Deer ticks carry many diseases. Some cervid ticks carry a disease known as Lyme Disease. Lyme Disease became known in 1975 in the town of Lyme. Connecticut. Many people began enduring from arthritis and holding skin roseolas on their organic structure. Medical research workers shortly found that cervid ticks carry the disease. After a piece. Lyme Disease became curable. A tick has to be attached to a giver organic structure for 24 hours to convey Lyme Disease. The first symptom that occurs after being spot by the tick is a little ruddy roseola at the sight of the bite. This roseola expands and subsequently might look on different sights on the organic structure. This ruddy roseola is known as erythema migrans. Erythema migrans can besides do febrility. concern. stiff cervix. and organic structure aching. The following symptom that might happen is arthritis. Arthritis normally occurs after a few months of being infected. Some of the other symptoms include terrible concern and palsy of facial musculuss. It is rare. but if Lyme Disease is non treated over a longer period of clip. the victim my dice.

West Nile Encephalitis is a disease that was seen foremost in the U. S. in 1999 when it infected 62 people and killed 7 of them. West Nile Encephalitis is caused by mosquitoes who originated in Africa. West Nile Encephalitis is an infection of the encephalon caused by the West Nile Virus. a virus found in Africa. Eastern Europe. and West Asia. It is a enigma how West Nile Encephalitis came to the U. S. Some of the possibilities are that septic birds migrated to the U. S. Another possibility is that an septic homo traveled here and was bitten by a mosquito here. which so infected more and more people. The symptoms of West Nile Encephalitis are flu-like infections. These are really similar to the symptoms that occur from Lyme Disease.

Equine Encephalitis is a rare disease that is spread to Equus caballuss and worlds by septic mosquitoes. Equine Encephalitis can do terrible complications in the cardinal nervous system and can sometimes ensue in decease. Equine Encephalitis occurs merely in a specific type of mosquito that feeds merely on birds. This is transmitted to Equus caballuss and worlds by mosquitoes that feed on both birds and other mammals. About half the people who get infected dice and the other half suffer terrible encephalon harm.

There are many control measures taken for the preventing of mosquito bites and tick bites. One of the most common ways of forestalling bites is by utilizing the chemical permethrin. This chemical is better known as DEET. This chemical has many positive effects. It is really dependable because it is inexpensive and can be sprayed over Fieldss with a low possibility of being earnestly harmed. However. it besides has some negative points. Permethrin is known to do shudders. incoordination. elevated organic structure temperature. and increased aggressive behaviour. Permethrin is besides toxic to many other beings such as Apis melliferas and fish. Another manner we could protect ourselves from these insects is by using insect repellants that do non incorporate DEET. This will non do any harmful side effects. but may be less effectual than using DEET.

After closely analyzing the positive and negative facets of ways to forestall bites. I am reasoning that it is more dependable to utilize DEET instead than another chemical. Even though DEET may do harmful side effects. it has ne’er been known to for good damage a individual. This makes the usage of DEET much more dependable.
