Spotters in "Environment and Health: Fly control measurers " for CFM & MPH students

-
Image
1. Environmental control: Important points: The best way to control houseflies is to eliminate their breeding places & environmental sanitation. A clean house with clean surroundings is the best answer to the fly problem. Storing garbage, kitchen wastes, and other refuse in bins with tight lids, pending disposal. Efficient collection, removal & disposal of refuse by incineration, composting & sanitary landfill. Provision of Sanitary latrines, e.g, pit privies, septic tanks, water-seal latrines & sanitary system. Stopping open-air defecation. Sanitary disposal of animal excreta. Stepping up general sanitation.  2. Insecticidal control: Important points: Insecticides are only a supplement, but not a substitute for sanitation. (i) Residual sprays: It showed resistance to DDT in 1948 & also developed resistance to other organochlorines, organophosphorus, and carbamate pesticides. Susceptible flies may be killed by DDT (5%), methoxychlor (5%), lindane (0.5%), or chlo...

ORS : A boon in dehydration

-
Image
What is ORS? Oral re-hydration salts: It is a glucose-electrolyte formula given by WHO/UNICEF, used for correction of acute diarrhea due to all causes and dehydration in all age groups with aim to reduce mortality. It is available in powder form in sachets/ ready-made solution or it can be easily made at home. How it works? The combination of electrolytes and sugar together stimulates water and electrolyte absorption from the gut and hence  capable of correcting water and electrolyte deficit in conditions such as diarrhea and vomiting. Reasons to celebrate ORS day? ORS Day is celebrated every year on 29th July:  To spread awareness about the importance of Oral Rehydration Salts (ORS) as a low cost method of health intervention.   Among infants and young children, acute diarrhoeal diseases are one of the leading causes of mortality in many developing countries.   Dehydration particularly affects infants, children and old people.  Diarrhea...

If not recognized early and managed promptly, it can lead to septic shock, multiple organ failure and death.  What is the need of awareness? Sepsis is a syndromic response to infection and is mostly a final common pathway to death from many infectious diseases worldwide particularly in low- and middle-income countries where it represents a major cause of maternal and neonatal morbidity and mortality. Sepsis patients with resistant pathogens have been found to have a higher risk of hospital mortality.  When is it celebrated?
