Home News Health Daily news 8 January 2019 THOUSANDS of Zika virus cases went unreported in Cuba in 2017, according to an analysis of data on travellers to the Caribbean island. Veiling them may have led to many other cases that year. The analysis suggests that Zika infections peaked in Cuba in the second half of 2017, at a time when the virus was waning in mainland North and South America. Cuban authorities didn’t follow the agreed practice of notifying the Pan American Health Organization (PAHO) of the outbreak. Cuba’s first case of Zika occurred in March 2016. A PAHO report says the country stopped providing updates on Zika in January 2017. In press reports in May 2017, Cuba said that nearly 1900 infections had been detected up to that point. But Nathan Grubaugh at the Yale School of Public Health and his colleagues estimate that the total cases in 2017 alone would have been more than double that at 5700. … [Read more...] about Exclusive: Cuba failed to report thousands of Zika virus cases in 2017
Zika virus epidemic
Researchers have generated six Zika virus antibodies that could be used to test for and possibly treat a mosquito-borne disease that has infected more than 1.5 million people worldwide. The antibodies "may have the dual utility as diagnostics capable of recognizing Zika virus subtypes and may be further developed to treat Zika virus infection," corresponding author Ravi Durvasula, MD, and colleagues report in a study published in the journal PLOS ONE. Dr. Durvasula is professor and chair of the department of medicine of Loyola Medicine and Loyola University Chicago Stritch School of Medicine. First author is Adinarayana Kunamneni, PhD, a research assistant professor in Loyola's department of medicine. Zika is spread mainly by mosquitos. Most infected people experience no symptoms or mild symptoms such as a rash, mild fever and red eyes. But infection during pregnancy can cause miscarriages, stillbirths and severe birth defects such as microcephaly. Zika virus is a textbook example … [Read more...] about Researchers Produce Six Antibodies to Combat Zika Virus
By Jon CohenOct. 31, 2018 , 11:55 AM When the Zika virus exploded in the Americas in 2015, it quickly became an international scare: Pregnant women, bitten by infected mosquitoes, could pass the virus to their babies, some of whom suffered brain malformations as a result. But the epidemic eventually wound down, thanks in part to large swaths of populations developing immunity. Now, scientists in Brazil have discovered that more than a third of the wild monkeys they tested for Zika have been infected, the strongest evidence yet that a “reservoir” for the disease outside of humans has the potential to form. “We found this phenomenon in two different cities at the same time, so [infected monkeys] are more common than we think,” says Maurício Lacerda Nogueria, a virologist at the São José do Rio Preto School of Medicine in Brazil, who led the new study. Even though his team is still a long way from showing that the monkeys spread the virus between … [Read more...] about Are wild monkeys becoming a reservoir for Zika virus in the Americas?
The atmosphere inside the laboratory on the outskirts of Vienna is literally buzzing with armies of male mosquitoes locked up inside net-covered boxes. Their sole mission in life: stop females from breeding. Better known for keeping a close watch on countries' nuclear activities, the International Atomic Energy Agency (IAEA) has joined the fight against Aedes aegypti -- the notorious mosquito responsible for spreading dengue, chikungunya and now the Zika virus. Experts from around the globe have been working strenuously in the IAEA's tightly-secured research facility in Seibersdorf, 30 kilometres (18 miles) south of the Austrian capital, to perfect something called the sterile insect technique, or SIT. The clue's in the name: male mosquitoes have their private parts zapped with a radioactive source before being released into nature to mate with wild females, which, as a result, will lay infertile eggs. The aim is to gradually reduce, if … [Read more...] about IAEA boffins seek to end Zika menace
Researchers at New York University College of Dentistry (NYU Dentistry), in collaboration with Rheonix, Inc. (Ithaca, NY), are developing a novel test for Zika virus that uses saliva to identify diagnostic markers of the virus in a fraction of the time of current commercial tests. The test, which was adapted from an existing model developed by NYU and Rheonix for rapid HIV testing, is described in two new publications appearing in PLOS ONE and the Journal of Visualized Experiments (JoVE). How Zika is Tested Outbreaks of infectious diseases are occurring with growing frequency thanks to factors such as population concentration and global air travel. A 2015 outbreak of Zika virus in Brazil spread to other countries in Central and South America, the Caribbean, and the Southern United States, leading the World Health Organization to declare Zika and its link to birth defects a public health emergency. "The recent Zika virus outbreak confirms that we need an effective surveillance and … [Read more...] about Researchers Adapt HIV Test in Developing Rapid Diagnostic Test for Zika Virus
