Communication Breakdown
Flight Deck / Cabin / Aircraft Event Passenger Misconduct
Environment - Non Weather Related; Human Factors
In A position ZZZ-ZZZ1; several passengers approached me during deplaning to tell me that two passengers in seats XX5 and XX6 were spitting and wiping saliva; phlegm; and blood all over their seats; armrests; tray tables; window; and wall. They explained they were unable to call an FA because they saw this while standing in the aisle several rows behind these people as all passengers waited to deplane. The two passengers were able to exit the aircraft before the other passengers could notify me. I assured them the plane was terminated and would be sanitized for the evening and we agreed that the only thing remaining we could do about it was to notify Operations and request they inform the cleaners of the location to take extra precautions to protect themselves and to sanitize that area thoroughly. The blood [was] intentionally smeared into an X shape on the wall. I presumed the blood came from tearing open a scab or some other small wound. It was a clearly visible amount but didn't indicate heavy bleeding.By the time [deplaning] was complete and I could go to row XX; most of the moisture from the saliva and nasal secretions had dried and was barely visible; only the blood stood out. Without their notification; and even with the easily visible blood; it would have been impossible to realize the extent to which they had contaminated every possible surface. It would have dried completely had we taken the time to tidy the aircraft first. In our PA about passenger compliance we emphasize seat belts and smoking and perhaps that is outdated and detracts from where the emphasis currently should lie. We state federal law prohibits tampering with a lav smoke detector; perhaps we have a law that prohibits passenger misconduct and could be stated in such a way that explains the criminality (if any) to such behavior. I do not believe those passengers believed they could face any consequence for these actions. Regardless of taking place during a pandemic; at any time this behavior poses a risk to other passengers; crew; and employees.
Flight Attendant reported that two passengers were observed spitting; and wiping their saliva and blood over their entire seating area.
