Quotes About Epidemiology

what scientists call zoonotic disease was little known in the Americas.

The most dangerous infections of humans have always been those which have emerged from other species.

He estimates the number of deaths worldwide as 100 million, a larger number than the conventional estimate of 20 to 40 million. But, he said, 20 million people died in India alone, making it impossible for the 20 to 40 million figure to be correct.

Epidemiologists study patterns in order to combat infection. Stories about epidemics follow patterns, too. Stories aren't often deadly, but they can be virulent: spreading fast, weakening resistance, wreaking havoc.

We see new things all the time. We see new retroviruses out there - which is the category that HIV falls into - and we're very, very concerned because this is the part of the world where HIV jumped from chimpanzees to humans.

I earned a Master's degree in Epidemiology from the Stanford University School of Medicine in 2009.

To comprehend the interactions between Homo sapiens and the vast and diverse microbial world, perspectives must be forged that meld such disparate fields as medicine, environmentalism, public health, basic ecology, primate biology, human behavior, economic development, cultural anthropology, human rights law, entomology, parasitology, virology, bacteriology, evolutionary biology, and epidemiology.

If we vaccinate well, if we increase those vaccination rates, we can stop measles just as we stopped it before.

For example, typhus was initially transmitted between rats by rat fleas, which sufficed for a while to transfer typhus from rats to humans. Eventually, typhus microbes discovered that human body lice offered a much more efficient method of traveling directly between humans. Now that Americans have mostly deloused themselves, typhus has discovered a new route into us: by infecting eastern North American flying squirrels and then transferring to people whose attics harbor flying squirrels.

If we do the kind of common-sense public health measures we know work, we ought to be able to stop it from being a global pandemic.

As a single case from half a century ago, Sybil Exposed cannot tell us anything about the reliability, validity, etiology, epidemiology, or typical treatment outcome of a mental disorder. Nathan's alternative theory of pernicious anemia is implausible and supported by no corroborating evidence; Debbie Nathan advocates a hypothetical explanation of Shirley's pre-1945 symptoms that is less evidence based than the trauma dissociation theory she rejects.

The vast preponderance of evidence in modern epidemiology shows that those who eat more whole plant foods and fewer animal products and processed foods have lower rates of chronic disease and longer lifespans.

I think the first general point to make from epidemiological studies across millions of people is the following - that short sleep predicts a shorter life. It predicts all cause mortality.

Since most of the transmission is sexual transmission, you have a regional or local response to the virus.

The best and largest cohort studies in nutritional epidemiology, such as the Adventist Health Study, the Iowa Women's Health Study, the Nurses' Health Study, the Physicians' Health Study, and the CARE Study all confirm that eating nuts and seeds is associated with a 30–50 percent decreased risk of CAD death, primarily sudden cardiac death, and dramatic decreases in all-cause mortality.

Epidemiological evidence suggests that a new influenza virus originated in Haskell County, Kansas, early in 1918. Evidence further suggests that this virus traveled east across the state to a huge army base, and from there to Europe. Later it began its sweep through North America, through Europe, through South America, through Asia and Africa, through isolated islands in the Pacific, through all the wide world.

And West Nile will never be a major threat; it is not a disease that will ever explode through the human population. Yet it was receiving more research dollars than influenza.

The lowest estimate of the pandemic's worldwide death toll is twenty-one million, in a world with a population less than one-third today's. That estimate comes from a contemporary study of the disease and newspapers have often cited it since, but it is almost certainly wrong. Epidemiologists today estimate that influenza likely caused at least fifty million deaths worldwide, and possibly as many as one hundred million.

That's because I believe in what I call consequential epidemiology. That is, by attempting to change what could happen if we don't act, we can positively alter the course of history, rather than merely record and explain it retrospectively.
