Mosquitos cause more human suffering than any other organism — over one million people worldwide die from mosquito-borne diseases every year. Not only can mosquitos carry diseases that afflict humans, they also transmit several diseases and parasites that dogs and horses are very susceptible to. These include dog heartworm, West Nile virus (WNV) and Eastern equine encephalitis (EEE). In addition, mosquito bites can cause severe skin irritation through an allergic reaction to the mosquito’s saliva – this is what causes the red bump and itching. Mosquito vectored diseases include protozoan diseases, i.e., malaria, filarial diseases such as dog heartworm, and viruses such as dengue, encephalitis and yellow fever. CDC Travelers’ Health provides information on travel to destinations where human-borne diseases might be a problem.
Ticks are transmitters (vectors) of diseases for humans and animals. Tick bites spread illnesses like Lyme disease and Rocky Mountain spotted fever. Symptoms of tick borne diseases can include bull's eye rashes, fatigue, fevers, headaches, stiff necks, muscle and/or joint pains, and dizziness. Lyme disease, is carried in a large percent of deer ticks in New Jersey, this is the most feared tick borne ailment of all. It can cause severe, permanent neurological problems in some victims.
