scientists research of corona virus vaccine (covid19)

scientists study of corona virus ,,the corona virus has mutated and the second strain is more aggressive then the original.a group of scientists and researchers documented published in late february.

• it analysis 103 cases from  around the world with the mejority of them from china,s hubie province where the virus first appeared. keep in mind viruses are always mutating particularly (R.N.A)viruses such as the covid 19 corona viruses however a genetic analysis of the cases showed that the covid 19 corona virus evolved into two MAJOR types THE *S* type corona virus  and THE *L* type corona virus  THE *S* type which had infected about 30 percent of cases examines is considered to be the older of the two and is likely to have appeared when the virus jumped from animals to humans .THE *L* type are infected around 70 percent of the cases is thought to have amarged  afterworsds .*L* CORONA VIRUS COVID 19 might be more aggressive then the *S* TYPE OF corona virus  .due to the potentially higher transmission or replication ..so should we be even more worried ? in an article published by new scientist magazine IAN.PROFFESOR JONES .he said .the differences between the two identified strains are tiny and so want change the way the virus works .

          rather then the virus itself however the report by the chinese scientist also revealed that although the*L* type of corona virus was the more aggressive of the two strains the relative frequency of the*L* type decrease compared to the*S*type of corona virus covid 19 .because china,s government rapidly prevention a control measures .however the report cautions that the sample size was limited -and more data is required for further analysis particularly as the virus spreads epidemiologists widely agree that once infected with the corona virus covid 19 a patients are unlikely to catch it again unless the virus mutates to such a point that it can overcome over immune defence .the best way to prevnt them is to gather as much data as possible --and keeps and keeps tabs the number of mutations as scientists race to developed a vaccine for this fast spreading corona virus covid 19 .https://www.bbc.com/news/health-51665497

corona symptoms

if you have this type of  sysmptoms  like fever, cough,fatigue, aches pains sore throat ,headaches,chills ,nose,nasal  congestion diarrhea then do not ignore them because  this is the symptoms of covid 19 or corona virus  

but according to miss julia belluz who is a senior health reporter she say,

=====based on data  from china the vast mejority of cases are not life threating 80./. percent cases mild cases up to mild poneumonia 20./. percent severe  she further say about corona virus ,severe respiratory problems it can develop in to quite a severe poneumonia --                                                                                       corona virus case fatality by age ,,
