Additionally, a whole host of novel technologies are under current development for mosquito control and the World Health Organization has recently lent its support for the accelerated development of modern methods for mosquito control such as the use of Wolbachia bacteria to render mosquitoes resistant to the virus, and, the release of sterilized male mosquitoes that breed with wild female mosquitoes to give rise to non-viable offspring (offspring that do not survive to the biting, adult stage).Oxitec’s genetically modified OX513A mosquito was approved by Brazils National Biosecurity Technical Commission (CTNBio) in April 2014 and it was being used to try to combat mosquitoes carrying the Zika virus in the town of Piracicaba, São Paulo in 2016.In the 1940s and 1950s, the Aedes aegypti mosquito was eradicated on some Caribbean islands and in at least eighteen Latin American countries. Decreasing political will and presumably available money, mosquito resistance to insecticide, and a pace of urbanization which exceeded eradication efforts led to this mosquitos comeback. Treatment
There is currently no specific treatment for Zika virus infection. Care is supportive with treatment of pain, fever, and itching. Some authorities have recommended against using aspirin and other NSAIDs as these have been associated with hemorrhagic syndrome when used for other flaviviruses. Additionally, aspirin use is generally avoided in children when possible due to the risk of Reye syndrome.Zika virus had been relatively little studied until the major outbreak in 2015, and no specific antiviral treatments are available as yet.
Punctate epithelial erosions are a pathology affecting the cornea. Signs and symptoms
It is a characterized by a breakdown or damage of the epithelium of the cornea in a pinpoint pattern, which can be seen with examination with a slit-lamp. Patients may present with non-specific symptoms such as red eye, tearing, foreign body sensation, photophobia and burning. Cause
Punctate epithelial erosions may be seen with different disorders:

Rosacea
Dry-eye syndrome
Blepharitis
Acute bacterial conjunctivitis
Trauma
Exposure keratopathy from poor eyelide closure
Ultraviolet or chemical burn
Contact lens-related disorder such as toxicity or tight lens syndrome
Trichiasis
Entropion or ectropion
Floppy eyelid syndrome
Chemotherapy i.e. cytosine arabinoside
Thygesons Superficial Punctate Keratopathy

Diagnosis
Slit lamp examination

Treatment
Due to the different underlying causes, proper diagnosis, treatment, and prognosis can only be determined by an eye care professional. Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment. Patients should discontinue contact lens wear until recovery. == References ==
