Cholera

CHOLERA
OVERVIEW

                It is a infectious disease so we just be treated with Antibacterial drugs are beneficial in those with severe disease to shorten its duration and severity.

INCIDIENCE

Worldwide, it affects 3–5 million people and causes 100,000–130,000 deaths a year as of 2010. New launching  Cholera was one of the earliest infections to be studied by epidemiological methods.


 DIAGNOSIS

A rapid dipstick test is available to determine the presence of V. cholerae. In those samples that test positive, further testing should be done to determine antibiotic resistance. In epidemic situations, a clinical diagnosis may be made by taking a patient history and doing a brief examination. Treatment is usually started without or before confirmation by laboratory analysis.

Stool and swab samples collected in the acute stage of the disease, before antibiotics have been administered, are the most useful specimens for laboratory diagnosis. If an epidemic of cholera is suspected, the most common causative agent is V. cholerae O1. If V. cholerae serogroup O1 is not isolated, the laboratory should test for V. cholerae O139. However, if neither of these organisms is isolated, it is necessary to send stool specimens to a reference laboratory.

Infection with V. cholerae O139 should be reported and handled in the same manner as that caused by V. cholerae O1. The associated diarrheal illness should be referred to as cholera and must be reported in the India.

PREVENTION

The World Health Organization recommends focusing on prevention, preparedness, and response to combat the spread of cholera. They also stress the importance of an effective surveillance system. Governments can play a role in all of these areas, and in preventing cholera or indirectly facilitating its spread.

Although cholera may be life-threatening, prevention of the disease is normally straightforward if proper sanitation practices are followed. In developed countries, due to nearly universal advanced water treatment and sanitation practices, cholera is no longer a major health threat. The last major outbreak of cholera in the United States occurred in 1910–1911. Effective sanitation practices, if instituted and adhered to in time, are usually sufficient to stop an epidemic. There are several points along the cholera transmission path at which its spread may be halted:[medical citation]

Sterilization: Proper disposal and treatment of infected fecal waste water produced by cholera victims and all contaminated materials (e.g. clothing, bedding, etc.) are essential. All materials that come in contact with cholera patients should be sanitized by washing in hot water, using chlorine bleach if possible. Hands that touch cholera patients or their clothing, bedding, etc., should be thoroughly cleaned and disinfected with chlorinated water or other effective antimicrobial agents.

Sewage: antibacterial treatment of general sewage by chlorine, ozone, ultraviolet light or other effective treatment before it enters the waterways or underground water supplies helps prevent undiagnosed patients from inadvertently spreading the disease.

Sources: Warnings about possible cholera contamination should be posted around contaminated water sources with directions on how to decontaminate the water (boiling, chlorination etc.) for possible use.

Water purification: All water used for drinking, washing, or cooking should be sterilized by either boiling, chlorination, ozone water treatment, ultraviolet light sterilization (e.g. by solar water disinfection), or antimicrobial filtration in any area where cholera may be present. Chlorination and boiling are often the least expensive and most effective means of halting transmission. Cloth filters or sari filtration, though very basic, have significantly reduced the occurrence of cholera when used in poor villages in Bangladesh that rely on untreated surface water. Better antimicrobial filters, like those present in advanced individual water treatment hiking kits, are most effective. Public health education and adherence to appropriate sanitation practices are of primary importance to help prevent and control transmission of cholera and other diseases.

Can Be Share Bladder In Case Of Pygopagus

                  PYGOPAGUS INTRODUCTION    Twin girls Ballenie and Bellanie Camacho, from the Dominican Republic, were born joined at the hip, known as pygopagus. Surgeons were able to separate them in a complex 22-hour procedure. What Is Pygopagus? Pygopagus is conjoined twins where the two bodies are joined at the sacrum but have separated limbs.  They can share bladders, parts of gastrointestinal tracts, and can be fused partly at the spinal cord. Only 17 percent of all conjoined twins are pygopagus.  Almost all pygopagus twins are female. Most male twins of this type are stillborn. The surgical mortality rate is lower than in most conjoined twins at 23 percent.  Pygopagus in IDENTICAL TWINS: Identical twins are formed when one single is egg is fertilized but splits into two embryos. Most conjoining occurs when the fertilized egg fails to separate completely. Pygopagus in FRATERNAL TWINS...
