No coincidence sars/cov 2002 mutated and mattered as sars/cov19, in 2019 to present, some of us remember loosing loved ones in 2002 an 2003 with sudden onset diagnosis of flu,COPD, etc . They say it was contained in 2003. Like in a wuhan lab it seems... to be released as needed. We Americans know it came here then yet only now at this moment we are to worry. Wow!
