Background Community health workers (CHWs) involved in the COVID-19 response might be at increased risk of developing depression, though evidence is scarce. We investigated effects of COVID-19-related work on changes in depression levels among CHWs in Vietnam and identified sub-groups among CHWs who are at particular risk of developing severe depression. Methods We conducted a cross-sectional online survey among 979 CHWs who were involved in the COVID-19 response in Vietnam, in particular during the 2021 Tet holiday outbreak between January and March 2021. Respondents were asked to report depression symptoms at two-time points, before the start of the COVID-19 pandemic (average June to December 2019) and during the 2021 Tet holiday outbreak using the PHQ-9 mental health questionnaire. We estimated depression levels at both time points and developed univariate and multivariable logistic regression models to estimate odds ratios and 95% confidence intervals (95% CIs) to explore the association between deterioration to high depression levels and selected risk factors. Results Median depression levels among CHWs in Vietnam doubled from 3 (IQR = 2–7) before COVID-19 to 6 (IQR = 3–9) on the PHQ-9 scale during the Tet holiday outbreak. The proportion with normal/minimal levels decreased from 77.1% (95% CI = 74.4–79.7) to 50.9% (95% CI = 47.7–54) (p-value < 0.001), while the proportion of CHWs with moderate, moderately severe, and severe depression levels increased 4.3, 4.5, and five-fold, respectively. Less sleep and poor sleep quality, working in unfavorable work environments, and being involved in contact tracing and the organization of quarantine for suspected cases were associated with an increased risk of deterioration to high depression levels. Conclusions We found a substantial increase in overall depression levels among CHWs in Vietnam due to their COVID-19 related work and a particularly worrisome rise in CHWs suffering from severe depression. CHWs are an indispensable yet often overlooked cadre of work in many low- and middle-income countries and shoulder a heavy psychological burden during the COVID-19 pandemic. Targeted psychological support for CHWs is needed to improve their mental health and to ensure the sustainability of community-based health interventions during COVID-19 and future epidemics.

SARS-CoV-2 variant B.1.1.7, first detected in September 2020 in the United Kingdom of Great Britain and Northern Ireland, has spread quickly to many countries around the world. While some publications have described the clinical features of adult patients with the B.1.1.7 variant, little information is available on newborn patients. We report the clinical characteristics, treatment and care practices for a 21-day-old newborn patient who was confirmed to be infected with SARS-CoV-2 variant B.1.1.7 in Viet Nam during contact tracing after her father was confirmed to be infected with SARS-CoV-2. The patient displayed no symptoms of COVID-19 on admission but 3 days later developed diarrhoea, vomiting, a runny nose and a productive cough. These symptoms lasted for 3 days before becoming milder for 1 day and then stopping until discharge. During treatment, the patient received Vietnamese traditional herbal peppermint extracts for cough and digestive probiotics for diarrhoeal symptoms. A saltwater solution (Sterimar 0.9%) was used to clean the patient’s sinuses. The patient was cared for and fed breastmilk by her mother, who was provided with personal protective equipment, including sterilized infant equipment, medical masks and hand sanitizer, during hospitalization. The patient’s mother tested negative for SARS-CoV-2 throughout hospitalization. In conclusion, we found no severely abnormal clinical symptoms in a newborn infected with SARS-CoV-2 variant B.1.1.7 during treatment. Our case suggests that newborn patients with the B.1.1.7 variant can receive exclusive breastmilk feeding if sufficient preventive measures are provided for both mother and child.
