For SARS (2003) It took 3 years to find the intermediate host (civets). And 14 years (2017) to find the bat parent of the virus[1].

Guess who found the bat host? Shi Zhengli of the very WIV in question.

That's a bit confusing because the OP makes an opposite point: "The intermediary host species of SARS1 was identified within four months of the epidemic’s outbreak, and the host of MERS within nine months."

That wikipedia article says

> In late May 2003, studies were conducted using samples of wild animals sold as food in the local market in Guangdong, China. The results found that the SARS coronavirus could be isolated from masked palm civets (Paguma sp.)

and

> The SARS epidemic began in the Guangdong province of China in November 2002 ... Chinese government officials did not inform the World Health Organization of the outbreak until February 2003.

That's six months from the start of the outbreak, and less than four months from WHO being informed, not three years.

Where did you get your "three years" figure from?

In 2003 it was merely suspected that covers were the intermediate. It wasn't confirmed until 2006. Read further down:

"In late 2006, scientists from the Chinese Centre for Disease Control and Prevention of Hong Kong University and the Guangzhou Centre for Disease Control and Prevention established a genetic link between the SARS coronavirus appearing in civets and humans, bearing out claims that the disease had jumped across species.[62]"

It goes on to state that the bat link was confirmed in 2017.

It's pretty unclear exactly what was proved in 2003 and in 2006. But the point remains: for COVID19, after a year of searching we don't even have a suspect animal host.

Sars reemerged twice between 2003 and 2006, once in 2004 from civets and once in 2005 from an accidental lab release. Another potential outbreak in 2005 was prevented by preemptively culling civets when a high titre of SARS coronavirus was discovered. And civets eventually lead to the actual source on bats.
