Recommendation for mask wearing in close quarter locations
From: darren sharpe
Dear Ministry of Health,
Can you please outline the reasoning for the recommendation for wearing of face masks in public for persons transacting with the general public and operating in close proximity to other people.
Can you please provide evidence of the efficacy of the use of masks, including the efficacy of different types, the average separation required for such masks to be effective against a carrier of COVID19
Can you please confirm and provide evidence that testing has been completed on the impacts of mask wearing on the individual in respect of retention and rebreathing of bodily waste products exhaled by the individual in such circumstances.
Can you also confirm and provide evidence to support that use of a mask in the NZ external environment does not impact upon the blood oxygen levels of an individual operating in this environment
Can you also outline how the recommendation to wear a mask is appropriate given that many mask manufacturers have one or both of the following statements in reference to their products "this product does not provide protection against any virus" and "ensure professional guidance or training is obtained to ensure correct fit of this mask"; and outline how these waivers are able to be over-ridden.
