Access to Information and Health care Services for Vietnamese Migrant Workers Overseas During the COVID-19 Pandemic

The COVID-19 pandemic caused a global mobility deadlock with nearly all international borders closed for non-essential travel, left migrants in countries of destination acutely vulnerable with risks to health, as well as socioeconomic and social security status, compounded by diverging measures and impacts on mobility.

Treatment for COVID-19 patients in Vietnam: Analysis of time-to-recovery

To describe the recovery time and related factors among COVID-19 patients in Vietnam. Methods: We used the secondary data obtained from the official database of the Ministry of Health of Vietnam and other public data sources that were available by April 9th, 2020. Cox proportional hazards model was carried out to identify factors related to recovery time among COVID-19 patients. Results: By April 9th, 2020, the cumulative number of COVID-19 cases detected in Vietnam was 255, of which 129 (50.6%) patients had fully recovered. The median recovery time of patients was 17 (95% CI=16-19) days.

The natural history and transmission potential of asymptomatic severe acute respiratory syndrome Coronavirus 2 infection

Background. Little is known about the natural history of asymptomatic severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection. Methods. We conducted a prospective study at a quarantine center for coronavirus disease 2019 in Ho Chi Minh City, Vietnam. We enrolled quarantined people with reverse-transcription polymerase chain reaction (RT-PCR)–confirmed SARS-CoV-2 infection, collecting clinical data, travel and contact history, and saliva at enrollment and daily nasopharyngeal/throat swabs (NTSs) for RT-PCR testing.

The effects of border shutdowns on the spread of COVID-19

Objectives: At the beginning of the coronavirus disease 2019 (COVID-19) pandemic, some countries imposed entry bans against Chinese visitors. We sought to identify the effects of border shutdowns on the spread of the COVID-19 outbreak. Methods: We used the synthetic control method to measure the effects of entry bans against Chinese visitors on the cumulative number of confirmed cases using World Health Organization situation reports as the data source. The synthetic control method constructs a synthetic country that did not shut down its borders, but is similar in all other aspects.

Transmission of SARS-CoV 2 During Long-Haul Flight

To assess the role of in-flight transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we investigated a cluster of cases among passengers on a 10-hour commercial flight. Affected persons were passengers, crew, and their close contacts. We traced 217 passengers and crew to their final destinations and interviewed, tested, and quarantined them. Among the 16 persons in whom SARS-CoV-2 infection was detected, 12 (75%) were passengers seated in business class along with the only symptomatic person (attack rate 62%).
