A review on novel Corona virus

Abstract

Coronavirus are comes under a broad family of virus that can cause respiratory illnesses such as the common cold, according to the Centers for Disease Control and Prevention (CDC). They are usual in many different species of animals, including camels and bats. Unusually, these corona viruses can evolve and infect humans and then spread between humans. Recent examples of this include SARS-CoV and MERS-CoV. 2019 Novel Corona virus (2019-nCoV) is a virus identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China. This virus causes respiratory infections in humans, which are hourly mild but are potentially lethal. In some cases, the viruses can cause lower-respiratory tract illnesses such as pneumonia and bronchitis.  In human corona viruses are currently classified into seven types that are HCoV-229E, HCoV-OC43, HCoV-NL63, SARS-CoV, HKU1, MERS-CoV and 2019-nCoV. These two types of corona virus (MERS-CoV and SARS-CoV) are more dangerous. The Novel corona virus (2019-nCoV) is newly discovered, or newly originated, and is a placeholder name and also known as Wuhan pneumonia or Wuhan corona virus. Some of corona viruses like HCoV-229E, HCo-OC43, HCo-NL63 and HKU1 that are continuously circulate in the population of human and cause respiratory infections in human either may children and adults world-wide.  They are generally transmitted between animals and humans through sneezing, coughing, touching or shaking hands and making contact with a surface or object. The symptoms of corona virus are sneezing, cough, fatigue, runny nose, sore throat, breathing difficulty and exacerbated. In more severe cases SARS, kidney failure, pneumonia and even death. Diagnosis can be carried out by healthcare provider in laboratory test on respiratory specimens and serum to detect human corona virus. To prevention of corona virus by covering mouth and nose when sneezing and coughing, avoid unprotected contact with live animals and also washing hand with soap and water. For this virus no specific treatment like vaccines and antiviral drugs but symptoms can be treated.
