The common cold or the cold is a viral infectious disease of the upper respiratory tract that primarily affects the respiratory mucosa of the nose, throat, sinuses, and larynx. [6] [8] Signs and symptoms may appear in as little as two days after exposure to the virus. [6] These may include coughing, sore throat, runny nose, sneezing, headache ...
The treatment and management of COVID-19 combines both supportive care, which includes treatment to relieve symptoms, fluid therapy, oxygen support as needed, [1] [2] [3] and a growing list of approved medications. Highly effective vaccines have reduced mortality related to SARS-CoV-2; however, for those awaiting vaccination, as well as for the ...
Misinformation on the subject of COVID-19 has been used by politicians, interest groups, and state actors in many countries for political purposes: to avoid responsibility, scapegoat other countries, and avoid criticism of their earlier decisions. Sometimes there is a financial motive as well.
Although the common cold is usually caused by rhinoviruses, in about 15% of cases the cause is a coronavirus. The human coronaviruses HCoV-OC43, HCoV-HKU1, HCoV-229E, and HCoV-NL63 continually circulate in the human population in adults and children worldwide and produce the generally mild symptoms of the common cold.
The first coronavirus (B814) was found in washes from a boy with typical common cold symptoms in 1960 during the study led by virologist David Tyrrell at the Common Cold Unit. After washes were inoculated to volunteers and tested for known viruses none was found. Publication about first human coronavirus was published in The BMJ in 1965.
Serologic studies have shown that by the age of five, virtually all children worldwide have been exposed to the virus. Despite near universal infection during early life, reinfections are common in older children and adults. Human metapneumovirus may cause mild upper respiratory tract infection (the common cold).
Human coronavirus OC43 [1] ( HCoV-OC43) is a member of the species Betacoronavirus 1, which infects humans and cattle. [2] [3] The infecting coronavirus is an enveloped, positive-sense, single-stranded RNA virus that enters its host cell by binding to the N-acetyl-9-O-acetylneuraminic acid receptor. [4] OC43 is one of seven coronaviruses known ...
Favipiravir. Favipiravir, sold under the brand name Avigan among others, [3] is an antiviral medication used to treat influenza in Japan. [4] It is also being studied to treat a number of other viral infections, including SARS-CoV-2. [4] Like the experimental antiviral drugs T-1105 and T-1106, it is a pyrazinecarboxamide derivative.
