We report the case of a patient with pneumonia caused by the new coronavirus (COVID-19 pneumonia), who contracted the novel coronavirus (SARS-CoV-2) infection on a large cruise ship, and was hospitalized due to fever and cough The fever resolved immediately after admission, however, a mild cough persisted Chest CT showed multiple ground-glass opacities in the upper and lower lobes of both lungs However, we judged that the patient was at a low risk of exacerbation of the disease as he was young, and did not administer any antiviral drugs Since the subjective symptoms improved, we repeated the SARS-CoV-2 PCR test on day 9 after the onset of the illness, but the result was still positive As the patient was observed to have sinus stenosis in the left nasal cavity at the time of collection of the nasopharyngeal swab for testing, sinus CT was performed The findings were suggestive of inflammation of the left nasal mucosa, ethmoid sinusitis, and maxillary sinusitis It took a long 41 days before we could finally confirm two consecutive negative results of the nasopharyngeal swab PCR test for the novel virus It has not yet been clarified whether the SARS-CoV2-19 virus can cause rhinitis and/or sinusitis, but from our experience of this case, we believe that SARS-CoV2-19 can colonize already infected nasal mucosa and sinuses for a prolonged period of time It is necessary to pay attention to this aspect, as it may prolong the disease duration and/or increase the risk of relapse

The patient was a 56-year-old man who presented with a 14-day history of fever, and had been diagnosed by a physician as having pneumonia on the basis of the findings of chest CT He had not travelled abroad and gave no history of close contact with any patients with suspected or confirmed COVID-19 His chest CT showed bilateral multiple ground-glass opacities, distributed predominantly in the peripheral lung regions We suspected COVID-19 pneumonia based on the chest CT findings A nasopharyngeal swab PCR test (PCR) for SARS-CoV-2 on day 1 returned a negative result The following day, a nasopharyngeal swab and a sputum specimen were submitted for repeat PCR testing, and both yielded positive results, confirming the diagnosis of COVID-19 pneumonia in the patient

This is a case report of a male patient in his 50s who developed pneumonia while he was admitted at another hospital The patient received antibacterial drugs, but showed no improvement He was referred to our hospital for further investigation and treatment of pneumonia We made the diagnosis of COVID-19 promptly, based on the clinical history, laboratory results, and chest CT findings This case highlights the importance of carefully observing the patient's clinical course and performing appropriate examinations to make a prompt diagnosis of COVID-19

An immunochromatographic assay that has been developed for the detection of antibodies in blood-derived specimens is raising expectations for the diagnosis of COVID-19, the disease caused by the novel corona virus SARS-CoV-2 Herein, we studied the interval from symptom onset to the first positive results of the immunochromatographic assay for IgM and IgG antibodies in 52 patients with a definitive diagnosis of COVID-19 (disease confirmed by the PCR test) Furthermore, we also examined the test results in 35 patients with acute fever and pneumonia who were negative by the PCR test All patients with a definitive diagnosis of COVID-19 were confirmed to be antibody-positive The mean time from symptom onset to the first positive result for IgM antibody was 11 9 days (minimum: 5, median: 11), and that to the first positive result for IgG antibody was 11 2 days (minimum: 5, median: 11) No significant difference was observed between the tests for IgM and IgG antibodies in terms of the percentage of positive patients or the interval from first onset to the first positive test result There were no patients in whom the test for IgM became positive before the test for IgG In 45 patients (87%), both IgM and IgG became positive at the same time, and in the remaining 7 patients (13%), the test for IgG became positive before that for IgM Of 35 patients with acute fever and pneumonia who tested negative by the PCR test for SARS-CoV-2, not COVID-19, 6 (17 1%) and 1 (2 8%) showed positive results for anti-IgG antibody and anti-IgM antibody, respectively Our study results were quite limited, and we do not intend to conduct a performance evaluation of the reagents contained in the detection kits Assessment of antibody detection reagents for the immunochromatographic assay, which can be used as a complementary test to PCR, is expected in the future;however, the findings should be reviewed carefully
