3 Facts About Covid Virus
1. What is coronavirus?
– Coronaviruses are a large family of viruses with 4 human viruses causing mild colds in all age groups. The virus looks like it has a crown, hence the name. The family also includes viruses from animals that can infect humans in a process called zoonosis. This form of infection has caused severe pneumonia and death, such as the new virus corona virus (COVID-19). Previously, we have seen similar disease with the Severe Acute Respiratory Virus (SARS) and Middle East Respiratory Syndrome Coronavirus Virus (SARS) viruses. COVID-19 began in the city of Wuhan in the Hubei region of China but there is currently local spread in other countries including South Korea, Iran & Italy. Isolated cases who have been infected abroad have been imported to other countries including Norway and other Nordic countries.
2. How does coronavirus infect?
– The original new coronavirus infection probably came from an animal and infected humans. Now it infects people through sneezing and coughing, but also through contact with virus-contaminated surfaces.
3. What are the symptoms?
– Common symptoms are respiratory symptoms with fever, fatigue, cough and very rapid or laboured breathing. Severe symptoms may include pneumonia, severe acute respiratory syndrome, renal failure and death.
2 Opinions About Covid Virus
1. The director general of the WHO has recently spoken of a narrowing of the window of opportunity to control the current epidemic. The tipping point - after which our ability to prevent a global pandemic ends - seems a lot closer after the past 24 hours

2. I think this virus is probably with us beyond this season, beyond this year, and I think eventually the virus will find a foothold and we'll get community based transmission and you can start to think about it like seasonal flu. The only difference is we don't understand this virus

SARS-CoV-2 is a betacoronavirus whose apparent closest relatives, RaTG13 and RmYN02, are reported to have been collected from bats in 2013 and 2019, respectively, in Yunnan Province, China (1). COVID-19 was first reported in December 2019 more than 1,000 miles away in Wuhan City, Hubei Province, China. Beyond these facts, the “origin story” is missing many key details, including a plausible and suitably detailed recent evolutionary history of the virus, the identity and provenance of its most recent ancestors, and surprisingly, the place, time, and mechanism of transmission of the first human infection. Even though a definitive answer may not be forthcoming, and even though an objective analysis requires addressing some uncomfortable possibilities, it is crucial that we pursue this question. Preventing the next pandemic depends on understanding the origins of this one.
