These measures are also recommended for those who may handle objects contaminated by an infected persons body fluids. In 2014, the CDC began recommending that medical personnel receive training on the proper suit-up and removal of personal protective equipment (PPE); in addition, a designated person, appropriately trained in biosafety, should be watching each step of these procedures to ensure they are done correctly. In Sierra Leone, the typical training period for the use of such safety equipment lasts approximately 12 days. Patients and household members
The infected person should be in barrier-isolation from other people. All equipment, medical waste, patient waste and surfaces that may have come into contact with body fluids need to be disinfected. During the 2014 outbreak, kits were put together to help families treat Ebola disease in their homes, which included protective clothing as well as chlorine powder and other cleaning supplies. Education of caregivers in these techniques, and providing such barrier-separation supplies has been a priority of Doctors Without Borders. Disinfection
Ebolaviruses can be eliminated with heat (heating for 30 to 60 minutes at 60 °C or boiling for five minutes). To disinfect surfaces, some lipid solvents such as some alcohol-based products, detergents, sodium hypochlorite (bleach) or calcium hypochlorite (bleaching powder), and other suitable disinfectants may be used at appropriate concentrations. General population
Education of the general public about the risk factors for Ebola infection and of the protective measures individuals may take to prevent infection is recommended by the World Health Organization.

Genetics
ALD is caused by mutations in ABCD1, located at Xq28 and demonstrates X-linked recessive inheritance. The gene ABCD1 encodes a peroxisomal membrane transporter which is responsible for transporting very long chain fatty acid substrate into the peroxisomes for degradation. Mutations in this gene that interfere with this process cause this syndrome.Males with an ABCD1 mutation are hemizygous, as they only have a single X chromosome. Female carriers will typically avoid the most severe manifestations of the disease, but often become symptomatic later in life. Although the detection of an ABCD1 mutation identifies an individual who is affected with a form of ALD, there is no genotype–phenotype correlation. Within a family, there will often be several different phenotypes, despite the presence of the same causative mutation. In one case, a family with six affected members displayed five different phenotypes. There are no common mutations that cause ALD, most are private or familial. Almost 600 different mutations have been identified, approximately half are missense mutations, one quarter are frameshifts, with in-frame deletions and splicing defects making up the remainder. The incidence of new mutations in ALD (those occurring spontaneously, rather than being inherited from a carrier parent) is estimated at 4.1%, with the possibility that these are due to germline mosaicism. Pathogenesis
The exact cause for the varied collection of symptoms found in the different ALD phenotypes is not clear. The white matter of the brain, the Leydig cells of the testes and the adrenal cortex are the most severely affected systems.
