The COVID-19 pandemic in Bhutan was a part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
The virus was confirmed to have reached Bhutan on 6 March 2020, when a 76-year-old American tourist who had travelled from India tested positive for COVID-19.
The King of Bhutan addressed the nation on 22 March 2020, telling citizens "As a small country with a small population, we can overcome any challenge we are faced with, if the people and the government work together."
The country subsequently implemented strict containment measures, and was able to largely stamp out the outbreak. Bhutan currently has the lowest case fatality rate for COVID-19 at 0.05%, which is significantly lower than the WHO's global case fatality rate of 4.34%, and lower than SARS of 2003. However, the transmission has been significantly greater.
Background
On 12 January 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan City, Hubei Province, China, which was reported to the WHO on 31 December 2019.
The first case of COVID-19 in Bhutan: the case report
In Bhutan, the index case was a 76-year-old American man who had entered Bhutan as a tourist via India. During his first two days in Bhutan, he sought the medical attention for a minor illness of which the symptoms included bloating, loss of appetite, diarrhea, and fatigue. On his fourth day in Bhutan, he was diagnosed as a case of COVID-19 and was admitted at the Jigme Dorji Wangchuk National Referral hospital. Initial chest X-ray revealed mild bilateral patchy infiltrates, and he was started on oseltamivir, ceftriaxone, and doxycycline, and was kept in respiratory isolation on supplemental oxygen.
Over the days of hospitalization, the patient's oxygen requirement gradually worsened; his white blood cell (WBC) count and C-reactive protein (CRP) continued to increase. Point-of-care ultrasound revealed worsening B lines. Then the patient was put on lopinavir and ritonavir and the antibiotics were switched to meropenem and vancomycin. However, he continued to maintain a low-grade fever. Computed tomography of the chest revealed diffuse ground-glass opacities consistent with acute respiratory distress syndrome (ARDS). On the fifth day after diagnosis, the patient had to be intubated and was placed on a ventilator for respiratory support.
He also received a three-day course of 0.5 g/kg (40 g daily) of intravenous immunoglobulin (IVIG) and underwent prone positioning for ARDS. By the next morning, his oxygenation status improved, and 48 hours after the first dose of IVIG, the patient's WBC count and CRP had decreased. The patient was evacuated to his home country after eight days of treatment and significant clinical improvement in Bhutan. His recovery went well, and was extubated seven days after evacuation. Fifteen days after his diagnosis, he no longer required oxygen therapy and rehabilitative therapy was initiated.

May 2020
1 May: The Foreign Minister reported that a 36-year old Bhutanese in Abu Dhabi tested positive yesterday. There are now 12 Bhutanese citizen living abroad who are positive, five of whom have recovered.
2 May: Suspected case: it was reported that a businessman in Jomotsangkha in the Samdrup Jongkhar district of South Eastern Bhutan had tested positive on 1 May for COVID-19 using a rapid test kit, when a team from the Ministry of Health was conducting random sampling tests there. A further sample was sent to a national testing centres unit at Mongar to confirm the result. The person, who was asymptomatic and had no recent travel history, was placed in quarantine to be moved to an isolation ward in Mongar or Thimphu if the further test result proved positive. Contract tracing of this suspected community transmission case was carried out, and about 1,000 people instructed to stay indoors pending the PCR test results of this case. About 60 other people in the same town were tested as part of high-risk community surveillance. Jomotsangkha, which borders India, is considered a high-risk community as the town currently has no internal road connection with the rest of Bhutan and people normally need to travel via Assam to reach other places in Bhutan.
Later in the day, it was announced that the PCR test results of the suspected case in Jomotsangkha were negative. The Prime Minister, Dr. Lotay Tshering, said the previous rapid test was positive for IgM, which means he could have an active viral infection, but was not shedding the virus at the time of the PCR test. The area continues to be kept under high surveillance, with the suspected case and his primary contacts put under isolation or quarantine for at least seven days. The prime minister said the situation would be reviewed only after a second PCR test revealed the suspected case to be negative once more.
