could you get HIV from mosquito bite- am worried of this??
From the very start of the HIV epidemic, there have been issues about the transmission of HIV thru biting and bloodsucking insects, which include mosquitoes. It turned into a herbal challenge given that many illnesses, consisting of malaria and Zika fever, are comfortably transmitted via insect bite.
but, this isn't the case with HIV. Epidemiological studies carried out by the facilities for disorder control and infection in Atlanta have proven no evidence of HIV transmission thru mosquitoes or every other bugs, even in international locations with extraordinarily high fees of HIV and uncontrolled mosquito infestations.
the lack of such outbreaks supports the conclusion that HIV can not be transmitted by way of the insects.
From a biological perspective, mosquito
bites do not result in the blood-to-blood transmission (which might be considered the route of infection for a bloodborne virus like HIV). rather, the insect injects saliva and anticoagulants which permit the mosquito to feed more efficiently. As such, blood itself isn't injected from person to person, and that's vital for some of reasons.
whilst diseases such as yellow fever and malaria are readily transmitted via the salivary secretions of certain species of mosquitoes, HIV does not have the ability to reproduce or thrive in insects since there are no host cells (such as T-cells), which the virus needs to enable replication. instead, the virus is digested within the mosquito's intestine along with the blood cells on which the insect feeds.
even if HIV were ale to survive for a short period of time, the minute quantity of virus that a mosquito might convey would make transmission always impossible. in order to ensure viability, it would take around 10 million mosquitoes to accrue sufficient virus to enable transmission.
bottom line, HIV transmission can only arise under four specific conditions.
If any of these conditions are not satisfied, the likelihood of infection is considered negligible to nil:
There must be a body fluid (blood, semen or breast milk) in which HIV can thrive. It cannot thrive in saliva, urine, sweat or feces.
There must be a route by which the virus can readily enter the body, either through vulnerable mucosal tissues or direct blood-to-blood transmission.
There must be ample quantity of HIV to effect infection. We know, for example, that the lower a person's viral load, the lower the risk of infection.
Under these conditions, HIV transmission through mosquito bites in considered impossible.
Types of Mosquito-Borne Diseases
While mosquitoes pose no threat of HIV transmission, there are other types of diseases associated with mosquito bites. Among them:
Eastern equine encephalitis
La Crosse encephalitis
St. Louis encephalitis
West Nile virus
Mosquitoes are known to carry many classes of infectious diseases, including viruses and parasites.
Mosquitoes are estimated to transmit disease to more than 700 million people each yer, resulting in millions of resulting deaths.
These disease outbreaks are most commonly seen in Africa, Asia, Central America and South America, where disease prevalence, temperate climates and lack of mosquito control provide greater opportunity for he spread of mosquito-borne diseases.
