The Christadelphian Sunday School Union (CSSU) is an organisation which provides lessons, books, magazines and other services for Christadelphian Sunday schools and youth groups. [1] [2] The CSSU provides lessons both for the use of teachers, and also for distance education. Materials are divided for ages 3–6, 7–10, 11-14 and 14+.
Middle East respiratory syndrome (MERS) Middle East respiratory syndrome–related coronavirus (MERS‑CoV) 2012 Discovered in Jeddah, Saudi Arabia. [36] Caused outbreaks in 2012, 2015, and 2018. Pigs Enteritis: Porcine coronavirus HKU15 (PorCov‑HKU15) 2014 Discovered in Hong Kong, China. [37] Humans Coronavirus disease 2019 (COVID‑19)
The betacoronaviruses of the greatest clinical importance concerning humans are OC43 and HKU1 (which can cause the common cold) of lineage A, SARS-CoV-1 and SARS-CoV-2 (the causes of SARS and COVID-19 respectively) of lineage B, [2] and MERS-CoV (the cause of MERS) of lineage C. MERS-CoV is the first betacoronavirus belonging to lineage C that ...
The virus MERS-CoV is a member of the beta group of coronavirus, Betacoronavirus, lineage C. MERS-CoV genomes are phylogenetically classified into two clades, clade A and B. The earliest cases were of clade A clusters, while the majority of more recent cases are of the genetically distinct clade B. [ 10 ]
The virus, which causes Middle East respiratory syndrome (MERS), is a novel coronavirus that was first identified in a patient from Jeddah, Saudi Arabia on 6 June 2012. Sporadic cases, small clusters, and large outbreaks have been reported in 24 countries, with over 2,600 cases of the virus and over 900 deaths, as of 2021.
In early and mid-January, the virus spread to other Chinese provinces, helped by the Chinese New Year migration. Wuhan was a transport hub and major rail interchange. [204] On 10 January, the virus' genome was shared publicly. [205] A retrospective study published in March found that 6,174 people had reported symptoms by 20 January. [206]
For example, school closures during the 2014–2016 Ebola outbreak in West Africa increased school dropouts, rates of child labor, violence against children, and teen pregnancies. [ 31 ] The Ofsted report conducted by the UK government stated that some children at every age group had regressed in their skills, but some had thrived.
Virus infections start when viral particles bind to host surface cellular receptors. [158] Protein modeling experiments on the spike protein of the virus soon suggested that SARS‑CoV‑2 has sufficient affinity to the receptor angiotensin converting enzyme 2 (ACE2) on human cells to use them as a mechanism of cell entry .
