The highest peak occurred on April 23, after the announcement that the number of cases had reached 4,000 and that a vaccine would not be available anytime soon. In the days after the peak, coverage remained quite high, in association with the definition of SARS as a "global threat" by WHO and the twofold increase in the number of probable cases in Italy. The high press coverage was followed by an overall decrease, although small peaks occurred in association with the conflicts among European Ministries on airport measures, increased quarantine measures in China, and the identification of the civet cat as a probable source of SARS-CoV. Coverage tended to be greater on weekends, probably because political stories constitute less competition for space on these days. Evidently, the daily newspaper coverage of SARS has been quite extensive in Italy, especially in the aftermath of WHO alerts and statements by the Ministry of Health regarding new cases and more stringent control measures. During outbreaks of infections, both the media and the public are often criticized for overreacting, yet public concern over serious health hazards is essential in guiding prevention activities (3-5) and in deciding whether to adopt measures that could place restrictions on civil rights, such as quarantine (6) quality of risk-communication of the journalists or of the experts quoted in the articles, wide press coverage of the WHO global alert may have contributed to public-health bodies' taking action towards containing the epidemic. To the Editor: A global outbreak of severe acute respiratory syndrome (SARS) was reported in March 2003 (1) . Most reported cases were in adults. Hong Kong, however, reported 10 pediatric cases (2) with less aggressive clinical courses. The disease became endemic in Taiwan by the end of April 2003 (3). Hualien City, a geographically secluded city in eastern Taiwan, had nine pediatric cases, all mild. The cases occurred in Tzu-Chi High School, a private boarding school for 830 students 12 to 18 years of age, all of whom live in the same building and eat daily meals together in the school cafeteria. On April 28, when a student (case-patient 1) visited the school nurse on the first day that he had a fever, an infection specialist from affiliated Tzu-Chi Medical Center immediately responded. The specialist discovered that this student's close friend in the same class (case-patient 2) was already febrile. Case-patient 2, a Hong Kong resident who leaves Taiwan for Hong Kong every 3 months, had visited Hong Kong twice in March and April 2003. Both students were isolated in the hospital on April 28. Tzu-Chi Medical Center began a search for other febrile students. On April 29, seven more schoolmates were found to have fever >38°C. All were identified on their first day of becoming febrile and were immediately isolated in the hospital. All nine schoolmates underwent chest x-ray examinations and were tested for SARS-associated coronavirus (SARS -CoV) by reverse transcription-polymerase chain reaction (RT-PCR) (4) and DNA sequencing. The tested length for SARS-CoV was 340 bp in the RNA-dependent polymerase region. Those teenagers with diarrhea were tested for Norovirus in their stool by RT-PCR. For those teenagers with cough, throat swabs were cultured for influenza and parainfluenza virus. To reduce the risk for false-positive PCR results, we followed measures to avoid contamination during specimen handling and processing. Two primer sets were used for RT-PCR according to Ksiazek (4) and Drosten (5). The targets are located in the RNA-dependent RNA polymerase gene at different regions, which are separated by approximately 3,000 bp. The laboratory used in RT-PCR analysis is not involved in viral culture or extraction preparation and is located far away from the laboratory for RNA extraction to avoid contamination. Negative-control cDNA was included in each analysis and confirmed that no contamination had occurred. Two operators manipulated RT-PCR analysis for two specimens from the same sample. The specimens were analyzed in different rooms with independent reagents for assurance. Realtime RT-PCR instead of nested RT-PCR was used. Six schoolmates were positive for SARS-CoV by RT-PCR, confirmed later by DNA sequencing for replicase. The tested DNA sequence was >99% identical with a published SARS-CoV sequence. Norovirus was identified in one teenager's stool by RT-PCR; this virus belonged to genogroup I by testing partial cDNA sequence for capsid protein. The tested length was 555 bp, and the virus was 96% identical to strain KU4aGI. Culture of a throat swab for influenza and parainfluenza virus did not grow any virus. The initial signs and symptoms of the nine teenagers were self-reported fever (9/9, range 37.8°C-39.4°C), cough (4/9), general malaise (4/9), diarrhea (4/9), rhinorrhea (3/9), headache (2/9), chills (2/9), sore throat (2/9), and myalgia (1/9).
