Management of COVID-19 in a Deployed Setting.

INTRODUCTION

Hamid Karzai International Airport is a NATO military base connected to the international airport in Kabul, Afghanistan. It is one of the larger NATO installations in Afghanistan, and with its location being one of the main hubs for international transit, the base has been at the frontline since the beginning of the COVID-19 pandemic. Hamid Karzai International Airport base commanders and medical staff have been at the forefront, continually developing policies and procedures to mitigate the pandemic in a deployed setting.

MATERIAL AND METHODS

On base, approximately 4,000 people from 58 different nations lived within 0.5 km2. Diagnosis of COVID-19 was made by the detection of nucleic acid from the SARS-CoV-2 virus in nasopharyngeal/oropharyngeal swabs using real-time polymerase chain reaction (BioFire or GeneXpert). Serological tests (detecting IgM and IgG antibodies) were used as a screening tool. Data were reported from April 1 to September 12, 2020.

RESULTS

Three thousand four hundred and sixty-six PCR tests were run in the reported period. Four hundred and seventy-eight positive cases were identified. Of these, only 106 reported symptoms. Seventy-eight presented spontaneously to the emergency room, while the remaining positive cases were identified as a result of aggressive testing of close contacts, base screening and surge testing. Twenty-two patients required oxygen treatment. One patient required mechanical ventilation and later died after strategic evacuation.

DISCUSSION

Mitigation of COVID-19 was achieved by measures to reduce the spread of the virus, measures to reduce the population, and a medical response plan. To manage the logistic burden of isolating and quarantining a large portion of the population, a multinational and multidisciplinary COVID Task Force was formed.

CONCLUSIONS

In a military population of mostly young and healthy individuals, the majority of COVID-positive patients will have fewer symptoms, and therefore, the aggressive screening of asymptomatic personnel is necessary. Outbreaks of COVID-19 in a military base could have a detrimental impact on missions but may be contained and controlled with quarantine, isolation, and aggressive contact tracing.
