ersonal Protective Equipment (PPE) Basic hygiene (hands and surface) ( ) Use PPE in a targeted and situational manner. Depending on the risk of contamination, gloves, protective gowns, face masks or safety goggles may be required, regardless of the pathogen. Examples: Contact with blood, secretions/excretions, extensive wound care Contact protection measures/ contact isolation ( ) Use disposable med. gloves and protective gowns. Depending on the pathogen and clinical picture, protective goggles and a face mask may also be required. Examples: MRSA, Droplet isolation (short-range transmission) ( ) Use disposable med. gloves, protective gowns and face mask. Depending on the pathogen and clinical picture, protective goggles may also be required. Example: Whooping cough Aerogenic isolation (long-range transmission) ( ) Use disposable med. gloves, protective gown, respirator (e. g. FFP-2). Depending on the pathogen and clinical picture, protective goggles may be required. Examples: Overt tuberculosis of the respiratory tract, measles Special isolation station Generally use of blower protection suits. Examples: Ebola, Marburg virus Pathogen Category Spectrum of activity Main route of infection Hygiene measures Typical symptoms/clinical picture 3-MRGN Acinetobacter baumannii bactericidal 1 Catheter-associated urinary tract infections and pneumonia, wound and soft-tissue infections, sepsis 4-MRGN Acinetobacter baumannii bactericidal 2 Catheter-associated urinary tract infections and pneumonia, wound and soft-tissue infections, sepsis Adenovirus limited spectrum virucidal activity a (Kerato-)Conjunctivitis, gastroenteritis, pharyngitis, respiratory tract infections/pneumoniaa, pharyngoconjunctival fever, follicular conjunctivitis Aspergillus spp. fungicidal Aspergillosis, sinusitis, pneumonia Bacillus anthracis sporicidal a Anthrax Bordetella pertussis bactericidal Whooping cough Borrelia spp. bactericidal Borreliose (Lyme disease, lice relapsing fever, tick relapsing fever) Brucella spp. bactericidal Brucellosis Burkholderia mallei bactericidal Glanders, malleus Burkholderia pseudomallei bactericidal Melioidosis Burkholderia cepacia bactericidal Respiratory tract infections, catheter-associated urinary tract infections (CAVE: exclude contaminated care products) Campylobacter jejuni/coli bactericidal 3 Gastroenteritis Candida albicans yeasticidal Mucosal or skin candidiasis, organ candidiasis, candidaemia Candidozyma auris (formerly: Candida) yeasticidal 4 Candidiasis, Candidaemia Chikungunya virus (CHIKV) virucidal activity against enveloped viruses Chikungunya fever Chlamydia psittaci bactericidal Ornithosis/Psittacosis Chlamydia trachomatis bactericidal Trachoma, urogenital tract infections 3-MRGN Citrobacter spp. bactericidal 1 Urinary tract infections, wound infections, sepsis 4-MRGN Citrobacter spp. bactericidal 2 Urinary tract infections, wound infections, sepsis sporicidal ( ) 5 -associated diarrhea (CDI) Clostridium tetani sporicidal Tetanus Coronavirus (not SARS-CoV-2) virucidal activity against enveloped viruses Respiratory tract infections, sniffle, bronchitis Corynebacterium diphtheriae bactericidal a b Cutaneous diphteriaa, pharyngeal diphtheriab Coxiella burnetii bactericidal Q-fever pneumonia Coxsackie virus virucidal activity Hand-mouth-foot disease, respiratory tract infections, myocarditis, meningitis Crimean Congo haemorrhagic fever virus—(CCHFV) virucidal activity against enveloped viruses Viral hemorrhagic fever, hepatitis, encephalitis From A for Acinetobacter to Z for Zika virus New overview of relevant pathogens in healthcare and the associated hygiene measures What spectrum of activity do I need when dealing with hepatitis A viruses? And what isolation measures must be observed for a patient with a 4-MRGN pathogen? These and other questions are answered in a new overview poster from the HARTMANN SCIENCE CENTER. In addition to spectra of activity and transmission routes, the information poster focuses primarily on the necessary hygiene measures, including the required personal protective equipment.
