There is not much information on this, but it seems that there is an outbreak of pneumonia, which so far is only in children, in China, and has led to thousands being hospitalised. The infection seems to be treatable with existing antibiotics, so it is not a super-bug type of infection. There have been reports that this type of pneumonia was somewhat different to standard pneumonia, and it could be a new variant, but not one of major concern, at least for the West. Internet claims that this could be the start of the next type of plandemic, seem misplaced, since the next plandemic will surely be scheduled in time for the 2024 US elections given that Donald Trump is so far ahead in the polls.
