Interleukin-6 affects the severity of olfactory disorder: a cross-sectional survey of 148 patients who recovered from Omicron infection using the Sniffin’ Sticks test in Tianjin, China
The worldwide COVID-19 pandemic has continued for approximately 3 years, imposing severe burdens on global healthcare systems and economic stability. The main symptoms of COVID-19 are fever and cough (Guan et al., 2020). In addition, an increasing number of studies have found that olfactory disorder (OD), which includes anosmia and hyposmia, is one of the most common clinical symptoms of COVID-19 and may be the first or only symptom in a patient (Eliezer et al., 2020; Heidari et al., 2020). OD occurs in 33-80% of patients with COVID-19 (Mao et al.Epidemiological assessment of SARS-CoV-2 reinfection
COVID-19 began as an outbreak in Wuhan, China, in December 2019 and was declared a pandemic by the World Health Organization (WHO) in March 2020 (WHO, 2020). The disease, caused by SARS-CoV-2, has affected >271,900,000 people worldwide and led to >5,000,000 deaths as of December 19, 2021 (WHO, 2021c). There are currently five SARS-CoV-2 variants that are classified as variants of concern: Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), Delta (B.1.617.2), and more recently, Omicron (B.1.1.529) (WHO, 2021b).SARS-CoV-2 Reinfection Rate and Outcomes in Saudi Arabia: A National Retrospective Study
The emergence of SARS-CoV-2, a virus that causes COVID-19, has infected over 430 million people worldwide (743,205 in Saudi Arabia) and resulted in over 6 million deaths (8993 in Saudi Arabia) as of February 25, 2022. Despite implementing stringent control measures and travel restrictions, COVID-19 continues to circulate globally, and more recently, the resurgence of COVID-19 cases has been observed after the relaxation of lockdown and social distancing procedures as well as the emergence of variants that posed an increased risk to global public health (Tillett et al., 2021).Monitoring the COVID-19 immune landscape in Japan
Since the COVID-19 epidemic spread on a global scale in 2020, it considerably altered daily life. With the hope of mitigating the COVID-19 risk, vaccination campaigns began in December 2020 in many countries, often using a prioritization vaccination strategy (Haas et al., 2021; Hall et al., 2021; Jentsch et al., 2021; Mathieu et al., 2021; Sasanami et al., 2022; Thompson et al., 2021). Mass vaccination campaigns occurred primarily when the original (wild-type) strain, the Alpha variant (B.1.1.7), the Beta variant (B.1.351), or other variants were dominant in circulation and against which the available vaccines provided substantial protection (Chemaitelly et al., 2021; Chung et al., 2021; Dagan et al., 2021; Haas et al., 2021; Hall et al., 2021; Pritchard et al., 2021).Public acceptability of COVID-19 control measures in Singapore, Hong Kong, and Malaysia: A cross-sectional survey
Our findings highlight the importance of sociopolitical context in public perception of public health measures and emphasize the need to continually monitor public attitudes toward such measures to inform implementation and communication strategies.Incidence of SARS-CoV-2 infection among previously infected or vaccinated employees
Prior reports have found lower rates of SARS-CoV-2 infections among those vaccinated against SARS-CoV-2 or with a prior SARS-CoV-2 infection (Dagan et al., 2021; Qureshi et al., 2021). Although an association between vaccination and reduction of SARS-CoV-2 incidence has been well described, it remains unclear how the incidence among individuals with a previous infection compares to vaccinated individuals.SARS-CoV-2 transmission in opposition-controlled Northwest Syria: modeling pandemic responses during political conflict
Ten years into Syria's protracted and violent conflict, more than half of the 22 million prewar population has been displaced and more than half a million civilians have been killed, including more than 900 health workers (UNOCHA, 2020; Fouad et al., 2017). The conflict has decimated the health system, water and sanitation infrastructure, and public health infrastructure crucial for managing infectious diseases. Northwest Syria (NWS), a 2,460 square-kilometer territory bordered by Turkiye on one side and government-controlled areas on the other, has an estimated population of 4.2 million.Critical timing and extent of public health interventions to control outbreaks dominated by SARS-CoV-2 variants in Australia: a mathematical modelling study
The coronavirus disease 2019 (COVID-19) pandemic continues to cause a catastrophic health and economic crisis around the world (McKee and Stuckler, 2020; World Health Organization, 2021). To prevent the consequences of the COVID-19 epidemic, 22 vaccine candidates have been approved by the World Health Organization (Craven, 2021). Yet, achieving global herd immunity with these vaccines will take time, given the existing disparity in COVID-19 vaccination across the globe (Forman et al., 2021). Non-pharmaceutical interventions remain the most effective means for COVID-19 control until herd immunity can be achieved.Comparison of an inactivated Covid19 vaccine-induced antibody response with concurrent natural Covid19 infection
The devastating effect of SARS-CoV-2 is still ongoing around the globe (WHO, 2019). Virus-infected patients are either asymptomatic or have the disease, with clinical course ranging from mild to severe (Yang et al. 2020). HCWs have a higher risk of encountering SARS-CoV-2. The higher risk comes from likely contact with patients carrying high viral loads and virus-infected stuff in the hospitals. Infection rates rise up to 14% in symptomatic and 7.1% in asymptomatic HCWs. These rates are higher than the general population reported so far and suggest an occupational risk (Shields et al. 2020).
