Bio-Medical Waste
“Any waste, which is generated during the diagnosis,
treatment
or
immunization of human beings /animals
or
in research activities
Or
In health camps
Hazardous health care waste
– 85% waste is non infectious
– 10% are infectious
– 5% are hazardous
Source of Health Care Waste
• Governmental Hospital
• Private Hospital
• Nursing Homes
• Physician’s Office
• Dentist Office
• Dispensaries
• Mortuaries
• Blood Bank and collection center
• Animal Houses
• Laboratories
• Research Organizations
The exposure to hazardous health care waste can
result in
1. Infection
2. Genotoxicity and Cytotoxicity
3. Chemical toxicity
4. Physical injuries
5. Public sensitivity.
Infection
The infectious agents enter in the body through
 Puncture,
 Abrasion,
 Cut in the skin;
 Through mucous membranes;
 By inhalation and ingestion.
Most Common Infections
1. Gastro enteric through faeces and/or vomit
e.g. Salmonella, Vibrio Cholera, Helminthes
Hepatitis A.
2. Respiratory through inhaled secretions
e.g. Mycobacterium tuberculosis; measles virus;
streptococcus pneumonia.
3.Ocular infections through eye secretions
e.g. Herpes virus,
4. Skin infection
e.g. Streptococcus
5. Meningitis through Cerebrospinal fluid
e.g. Neisseria meningitides
6. Blood borne diseases
• AIDS
• Septicaemia and bacteraemia
• Viral Hepatitis B & C
7. Hemorrhagic fevers

Treatment & Disposal Technologies
• 1.Incineration
• 2.Chemical Disinfection
• 3.Wet and dry thermal treatment
• 4.Microwave irradiation
• 5.Land disposal
• 6.Plasma pyrolysis
Conclusion
• Thus refuse disposal cannot be solved without public
education.
• Individual participation is required.
• Municipality and government should pay importance to
disposal of waste economically.
• Thus educating and motivating oneself first is important and
then preach others about it.

Editor's Notes

  • #7 Inadequate waste management thus will cause environmental pollution, unpleasant smell, growth and multiplication of vectors like insects, rodents and worms and may lead to the transmission of diseases like typhoid, cholera, hepatitis and AIDS through injuries from syringes and needles contaminated with human. Although there are no exhaustive documented studies on health hazards associated with poor hospital waste management, some indicators like progressive increase in hospital infection rate, increasing resistance to wide variety of antibiotics are the pointers to the way in which poor hospital waste management can contribute to the ill health plaguing the health care institutions.   In addition to health risks associated with the poor management of bio-medical waste, due consideration must be given to the impact on environment, especially to the risks of pollution of water, air and soil. Hence, collection and disposal of waste in the proper manner is of great importance as it can decrease directly and indirectly health risk to people, and damage to flora, fauna and the environment 
  • #8 Commonest infections, which can result from mishandling of hospital/health care waste, are gastro enteric through faeces and/or vomit (Salmonella, Shigella spp., Vibrio Cholera, Helminthes; Hepatitis A), Respiratory through inhaled secretions; saliva (Mycobacterium tuberculosis; measles virus; streptococcus pneumonae), Ocular infections through eye secretions (Herpes virus), Genital infections (Neisseria gonnorrhoeae; herpes virus), Skin infection through pus (Streptococcus spp.), meningitis through Cerebrospinal fluid (neisseria meningitides), AIDS through blood and sexual secretions (HIV), Haemorrhagic fevers through body fluids (Junin, Lassa, Ebola and Marburg viruses), Septicaemia and  bacteraemia through blood (staphylococcus aureus, Enterococcus, enterobacter, klebsiella and streptococcus) and Viral Hepatitis B & C through blood and body fluids (hepatitis B and C viruses).
