Fluoroquinolones, such as ciprofloxacin, also may be used, but resistance has been reported.Antibiotics improve outcomes in those who are both severely and not severely dehydrated. Azithromycin and tetracycline may work better than doxycycline or ciprofloxacin. Zinc supplementation
In Bangladesh zinc supplementation reduced the duration and severity of diarrhea in children with cholera when given with antibiotics and rehydration therapy as needed. It reduced the length of disease by eight hours and the amount of diarrhea stool by 10%. Supplementation appears to be also effective in both treating and preventing infectious diarrhea due to other causes among children in the developing world. Prognosis
If people with cholera are treated quickly and properly, the mortality rate is less than 1%; however, with untreated cholera, the mortality rate rises to 50–60%.For certain genetic strains of cholera, such as the one present during the 2010 epidemic in Haiti and the 2004 outbreak in India, death can occur within two hours of becoming ill. Epidemiology
Cholera affects an estimated 2.8 million people worldwide, and causes approximately 95,000 deaths a year (uncertainty range: 21,000–143,000) as of 2015. This occurs mainly in the developing world.In the early 1980s, death rates are believed to have still been higher than three million a year. It is difficult to calculate exact numbers of cases, as many go unreported due to concerns that an outbreak may have a negative impact on the tourism of a country.
The researchers theorised that either of the following situations could be antecedents to necrophilia:
The necrophiliac develops poor self-esteem, perhaps due in part to a significant loss;
(a) They are very fearful of rejection by others and they desire a sexual partner who is incapable of rejecting them; and/or
(b) They are fearful of the dead, and transform their fear—by means of reaction formation—into a desire. They develop an exciting fantasy of sex with a corpse, sometimes after exposure to a corpse. Motives
The most common motive for necrophiliacs is the possession of a partner who is unable to resist or reject them. However, in the past, necrophiliacs have expressed having more than one motive.The authors reported that of their sample of 34 genuine necrophiliacs:
68% were motivated by a desire for a non-resisting and non-rejecting partner
21% were motivated by a want for a reunion with a lost partner
15% were motivated by sexual attraction to dead people
15% were motivated by a desire for comfort or to overcome feelings of isolation
12% were motivated by a desire to remedy low self-esteem by expressing power over a corpseLesser common motives include:

Unavailability of a living partner
Compensation for a fear of women
Belief that sex with a living woman is a mortal sin
Need to achieve a feeling of total control over a sexual partner
Compliance with a command hallucination
Performance of a series of destructive acts
Expression of polymorphous perverse sexual desires
Need to perform limitless sexual activityIQ data was limited, but not abnormally low. About half of the sample had a personality disorder, and 11% of true necrophiliacs were psychotic.
