Researchers have found associations between Zika and Meningoencephalitis as well as Myelitis. The first known isolation of Zika virus in saliva from an Italian patient raises concerns about the potential risk of human-to-human transmission through saliva. A new experimental Zika drug developed by BioCryst Pharmaceuticals and tested on mice have generated positive results.
The Aedes aegpti in Puerto Rico and Mexico have developed resistance to permethrin, and the insecticide is likely going to lose its effectiveness in places where it has been used as the main insecticide for years. The latest total of microcephaly cases in Brazil is 745. A timeline that charts Zika virus’ origin and subsequent spread from its discovery nearly 70 years ago has been published.

Zika-Meningoencephalitis association

French researchers reported findings on a Zika virus link to meningoencephalitis in an 81-year-old man. The elderly was admitted to an intensive care unit (ICU) 10 days after returning from a 4-week cruise to New Caledonia, Vanuatu, the Solomon Islands, and New Zealand. Magnetic resonance imaging (MRI) of the patient’s brain as well as findings on analysis of cerebrospinal fluid (CSF) was suggestive of meningoencephalitis.
