BACKGROUNDThere remains a need for asthma surveillance in Miami-Dade County toestablish its incidence and prevalence,better document asthma morbidity,determine the impact of ongoing interventions, identify areas in the community where prevention may be needed,educate the community, improvemedical practices in physicians officesand hospitals, design prevention programs, and develop resources thatmay not be currently available forasthma and its associated health problems.The limited prevalence data availableindicate that asthma is a relatively2.

describe demographic and risk factors,medication, health care utilization patterns,etc. in patients diagnosed with asthma, anddisseminate results to health care providers and the community.3. STUDY POPULATION Patients presenting history or symptoms ofasthma:WheezingChronic cough for at least 3 weeks.Nocturnal awakening with dyspnea,cough, wheezing. Southern Miami-Dade County. 2-64 years old; not institutionalized population.The study is being currently conducted at twoEmergency Rooms (Baptist Hospital and MiamiChildren's Hospital) and several sentinel outpatient clinics (Helen B. Bentley Community Clinic,Community Health Initiative (CHI) clinics, Pediatric Associates of Homestead, Miami Children'sMobile Clinic, Asthma Center, and Pediatric Pulmonary Center).4. OUTLINE OF THE SYSTEMhistory and utilization of health care services.The collected information regarding asthmawill be expanded with additional informationdata from abstracted medical records. Validation of case definition: pulmonologistwill review pulmonary function tests (PFT) results, questionaries data and abstracted medicalrecords data on a sample of incident case. Analysis of data: evaluate the project and disseminate results.5. DATA ANALYSISWe will determine: Incidence and prevalence rate estimates. Wewill estimate incidence and prevalence rates foradult and pediatric asthma in SouthMiami-Dade County based on all cases thatmeet the incident and prevalent asthma casedefinitions. Sample size estimate. We will calculate thesample size needed in an ongoing surveillancesystem to accurately calculate the incidence/prevalence of asthma in southern Miami-DadeCounty. Epidemiologic description. Data gatheredthrough the questionnaires and medical recordreview will be analyzed regardingdemographics, severity of disease, health careuse, asthma management and risk factors. Identification of patients: Patients with symptoms suggestive of asthma are identified atemergency departments and outpatient sites. Enrollment of candidates: Patients who want Validity of case defintion.to participate sign informed consents and complete screening questionnaire. It is a voluntarysystem. Participating patients receive healtheducation information by phone and mail. Description of asthma surveillance process:staff for asthma project will interview patientsby phone using surveillance questionnairewhich includes issues on symptomatology, severity, risk factors, medication, familyVolume 4.

progress to the respiratory phase.Treatment regimens have included severalantibiotics to presumptively treat known bacterialagents of atypical pneumonia. In several locations,therapy also has included antiviral agents such asoseltamivir or ribavirin. Steroids have also been administered orally or intravenously to patients incombination with ribavirin and other antimicrobials.At present, the most efficacious treatment regimen,if any, is unknown.In the United States, clinicians who suspect cases ofSARS are requested to report such cases to theirstate health departments. CDC requests that reportsof suspected cases from state health departments, international airlines, cruise ships, or cargo carriers bedirected to the SARS Investigative Team at the CDCEmergency Operations Center, telephone770-488-7100. Outside the United States, clinicianswho suspect cases of SARS are requested to reportsuch cases to their local public health authorities.Additional information about SARS (e.g., infectioncontrol guidance and procedures for reporting suspected cases) is available at http://www.cdc.gov/ncidod/sars.

As ofMarch 26, CDC has received 51 reports of suspected SARS cases from21 states (Table), identifiedusing the CDC updated interim case definition (Box).The first suspected casewas identified on March15, in a man aged 53 years who traveled to Singapore and became ill on March 10. Four clusters ofsuspected cases have been identified, three of whichinvolved a traveler who had visited Southeast Asia(including Guangdong province, Hong Kong, orVietnam) and a single family contact. One of theseclusters involved suspected cases in patients L andM who had stayed together at hotel M during March1-6, when other hotel guests were symptomatic. Patient L became sick on March 13 after returning tothe United States. His wife, patient M, became illseveral days after the onset of her husband's symptoms, suggesting secondary transmission. Three patients in the United States with suspected SARS(patients I, L, and M) reported staying at hotel Mwhen other persons staying in the hotel were symptomatic. The fourth cluster began with a suspectedcase in a person who traveled in Guangdong province and Hong Kong. Two HCWs subsequently became ill at the U.S. hospital where this patient wasadmitted.Volume 4. Issue 3March 2003Page-5

Laboratory investigations. On March 24,CDC announced that laboratory analysis hadidentified a previously unrecognized coronavirus in patients with suspected or probableSARS. The new coronavirus was isolated inVero E6 cells from clinical specimens of twopatients in Thailand and with suspected SARS.The isolate was identified initially as a coronavirusby electron microscopy (EM) (Figure 3).The identity was corroborated by results of immunostaining, indirect immunofluorescence antibody (IFA) assays, and reverse transcriptasepolymerase chain reaction (RT-PCR) with sequencing of a segment of the polymerase gene.IFA testing of sera and RT-PCR analysis ofclinical specimens from six other SARS caseswere positive for the new coronavirus. Coronavirus particles also were identified by EM incells obtained by bronchial lavage from a patientwith SARS. Sequence analysis suggests thatthis new agent is distinct from other knowncoronaviruses. Other laboratories collaboratingin the WHO-led investigation have found similar results and also have isolated a different virus, human metapneumovirus, from some patients with suspected SARS. Information is insufficient to determine what roles these two viruses might play in the etiology of SARS.Reported by:T Tsang, T Lai-Yin, L Pak-Yin, M Lee, Dept ofHealth, Hong Kong.
