I am writing this article as a way to promote our fly killer machines. It gives information about the diseases that houseflies can cause.
Houseflies frequently use dung piles and other excrement sources. They also visit rotting items, including dead animals. When placed on food prepared for human consumption, contaminated material often contaminates the food.
There are a wide variety of diseases that can be transmitted by flies. Some of those:
Typhoid fever (Salmonella typhi)
Symptoms: High temperature (up to 104°F or 40°C), loss of appetite, headache, stomach pain, and often some weakness. Sometimes a pink skin rash appears.
Treatment: The doctor will usually prescribe an antibiotic and the symptoms will subside within a few days. If no treatment is given, the subject may become seriously ill or even die from secondary problems (up to 20% of typhoid patients die without treatment).
Cholera (caused by Vibria cholerae, a bacterium)
Symptoms: unexpected episodes of watery diarrhea with patches of white mucus material, stomach pains, dry or sticky mouth, sunken eyes, concentrated colored urine, markedly sunken fontanelle (soft spot on the top of the head) in a child, dry skin, nausea and vomiting (usually).
Treatment: Cases can range from mild to severe. If left untreated, severe cases can lead to imminent death. Drink plenty of fresh water mixed with a small amount of salt and sugar. This will restore the body’s fluid. Immediate treatment should be given.
Symptoms: This depends on the strain of Escherichia coli. Most strains are harmless and cause no detectable symptoms. Other strains such as O157:H7 can sometimes cause bloody diarrhea. In a very few cases, Escherichia coli O157:H7 can cause hemolytic uremic syndrome, which can lead to kidney failure in young children. For most of us, and most of the time, Escherichia coli is not a problem.
Treatment: No treatment is required unless uremic syndrome occurs, which may require blood transfusion and kidney dialysis.
Shigellosis (caused by Shigella, a bacterium)
Symptoms: Diarrhea (often bloody), fever and stomach aches. Most cases are mild and go unnoticed. In a small number of cases, the very young and the very old may be vulnerable to high temperature fever, possibly (and rarely) causing a seizure in a toddler.
These are just a few of the diseases houseflies can spread. Be careful. To be safe you may want to install a fly killer (details below).
