This is the number of new consultations for acute diarrhea divided by the total number of consultations. The very dramatic peak starting about week 31, 2010, demonstrates the increase in acute diarrhoea cases from the flood‐affected areas starting in KP the first week of August 2010. The “proportional morbidity” of diarrhoea in 2011 so far follows the seasonal trend of 2009 and early 2010. However the cholera cases and outbreaks are above the usual number and started earlier than usual this year. Last week 10 districts had outbreaks of AWD, 8 more were confirmed this week.

With prompt, effective treatment, Cholera mortality is less than 1%. Cholera is spread via the fecal‐oral route, most commonly by drinking water or eating food which is contaminated by sewage. Treatment • Any person with diarrhea should drink more fluids, such as water, juice, and soup. The best drink is a balanced solution of sugar and salts called ORS (oral rehydration salts) which is provided at public health facilities or can be purchased in the market and mixed with safe water to provide quick fluid replacement. Zinc supplement is also recommended. • If diarrhea is continuous or vomiting prevents drinking fluids, the patient should go urgently to a hospital or clinic to re‐ ceive intravenous fluids. Patients who are promptly treated respond rapidly and recover. Prevention • Always be sure you are drinking water is safe ‐ filtered, chlorinated, or bottled. Avoid ice in restaurants and drinks and ice cream sold in the market because they may not be made with safe water. • “Boil it, cook it, peel it or leave it” is good advice about raw fruits and vegetables in countries endemic for cholera. Cook food well, eat it hot, keep it covered, and peel fruits and vegetables. • Wash hands after using the toilet and before eating, or use an antiseptic hand gel.
