The World Health Organization declared JN.1 a "variant of interest" Tuesday — a designation that applies to variants that are driving new cases and have genetic changes that could help them ...
Other symptoms are less common among people with COVID-19. Some people experience gastrointestinal symptoms such as loss of appetite, diarrhea, nausea or vomiting. [1] [65] A June 2020 systematic review reported a 8–12% prevalence of diarrhea, and 3–10% for nausea. [2] Less common symptoms include chills, coughing out blood, diarrhea, and rash.
The symptoms of the FLiRT variants are similar to those caused by JN.1, which include: Sore throat. Cough. Fatigue. Congestion. Runny nose. Headache. Muscle aches. Fever or chills. New loss of ...
Other symptoms are also prevalent, but are reported in fewer articles; these symptoms include sleep disorder (100% of patients) and disorder of attention and concentration (20%). [14] These accumulated problems lead to a general (and quantified) reduction in the quality of life and social functioning (measured with the SF-36 scale). [ 14 ]
People with the same infection may have different symptoms, and their symptoms may change over time. Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum , shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of ...
Human behavior affects the R0 value and hence estimates of R0 differ between different countries, cultures, and social norms. For instance, one study found relatively low R0 (~3.5) in Sweden, Belgium and the Netherlands, while Spain and the US had significantly higher R0 values (5.9 to 6.4, respectively).
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
