Infection control materials

Yes. Vaccinia vaccine is recommended for laboratory workers who directly handle cultures, animals contaminated or infected with, nonhighly attenuated vaccinia virus, recombinant vaccinia viruses derived from nonhighly attenuated vaccinia strains, or other orthopoxviruses that infect humans. These would include monkeypox, cowpox, vaccinia, and variola. Other health-care workers, such as physicians and nurses whose contact with nonhighly attenuated vaccinia viruses is limited to contaminated materials such as medical dressings but who adhere to appropriate infection control measures, are at lower risk for accidental infection than laboratory workers. However, because a theoretical risk for infection exists, vaccination can be offered to this group. Vaccination is not recommended for people who do not directly handle nonhighly attenuated virus cultures or materials or who do not work with animals contaminated or infected with these viruses. 

What to do Ensure that land is well-drained. When growing vegetables, use a strict crop rotation. Control woundforming pests like wireworms, slugs, and root-damaging larvae. Once rot has started, there is no cure. Dispose of or bury infected plant material.

Specimens that are analyzed for QC purposes are called control materials. They are required to be stable, available in aliquots or vials, and amenable to being analyzed periodically over a long time. There should be little vial-to-vial variation so that differences between repeated measurements are attributed to the analytical method alone. The control material should preferably have the same matrix as the test specimens of interest (e.g., a protein matrix may be best when serum is the test material to be analyzed by the analytical method) Materials from human sources have generally been preferred, but because there is some risk of hepatitis infection, bovine materials offer a certain advantage in safety and are more readily available. The concentration of analyte should be in the normal and abnormal ranges, corresponding to concentrations that are critical in the medical interpretation of the test results. 

In addition to vaccinating health care workers against hepatitis B, other infection control practices are important in preventing transmission of the virus because up to 10% of people do not develop an adequate antibody response to the vaccine. The most important infection control measure is the use of universal precautions. These precautions prevent exposure to blood and blood-derived body fluids via use of a variety of barrier precautions, measures to prevent needlesticks, environmental control measures, and good hand-washing techniques. However, if a worker is exposed to material that potentially contains HBV, recommendations for percutaneous exposure to HBV should be followed (see Table 40-7). ... 

In conjunction with the World Health Organization, CDC has developed practical. hospilal ba.sed guidelines, titled Infection Control for Viral Haemorrhagic Fevers In the African Health Care Setting. The manual can help health-care facilities recognize cases and prevent further hospital-based disease transmission using locally available materials and few financial resources. 

Universal precautions—An OSHA term for the method of infection control in which all human blood and certain other materials are treated as infectious for bloodborne pathogens. 

Universal precautions is a method of infection control in which all human blood and certain human body fluids are treated as if known to be infectious for HIV, HBV, and other bloodborne pathogens. Universal precautions are to be observed in all situations where there is a potential for contact with blood or other potentially infectious material.

Biological materials may introduce three distinct health hazards to museum workers. Live micro-organisms and viruses may cause infection. Organic material, either whole micro-organisms (live or dead), or the constituent parts of biological systems (e.g. proteins), may cause allergic reactions. Finally, the products of biological systems may be toxic. This chapter is concerned with where these hazards may arise and with how they should be controlled.
