Experts say the case should be taken into consideration and attention to the management of patients discharged from the hospital.

The new Beijing News Express (reporter Dai Xuan) yesterday (February 7) afternoon, a news that the Sino-Japanese Hospital has a patient who was diagnosed with "new crown pneumonia" only after three negative throat swab tests and through the lower respiratory samples. The reporter verified that the case was true, and experts said that the case should be a cause for reflection and attention to the management of patients discharged from the hospital.

On the afternoon of Feb. 7, a message spread online.

The news said that a feverish pneumonia patient from Wuhan to Beijing was diagnosed with a new coronavirus infection pneumonia on February 5 at the respiratory department of China-Japan Hospital and is now waiting to be transferred to a designated hospital. The patient was admitted to the hospital on January 30 with "severe influenza A" after three negative pharyngeal swabs for new coronavirus nucleic acid tests and a positive nucleic acid test for influenza A. After admission, he was intubated and put on a ventilator, and was found to be positive for neo-coronavirus nucleic acid only through alveolar lavage testing.

It was signed as "Sino-Japanese Hospital New Coronavirus Prevention and Control Leading Group".

A respiratory doctor at a tertiary hospital in Beijing revealed that the hospital had informed its staff of the case internally, which should be true. The reporter verified from the relevant person in charge of the health department, the case does exist.

A doctor from the respiratory department of a tertiary hospital in Beijing told reporters that two pharyngeal swab nucleic acid tests are routinely performed on suspected patients, and if there is one positive test, the diagnosis is confirmed, and if there are two negative tests, the infection can basically be ruled out. All three pharyngeal swabs were negative for nucleic acid testing of the new coronavirus, indicating that the virus is insidious.

"The lesions occur in the lungs, the lower respiratory tract, and sometimes the pathogen is not found in the upper respiratory pharynx." Ding Xinmin, chief physician of the Department of Respiratory Medicine at Beijing's Saitan Hospital, explained that it would also be the case that the case was only confirmed positive by alveolar lavage testing, and it is now difficult to sample the lower respiratory tract specimens in every suspected case, which also poses certain challenges to confirm the diagnosis.

However, he also said that similar cases are only isolated cases and that the general public need not panic, and that personal protection should not be slackened during an outbreak. In addition, more attention should be paid to how discharged patients are judged and managed.
