OBJECTIVES AND PHILOSOPHY

OBJECTIVES AND PHILOSOPHY

Infectious and communicable disease control provided the model for public health. Unfortunately, even the communicable diseases today do not respond so easily to single interventions such as immunization or water purification. The modes of transmission and the multiplicity of factors influencing host and antimicrobial resistance make the viral diseases and the remaining bacterial diseases of our time less responsive to the environmental controls possible against some of the scourges of the past. New models of disease control are contrasted in this chapter with classical models. Our overall objective in this chapter is to develop an understanding of the principles of communicable disease control.


OVERVIEW

Basic concepts of infection, contamination and related processes of disease transmission are presented first. The epidemiology and classification of infectious diseases follows. The saga of smallpox eradication is a tale of victory, but with tuberculosis and some sexually transmitted diseases we seem to be losing ground. The concepts of host resistance and the agent-host-environment triad suggest specific strategies for control of communicable diseases.

Panel Urges Switch to Polio Shots. ATLANTA (AP, June 17, 1999) – A federal panel recommended Thursday that the oral polio vaccine that was first given to baby boomers on a sugar cube be abandoned in favor of the injected version to reduce the risk of contracting the paralyzing disease from the serum itself. The oral vaccine, developed by Dr. Albert Sabin, has been used for nearly four decades and played a major role in the elimination of polio. But because it is made with a live virus, it causes about eight people in the United States each year to become infected with polio. In contrast, the injectable vaccine developed by the medical pioneer Dr. Jonas Salk in the 1950s relies on a killed virus. Salk had long insisted his injectable vaccine was safer. However, other scientists said it was not as effective at providing lifelong immunity.

Weakened AIDS Virus Still Damaging.
(AP, June 3, 1999) - Several people in Australia who caught a weakened form of HIV in the early 1980s are showing AIDS-like damage to their immune systems, a development with disappointing implications in the search for a vaccine. Between 1980 and 1984, 13 people in Australia received blood donated by an HIV-infected man, and eight of them caught the virus. When none got sick, researchers analyzed the virus and found that it was missing a working copy of a gene called nef, which boosts HIV reproduction. Over the years, three of the infected people died of other causes, and none has gotten AIDS. Some researchers had hoped that a vaccine modeled on the weak virus could be an effective AIDS vaccine, protecting people for life without making them sick.

Meningitis Vaccine Study Released.
CHICAGO (AP, May 26, 1999) – Researchers have found that college students living on campus are about three times more likely to contract meningitis infections than classmates who live off campus. The analysis released Tuesday in The Journal of the American Medical Association was performed by researchers at Johns Hopkins University School of Public Health. The findings prompted the American College Health Association to renew its 1997 recommendation that all college students consider getting vaccinated against meningococcal disease, which can cause meningitis or an overwhelming and often fatal blood infection called meningococcemia. Meningococcal disease afflicts 125 to 175 college students annually and kills 15 to 20 of them, according to public health estimates.


Flu Season Was Deadlier Than Usual.
ATLANTA (AP, May 14, 1999) – The U.S. flu season was apparently deadlier than usual this year, the government reported Thursday. The flu season runs from October through mid-May. The Centers for Disease Control and Prevention does not know yet how many people died this season from the flu. However, in an average flu season, there are about 20,000 deaths, and about 30,000 when the Type A-H3N2 virus hits – as it did this year, the CDC said. The deadliest flu season in the past decade was 1989-90, when about 44,000 people died. This year, the flu season got off to a slow start, with few cases until mid-January. By February, the flu was widespread in 40 states. The outbreaks had tapered off by mid-April. The strain most prevalent was Type A Sydney.


India Cites Tuberculosis Threat.
NEW DELHI, India (AP, Mar. 17, 1999) - With nearly half of its 980 million people infected with tuberculosis, India has obtained a $144 million loan from the World Bank to fight the disease. Using the loan, the government hopes to reach 271 million people using the directly observe treatment strategy (DOTS), G.R. Khatri, a deputy director general in the health ministry, said at a news conference Wednesday. Globally, tuberculosis is the biggest killer of young people and adults. A half million people die of it every year in India. The death rate has come down to five per 500,000 patients from 53 per 500,000 since India adopted the DOTS strategy 15 years ago, Khat ri said. At present, 13.9 million people are covered by DOTS.


Legionnaire's Disease Hits Netherlands
. AMSTERDAM, Netherlands (AP, Mar. 16, 1999) - An outbreak of lethal Legionnaires' disease at a Dutch flower show killed another victim Tuesday, raising the death toll to 10, Dutch media reported. A government spokeswoman could not immediately confirm the reports of the latest death. The bacterial infection was traced to a flower show in Bovenkarpsel, 40 miles north of Amsterdam. On Monday, the government confirmed only that five deaths were due to Legionnaires' disease, although four others who had visited the show since have died. Just over 40 people were believed to have been infected with the pneumonia-like illness. Legionnaire's disease was named after an outbreak at a 1976 convention of the American Legion in Pennsylvania. The bacteria that are believed to cause the illness are found in soil and grow in air-conditioning ducts, storage tanks and rivers.


Blacks Getting AIDS At Record Rates
. WASHINGTON (AP, Feb. 26, 1999) - Black Americans are becoming infected with AIDS at record rates, receiving poorer care than whites and dying faster. Now, almost two decades into the AIDS epidemic, about 1,000 health care providers and activists gathered for the first medical conference on AIDS among black Americans - a frantic hunt for ways to fight the exploding racial divide. AIDS in the United States is evolving from a disease that once mostly affected white homosexuals into one largely of poor blacks, often infected from dirty drug needles or heterosexual encounters.


New Test Developed For Blood Supply.
WASHINGTON (AP, Mar. 5, 1999) – The nation's blood supply is set to undergo a revolution in safety testing: Blood banks next week begin phasing in sophisticated genetic fingerprinting tests in an attempt to wipe out the few dangerous viral infections that occasionally slip into transfusions. "This is the biggest thing that's happened in blood banking since the HIV test," said James MacPherson of America's Blood Centers, which collects about half of the nation's donated blood. Blood already is safe. But the new genetic technology, which should encompass all blood transfusions by September, promises to make it even safer.


Sudan Meningitis Epidemic Spreads.
NAIROBI, Kenya (AP, Mar. 4, 1999) – A meningitis epidemic spreading through Sudan has reached alarming levels in six states, killing at least 233 people, the International Federation of Red Cross and Crescent Societies reported Thursday. The aid agencies said 1,762 cases have been reported and warned that unless vaccination campaigns are accelerated, the disease will spread further. Vaccination campaigns are under way, but a vaccine shortage has prevented comprehensive coverage in the worst-affected states and people have begun to panic, it said. Streams of frightened people are now besieging aid offices, asking for vaccinations.


Kenya: Campaign Against Typhoid.
(The Nation, Feb. 25, 1999). At a workshop in Nairobi, the Kenya Medical Association (KMA) announced the launch of a national public awareness campaign against typhoid. One out of three Kenyans who gets infected with the disease eventually dies, a consultant microbiologist said. The World Health organization (WHO) estimates that 16 million people worldwide are afflicted by typhoid annually, resulting in about 600,000 deaths (http://www.who.int/gpv-dvacco/disease/typhoid_fever.htm). Typhoid is difficult to diagnose, a problem made worse in Kenya by quacks running laboratory clinics. The first line of action recommended by WHO is to avoid faecal contamination of water sources. The meeting urged Rhone Poulenc to lower the price of their typhoid vaccine to make it affordable to a majority of Kenyans. http://www.africanews.org/east/kenya/stories/19990225_feat18.html


Mandatory Hepatitis Shots Urged.
ATLANTA (AP, Feb. 18, 1999) - A U.S. federal health group wants 11 Western states with a high incidence of hepatitis A to require that children be vaccinated. Children are one of the highest risk groups for hepatitis A, the Atlanta-based Centers for Disease Control and Prevention's advisory committee on immunization said Wednesday. The committee recommended that states with at least 20 cases out of every 100,000 people - twice the national average for hepatitis. A cases between 1987 and 1997 - implement routine vaccinations. Those states currently are Arizona, Alaska, California, Idaho, Nevada, New Mexico, Oklahoma, Oregon, South Dakota, Utah and Washington.


Health Promoting Hospitals
The International WHO Network of Health Promoting Hospitals was set up in 1991 to support hospitals as the central institution of the health care sector to become a more health promoting setting. Health Promoting Hospitals focus on promoting health for patients, staff and the population in the community and they are trying to move towards a "healthy organization" (in a metaphorical sense). In the last years the experiences of several projects and activities brought about considerable expertise and knowledge. Recently the Ludwig Boltzmann-Institute for the Sociology of Health and Medicine as        Co-ordinating Centre of the network set up a homepage: http://www.univie.ac.at/hph/.


Mozambique: Cholera Outbreak.
(Arkia News Network, Feb. 5, 1999)- Cultural and religious beliefs are hampering the control of the cholera epidemic in Mozambique. Go to: http://www.planetark.org/dailynewsstory.cfm/newsid/13706story.htm Isolation of cholera patients is not adhered to because relatives want to support them and end up getting infected as well. In northern Mozambique people don't use latrines, increasing the risk of the disease. In reaction to a series of violent incidents in Nampula, police detained 99 people accused of participating in a campaign of agitation against health workers involved in combating the cholera outbreak. The agitation was attributed partly to rumors deliberately spread by opposition political parties. Minister of Health, Aurelio Zilhao, said that cholera could be ended or reduced only with the improvement of the water supply systems and hygienic measures, especially in the rural areas. http://www.africanews.org/south/mozambique/stories/19990205_feat1.html


Uganda: Kampala Cholera Campaign.
(International Federation of Red Cross and Red Crescent Societies, Press Release, 4 February 1999)- The Red Cross is seeking UGS 50 million (EUR 32,200) for a cholera campaign in Uganda to avoid a repetition of last year's outbreak when 100-150 cases a day were registered in Kampala. As part of the National Cholera Task Force, the Red Cross has deployed 50 volunteers to provide community health education, chlorinate water sources, locate cholera cases and transport them to hospital. It also plans to improve environmental sanitation. Poor sanitation and drainage systems appear to be prime causes of the spread of cholera in Kampala. Poor domestic hygiene, inadequate latrine facilities and open defecation in and along city water courses are also contributing factors.

Fiji: Health Threat in Wake of Floods. (Australian Broadcasting Corporation, 2 February 1999) Health authorities fear an outbreak of disease in Western Fiji as a result of drinking water pollution by overflowing sewage from pit latrines, dead cattle and poor drainage. Record floods were recorded in the wake of Tropical Cyclone Dani which hit the Pacific islands of Fiji and Vanuatu on 19 January 1999. Fijian authorities have mounted an intensive campaign in flood-affected areas and have used chemicals to destroy mosquito breeding sites. ReliefWeb, http://www.reliefweb.int

Abraham, C., Clift, S., & Grabowski, P. Cognitive Predictors Of Adherence To Malaria Prophylaxis Regimens On Return From A Malarious Region: A Prospective Study. SOCIAL SCIENCE & MEDICINE 48 (11): 1641-1654.
    ABSTRACT: Cases of 'imported malaria' into countries where malaria is not endemic are increasing. Evidence suggests that non-use of malaria prophylaxis and lack of adherence are contributing to this increase. Non-adherence may be especially likely because chemoprophylaxis regimens require travelers to continue to take medication for 4 weeks after their return from a malarious region. We investigated the extent to which cognition measures specified by the theory of planned behavior and the health belief model could distinguish between those who reported greater or lesser adherence after their return. Results suggested that malaria prophylaxis adherence could be improved. 22.5% of mefloquine users and 31% of chloroquine and proguanil users reported adherence for 3 weeks or less. A model based on the theory of planned behavior explained approximately 50% of the variance in reported adherence among mefloquine users and 40% among chloroquine and proguanil users. Implications: Targeting key cognitions could enhance adherence on return from malarious regions. Enhancing perceived control over adherence may be important as well as emphasizing susceptibility to malaria infection. Reassuring mefloquine users concerning potential side effects of the drug may also encourage adherence on return.

    ABSTRACT: Objectives. This study sought to define, among sexually transmitted disease (STD) clinic attendees, (1) patterns of sex partner selection, (2) relative risks for gonococcal or chlamydial infection associated with each mixing pattern, and (3) selected links and potential and actual bridge populations. Results. Partnerships discordant in terms of race/ethnicity, age, education, and number of partners were associated with significant risk for gonorrhea and chlamydial infection. In low-prevalence subpopulations, within-subpopulation mixing was associated with chlamydial infection, and direct links with high-prevalence subpopulations were associated with gonorrhea. Conclusions. Mixing patterns influence the risk of specific infections, and they should be included in risk assessments for individuals and in the design of screening, health education, and partner notification strategies for populations.

    ABSTRACT: In response to a letter to the editor by officials from the State of New York Department of Health, experts from the Centers for  Disease Control and Prevention agree that community-based organizations (CBOs) are important in the prevention and control of sexually transmitted diseases. These groups "have led the way in providing STD and HIV outreach services to disadvantaged  populations that health department programs have traditionally had difficulty reaching," the authors explain. They note the need to establish integrated STD and HIV prevention efforts on the patient level into more communities, adding that it is essential to assess "the feasibility and impact of integrating  STD screening and treatment into HIV prevention services."  Integrating STD and HIV efforts at the assessment and policy  development levels is also beneficial. The researchers assert that for seamless STD and HIV prevention services, clinicians, managed care organizations, CBOs, and STD programs must work  together and establish policies.

    ABSTRACT: Objectives. This study sought to identify groups for targeted vaccination during a community-wide hepatitis A outbreak in 1996. Methods. Residents of the Sioux City, Iowa, metropolitan area reported with hepatitis A between September 1995 and August 1996 were sampled and compared with population-based controls. Results. In comparison with SI controls, the 40 case patients were more likely to inject methamphetamine, to attend emergency rooms more often than other health care facilities, and to have a family member who used the Special Supplemental Nutrition Program for Women, Infants, and Children. Conclusions. Groups at increased risk of hepatitis A can be identified and accessed for vaccination during communitywide outbreaks.

    ABSTRACT: Researchers for the Project RESPECT Study Group report the efficacy of counseling in the prevention of HIV and other sexually transmitted diseases. The researchers compared the effects of two counseling programs at five public STD clinics in the United States between July 1993 and September 1996. Over 5,700 heterosexual, HIV-negative subjects were involved, receiving either enhanced counseling and four interactive theory-based sessions, brief counseling and two interactive risk-reduction sessions, or two brief didactic messages. The researchers found that self-reported consistent condom use increased in both the enhanced and brief counseling groups at three- and six-month follow-up intervals as compared to subjects receiving only the didactic messages. Subjects receiving either enhanced or brief counseling had a 30 percent lower rate of STDs through six-months of follow-up. After one year of follow-up, the subjects in both counseling arms had a 20 percent lower rate of STDs as compared to the subjects in the didactic message arms.  The researchers note that the STD reduction was seen in both men and women and occurred consistently at all five STD clinics studied. The authors conclude that counseling, both brief and enhanced, can reduce the risk of STD infection, with brief, interactive counseling providing benefit even in busy public clinics.

    ABSTRACT: Objectives. The purpose of this study was to measure the effectiveness of resource mothers in reducing adverse consequences of maternal phenylketonuria. Methods. Nineteen pregnancies in the resource mothers group were compared with 64 pregnancies in phenylketonuric women without resource mothers. Weeks to metabolic control and offspring outcome were measured. Results. Mean number of weeks to metabolic control was 8.5 (SE = 2.2) in the resource mothers group, as compared with 16.1 (SE = 1.7) in the comparison group. Infants of women in the resource mothers group had larger birth head circumferences and higher developmental quotients. Conclusions.

Measles Control --- South-East Asia Region, 1990--1997. Morbidity and Mortality Weekly Report 48 (25), July 2, 1999.
    In 1989, the World Health Assembly resolved to reduce measles morbidity and mortality by 90% and 95%, respectively, by 1995, compared with the number of cases during the prevaccine era. In 1990, the World Summit for Children adopted a goal to vaccinate 90% of children against measles by 2000. Although these goals have not been met, progress has been achieved toward global measles control, including in the South-East Asia Region (SEAR) member countries* of the World Health Organization (WHO). By the end of 1997, estimated worldwide measles morbidity and death were reduced by 74% and 85%, respectively, and by 70% and 88%, respectively, in SEAR. In February 1999, representatives of the United Nations Children's Fund (UNICEF), WHO, and CDC met and recommended a regional plan of action for measles control. This report summarizes the progress in measles control in SEAR during 1990-1997 and summarizes the plans for future activities in the region.

Adverse Effects Associated with 17D-Derived Yellow Fever Vaccination---United States, 2001-2002.  Morbidity and Mortality Weekly Reports 51(44), November 8, 2002, pp. 989-993.  http://www.cdc.gov/mmwr/preview/mmwrtml/mm5144a1.htm.  In June 2001, seven cases of yellow fever vaccine-associated viscerotropic disease (YEL-AVD) (previously called multiple organ system failure) in recipients of 17D-derived yellow fever vaccine (YEL) were reported to the Advisory Committee on Immunization Practices (ACIP).  ACIP reviewed the cases, recommended enhanced surveillance for adverse events, and updated the ACIP statement on YEL.  This report summarizes the preliminary surveillance findings, including two new suspected cases of YEL-AVD and four suspected cases of YEL-associated neurotropic disease (YEL-AND) (previously called postvaccinal encephalitis).  Although YEL remains essential for travelers to area in which yellow fever (YF) is endemic, these findings underscore the need for continued enhanced surveillance and timely clinical assessment of YEL-associated disease.


STUDY QUESTIONS, ACTIVITIES, AND EXERCISES

1. Condoms and prevention. Condoms can be effective in the prevention of sexually transmitted diseases, if the are used. What predisposing, enabling, and reinforcing factors contribute to the behavior of condom use?

2. Surveillance and control systems. It is expected that public health departments will improve methods for monitoring and controlling the spread of newly recognized diseases, infections introduced from other nations, and unexpected epidemics. Recommend ways in which modern technology might be used towards this end.

3. Immunizations. Visit a passport office where immunization regulations are issued for travelers to foreign countries. Describe one of these diseases and the possible consequences of not being properly immunized against it.

4. Ethics and communicable diseases. Contact or visit a community clinic where sexually transmitted diseases are diagnosed and treated. What policies have been implemented to protect confidentiality and to notify others (parents, sexual partners, employers)? How is patient education conducted for prevention of infection reoccurrence?

5. Incidence and prevalence. Contact a local health officer in regard to communicable diseases that have occurred in the community during recent years. Using HIV/AIDs, tuberculosis, syphilis (as examples) plot the incidence and prevalence of these diseases over the last 30 years. Plot the differences between incidence and prevalence in the trend lines. Note the different trend line for these diseases. To what can these differences be attributed?

6. Milestones in disease eradication are presented as a boxed issues in this chapter. What role do you think private funding agencies should play in disease eradication? With new antibiotic resistant bacteria making their debut, what role should public health officials take in preventing the development of these new strains?
