hi, thank you for your query. from the results of stool examination it seems like your daughter is suffering from E.coli infection E. coli can get into meat during processing. If the infected meat is not cooked to 160°F (71°C), the bacteria can survive and infect you when you eat the meat. Children are more likely than adults to have symptoms. Symptoms usually start 3 or 4 days after you come in contact with the E. coli. Most people get better in about a week. Treatment- -Your main treatment is to make yourself comfortable and drink sips of water. Diarrhea causes the body to lose more water than usual. This can lead to dehydration. -also continue one course of anti-biotics.for minimum of 5 days. -cow formula milk can have contamination hence use other types of milk. -give your kid adequate rest Some home tips- *Cook all types of beef, but especially ground beef, to at least 160°F (71°C). *In the kitchen, wash your hands with hot, soapy water often *Wash any tools or kitchen surfaces that have touched raw meat. *Use only pasteurized milk, dairy, and juice products. *Use only treated, or chlorinated, drinking water. *Wash your hands after you use the bathroom or change diapers. the symptoms will come down in a week. thank you, wishing you good health
