I can only imagine if it is difficult to obtain masks for Covid 19 droplet prevention in the UK it must be much more difficult in Zambia. [*see notes below]
Please see attached instructions for making a mask that you can insert a filter into e.g. from hoover bags which can protect against particles.
Down to 3 micron in size.
What I do know is that the masks could be adopted as a cottage industry at the very least for healthcare workers.

[*Notes from HIFA-Zambia moderator:
1. HIFA-Zambia does not carry attachments but a similar document is available here: https://www.avera.org/app/files/public/76443/Olson-Mask-with-Pattern.pdf
2. The effectiveness of cloth masks is unproven and this is a controversial area, with different people recommending different things.
3. Personally I would recommend to follow WHO advice, as this is based on the best available evidence:
- If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection.
- Wear a mask if you are coughing or sneezing.
- Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.
- If you wear a mask, then you must know how to use it and dispose of it properly.
