DISEASES TRANSMITTED BY COCKROACHES.

   It is well-known the damages that cockroaches produce in the food they touch and the damage is not the eaten material  but the contamination of this food by their secretions, with an unpleasant characteristic smell and the bacteria, virus and protozoarios that they carry on after having contacted with feces from the sewage system where they nest.

Cockroaches are the insects that most diseases transmit.
 

   There were found more than 30 bacteria related to cockroaches. It is true that these insects are disease transmitters, but there is no direct link between a disease and a particulary cockroach species. Some researches discovered that roaches can carry, either on the surface of their body or in their intestine, some contaminating bacteria which resident in garbage or feces they walk on and eat, producing the following diseases: leprosy, bubonic plague, dysentery, child diarrhoea, urinary and intestine infections, inflammation and pus, gastroenteritis, enteric and typhoid fever. Several studies show that cockroaches can acquire, maintain and excrete certain viruses, being vectors of infectious hepatitis.

    There is a lot of documentation on body problems because of the contact with cockroaches as dermatitis, eyelids and nose edema, steady tearing, sneezing. It is easy for people who have these symptoms to manifest in the future a breaking out of an irritation or an allergic reaction to cockroaches secretions.

It is proved that cockroaches are allergies transmitter.

    Roaches have been identified as vectors of allergies associated with asthma. The source causing the allergy to cockroaches is in their bodies, secretions, eggs and excrements contained by the house dust. There are several ways of infecting:
 
               • Inhalation of allergens residents in body and faeces, produces asthma in subjects sensitive to cockroach extracts.
                • The ingestion of food contaminated by cockroaches; it must be remembered that these allergens are thermostable, they are not affected by cooking.
                • By contact when handling or touching cockroaches, in the case of laboratories or pests cleaning workers .
                • Another way is by injection - local reactions caused by the cockroaches bites.

 A cockroach can survive more than a month with no water, or no food.
