Assalammualaikum, hye everyone.
Today, I want to share about Zika. I know it from my safety toolbox at the office.
How do people become infected?
Zika is transmitted to people through the bite of infected female mosquitoes, primarily the Aedes aegypti mosquito, the same type that spreads dengue, chikungunya and yellow fever. The Pan American Health Organization (PAHO) said Aedes mosquitoes are found in all countries in the Americas except Canada and continental Chile, and the virus will likely reach all countries and territories of the region where Aedes mosquitoes are found.
How do you treat Zika?
How do you treat Zika?
There is no treatment or vaccine for Zika infection. Companies and scientists are racing to develop a safe and effective vaccine for Zika, but the World Health Organization (WHO) had said early in 2016 that it would take at least 18 months to start large scale clinical trials of potential preventative shots. A vaccine is not expected to be ready for widespread use for at least two or three years. US government researchers said they started their first clinical trial of a Zika vaccine.
How dangerous is it?
How dangerous is it?
The US Centers for Disease Control and Prevention concluded that infection with the Zika virus in pregnant women is a cause of the birth defect microscopically and other severe brain abnormalities in babies. The CDC said now that the causal relationship has been established, several important questions must still be answered with studies that could take years. According to the World Health Organization, there is strong scientific consensus that Zika can cause the birth defect microscopically in babies, a condition defined by unusually small heads that can result in developmental problems. In addition, the agency said it could cause Guillain Barre syndrome, a rare neurological disorder that can result in paralysis. Conclusive proof of the damage caused by Zika may take months or years. Brazil reports the number of confirmed cases of microscopically at 1,835 as doctors and Brazilian health officials find that some suspected cases of microscopically are not the disorder. Suspected ones under investigation had declined to 3,257. Brazil registered 91,387 likely cases of the Zika virus from February until April 2. Current research in Brazil indicates the greatest microscopically risk is associated with infection during the first trimester of pregnancy, but health officials have warned an impact could be seen in later weeks. Recent studies have shown evidence of Zika in amniotic fluid, placenta and fetal brain tissue.
What are the symptoms of Zika infection?
People infected with Zika may have a mild fever, skin rash, conjunctivitis, muscle and joint pain and fatigue that can last for two to seven days. But as many as 80 percent of people infected never develop symptoms. The symptoms are similar to those of dengue or chikungunya, which are transmitted by the same type of mosquito.
How can Zika be contained?
How can Zika be contained?
Efforts to control the spread of the virus focus on eliminating mosquito breeding sites and taking precautions against mosquito bites such as using insect repellent and mosquito nets. US and international health officials have advised pregnant women to avoid travel to Latin American and Caribbean countries where they may be exposed to Zika.
What is the history of the Zika virus?
The Zika virus is found in tropical locales with large mosquito populations. Outbreaks of Zika have been recorded in Africa, the Americas, Southern Asia and the Western Pacific. The virus was first identified in Uganda in 1947 in rhesus monkeys and was first identified in people in 1952 in Uganda and Tanzania, according to the WHO.
Can Zika be transmitted through sexual contact?
Can Zika be transmitted through sexual contact?
The World Health Organization (WHO) said sexual transmission is “relatively common” and has advised pregnant women not to travel to areas with ongoing outbreaks of Zika virus. It also advised women living in areas where the virus is being transmitted to delay getting pregnant. The US CDC is investigating several cases of possible sexual transmission. Those cases involved possible transmission of the virus from men to their sex partners. The CDC issued updated recommendations for preventing and testing for Zika infection on July 25, warning that the virus can be transmitted through unprotected sex with an infected female partner. A reported case of female to male sexual transmission in New York City, and limited human and non human primate data indicating that Zika virus RNA can be detected in vaginal secretions, led to the new warning, the agency said. CDC’s expanded warnings on sexual exposure to Zika cautioned against sex without a condom or other barrier method of protection with any person, male or female, who has traveled to or lives in an area with Zika, including female to female transmission with a pregnant partner. New Zika research released on Aug. 25 found that the virus may spread sexually from a man to a woman even if the man had no symptoms of Zika infection, which could trigger new guidelines from the CDC. British health officials reported Zika was found in a man’s semen two months after he was infected, suggesting the virus may linger in semen long after infection symptoms fade. The PAHO said Zika can be transmitted through blood, but this is an infrequent transmission mechanism. There is no evidence Zika can be transmitted to babies through breast milk. The WHO has identified Zika cases in Argentina, Chile, France, Italy and New Zealand as likely caused by sexual transmission.
What other complications are associated with Zika?
What other complications are associated with Zika?
Zika has also been associated with other neurological disorders, including serious brain and spinal cord infections. The long term health consequences of Zika infection are unclear. Other uncertainties surround the incubation period of the virus and how Zika interacts with other viruses that are transmitted by mosquitoes, such as dengue.
I hope you all can get benefit from the issues that I shared.
Thank you. See you again.
