•  It’s the seventh corona virus found to cause illness in humans and previous corona viruses that have caused human epidemics include SARS and MERS viruses.

•  The new corona virus itself is a novel beta corona virus and it’s in group 2b
•  It’s a RNA virus and it’s been shown through genetic analyses tobe almost like bat corona viruses.

• In fact it’s been shown to be 96% related to bat corona viruses.

• So originally it was believed that the virus originated from transmission from snakes to humans now it seems to be from bats to humans but it’s still unsure if there’s a separate species in between that mechanism so what I mean by that’s bats are likely the first source but we’re not sure if bats transmitted to a different species which transmit it to humans or bats directly transmitted the virus to humans so we’ll be waiting on further evidence to ascertain where or how the virus is transmitted.

• This Wu hen corona virus shares an approximately 80 percent sequence homology with the severe acute respiratory syndrome or SARS coronavirus so there are similarities between this Crona virus in SARS corona virus but there are things that aren’t similar we’ll mention that later also. 

• Why this is often important now’s that the World Health Organization or WHO has recently declared a public health emergency for this 2019 novel coronavirus and that they  declared this public emergency on January 30th 2020.

 What are the origins of coronavirus (COVID-19) :

•  The origins all start in Wuhan, Hubei china.

• Wu hen may be a city of quite 11 million people it is a relatively large city it is the seventh largest city in China.

•  Hubei province is itself home to over 50 million people.

•  What happened was there have been cases that began to occur in December of 2019 and that they  were deemed pneumonia of unknown cause.

• The first patients with this new corona virus seem to possess been hospitalized on December 16th 2019 in order that was the primary date we all know of thus far.

• But it’s estimated that initial infections started to occur even before this probably as early as November 2019.

• After multiple sporadic cases began to increase throughout Hubei China in across China this virus was reported to the WHO and it had been reported to the WHO on December 31st 2019.

• So it all begins or is assumed to possess began in the huanan and seafood market now huanan and seafood market was initially the place where this was thought to possess  originated through cross species contamination or through transmission from a bat to a person’s because most of the initial patients with this virus worked or had visited this seafood market so it’s unsure of at now  whether this is often the first source of the infection.

Subsequent cases: 

• Involved healthcare workers that had been exposed to those  patients and relations of patients.

•  This all raised the likelihood of human-to-human transmission.

• It was again initially believed to be transmitted from the first source example the market .

• But over time it had been  postulated and now has been shown to be transmitted at least  from human to human as a possible mechanism.

•  We’re still not sure if it’s transmitted from the original source still and transmitted human-human or if it’s just being transmitted human to human so human human transmission has been demonstrated in said countries China,Germany, united states and Vietnam and it originally was believed to be transmitted between symptomatic patients so a individual could only transmit it if they were sick and they were developing or showing symptoms.

• There was one report that demonstrated 5 cases of the 20-19 corona virus that seemed to be transmitted by Asymptomatic patients so right now we’re still unsure exactly how this is often being transmitted is it being transmitted human to human only through symptomatic cases or can it be transmitted through both symptomatic and asymptomatic patients so we’re still not sure at now but there’s that one report which will suggest that it can be transmitted even through asymptomatic individuals who are carrying the virus.

• So this is often all led to the present outbreak and the epidemic or the outbreak is approximately doubling every seven day.

• Occurring through respiratory droplets so exposure to sneezing and coughing this is often very similar to other respiratory viruses so other rhinoviruses other corona viruses seem to be spread by this also so respiratory droplets.

• It might be transmitted airborne a minimum of within the vicinity of the respiratory droplets.

• It’s probably requiring some close contact with an infected individual so close contact is defined as being within 6 feet or 2 meters.

• It’s probably more likely that you simply need some prolonged period of your time to be in close contact with that individual to possess that effective transmission and may be transmitted through indirect objects like fomites so if the respiratory droplet lands on some object and a private touches that object and touches their nose or face they could have a transmission through that mechanism.

•  A newer way that it has been  shown that it can possibly spread and it is possibly transmitted is through feces.

• Actually the corona virus has been shown to be within the feces or loose stool of a patient in Washington US.
