A young coronavirus is spreading around the world , having do nearly 100,000 sickness and thousands of deaths globally . Here are answer to some basic questions about the new coronavirus .
What is the new coronavirus?
Coronaviruses name a big family of viruses that can cause respiratory illnesses such as the unwashed cold . The new computer virus is a character of coronavirus that had never been see before . It first appear in Wuhan , China , in December 2019 . functionary have named the new virus SARS - CoV-2 , due to its genetic similarity to the coronavirus that causes severe acute respiratory syndrome , or SARS . The official name for the disease due to SARS - CoV-2 is COVID-19 .
What are the symptoms?
cover symptom in patients have vary from mild to severe and can include feverishness , coughing and shortness of intimation , according to the CDC . Read symptom .
How long does it take for symptoms to show up?
The time between catching a virus and showing symptom of the disease is known as the brooding period . For the new coronavirus , the inucbation period is estimate to be between one day and 14 day , although some studies have report an brooding full stop as long as 24 daytime . show more about theincubation flow for the new coronavirus .
How does the coronavirus spread?
The computer virus is recollect to unfold principally through respiratory droplets produced when an septic person coughs or sneezes . But other transmission path are possible . Read more about thespread of the new coronavirus .
How deadly is the virus?
The human death rate of the new coronavirus is still being studied , but it seems to be deadly than the flu , which has a fatality charge per unit of about 0.1 % . In a large study issue Feb. 18 in the China CDC Weekly , researchers found a end rate from COVID-19 to be around 2.3 % in mainland China . But on March 5 , the World Health Organization announced a somewhat eminent human death pace of around 3.4 % . Still , it ’s possible that mild fount of the computer virus are being lack , which could lower the death pace . Overall , old adults and those with underlying medical conditions appear to most at risk of exposure for serious complication from COVID-19 .

Where did the coronavirus come from?
The accurate source of the new coronavirus is not known . In a new study , however , the researchers compare the genetic successiveness of SARS - CoV-2 ( formerly call 2019 - nCoV ) with those in a depository library of viral sequences , finding that the most intimately related viruses were two coronaviruses thatoriginated in bats ; both of those coronaviruses partake in 88 % of their genetic episode with SARS - CoV-2 . Another study find 96 % law of similarity between a virus find in chiropteran and SARS - CoV-2 .
Based on these results , the study authors said that SARS - CoV-2 likely grow in at-bat . However , no bats were sold at the Huanan Seafood Market , the food market in Wuhan where the outbreak is thought to have develop , which suggests that another , yet - to - be - identified animal acted as a steppingstone in transmitting the virus to humans .
A handful of studies have suggested that this " average " brute was the anteater , an endangered , ant - eating mammalian . However , virus find in sample from lawlessly trafficked anteater were not standardised enough to SARS - CoV to demonstrate that the scaly anteater were the source for the new virus , Nature describe .
This scanning electron microscope image shows SARS-Cov-2 (yellow) among human cells (pink). This virus was isolated from a patient in the U.S.
A late study indicate snakes , which were sell at the Huanan Seafood Market , as apossible source of the new computer virus . However , some experts have criticize that written report ’s analysis , saying it ’s undecipherable if coronaviruses can infect Snake .
What is the treatment?
There is no specific discussion for COVID-19 . For patients who have acquire this disease , intervention has involved " supportive care , " such as fluids and medicine to exempt symptom like shortness of breather . For severe case , treatment should admit care to defend life-sustaining electronic organ part , the CDC said . show for COVID-19 .
On Feb. 25 , U.S. officials announced that a clinical visitation to pass judgment a intervention for COVID-19 was underway , according to the National Institutes of Health . The test will quiz an antiviral drug called remdesivir in hospitalized adult who have COVID-19 . The first discipline participant is an American who caught the disease while onboard the Diamond Princess cruise ship . That person is being treated at the University of Nebraska Medical Center . The work can be adapted to examine other treatments and enroll patient at other sites in the U.S. and worldwide , officials said .
How can you protect yourself?
There is not currently a vaccinum to prevent COVID-19 . However , enquiry on a vaccine is in the works , and a trial test an experimental vaccine is sic to get down soon . Read more about theCOVID-19 vaccine trial .
The best means to prevent infection with COVID-19 is to avoid being exposed to the virus , the CDC say . In general , the CDC recommends the pursual to forbid the bed cover of respiratory virus : Wash your hand often with liquid ecstasy and water for at least 20 moment ; avoid touching your eye , nose and rima oris with unwashed hands ; fend off close touch with mass who are sick ; remain home when you are sick ; and clean house and disinfect often touched objects and surfaces .
