The pesticide used by the county, Pyrenone 25-5, is derived from chrysanthemums and is not the same insecticide that killed millions of honeybees last week after aerial sprayings in Florida and in SC.

The researchers infected a pigtail macaque with Zika when it was in the third trimester of pregnancy. The Zika virus used in the study was a 2010 Cambodian strain that is almost genetically identical to the strain now found in Brazil. The mother didn’t show any symptoms, such as fever, rash, or conjunctivitis. However, it didn’t take long for the scientists to see changes on the images they used to monitor the fetal brain.
“Patients who develop a fever are requested not to travel to other districts, to prevent the spread of disease”, Dr Wantanee said.
“We had not predicted that such a large area of the foetal brain would be damaged so quickly”. The researchers saw periventricular lesions in the occipital-parietal lobes.
In the macaque, the foetal brain stopped growing three weeks after infection, said the authors.
Rajagopal added that the speed of the damage hints that the strategy to prevent fetal brain injury may need to be a vaccine or a preventive medicine taken at the time of the mosquito bite.
Primates, including people, are an order of mammals that share many features of brain development.
This research revealed conclusively that the Zika virus had crossed from the mother through the placenta and into the fetal brain.
Italian researchers say they’ve found evidence Zika can affect the brains of adults, and may damage memory. In fact, 17 babies in the USA have been born with Zika-related birth defects, and there have been five pregnancy losses with Zika-related birth defects.
The U.S. Centers for Disease Control and Prevention concluded that infection with the Zika virus in pregnant women is a cause of the birth defect microcephaly, a condition defined by unusually small heads that can result in developmental problems, and other severe brain abnormalities in babies.
Twelve countries have reported sexual transmission.
Meanwhile, over the weekend and through today Singapore reported 29 more cases, putting its total since the end of August at 329. Its health ministry noted yesterday that it is monitoring eight pregnant women with Zika infections. The World Health Organization (WHO) said it is ready to extend support to the DOH especially in testing suspect Zika cases.
The Philippines reported its first case of Zika in 2012, that of a teenaged boy in Cebu island in the central Philippines.
The amount of virus inoculated in this study approximated what a person might contract from the probing and biting of an infected, feeding mosquito.
Several factors, now absent, would have to exist for Zika cases to affect the local population, Kelly said.
Ubial ordered the strict monitoring of pregnant women in Iloilo.

Atlantic County Public Health Officer Patricia Diamond said the resident is now doing well and is in recovery. The agency added that knowing the pregnancy status of people infected locally is not necessary information to protect public health. The long-term health consequences of Zika infection are unclear.
