If your image of WHO is the "public persona" do some home work . I have off and on since 2000. They have more mistakes and changed opinions then house democrats . Read the WHO circa 2000. on 2nd hand smoke. No statistical difference in the effects. actually the stats showed that children of smokers had LESS asthma issues ( but still not statistically significant) hey were wrong about human to human spread of the virus and the travel ban. But like liberals they change their mind and pretend they are always right
