I recall reading it and the link on that rat coronavirus. It had high morbidity and no mortality in rats...but it reduced fertility in them. I remember commenting about the potential(possible/probable - you pick) use for population control.It also affected the lacrymal glands. I remember the prefixes adeno and lacrym in the lengthy name and maybe the virus name began with an R.

Didn't someone recently post an article about the swollen & red eyes of a Vietnamese nurse survivor?

It's a bit misleading to say that SDA in rats has a low mortality rate. While technically that's true (the disease itself kills very few rats,) many rats who contract the disease outside a sterile lab setting die from secondary infections that the SDA makes them vulnerable to.

but it reduced fertility in them

....it could have started from an attempt of China experimenting for a way to reduce it's population!
