different types of racism from people of different colours and nationalities. There is no vaccine to fight this and no antibiotics to take. It's a dangerous and infectious virus which is strengthened by indifference and inaction.
Ebola isn't a respiratory virus. It doesn't spread through the airborne route. So it's not likely to spread like wildfire around the world and kill tens of thousands or hundreds of thousands of people. That's what I think of as the next big one.
But what has been pretty good about the coronaviruses in general is they keep their structural pieces very similar. What do I mean by that? There's certain - the outer coat, the envelope, and the inside part of the virus has stayed very constant.
I wanted to build something that was a system - that was mechanical and would propagate itself like a virus. I needed a way for it spread from person to person, and the best way to do that was trying to get someone to get their friends to sign up.
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 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.
There are other countries that if you had a preexisting condition, and let's say the virus caused you to go to the ICU and then have a heart or kidney problem, some countries are recording as a heart issue or a kidney issue and not a COVID-19 death.
I wanted to play around with the format, really tear it to pieces and shake it up. For example, if Mitch saves someone from drowning, and that person then goes out and releases a virus that kills a million people. Imagine the moral implications of that.
Every one of us has a small but critical part to play in the battle against coronavirus. From washing our hands to wearing a face covering on public transport and in shops, every time we take one of these actions, we push the virus further into retreat.
Thankfully, I found a doctor at Presbyterian Hospital in New York, Scott Hammer, who diagnosed my chronic fatigue as the Epstein-Barr virus, and the medication I took either helped jump-start my immune system or made the virus dormant. I was very lucky.
Even after being diagnosed with Covid-19, Bolsonaro fails to take this virus seriously and is directly targeting vulnerable indigenous communities by failing to provide them with adequate funding to address this pandemic. It's an attack on human rights.
Just as the only reservoir for the typhus virus in nature is provided by man, so the only vector of infection is the louse. The bite of the louse is not virulent immediately after the infecting meal. It becomes so only towards the 7th day following infection.
I don't think you should be ashamed of anybody that you know that has AIDS. You should stand as close to them as you can and help them out as much as you can. I'm a strong believer in that and that's why I try to do that for everyone I know that has the virus.
There's no one place a virus goes to die - but that doesn't make its demise any less a public health victory. Throughout human history, viral diseases have had their way with us, and for just as long, we have hunted them down and done our best to wipe them out.
We did more to thwart Iran's nuclear ambitions with a computer virus than we ever could have with bombs (and we did still more with diplomacy - the abandonment of which is also bad for our military, because militaries can only stop a problem, not fix a problem).
The Strandbeest is a self-replicating meme, a brain virus. It infects the student's brain. In fact, the Strandbeest abuse students for their reproduction. For two years, this reproduction fell into a flow acceleration. Now, 3D printers produce walking mini Strandbeests.
When the AIDS epidemic broke, because I happened to be a science nerd and knew a lot about viruses and a lot about that virus at the time, I felt a moral obligation to go out and try to stem the fear and get out and explain to people what the disease was and how it worked.
The amount of time it takes to recover from the coronavirus differs widely. Some people will get the virus and have no symptoms at all, other people will have mild symptoms like a low-grade fever or a mild cough and others will get really ill and will need to be hospitalized.
Nation states that are used to imposing capital controls will face a quandary: ban cryptocurrencies and live in the technology dustbin; enable them, and this virus - this religion, this protocol - will enable the free flow of money and language, along with packets, around the globe.
Do you remember the first three years of Steam? People absolutely hated that Valve forced you to launch their game through what some people called a virus at the time, which was the Steam client. But Steam led the digital distribution revolution: it was the first across all platforms.
I decided to pursue graduate study in molecular biology and was accepted by Professor Itaru Watanabe's laboratory at the Institute for Virus Research at the University of Kyoto, one of a few laboratories in Japan where U.S.-trained molecular biologists were actively engaged in research.
The nature of a protective immune response to HIV is still unclear. Because in a very, very unique manner, unlike virtually any other microbe with which we're familiar, the HIV virus has evolved in a way that the immune system finds it very difficult, if not impossible, to deal with the virus.
Historical records show that smallpox was a human scourge for thousands of years. The virus produces high fever, severe back pain and scarring eruptions of flat red spots on the skin that turn into pustules and then into scabs - a two-week process during which the disease is highly contagious.
The 50th Earth Day was always going to be special, but the coronavirus pandemic has made it even more so. The unprecedented steps the world has taken to slow the spread of the virus have dramatically reduced the number of cars on the road, planes in the air, and oil being pulled from the ground.
What if life is not carbon-based? Can life exist as a gas or a plasma? Could planets or stars in some sense be alive? What about an interstellar cloud? Could life exist on such a small or large scale, or move so fast or so slowly that we wouldn't recognize it? Could you have an intelligent virus?
See, Ebola, like all threats to humanity, it's fueled by mistrust and distraction and division. When we build barriers amongst ourselves, and we fight amongst ourselves, the virus thrives. But unlike all threats to humanity, Ebola is one where we're actually all the same. We're all in this fight together.
