"As soon as your body notices an infection, it immediately tries to grow a response while the virus tries to grow itself. From then on, it is a race to see which can grow biggest fastest. And the virus gets a big advantage in this race if its initial dose of infecting virus is larger. This effect is widely known and acknowledged by experts, and it is one of the main rationales given for wearing masks, gloves etc. Thatโ€™s not just to cut the chance of an infection, but also to cut the initial dose."

The Case for Universal Cloth Mask Adoption and Policies to Increase Supply of Medical Masks for Health Workers
๐Ÿ”—https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3567438
"We recommend the immediate universal adoption of cloth facemasks, including homemade, and accompanying policies to increase the supply of medical masks for health workers. Universal adoption will likely slow the spread of the COVID-19 virus by reducing transmission from asymptomatic individuals. We provide strongly suggestive evidence from cross-country data that facemask use slows the growth rate of cases and deaths."ย 

Professional and Home-Made Face Masks Reduce Exposure to Respiratory Infections among the h Population
๐Ÿ”—https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2440799/
Written in 2008 and not specifically about COVID-19. From the abstract:
"All types of masks reduced aerosol exposure, relatively stable over time, unaffected by duration of wear or type of activity, but with a high degree of individual variation. Personal respirators were more efficient than surgical masks, which were more efficient than home-made masks. Regardless of mask type, children were less well protected. Outward protection (mask wearing by a mechanical head) was less effective than inward protection (mask wearing by healthy volunteers)."
