Were previous studies looking for it though?

A new paper in Nature Medicine, published June 18, documents the clinical patterns of asymptomatic infections. It finds that many of the people studied developed signs of minor lung inflammation — akin to walking pneumonia — while exhibiting no other symptoms of the coronavirus.

The study shows that being asymptomatic doesn't always mean that no damage has occurred in someone's body; follow-up studies will help researchers assess for potential long-term impacts. It also demonstrates that the intense scrutiny applied to novel coronavirus infections could shed light on how other respiratory diseases operate: Asymptomatic carriers of flu or common cold viruses are not studied much, so it's unclear whether the documented inflammation is a typical immune response or specific to the novel coronavirus.

There's also this.

Some patients with myocarditis are asymptomatic, while other may have just mild symptoms at times, including occasional chest pain or difficulty breathing. But Rodriguez is not alone: there have been multiple reports of myocarditis among college football players, putting the season in jeopardy. Already the Mid-American, PAC-12 and Big 10 have cancelled or delayed the start of the fall season.
