Reliable determinations of non- ortho PCBs in food have been performed by high-resolution MS, as demonstrated in interlaboratory studies. Diphtheria antitoxin was administered; polymerase chain reaction testing of a membrane sample was positive for Corynebacterium diphtheriae toxin genes at CDC. The observed hepatic sequestration is probably due to binding to constitutive rather than induced CYP 1A2 proteins, as, in humans, CYP 1A2 is primarily expressed constitutively and induced in the liver Diliberto et al. TCDD had no effect on the body-weight gain of dams during gestation or on the weight of male pups during the assessment period. The deaths occurred only at the highest dose, four females dying during the 13 weeks of treatment and two males and two females dying between 14 and 49 days during the week post-dosing observation period.

H7 reported by active surveillance through FoodNet did not change substantially, although it decreased in 2. During , a total of 3, cases of E. Healthy cattle, which harbor the organism as part of the bowel flora, are the main animal reservoir for E.
H7 and other Shiga-toxin producing E. The majority of reported outbreaks are caused by contaminated food or water. Reported cases of E. H7 infection have decreased since , following implementation of U. Department of Agriculture measures to reduce contamination of meat through improved processing.
Direct transmission from animals and their environments to humans in settings such as petting zoos and other animal exhibits remains a growing public health concern 3 ,4. During , a total of , cases of gonorrhea were reported 1. Gonorrhea rates were slightly lower than rates during In , for the first time, the reported gonorrhea rate among women Rates among non-Hispanic black women aged years 2, Decreased susceptibility to fluoroquinolone antibiotics has also been reported from certain regions 2.
In , the prevalence of fluoroquinolone-resistant Neisseria gonorrhoeae infections continued to increase, particularly among men who have sex with men MSM. Fluoroquinolones are no longer advised for treatment of gonorrhea in Hawaii or California or for infections among MSM 3. The continued low number of invasive Hib infections among children from an estimated 20, cases annually in the prevaccine era is a result of the successful delivery of highly effective conjugate Hib vaccines to children, beginning at age 2 months 1 ,2.
Because discrepancies in serotyping results have occurred among laboratories, CDC requests that state health departments obtain and send all invasive H. Hemolytic uremic syndrome HUS is a syndrome defined by the triad of hemolytic anemia, thrombocytopenia, and renal insufficiency. The patients reported in national notifiable diseases surveillance include only those with antecedent diarrheal illness.
However, persons infected with E. H7 rarely progress to HUS 1, 2. Hepatitis A vaccine is recommended for persons at increased risk of hepatitis A e.
Since routine childhood vaccination was recommended in , the overall hepatitis A rate has declined steadily, and in , it was the lowest 2. The decline in rates has been greater among children and in states where routine childhood vaccination is recommended, suggesting an effect of childhood vaccination. The dramatic declines in disease rates in the age groups and areas in the United States that have historically accounted for the majority of reported cases have resulted in a shift in the epidemiology of this disease.
Hepatitis A rates, which historically were much higher in the western states, are now similar in all regions of the United States, and an increasing proportion of cases occur among adults, particularly those in populations at high risk e.
Despite declining overall rates, outbreaks continue to occur. In , several foodborne outbreaks were reported, including one in Pennsylvania that accounted for more than cases; the produce implicated in each outbreak was believed to have been contaminated during harvest 3.
The steady decline in hepatitis B rates coincides with the implementation of a national strategy to eliminate hepatitis B virus HBV 1. Among adults, a high proportion of cases occur among persons in identified high-risk populations i. Monitoring acute hepatitis C rates nationally has been challenging because 1 available serologic tests cannot distinguish acute infection from past or chronic infection, and 2 not all health departments have the resources to determine if a positive laboratory report for hepatitis C virus HCV infection represents acute infection.
Consequently, the most reliable estimates of acute hepatitis C incidence have historically come from sentinel surveillance. In recent years, analysis of data on acute, symptomatic hepatitis C collected through the National Notifiable Diseases Surveillance System has yielded results similar to those from sentinel surveillance, indicating that the quality of national surveillance data for acute hepatitis C has improved.
Direct reporting of anti-HCV--positive test results by laboratories has increased the completeness of reporting of HCV-infected persons to health departments. The reporting of other available laboratory or clinical data would improve surveillance for hepatitis C by providing information to identify patients with acute disease. Improving the accuracy of hepatitis C surveillance data continues to be important because monitoring hepatitis C incidence trends provides information needed to evaluate the effectiveness of prevention efforts and identify additional opportunities for prevention.
By December , all 50 states and the District of Columbia had implemented HIV surveillance systems, including both name-based and nonname-based systems. Since , a total of 33 areas 32 states and the U. CDC will assess the implementation and effectiveness of prevention activities through multiple monitoring systems, including use of new performance indicators for state and local health departments and community-based organizations 1.
In the 33 areas 32 states and the U. Listeriosis is a severe but relatively uncommon infection caused by Listeria monocytogenes ; it was made a nationally notifiable disease in Listeriosis is primarily foodborne and occurs most frequently among persons who are older, pregnant, or immunocompromised.
Incidence was highest 1. Molecular subtyping of L. Recent outbreaks have been linked to ready-to-eat meat 1 and unpasteurized cheese 2. In , incidence of listeriosis as reported to FoodNet active surveillance was 0. Department of Agriculture USDA released a national Listeria Action Plan to help guide control efforts by industry, regulators, and public health officials 4. The number of Lyme disease cases reported for Pennsylvania in included 4, confirmed cases and 1, suspected cases. In contrast, the number of suspected Lyme disease cases reported annually for Pennsylvania during ranged from two to 11 cases.
The increase in the number of suspected cases is attributable to changes in reporting practices. Nevertheless, new prevention tools and techniques are becoming available. Recent studies indicate that peridomestic tick exposure can be reduced substantially through simple landscaping changes, and bait boxes that deliver rodent-targeted acaricide are now available through certain pest control operators.
Other products under development include devices for reducing ticks on deer and naturally occurring fungi that kill ticks on vegetation. A total of 56 confirmed measles cases, two of them fatal, were reported during by 15 states. Of the 56 cases, 24 were internationally imported, and 19 resulted from exposure to persons with imported infections. In two other cases, virologic evidence indicated an imported source.
The sources for the remaining 11 cases were classified as unknown because no link to importation was detected. Three outbreaks occurred in size range: The case outbreak was in Hawaii and included persons aged 3 months years; this outbreak began simultaneously with a measles outbreak in the Republic of the Marshall Islands, which resulted in cases and three deaths 3. During , a total of 11, cases of pertussis were reported incidence: This age group had the highest reported incidence Among the other pertussis cases, occurred among children aged months Pertussis continues to cause morbidity in the United States despite high coverage levels for childhood pertussis vaccine.
The incidence of reported pertussis has increased from 2. How much of this increase is caused by increased recognition and better reporting of cases is unclear 1 ,2.
Adolescents and adults can become susceptible to disease when vaccine-induced immunity wanes, approximately years after pertussis vaccination 2. The actual number of pertussis cases especially among adolescents and adults continues to be substantially underreported because the pertussis cough illness resembles other conditions, infected persons might not seek medical care, and availability of reliable diagnostic tests is limited.
Culture for Bordetella pertussis is highly specific but has low sensitivity. Polymerase chain reaction is not standardized, and its use has led to overdiagnosis of pertussis during certain outbreaks 4.
New strategies are needed to reduce the burden of pertussis disease in the United States; pertussis vaccines for adolescents and adults are under review by the Food and Drug Administration. Salmonella isolates are reported by serotype through the Public Health Laboratory Information System. A substantial proportion of S. During , the proportion of multiple drug-resistant strains of S.
On March 12, , the World Health Organization WHO issued a global alert for severe acute respiratory syndrome SARS , a potentially fatal new infectious disease that can spread rapidly from person to person and via international air travel. WHO and its partners, including CDC, initiated a rapid, intensive, and coordinated investigative and control effort that led within 2 weeks to the identification of the etiologic agent, SARS-associated coronavirus SARS-CoV , and to a series of effective containment efforts.
Of the total cases reported from the United States, were classified as suspected; 19 were classified as probable; and eight were laboratory confirmed 2. Prolonged, multistate outbreaks of S. A new serotype of Shigella boydii has been reported in the United States and Canada 4.
CDC estimates that approximately 11, cases of invasive GAS disease and 1, deaths occurred nationally during The incidence of invasive GAS infections in the United States has been relatively stable during the past 5 years range: For the third straight year, the proportion of pneumococcal isolates that were drug resistant declined.
Of the 3, S. Approximately one in eight In February , the Food and Drug Administration licensed a pneumococcal conjugate vaccine for use in infants and young children.
Vaccine use has reduced rates of invasive pneumococcal disease markedly among children, the vaccine's target age group, and among unvaccinated older persons and has also reduced racial disparities in disease risk 4. During , a total of cases of congenital syphilis were reported As with primary and secondary syphilis, the rate of congenital syphilis has declined sharply in recent years, from a peak of The continuing decrease in the rate of congenital syphilis likely reflects the substantial reduction in the rate of primary and secondary syphilis among women.
Congenital syphilis persists in the United States because a substantial number of women do not receive syphilis serologic testing until late in their pregnancies or not at all. This lack of screening is often related to absent or late prenatal care 2. During , a total of 7, primary and secondary syphilis cases were reported, compared with 6, cases in The rate was the lowest since reporting began in The rate 2. This disparity between men and women, observed across all racial and ethnic populations, along with reported outbreaks of syphilis in large urban areas among men who have sex with men MSM , indicates that increases in syphilis are continuing to occur among MSM.
Rates remain disproportionately high in the South and among non-Hispanic blacks, but these rates are continuing to decline 1, 2. In , a total of 20 cases of tetanus were reported from 13 states and the District of Columbia. During , a total of 14, tuberculosis TB cases rate: This decline is the smallest since , when TB incidence peaked after a 7-year resurgence 1.
In addition, the rate remains higher than the national interim objective of 3. In descending order, the highest rates per , population were reported among Asians The TB rate among foreign-born persons has declined since from In , the case rate was 8.
CDC is collaborating with public health partners to implement TB control initiatives for recent international arrivals and residents along the border between the United States and Mexico and to strengthen TB programs in countries with a high incidence of TB disease 2.
CDC has recently updated its comprehensive national action plan to reflect the realignment of its priorities with the Institute of Medicine report 3 and to ensure that priority prevention activities are undertaken with optimal collaboration and coordination among national and international public health partners 4.
A total of cases of tularemia were reported in , compared with an annual average of cases for the preceding 3 years. Noteworthy were cases involving a child who apparently acquired tularemia from exposure to pet hamsters, an outbreak among commercially distributed prairie dogs, an unusual case of intra-abdominal tularemia in a patient with stomach cancer 1 , and a cluster of pneumonic tularemia cases among lawn-care workers who mowed over a dead rabbit. In , a total of cases of typhoid fever were reported in the United States.
Persons visiting friends and relatives in south Asia appear to be at particular risk, even during short visits 1. Salmonella Typhi strains with decreased susceptibility to ciprofloxacin are increasingly common in that region and should be treated with alternative antimicrobial agents 2. Typhi outbreaks in the United States are generally limited in size but can cause substantial morbidity; they are most often foodborne and warrant thorough investigation 3.
A sexually transmitted outbreak of typhoid fever has been recognized and reported 4. Compared with , cases declined The Council of State and Territorial Epidemiologists CSTE recommends that all states establish statewide individual varicella case reporting by 1. The objectives of varicella surveillance at state and national levels are to 1 monitor the epidemiology of varicella by age and place and over time, 2 monitor the impact of widespread and increasing immunization on the epidemiology of varicella, and 3 allow prompt implementation of disease control measures.
In , CSTE recommended that states report varicella deaths to CDC to monitor the impact of routine varicella vaccination on varicella-related mortality 2.
In , two states Arkansas and Maryland each reported one varicella death; ages of persons at time of death were 12 and 18 years.
Reporting of varicella deaths is incomplete, which limits the usefulness of mortality data in assessing the impact of the varicella vaccination program. CDC encourages states to report varicella deaths, so the risk factors for varicella-related mortality can be identified, and the percentage of deaths that would have been directly preventable by following current recommendations for vaccination can be determined. During , for the fifth consecutive year, epidemic and epizootic West Nile virus WNV activity occurred in the United States, including a substantial epidemic of neuroinvasive WNV disease in the Great Plains states, widespread perennial reemergence in areas of previous activity, and continued geographic expansion into western states.
The WNV epidemic in the United States was comparable in size to, but focused further west than, the epidemic, which was centered in states along the Mississippi River Valley 1. Illness onset dates were April December 5; the epidemic peak occurred during the week ending August In , a total of presumptively WNV-viremic blood donors were identified through nationwide blood screening, and investigations were initiated to track birth outcomes among approximately 70 women with WNV illness acquired during pregnancy 2 , 3.
Increased surveillance for human WNV illness cases might have resulted in improved surveillance for other domestic arboviruses of public health importance. In , WNV activity was reported from 2, counties in 46 states and D.
In addition, 12, WNV-infected dead birds were reported from 43 states and D. In , a total of 14 cases of neuroinvasive illness caused by eastern equine encephalitis virus were reported from eight states Alabama, Florida, Georgia, Louisiana, New Jersey, North Carolina, South Carolina, and Virginia , equaling the maximum number reported to CDC in any year during In addition, a large eastern equine encephalitis epizootic among equines cases and including dogs two cases and other veterinary species 18 cases was reported in 19 states.
