Charles Jules Henry Nicole Quotes

Left to their own devices, epidemic diseases tend to follow the same basic process: A virus or bacteria infects a host, who typically becomes sick and in many cases dies. Along the way, the host infects others.

High levels of stress can lead to weakened immunity, rendering animals much more susceptible to disease. This makes the average poultry factory farm a hotbed for outbreaks of avian flu.

For the animals, they came from the University in Uppsala and all different kinds of clinics here.

Experiments suggest that if one particle of Ebola enters a person's bloodstream, it can cause a fatal infection. This may explain why many of the medical workers who came down with Ebola couldn't remember making any mistakes that might have exposed them.

Even if it had not been possible to reproduce the disease in animals and consequently to verify the hypothesis, this simple observation would have been sufficient to demonstrate the way in which the disease was propagated.

It's true that my research expertise is in biology: for example, the Ebola virus, the Marburg virus, and monkey pox, and not bacteriology as in the case of the anthrax organism. It's also true that I have never, ever worked with anthrax in my life. It's a separate field from the research I was performing at Fort Detrick.

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.

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.

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.

Epidemics follow patterns because diseases follow patterns. Viruses spread; they reproduce; they die.

A carrier with a venereal disease can have many partners, but only those whose mental and physical immune systems are weak will be susceptible to it.

The fact that I was fortunate enough to escape contagion, in spite of frequent, sometimes daily contacts with the disease, was because I soon guessed how it spread.

People may have said that without symptoms, you can't transmit Ebola. I'm not sure about that being 100 percent true. There's a lot of variation with viruses.

The belief is growing on me that the disease is communicated by the bite of the mosquito... She always injects a small quantity of fluid with her bite - what if the parasites get into the system in this manner.

I demonstrated the characteristics of experimental fever. It appears after an incubation period which is never less than five days. It follows the same pattern as natural fever in man, but is of shorter duration and less pronounced.

Nobody would have me in their laboratory for five minutes. I couldn't cut up a frog, and I certainly couldn't perform surgery. I'm better at making it possible for other people.

From the practical point of view, the susceptibility to infection of the guinea pig proved to be the most useful step forward. Today, all laboratories use this animal for preserving the virus.

If a bacterium is trying to infect you, it won't secrete alone, because your immune system will block it. Bacteria will hide until they can all act together and make an impact.

Of all the problems which were open to me for study, typhus was the most urgent and the most unexplored. We knew nothing of the way in which contagion spread.

In today's world, new infections and diseases can spread across the country and even across the world in a matter of days, or even hours, making early detection critical.

On some peculiar pigmented cells found in two mosquitoes fed on malarial.

It's extremely likely that the people who have never been exposed to a human who has leprosy, it's very likely they got leprosy from exposure to an armadillo.

Anthrax, it's something that gets you sick, it's horrible, strong. It's a heavy-metal band name if there ever was one.

Infectious disease exists at this intersection between real science, medicine, public health, social policy, and human conflict. There's a tendency of people to try and make a group out of those who have the disease. It makes people who don't have the disease feel safer.

Staph lives on skin. That's the reason why many infections start as a boil.
