At the end of 2019, pneumonia caused by novel coronavirus 2019 (nCoV) emerged in Wuhan city, China. Many airline travelers moved between Wuhan and Japan at that time, suggesting that Japan is at high risk of invasion by the virus. Diagnostic systems for 2019-nCoV were developed with urgency. Two nested RT–PCR assays and two real-time RT–PCR assays were adapted to local Japanese conditions. As of 8 February 2020, the assays developed have successfully detected 25 positive cases of infection in Japan.

We report a case of patient in Japan with Coronavirus disease 2019 (COVID-19) with false-negative of reverse transcription polymerase chain reaction for Severe Acute Respiratory Syndrome Coronavirus 2 of pharyngeal swab, from a Chinese traveller returning from Wuhan, Hubei Province, China. If a patient is clinically or epidemiologically suspected of COVID-19, appropriate infection and prevention control measures such as standard, contact, and droplet precaution are needed until the patient is proven to be true-negative.

We report the pathological and virological findings of the first autopsy case of the 2009 pandemic influenza (A/H1N1pdm) virus infection in Japan. A man aged 33 years with chronic heart failure due to dilated cardiomyopathy, mild diabetes mellitus, atopic dermatitis, bronchial asthma, and obesity died of respiratory failure and multiple organ dysfunction syndrome. Macroscopic examination showed severe plumonary edema and microscopically the lung sections showed very early exudative-stage diffuse alveolar damage (DAD). Immunohistochemistry revealed proliferation of the influenza (A/H1N1pdm) virus in alveolar epithelial cells, some of which expressed SAα2-3Gal on the cell surface. Influenza (A/H1N1pdm) virus genomic RNA and mRNA were also detected in alveolar epithelial cells. Real-time PCR revealed 723 copies/cell in the left lower lung section from which the influenza (A/H1N1pdm) virus was isolated. Electron microscopic analysis revealed filamentous viral particles in the lung tissue. The concentrations of various cytokines/chemokines in the serum and the autopsied lung tissue were measured. IL-2R, IL-6, IL-8, IL-10, IFN-α, MCP-1, and MIG levels were elevated in both. These findings indicated a case of viral pneumonia caused by influenza (A/H1N1pdm) virus infection, showing characteristic pathological findings of the early stage of DAD.

We herein report a case of severe fever with thrombocytopenia syndrome (SFTS) with Pasteurella multilocida bacteremia in a 65-year-old man with alcoholic cirrhosis who was admitted to our hospital with anorexia and severe fatigue. Laboratory tests revealed pancytopenia and liver and kidney dysfunction. After admission, he developed impaired consciousness, mucosal hemorrhaging, and septic shock. SFTS virus was detected on polymerase chain reaction testing of blood and throat swabs, and Pasteurella multocida was detected on blood culture. Despite being treated with invasive mechanical ventilation, vasopressors, and antibiotics, the patient's condition progressively deteriorated, and he died four days after admission.
