Cases of severe and complicated malaria are almost always caused by infection with P. falciparum. The other species usually cause only febrile disease. [180] Severe and complicated malaria cases are medical emergencies since mortality rates are high (10% to 50%). [181] Recommended treatment for severe malaria is the intravenous use of ...
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
The result will cause that mosquito to ingest the parasite and allow it to transmit the Malaria disease into another person through the same mode of bite injection. [ 23 ] Flaviviridae viruses transmissible via vectors like mosquitoes include West Nile virus and yellow fever virus, which are single stranded, positive-sense RNA viruses enveloped ...
Found worldwide, it causes a so-called "benign malaria", not nearly as dangerous as that produced by P. falciparum or P. vivax. The signs include fevers that recur at approximately three-day intervals – a quartan fever or quartan malaria – longer than the two-day (tertian) intervals of the other malarial parasite.
Lyme disease; Plague; West Nile virus; Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people. [21] Humans can also be vectors for some diseases, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant. [citation needed]

The Plasmodium parasites that cause malaria are carried by female Anopheles mosquitoes. Lymphatic filariasis, the main cause of elephantiasis, is spread by a wide variety of mosquitoes. [102] A bacterial disease spread by Culex and Culiseta mosquitoes is tularemia. [103]
