Occupational infections

Needlestick injuries contribute to 39%, 37% and 4.4% of hepatitis C, hepatitis B and HIV infections respectively (1).

The prevalence of acute hepatitis B infection among health workers globally is 5.3% (2).

About 54% of health workers in low- and middle-income countries have latent TB infection (3).

Preventive measures


Adhere to strict infection prevention and control measures

Observe standard precautions for infection control - hand washing, respiratory hygiene, safe collection and disposal of health-care waste, environmental hygiene and use of personal protective equipment

Use safety-engineered devices and follow good practices for safe injections

Provide immunization at no cost to health workers. WHO recommendations on health workers’ vaccinations include Bacillus Calmette–Guérin (BCG), hepatitis B, polio, pertussis, diphtheria, measles, rubella, meningococcal, influenza, varicella, COVID-19 and cholera

Provide systematic latent TB infection testing and treatment for health workers in countries with a low TB incidence

Ensure adequate ventilation in all indoor health-care settings

Consider the use of ultraviolet germicidal irradiation (UVGI) for disinfection and prevention of airborne pathogens

Use clinical triage for early identification of patients with respiratory infections to prevent transmission

Ensure adequate supply, proper use and maintenance of well fitted personal protective equipment
