Time from last immunity event against infection during Omicron-dominant period in Malaysia
The SARS-CoV-2 Omicron variant (B.1.1.529) and its prominent sublineages continue to be the dominant strains (>98%) circulating globally since February 2022 [1–3]. The spike mutations of Omicron resulted in higher viral transmissibility and capability to escape neutralizing antibodies from vaccinated sera [4]. Immune evasion is evident because a higher number of breakthrough and reinfection cases were observed during the Omicron-dominant period [5,6]. Symptomatic COVID-19 cases increased as studies found moderate booster effectiveness against Omicron infection, whereas the effectiveness against severe outcomes was largely preserved [7,8].Antibody response to the inactivated SARS-CoV-2 vaccine among healthcare workers, Indonesia
Healthcare workers (HCWs) are at risk for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due to increased occupational exposure to SARS-CoV-2 (Nguyen et al., 2020). As well as being beneficial for the HCWs themselves, protecting HCWs from SARS-CoV-2 infection is important to prevent disease transmission in healthcare and community settings (Anonymous, 2020). In addition, protecting HCWs from coronavirus disease 2019 (COVID-19) is crucial for the preservation and protection of national healthcare systems (Anonymous, 2020).Post-vaccination cases of COVID-19 among healthcare workers at Siloam Teaching Hospital, Indonesia
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has rapidly spread worldwide. Indonesia reported its first case of COVID-19 on 2 March 2020, and reached more than 1 million cases by February 2021 (World Health Organization, 2021). Among the countries in south-east Asia, Indonesia has the most active COVID-19 cases (Dong et al., 2020), and the nation’s case fatality rate was higher than the global average (2.7% vs 2.2%) at the end of February 2021 (Kementerian Kesehatan Republik Indonesia, 2021).Preliminary findings of COVID-19 infection in health workers in Somalia: A reason for concern
Somalia has a long history of war, conflicts, violence and political instability; this has resulted in a fragile, fragmented and weak healthcare system. Aid workers have often been targeted for carrying out life-saving humanitarian work. The country’s capacity to prevent, detect and respond to emerging and expanding health threats such as coronavirus disease-19 (COVID-19) has been substantially lowered. The Global Health Security Index in 2019 was 16.6 out of 100, indicating that the country was unprepared to manage such epidemics (Homepage - GHS Index, n.d.Institut Pasteur International Network’s efforts to guide control measures against the coronavirus disease 2019 (COVID-19) epidemic among healthcare workers in Africa
Worldwide, healthcare workers (HCWs) are the most valuable resource during epidemics, but they are also tremendously vulnerable as they work at the front-line (Anonymous, 2020; Chou et al., 2020). While the general population has been advised to stay at home to adhere to social distancing rules, HCWs go to work in hospitals, placing themselves and their family contacts at high risk from coronavirus disease 2019 (COVID-19).
