The claim: MERS is the same as COVID-19
Most pandemics in the 20th and 21st centuries have been caused by either influenza – such as the 1918 Spanish flu or the 2009 swine outbreak – or a coronavirus.
SARS, or severe acute respiratory syndrome, first appeared in southern China in 2002, and MERS, or Middle East respiratory syndrome, turned up in Saudi Arabia in September 2012.
A year and a half after coronavirus entered the common lexicon, many remain confused about the difference between COVID-19 (a particular type of coronavirus) and the broader family of viruses confusion that has spawned an array of misinformation.
Importantly, these conditions are all associated with excessive activation of immune cells in the blood (eg macrophages), and immune-competent cells in the brain (glia). The initial immune response occurs, at least in part, via special receptors on the surface of innate immune cells called Toll-Like Receptors. When TLRs recognise Covid-19 within the body, their cell releases molecular signals called cytokines that make us feel unwell. Cytokine storm, the extreme form of cytokine release, is a feature of the most severe aspects of Covid-19 infection. Repeated TLR stimulation provides a stimulus to chronic medical conditions, including chronic pain and the severity of symptoms is associated with the severity of glial activation within the brain.
