anyone know if mosquitos are helping to spread ebola?
I haven't heard anything about this angle but it seems like they would be a perfect vector of transmission. Ideas? |

I found this reference although its not clear. I do think if one bit someone with Ebola then someone else squished it they would be exposed to the virus.
http://www.who.int/ith/diseases/haemorrhagicfevers/en/ Haemorrhagic fevers Haemorrhagic fevers are viral infections; important examples are Ebola and Marburg haemorrhagic fevers, Crimean–Congo haemorrhagic fever (CCHF), Rift Valley fever (RVF), Lassa fever, Hantavirus diseases, dengue and yellow fever. Hantavirus diseases, dengue and yellow fever are described separately. Cause Viruses belonging to several families. Ebola and Marburg belong to the Filoviridae family; hantaviruses, CCHF and RVF belong to the Bunyaviridae family; Lassa fever virus belongs to the Arenaviridae family; and dengue and yellow fever belong to the Flaviviridae family. Transmission Viruses that cause haemorrhagic fevers are transmitted by mosquitoes (dengue, yellow fever, RVF), ticks (CCHF), rodents (Hantavirus, Lassa) or bats (Ebola, Marburg). For Ebola and Marburg viruses, humans have been infected from contact with tissues of diseased non-human primates (monkeys and apes) and other mammals, but most human infections have resulted from direct contact with the body fluids or secretions of infected patients. Humans who develop CCHF usually become infected from a tick bite but can also acquire the virus from direct contact with blood or other infected issues from livestock or from infected patients. RVF can be acquired either by mosquito bite or by direct contact with blood or tissues of infected animals (mainly sheep), including consumption of unpasteurized milk. Lassa fever virus is carried by rodents and transmitted by excreta, either as aerosols or by direct contact. Some viral haemorrhagic fevers have been amplified in hospitals by nosocomial transmission resulting from unsafe procedures, use of contaminated medical devices (including needles and syringes) and unprotected exposure to contaminated body fluids. Nature of the disease The haemorrhagic fevers are severe acute viral infections, usually with sudden onset of fever, malaise, headache and myalgia followed by pharyngitis, vomiting, diarrhoea, skin rash and haemorrhagic manifestations. The outcome is fatal in a high proportion of cases (more than 50%). Geographical distribution Diseases in this group occur widely in tropical and subtropical regions. Ebola and Marburg haemorrhagic fevers and Lassa fever occur in parts of sub-Saharan Africa. CCHF occurs in the steppe regions of central Asia and in central Europe, as well as in tropical and southern Africa. RVF occurs in Africa and has recently spread to Saudi Arabia and Yemen. (Maps can be found on WHO website.) Risk for travellers Very low for most travellers. However, travellers visiting rural or forest areas in countries or areas at risk may be exposed to infection. Prophylaxis None (except for yellow fever). Precautions Avoid exposure to mosquitoes and ticks and contact with rodents, non-human primates or bats. Avoid unpasteurized milk |

However, a fly could transmit Ebola.
http://www.orkin.com/flies/house-fly/house-fly-and-disease/ House Flies and Disease House flies are recognized as carriers of easily communicable diseases. Flies collect pathogens on their legs and mouths when females lay eggs on decomposing organic matter such as feces, garbage and animal corpses. House flies carry diseases on their legs and the small hairs that cover their bodies. It takes only a matter of seconds for them to transfer these pathogens to food or touched surfaces. Mature house flies also use saliva to liquefy solid food before feeding on it. During this process, they transfer the pathogens first collected by landing on offal. Diseases carried by house flies include typhoid, cholera and dysentery. Other diseases carried by house flies include salmonella, anthrax and tuberculosis. House flies have also been known to transmit the eggs of parasitic worms. |

eeeww! Didn't know about the flies! I was thinking that the mosquitoes could transmit virus by biting an infected person and then biting someone else and transmitting it that way not just having someone swat it and get the blood on their skin.
ie a family member could infect everyone in the house via a mosquito. |

Houseflies: That is a form of air-borne I can believe in. That goes with plane-borne and bat-borne.
Who needs aerosols when there are so many fast efficient horses to ride? |
