Dust: who cleans, when and how
Dust can carry allergens, micro-organisms and fungal spores. When neutrophils are low, cleaning matters, but it needs to be done the right way.

01Short answer
02Simple explanation
A damp cloth.
A filtered vacuum.
Someone else cleans.
Less clutter.
03Scientific explanation
NCI: during neutropenia a clean environment and good hygiene help reduce infection risk.
NCI: chemotherapy can lower neutrophils, platelets and red cells, which raises the risk of infection, bleeding and fatigue.
04What happens in the body?
Rugs
Rugs hold dust and mould; a small washable rug is better.
Chemicals
Mixing bleach and ammonia produces toxic gas.
Neutrophils
The first defence against infection; when they are low, hygiene matters most.
Platelets
Help blood clot; when they are low, protect yourself from injury.
05Daily protection: four steps
Wash, protect, check, report.
