The emergence and spread of a novel coronavirus (2019-nCoV) from Wuhan, China, has become a global health concern.1 Since the detection of the coronavirus in late December 2019, several countries have reported sporadic imported cases among travelers returning from China.2 We report one family cluster of 2019-nCoV originating from a Chinese man.

On January 22, 2020, a 65-year-old man with a history of hypertension, type 2 diabetes, coronary heart disease for which a stent had been implanted, and lung cancer was admitted to the emergency department of Cho Ray Hospital, the referral hospital in Ho Chi Minh City, for low-grade fever and fatigue. He had become ill with fever on January 17, a total of 4 days after he and his wife had flown to Hanoi from the Wuchang district in Wuhan, where outbreaks of 2019-nCoV were occurring. He reported that he had not been exposed to a “wet market”(a market where dead and live animals are sold) in Wuhan.

Throat swabs obtained from the patient tested positive for 2019-nCoV on real-time reverse-transcription–polymerase-chain-reaction (RT-PCR) assays.3 On admission to the hospital, the man was isolated and treated empirically with antiviral agents, broad-spectrum antibiotics, and supportive therapies. Chest radiographs obtained on admission showed an infiltrate in the upper lobe of the left lung (Figure 1A). On January 25, he received supplemental oxygen through a nasal cannula at a rate of 5 liters per minute because of increasing dyspnea with hypoxemia. The partial pressure of oxygen was 57.2 mm Hg while he was breathing ambient air, and a progressive infiltrate and consolidation were observed on chest radiographs (Figure 1B through 1D). His fever disappeared on January 25, and his clinical condition has improved since January 26. His wife had no symptoms of illness while they were traveling. She was healthy as of January 28.
