The CDC says – only just now – that very small groups of fully vaccinated people can get together outdoors without wearing a mask – but fully vaccinated people should still wear masks if in larger groups, outdoors.
What does WHO say about masks outdoors?
WHO advises that the general public should wear a non-medical mask in indoor (e.g. shops, shared workplaces, schools – see Table 2 for details) or outdoor settings where physical distancing of at least 1 metre cannot be maintained.https://www.who.int/publications/i/item/advice-on-the-use-of-masks-in-the-community-during-home-care-and-in-healthcare-settings-in-the-context-of-the-novel-coronavirus-(2019-ncov)-outbreak/
The CDC mandates masks for everyone, everywhere, age 2 and up.
Here is what WHO recommends:
Children aged up to five years should not wear masks for source control.
For children between six and 11 years of age, a risk-based approach should be applied to the decision to use a mask; factors to be considered in the risk-based approach include intensity of SARS-CoV-2 transmission, child’s capacity to comply with the appropriate use of masks and availability of appropriate adult supervision, local social and cultural environment, and specific settings such as households with elderly relatives, or schools.
The CDC and WHO do not agree on mask usage outdoors illustrating how every jurisdiction makes up its own guidance, little of which is apparently based on common science.
The CDC also implies that children age 2 and up will be required to wear masks, outdoors – while the vaccinated adults around them do not need to wear masks. This may continue well into 2022 until vaccines are widely available for children. This advice, of course, is contrary to the advice of WHO and what is being done in nearly all other countries on earth.
