RESUMO
Four years after the first case of COVID-19, the world is still determining how best to prevent and control the long-term effects of SARS-CoV-2 infection. Non-pharmaceutical interventions (NPIs) were employed at the start of the pandemic as the only available options, prior to effective vaccines and antiviral agents. The World Health Organization recommended dual vaccination for 70% worldwide as the threshold for a return to "normal" community life. Immunization rates needed to increase in all global regions, irrespective of socioeconomic status, necessitating more equitable access. During the pandemic, wealthier countries hoarded vaccine supplies even when their citizens were immunized. This highlights the already enormous difficulties in healthcare provision faced by low-income sub-Saharan African countries, which remain at risk as industrialized nations have progressed to a post-pandemic era. Thus, in addition to redoubling vaccination efforts public health policymakers should consider ongoing and future use of NPIs. In this narrative account, we advocate that various NPI practices should not be shelved; rather, more research is needed to evaluate their impact in parallel with booster vaccination. This especially applies to so-called "long COVID". Lessons learned from implementing best practices in resource-limited settings should be incorporated into preparedness guidelines for future infectious disease outbreaks.
RESUMO
From regional and rural grassroots to a nationwide level, Vietnam has established a four-tiered hierarchical healthcare system, comprising national, provincial, district, and commune healthcare centers. Over the last three decades, alongside increasing provision of universal health insurance coverage and cutting healthcare expenditure, the country has demonstrated its dedication to preventative medicine and health promotion. Recent investment in research, development, and production has led to "homegrown" vaccines for SARS-CoV-2 now undergoing clinical trial. Nevertheless, despite substantial progress in improving health outcomes for the entire population, the healthcare sector experiences significant challenges. The current public system is paper-based, requires digitalization, and lacks information technology support. In common with many other countries, there is a vast disparity in the distribution of healthcare professionals between cities and rural areas, as well as between private and public sectors. Consequently, public healthcare in remote locations is particularly underserved. Moreover, ongoing underfunding caused by high out-of-pocket expenses for the average salary, as well as stigmatization of sensitive health issues by a largely conservative populace, demand a well-articulated and culturally sensitive approach. As the level of smartphone ownership and internet coverage are both comparatively high for Southeast Asia, the introduction of telemedicine, mobile health applications, and other digital health solutions may be both practicable and beneficial. Importantly, in order to develop healthcare facilities and reduce patient direct payments, the key issue of funding must be addressed. In order to overcome disease-related stigma, a locally tailored program of community education, awareness, and engagement is required. In summary, in several ways, Vietnam provides a role model for developing healthcare systems in low- and middle-income countries. There are undoubted hurdles to overcome, but the country continues to construct a healthcare system that is accessible and affordable for the majority.
