Chemspec recommend
prekleen initial application followed by enz-all for protein based stains. I would suggest using a broad spectrum antibacterial/antiviral (like formula 429) initially spray around the area and leave to dwell for 30 minutes. Remove wet soil (if present)with disposable scoop into plastic bag and seal. Wipe area with disposable cloths and dispose into bag and seal. Apply enz-all and/ or prekleen and agitate. Do not overwet as this will drive the soiling into the backing of the carpet. Agitate by hand with a disposable brush if possible. Otherwise use your carpet agitator and strip down and sanitise afterwards. HWE extract with de-foamer, rinse-x, some antibacterial and deodoriser mixed into the rinsing solution. Strip down and sanitise after use. Spray some kill odour citrus or enzyme urine treatment onto the area and leave. If the stain persists try some anti browning spotter and agitate and use terry towelling to absorb the stain and throw away, then HWE. Then apply odour treatment. Many odour treatments continue to work long after cleaning to continually treat the bacteria that thrive on any residue.
As far as ppe is concerned I would suggest overshoes, gloves (put these on before you ring the doorbell), a disposable face mask as a minimum. I always wear a disposable suit and white wellies (for indoor use only) which I can sanitise afterwards. Everything disposable goes in a yellow contamination bag so I know which one is the riskiest waste.
Think this is overkill? Remember you can't be too careful with your health. The most common pathogens are c. Diff, e coli and Staphylococcus aureus. Many of these are antibiotic resistant.
