I went to Twitter, searched for #coronavirus tweets, and found this useful item provided by Jordan Medics: HUMAN CORONAVIRUS PATHOGEN SAFETY DATA SHEET. It doesn't deal with today's reports out of Saudi Arabia, but it's useful background. Excerpt:
PATHOGENICITY/TOXICITY: HCoV-229E and HCoV-OC43 cause the common cold, a self-limiting upper respiratory tract infection. Infection can lead to a number of illnesses such as bronchitis, gastroenteritis, progressive demyelinating encephalitis, diarrhea, peritonitis, nasal obstruction, rhinorrhea, sneezing, sore throat and cough (1, 5).
They can cause more severe lower respiratory tract infection, including pneumonia in infants, elderly and immunocompromised individuals (1-3).
HCoV-229E is a common agent if coryza, whereas HCoV-OC43 is generally characterized by sore throats (3). HCoV-NL63 causes laryngotracheitis (croup) and nonfatal upper and lower respiratory tract infections in children, elderly, and immunocompromised individuals (1, 3).
HCoV-HKU1 causes mild upper respiratory diseases, the common cold, bronchiolitis, and pneumonia, with symptoms such as rhinorrhoea, fever, cough, febrile seizure, and wheezing (3, 6).
More severe illness may occur in children, adults with underlying disease, the elderly, and may be associated with gastrointestinal illness (1).
