In a new type of coronavirus with the beginning of the outbreak in China occurred around 150 changes.

103 the researchers analyzed publicly available genome of SARS-CoV-2 (COVID-19) and found 149 changes in strain. Most of them have happened lately.
The study showed that the coronavirus was already allocated in two subtypes: the most common L (70%) and S, which accounts for 30 percent.

Scientists say that the L subtype was more frequently found in the early stages of the outbreak in Wuhan, however, by the beginning of January, its frequency is decreased. According to the authors of the report, human disturbance had a strong selective pressure in this subtype may be more aggressive and spread faster. On the other hand, the comparative prevalence of the subtype S, which is evolutionary older and less aggressive, likely to have increased due to weaker selective pressure.

The researchers note that they analyzed data is still very limited, so for further analysis and a better understanding requires more genomic and epidemiological data, as well as information on clinical symptoms of patients with SARS-CoV-2.
