Hand washing is one of the best and most effective ways of controlling the spread of diseases – if done correctly. As we accumulate germs on our hands, we can infect ourselves with these germs by touching our eyes, mouth or nose which act as entryways into our body. Dirty hands can spread germs to others if you touch them directly, or if you touch a surface that they also touch. The best way to clean your hands is to use soap and clean running water. Alcohol-based hand sanitizers are also great at germ-killing. Antibacterial soaps are NOT recommended because they are no more effective than regular soap. Furthermore, they may induce the development of bacteria that are resistant to antibiotics. For proper hand-washing follow these simple rules:

1.  Use warm running water to wet your hands first, then apply a liquid or bar soap.
2.  Rub your hands together vigorously for at least 15 to 20 seconds, making sure that all surfaces are exposed to the soap, including your wrists, between the fingers, back of the hands and under the fingernails.
3.  Rinse well and dry with a clean or disposable towel.
4.  Turn off the faucet with a disposable towel to prevent contaminating your hands.

Marrying within one’s family is not usual practice for good reason – genetic diseases can occur more frequently. Aside from that, University of Cambridge researchers have found that children whose parents are related are more susceptible to some infections. By looking at data from certain parts of The Gambia where intra-family marriage is common, Gambian families where children had tuberculosis or hepatitis B, had parents who were significantly more likely to be related than in families with healthy children. Although more investigation needs to be done, it makes sense to think that children whose parents are related may have less diversity at the immunogenetic as well.

Creutzfeldt-Jakob disease (CJD) was widely pulicized in the 1990s as the human form of the cow disease bovine spongiform encephalopathy (BSE), which is contracted from eating contaminated beef. However, there are sporadic forms of CJD that can occur for unknown reasons – unrelated to eating meat. Now, researchers have found a new variant of this fatal disease that appears to advance faster, causing dementia and even the loss of ability to speak and move. It is yet unclear what the cause is, but scientists speculate that an interaction with a genetic component may be likely.
