Elie Metchnikoff Quotes

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.

Another interesting field, which is my own, is cofactors, not only to the disease but also to transmission. I am still puzzled by the fact that you get more sexual transmission in some ethnic populations. One way to answer this is to look for genetic factors.

College campuses are a focus of prevention efforts for meningococcal disease because of the increased incidence of the disease during adolescence and young adulthood, as well as transmission from crowded living conditions and social behaviors common among college students.

Autoimmunity is probably the next frontier. The majority of cases of autoimmune disease result from a complex genetic problem that has environmental influences. It is a colossal task for the immune system to maintain tolerance to self and yet be ready to react to everything in the world around us.

Think about all kinds of infectious diseases, like mumps or measles or chicken pox. When a virgin population encountered those pathogens, it ravaged the population, and now they're childhood diseases, and eventually they won't even be that. That's our relationship with bacteria, going through time.

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.

If you really want to isolate a disease, then you have to isolate the people who carry it.

The pandemic of AIDS is a gender-based disease.

I burned out on AIDS and did no AIDS work for a couple of years. I was so angry that people were still getting this disease that nobody can give you - you have to go out and get it!

Influenza is a serious disease. Kids die of influenza, both in Japan and the United States, and if you give a drug to people who are at risk of dying, there will be people who die who got the drug,... There is no signal the drug is doing it as opposed to the disease.

In the 19th century, smallpox was widely considered a disease of filth, which meant that it was largely understood to be a disease of the poor. According to filth theory, any number of contagious diseases were caused by bad air that had been made foul by excrement or rot.

A person's health isn't generally a reflection of genes, but how their environment is influencing them. Genes are the direct cause of less than 1pc of diseases: 99pc is how we respond to the world.

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.

Many people assume the diseases that kill us are pre-programmed into our genes. High blood pressure by 55, heart attacks at 60, maybe cancer at 70, and so on... But for most of the leading causes of death, our genes usually account for only 10-20 per cent of risk.

Studies of immigration show that this resistance to heart disease is not just something in African or Chinese genes. When people move from low-risk to high-risk areas, disease rates skyrocket as they adopt Western diets and lifestyles.

Genes work with probabilities; they don't work with certainties. So most things that you're looking at with these genetic tests, it's not like you're condemned to automatically get the disease or the syndrome. There's a lot of factors in play there.

Unequal development in different countries in the promotion of health and control of disease, especially communicable disease, is a common danger.

Malaria in Africa did not come from bad governance. It came from bad mosquitoes.

People are used to dealing with risk. You are told if you smoke, you are at higher risk of lung cancer. And I think people are able to also understand, when they are told they are a carrier for a genetic disease, that is not a risk to them personally but something that they could pass on to children.

There's clearly things you can do in your environment to try to prevent disease, and I want to know what those things are.

The poor lifestyle I had been leading made my body susceptible to diseases. Had it not been cancer, some other malady would have struck me.

Individuals in very small groups are about the only thing that is free of the disease of the embedded growth obligation.

I don't suffer from SCD myself, but I do carry the gene. This means that if I married another person who carried the gene, there would be a danger our children would suffer from the disease.

[H]as the CDC ever published a story about the dangers of catching diseases when you sleep with illegal aliens?
