Flu or Bioweapon?

The COVID-19 is a novelty and a mystery. Is it the virus in 2012 found in horseshoe bats in Yunnan, 1000 miles of Wuhan? Or is it a lab-engineered virus? A dangerous bioweapon because it is unknown, spreads twice as fast as SARS-COV and is deadly.
COVID-19 is family of SARS-CoV and MERS-CoV. The SARS epidemic of 2002-2003, which infected 8,098 people worldwide, killed 774 of them. That is 9.5 per cent. And the MERS outbreak that began on the Arabian Peninsula in 2012 and still lingers infected 2,506 people and caused 862 deaths per 15 January 2020. That is close to a 35 per cent mortality rate.
