After the emergence of SARS-CoV-2 in late 2019, transmission expanded globally, and on January 30, 2020, COVID-19 was declared a public health emergency international concern.* Analysis early Wuhan, China outbreak (1), subsequently confirmed by multiple other studies (2,3), found that 80% deaths occurred among persons aged ≥60 years. In anticipation time needed for global vaccine supply to meet all needs, World Health Organization (WHO) published Strategic Advisory Group Experts Immunization...
On 31 December 2019, the Municipal Health Commission of Wuhan, China, reported a cluster atypical pneumonia cases. 5 January 2020, WHO publicly released Disease Outbreak News (DON) report, providing information about cases, implemented response interventions, and WHO’s risk assessment advice on public health social measures. Following 9 additional DON reports 209 daily situation reports, 17 August published first edition COVID-19 Weekly Epidemiological Update (WEU). 1 September 2023, 158th...
WHO works, on a daily basis, with countries globally to detect, prepare for and respond acute public health events. A vital component of response is the dissemination accurate, reliable authoritative information. The Disease Outbreak News (DON) reports are key mechanism through which communicates events public. decision produce DON report taken case-by-case basis after evaluating criteria, subsequent process producing highly standardised ensure robustness have been published since 1996, up...
Listeriosis is an opportunistic bacterial infection caused by Listeria monocytogenes and predominantly affects people who are immunocompromised. Due to its severity the population at risk, prompt clinical diagnosis treatment of listeriosis essential. A major step making a collection appropriate specimen(s) for testing. This study explores factors that may influence time between onset illness specimen in order inform policy develop necessary interventions.Enhanced surveillance data on...
Mechanistic mathematical models are often employed to understand the dynamics of infectious diseases within a population or host. They provide estimates that may not be otherwise available. We have developed within-host model in order how pathophysiology Salmonella Typhi contributes its incubation period. The describes process infection from ingestion onset clinical illness using set ordinary differential equations. was parametrized estimated values human and mouse experimental studies...
Abstract Shiga-toxin producing Escherichia coli (STEC) is a pathogen that can cause bloody diarrhoea and severe complications. Cases occur sporadically but outbreaks are also common. Understanding the incubation period distribution factors influencing it will help in investigation of exposures consequent disease control. We extracted individual patient data for STEC cases associated with known source exposure England Wales. The was derived were described according to outbreak...
Restaurant guides such as the Good Food Guide Top 50 create a hierarchy focussing on taste and sophistication. Safety is not explicitly included. We used restaurant associated outbreaks to assess evidence for safety.All foodborne disease in England reported national database from 2000 2014 were compare restaurants (2015) other registered food businesses using Public Health (PHE) outbreak database.
