Insects (mosquitoes, fleas, lice, bed bugs) and ticks can spread a variety of infectious diseases caused by viruses, bacteria, and parasites. Ticks come in a variety of species, each with its own unique environment. Lyme disease, the tick-borne spotted fevers, tick-borne meningoencephalitis, etc. The prevalence of the diseases reported previously is constantly shifting. The most prevalent diseases will be briefly discussed.
Malaria is the most serious health threat for travelers due to its widespread distribution in tropical and subtropical regions around the world and its potentially lethal result. A single celled urine parasite of the genus Plasmodium causes the disease, which is spread by mosquitoes of the genus Anopheles. There are a variety of plants.
A Flavivirus causes Dengue Fever, which is an infectious illness. It is experiencing a quick comeback. It is spread by the bite of mosquitoes of the genus Aedes, which breeds in stagnant water near people’s homes. It has an endemic-epidemic pattern of transmission. The disorder has four different serotypes.
Yellow fever is an infectious haemorrhagic fever induced by the yellow fever virus, which is caused by a Flavivirus. The disease is spread by the bite of an Aedes mosquito. The virus’s natural host is a specific species of monkey found in forest areas. The virus will inadvertently spread to human populations.
The Trypanosoma protozoa (single celled blood-dwelling parasites) that inflict human African typanosomiasis, also known as sleeping sickness, is a parasitic disease caused by many distinct species of Trypanosoma protozoa. It is spread by the bite of a fly known as the Glossina or Tsetse fly. It can only be found in Africa. The illness is often lethal if it is not treated.
Lyme disease is an infection triggered by Borrelia burgdorferi, a bacterium from the Borrelia genus that is transmitted through the bite of a tick called Ixodes. Borrelia bacteria is carried by 10 -15% of them. Depending on the field, the risk of being infected by a tick bite ranges from 1% to 6%.
A Flavivirus causes tick-borne meningoencephalitis, a nervous system disease. It is spread by the bite of an Ixode tick in the spring and summer. The disease is only found in a few places in the affected areas. Over the last few years, it has been steadily growing. Alsace is infected with the disease.
