CDC Director Rochelle Walensky LIES: Face masks supposed to be 80% effective

Next to the lies about the absurdly inflated efficacy of surgical masks, she also keeps spreading the misinformation about hand washing. Where is the proof? The authorities have absolutely lost ALL credibility due to their own continued spread of disinformation. Instead of acknowledging the errors of their way, they have doubled up. They are in a hole and continue to dig.

The best available evidence shows that respiratory viruses are mostly spread in badly ventilated indoor areas with high population density and low humidity where people spend a prolonged period of time. The most effective and least harmful prevention measures are adequate ventilation and optimal humidity (40%-60%).
