Ralph R. Frerichs is professor emeritus of epidemiology at UCLA where he was active as a full-time faculty member in the School of Public Health for 31 years and as the Epidemiology department chair for 13 years, before retiring in late 2008. [1] Both at UCLA and in international workshops he taught epidemiologic methods, the use of rapid community-based surveys, [2] [3] epidemiologic simulation models for focused research, and screening and surveillance methods for HIV/AIDS and other diseases. [4] [5]

In addition, he consulted on epidemiological and management-related issues with many international agencies including the Albert Schweitzer Foundation, Population Council, UN, WHO, USAID and CDC in 16 countries:Colombia, Bolivia, Honduras, Brazil, Kenya, Bangladesh, Myanmar (formerly Burma), Thailand, Laos, Cambodia, Vietnam, Indonesia, Philippines, Mongolia, Federated States of Micronesia and the country of Georgia.

Since retirement, he authored Deadly River: Cholera and Cover-up in Post-Earthquake Haiti (Cornell University Press, 2016), [6] is engaged in panoramic photography, [7] and continues to manage the popular John Snow website, [8] which he created to honor the historical father of epidemiology, known for his insightful research on cholera.

Life and career

Frerichs was born on October 3, 1942, in Berlin, Germany, the son of physicist Rudolf Frerichs known for development of the cadmium-sulfide photoconductive cell, [9] and artist and writer Gisela Frerichs. The family moved to the United States in 1947–48, where his father joined the faculty of Northwestern University in Evanston, Illinois. [9] Frerichs obtained his DVM in 1967 from the University of Illinois College of Veterinary Medicine at Urbana-Champaign. Following two years in Birmingham, Alabama, as captain in the US Army Veterinary Corp, he obtained the MPH and DrPH (epidemiology) in 1970 and 1973, respectively from Tulane University School of Public Health and Tropical Medicine in New Orleans. While working on his doctoral dissertation (development of a computer simulation model for the control of urban rabies) [10] [11] he was both a research associate with the International Center for Medical Research and Training in Cali, Colombia and an instructor at Tulane University. [12] After graduation, Frerichs became assistant professor of preventive medicine at the LSU School of Medicine in New Orleans, [13] and epidemiologist for the Bogalusa Heart Study, a longitudinal study of cardiovascular disease risk factors in children in the biracial community of Bogalusa, Louisiana. During his LSU years from 1973 to 1977, his publication topics included pediatric levels of blood cholesterol and triglyceride levels, [14] lipoproteins, [15] blood pressure, [16] hemoglobin. [17] and obesity. [18]

In early 1978, Frerichs joined the epidemiology faculty at UCLA, rising through the ranks from assistant to full professor, while expanding his research interests both domestically and internationally. Nationally, he focused on airport noise and mortality, [19] mental depression, [20] spatial patterns of cardiovascular disease mortality, [21] and the health impact of recycled wastewater. [22] Globally, his research included health status measures and costs of care in Bolivia, [23] microcomputer applications in Bangladesh, [24] Burma [25] and elsewhere, [26] and pediatric health indicators in Burma. [27] While in Burma (later renamed Myanmar), he developed an approach for quickly conducting community-based surveys, [28] which soon became a component of international surveillance systems. Several years later he introduced a more advanced form of the rapid survey method for use in the United States. [29]

Becoming increasing involved with HIV/AIDS, he realized the need for a simple saliva test to assist screening and surveillance activities. [30] His 1994 call in The Lancet for personal HIV screening in developing countries invoked controversy during a time when detection was viewed as worse than the disease, [31] as did his Epidemiology commentary on HIV winners and losers, [32] and his AIDS article on the harm of not permitting personal HIV screening in developing countries. [33] Controversy continued in his retirement years, when he wrote of the United Nations involvement in the origin of the world's largest cholera epidemic in Haiti, [34] later expanded in his book Deadly River featuring French epidemiologist Renaud Piarroux. [35]

Honors included the Delta Omega Public Health Honor Society (1970); the American Epidemiological Society (1982, an honorary society of epidemiologists since 1927); [36] UC Berkeley's 1988 invitation as Ralph Sachs Visiting Scholar for his work in computer technology in developing countries; outstanding alumnus in 1992 of Tulane's School of Public Health and Tropical Medicine; [37] and in 1997 the Prestigious Plaque for HIV/AIDS Education from Thailand's Ministry of Public Health and Bangkok's College of Public Health at Chulalongkorn University. [1]

Frerichs has two adult children, Peter [38] and Christine, [39] and is married to Rita Flynn, following the death of wife Marcy after 34 years of marriage. The couple resides in Southern California at the base of the San Gabriel Mountains.

Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea lasting a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure.

<span class="mw-page-title-main">Field epidemiology</span>

Field Epidemiology is the application of epidemiologic methods to unexpected health problems when a rapid on-site investigation is necessary for timely intervention. A more expansive definition is: The practice of Epidemiology in the field. Work is done in communities often as a public health service and as part of government or a closely allied institution. Field epidemiology is how epidemics and outbreaks are investigated, and is used to implement measures to protect and improve the health of the public. Field epidemiologists must deal with unexpected, sometimes urgent problems that demand immediate solution. Its methods are designed to answer specific epidemiologic questions in order to plan, implement, and/or evaluate public health interventions. These studies consider the needs of those who will use the results. The task of a field epidemiologist is not complete until the results of a study have been clearly communicated in a timely manner to those who need to know, and an intervention made to improve the health of the people.

Molecular epidemiology is a branch of epidemiology and medical science that focuses on the contribution of potential genetic and environmental risk factors, identified at the molecular level, to the etiology, distribution and prevention of disease within families and across populations. This field has emerged from the integration of molecular biology into traditional epidemiological research. Molecular epidemiology improves our understanding of the pathogenesis of disease by identifying specific pathways, molecules and genes that influence the risk of developing disease. More broadly, it seeks to establish understanding of how the interactions between genetic traits and environmental exposures result in disease.

The third cholera pandemic (1846–1860) was the third major outbreak of cholera originating in India in the 19th century that reached far beyond its borders, which researchers at University of California, Los Angeles (UCLA) believe may have started as early as 1837 and lasted until 1863. In the Russian Empire, more than one million people died of cholera. In 1853–1854, the epidemic in London claimed over 10,000 lives, and there were 23,000 deaths for all of Great Britain. This pandemic was considered to have the highest fatalities of the 19th-century epidemics.

In epidemiology, ecological studies are used to understand the relationship between outcome and exposure at a population level, where 'population' represents a group of individuals with a shared characteristic such as geography, ethnicity, socio-economic status of employment. What differentiates ecological studies from other studies is that the unit analysis being studied is the group, therefore inferences cannot be made about individual study participants. On the other hand, details of outcome and exposure can be generalized to the population being studied. Examples of such studies include investigating associations between units of grouped data, such as electoral wards, regions, or even whole countries.

There are a number risk factors for tuberculosis infection; worldwide the most important of these is HIV. Co-infection with HIV is a particular problem in Sub-Saharan Africa, due to the high incidence of HIV in these countries. Smoking more than 20 cigarettes a day increases the risk of TB by two to four times while silicosis increases the risk about 30 fold. Diabetes mellitus is also an important risk factor that is growing in importance in developing countries. Other disease states that increase the risk of developing tuberculosis are Hodgkin lymphoma, end-stage renal disease, chronic lung disease, malnutrition, and alcoholism. A person's genetics also play a role.
