Summary
Tuberculosis (TB) cases in foreign-born individuals increased significantly in the US from 1993-1998. Targeted TB control strategies for foreign-born populations are crucial for TB elimination efforts.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- Immigration significantly sustains tuberculosis (TB) incidence in the United States.
- Understanding TB trends in foreign-born populations is vital for public health initiatives.
Purpose of the Study:
- To analyze trends and characteristics of tuberculosis cases among foreign-born individuals in the US.
- To inform TB program planning and policy development based on foreign-born case data.
Main Methods:
- Descriptive analysis of US tuberculosis surveillance data from 1993 to 1998.
- Examination of demographic and clinical characteristics of foreign-born persons diagnosed with TB.
Main Results:
- Foreign-born TB cases rose by 2.6% (1993-1998), increasing their proportion of total US cases from 29.8% to 41.6%.
- The TB case rate was substantially higher in foreign-born (32.9/100,000) versus US-born (5.8/100,000) individuals.
- Over half of foreign-born cases occurred within 5 years of US arrival; key origin countries included Mexico, Philippines, Vietnam, India, China, Haiti, and South Korea.
Conclusions:
- Reducing the impact of TB in foreign-born populations is essential for achieving US TB elimination goals.
- Tailoring TB control strategies to foreign-born communities and global TB efforts are critical.
- Increased use of directly observed therapy (DOT) showed improved treatment completion rates.

01:08Prevalence and Incidence
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...

01:28Infectious Diseases and Their Occurrence
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
