how do you get the coronavirus ?-coronavirus symptoms /Medical Microbiology

Coronavirus

coronavirus is distributed all over the world .People always ask  about coronavirus causes , what caused the coronavirus ,what  dose the disease develop from coronavirus? , coronavirus symptoms , how is coronavirus diagnosis ? should i go to the doctor for coronavirus ,how to treat coronavirus symptoms ?who to see with virus ? and how do you get the coronavirus ?

in this article we will answer all this question.

Coronavirus structure:

Coronavirus is a positive-sense single-stranded ribonucleic acid belongs to the virus the subfamily Orthocoronavirinae among the family Coronaviridae. It is a spherical enclosed virus with spikes prominent so it named as corona .Corona means that crown in Greek. 

coronavirus size from 118 to 114 nm.It's considered a large particle virus .Any virus can't replicate outside living organisms thus starts replication once enters the human or  animal body.

coronavirus presence:

Coronavirinae subfamily presents wide between mammals .It causes illness in respiratory and digestive the system.  This illness range from gentle to severe. Scientists isolated quite sixty coronaviruses from bats and most of them belonged to the genus betacoronavirus. 

The first-time scientist isolate coronavirus was in 1930. The virus was isolated from poultry inflicting infectious bronchitis .It had been simple pathogens to humans till 2003 once sars appeared. 

Severe acute respiratory syndrome(SARS):

Means that severe acute respiratory syndrome.It appeared in china and transmitted from civet cats to humans and 8000 cases were reportable worldwide.

East Respiratory Syndrome or (MERS):

Another kind of coronavirus caused outbreak appeared in Saudi Arabia in 2012 and named as Middle East Respiratory Syndrome or MERS. 

The illness seems within the variety of severe respiratory disorders with symptoms of fever, cough, and shortness of breath. The case death rate was 30% and every case  connected to the Arabian peninsula and transmitted from dromedary camels to humans.

COVID-19:

The new kind of coronavirus appeared in china in 2019 and named as COVID-19 and also the outbreak was declared on thirty Jan 2020. COVID-19  spread from one city to the whole country in just thirty days.

Origen

In the preliminary report, complete infectious agent genome analysis reveals that the virus shares 88% sequence identity to 2 bat-derived severe acute respiratory syndrome (SARS)-like coronaviruses. However additional distant from severe acute respiratory syndrome coronavirus (SARS-CoV).

It's thought that infection was connected to seafood and live animal market. It transmitted from animal to human at first ,however currently it's transmitted from human to human simply. The disease clinical signs appear as respiratory symptoms, fever, cough, shortness of breath and respiratory difficulties. In some cases, the severity of coronavirus appears after 10 days from the start of symptoms and cause respiratory disease, renal failure and will reach to death.

People in danger from COVID-19:

Old people 

individuals with chronic diseases like cardiovascular disease diabetes lung disease.

The death rate of coronavirus 2.3%.There were not death between youngsters in 9 years old and younger .Cases in those aged seventy to seventy nine years had 8.0% CFR and cases in those aged eighty years and older had a 14.8% CFR.

coronavirus transmission from mother to baby in late gestation:

A study has been made on 9 pregnant women in late gestation to get if COVID-19 transmit from pregnant woman to her baby or not. They found that babies were born in good condition .They made the test for COVID-19 to newborns and breast milk and therefore the results were negative. So scientist assumes that coronavirus (COVID-19) does not transmit by vertical transmission.

According to world meter on March 17, 2020, 22:54 GMT Coronavirus Cases 198,092 Deaths 7,961 Recovered 81,727

How am I able to avoid COVID-19 infection?

1-By alcohol or washing your hand with soap and water for a minimum of twenty seconds .They able to kill the virus 
2- Avoid touching mucous membranes without washing your hand. 
3-Create a secure distance between you and others that at least meter,
4- cover your nose with a tissue or mask 
5-If you feel sick and have signs that we have got mentioned you ought to call a doctor or attend the hospital.

Researches about coronavirus treatment:

The latest researches that have been made regarding the treatment of COVID-19 showed that chloroquine phosphate,  is shown to possess apparent effectiveness and acceptable safety against COVID-19 associated pneumonia . 

chloroquine phosphate  is a previous drug for the treatment of protozoal infection,The drug is suggested to be included within the next version of the rules for the hindrance, diagnosis, and treatment of pneumonia caused by COVID-19 .

Differential diagnosis between coronavirus and different diseases have similar symptoms:

Common cold causes stuffy nose, runny nose and sneeze .Influenza causes stuffy nose, runny nose, sore throat, and dry cough then muscle ache, high fever, and discomfort appear however in mild coronavirus infection (COVID-19 ) clinical symptoms are cough or not sore throat then fever appears and in sever cases difficult respiration, confusion , muscle ache and headache appear.
