coronavirus

 coronavirus     

an outbreak of coronavirus infections in Wuhan province of China in December 2019 is threatening to emerge as the next pandemic at current count over 40,000

cases in 600 deaths have been reported in China in over 300
cases and 25 other countries unofficial modelling
 studies by a number of institutions claimed infections of over a hundred and fifty thousand the alarming speed of
                     

                                 

transmission is in part because the virus spreads through the air and by touch using the power of 3d medical animation this

video covers what
is a pandemic how this corona virus is spreading how corona virus attacks the body in what are recommended precautions

to take for protecting against epidemics pandemics indicate outbreaks of disease that spread to covered an entire region or the world a pandemic can result in massive loss of life in the last 100 years there have

been four global pandemics the worst with the 1918 influenza pandemic resulting in an estimated 50 to 100 million deaths while no global pandemic has been born from the family of corona virus to regional
                                 

epidemics have resulted from this family of viruses they include severe acute respiratory syndrome or SARS and Middle East respiratory syndrome or MERS in 2001

to 2003 and 2012 to 2015 respectively and resulted in over 1500 deaths much is yet to be known about the 2019 novel coronavirus an early study of 99 infected showed a high
                                 

mortality of 11 percent similar to SARS and ICU admission rates of 23% an earlier study described a virus pathology with an 8 day incubation period a week of infection followed by a potential escalation to

hospitalization and intensive care over another 8 to 10 days other indications put the mortality rate closer to 4% the virus has as of February 6 over 40,000 confirmed

cases in China alone with almost 200 cases in over 25 other countries however dr. Jonathan Reed from the UK leaves that the numbers of actual cases is far greater and has estimated between 170 to 300 thousand

by February 9th this is because symptoms can be mild and it's reporting and testing what's more in stark contrast to SARS some patients may be infectious in their

incubation period before the onset of any symptoms mechanism of action of corona virus the 2019 novel coronavirus is a newly discovered strain from the corona virus family that causes respiratory disease

humans have long been infected by corona virus as it is one of those responsible for the common cold it is a contagious viral infection spread through inhalation or ingestion of viral droplets as a result

coughing and sneezing and touching infected surfaces are primary sources of infection the structure of corona virus has
                                   

multiple parts inside the virus lies the genetic encoding that allows the virus to hijack human cells and turn them into virus factories a protein encapsulate the genetic

material known as the viral envelope on the surface of the viral RS in h e proteins the structure of the 2019 novel coronavirus is a mutation for more information on this

see the link below the large s glycoprotein czar used by the virus to gain entry to human cells they most likely attach to angiotensin converting enzyme to receptors on the cell membrane allowing the virus
Hi                                 

entry the exact mechanism for this is not known most likely as shown here the human cell ingest the virus in a process known as endocytosis once inside the

cytoplasm the endosome opens to reveal the virus's genetic material a single-stranded RNA the virus hijacks the cells machinery to replicate the RNA in n proteins and uses the endoplasmic

reticulum to form its M protein outer layer and the all-important S protein after replication the virus is carried by the Golgi bodies out of the cell in a process known as exocytosis so that it can infect other cells

meanwhile the stress of viral production on the endoplasmic reticulum eventually leads to apoptosis or cell death it should be noted that the mechanism of action for 20:19

novel coronavirus is unknown however scientists in China have sequenced the genome while others have used the sequencing to visualize the structure there is currently no cure or vaccine for the 2019 novel coronavirus and treatment is only

supportive therefore preventing transmission is paramount as an airborne virus recommended precautions are similar to those for preventing the flu this includes washing hands regularly with soap and water for 20 seconds covering sneezes and coughs with the inside of the elbow

refraining from touching high contact surfaces like railings and doorknobs if you use tissues throw them away immediately avoid close contact with people who are sick for more info on precautions and best practices see the list of references below the

pandemic risk of the novel coronavirus is a very real however biology has advanced greatly in the 15 years since ours and so has communication between biologists and governments China has taken monumental

efforts to contain the spread of the virus also some existing in experimental drugs are offering hope for treating the infection and improving outcomes but even still

infection control habits remain paramount if Humanity is to stave off a fall pandemic for further information see the resources listed here you
