“If you really want a zero per cent risk of having a complication from Zika virus, the only way to do that is to not go (to a Zika-affected country),” advises Dr. Isaac Bogoch, infectious disease specialist at Toronto General Hospital.

Zika virus and the Olympics

Daily Mail  online


Dr. Isaac Bogoch, an infectious diseases specialist at Toronto General Hospital who has studied the anticipated path of the virus, said while it is 'very likely' the Olympics could speed up the spread of Zika around the world, most people wouldn't be affected.

'The spread of Zika to other countries is already happening,' he said. 'Canceling the Olympics is not going to prevent that.'

'I'm still going': Olympian Sarah Walker commits to Rio despite Zika fears

"It is the flawless set-up for proliferation", said Isaac Bogoch, a tropical infectious disease specialist at Toronto General Hospital, who published a scientific paper predicting Zika's rapid spread.

In Brazil, where the virus is believed to have arrived in the hemisphere before spreading via mosquitoes, it has been linked to a brain defect in almost 4 000 newborns. There has also been an increase in reported cases of Guillain-Barre muscle weakness syndrome...

Rapid spread of Zika virus in the Americas raises alarm

Science News  online


In the United States, that could leave millions of people at risk for infection, Isaac Bogoch and colleagues reported January 14 in the Lancet. Bogoch’s team made a global map of places Zika virus could readily spread. The researchers factored in climate, flight patterns out of Brazil, and mosquito species that can carry Zika virus, Aedes aegypti and Aedes albopictus. (Both species hug the U.S. Gulf Coast, and A. albopictus fans out across the southeast and up along the coast, ranging as far north as Connecticut.)

As many as 60 percent of U.S. residents live in areas threatened by Zika virus (at least during warm seasons), the team found. For southern states, especially, “there’s a potential for ongoing transmission,” says Bogoch, a tropical infectious diseases physician at Toronto General Hospital...

Zika Warning Spotlights Latin America’s Fight Against Mosquito-Borne Diseases

The New York Times  online


Dr. Isaac I. Bogoch, a tropical infectious disease specialist at the University of Toronto who is part of a team modeling the potential for Zika to spread, warned that the Olympics could serve as a catalyst for the virus, which some researchers believe may have arrived in Brazil during another sports mega-event, the 2014 World Cup.

“There will be people traveling to Brazil from all over the world,” Dr. Bogoch said in an email.

“The concern is that infected individuals will travel back to their home country and introduce the virus to new regions.”

Dr. Bogoch and other researchers determined that Zika had the potential to rapidly spread to other parts of the world, according to findings published last week in the British medical journal The Lancet...

Olympics in Brazil could spark spread of Zika virus abroad, Canadian docs warn

Global News  online


“People might go to Brazil, get the infection and bring it home to their home country and if they’re living in an area conducive for seasonal or year-round transmission, the infection will be present in a new area. We don’t even need to wait for the Olympics to happen, it’s happening now,” warned Dr. Isaac Bogoch, a tropical infectious disease specialist at Toronto General Hospital and the University of Toronto.

“[The Olympics] has the potential to amplify spread. It’s something we have to be aware of and certainly have an understanding of,” he told Global News...

Assessment of the potential for international dissemination of Ebola virus via commercial air travel during the 2014 west African outbreak PubMed


The WHO declared the 2014 west African Ebola epidemic a public health emergency of international concern in view of its potential for further international spread. Decision makers worldwide are in need of empirical data to inform and implement emergency response measures. Our aim was to assess the potential for Ebola virus to spread across international borders via commercial air travel and assess the relative efficiency of exit versus entry screening of travellers at commercial airports.

Comparison of community-wide, integrated mass drug administration strategies for schistosomiasis and soil-transmitted helminthiasis: a cost-effectiveness modelling study PubMed


More than 1·5 billion people are affected by schistosomiasis or soil-transmitted helminthiasis. WHO's recommendations for mass drug administration (MDA) against these parasitic infections emphasise treatment of school-aged children, using separate treatment guidelines for these two helminthiases groups. We aimed to evaluate the cost-effectiveness of expanding integrated MDA to the entire community in four settings in Côte d'Ivoire.

Patient attrition between the emergency department and clinic among individuals presenting for HIV nonoccupational postexposure prophylaxis PubMed


Nonoccupational postexposure prophylaxis (nPEP) is recommended after a sexual or parenteral exposure to human immunodeficiency virus (HIV). Patients frequently seek care in an emergency department (ED) after an exposure and are usually referred to an HIV clinic for further management. There have been few data on determinants of attrition after presentation to EDs for nPEP.

Mapping the zoonotic niche of Ebola virus disease in Africa Elife


Ebola virus disease (EVD) is a complex zoonosis that is highly virulent in humans. The largest recorded outbreak of EVD is ongoing in West Africa, outside of its previously reported and predicted niche. We assembled location data on all recorded zoonotic transmission to humans and Ebola virus infection in bats and primates (1976–2014). Using species distribution models, these occurrence data were paired with environmental covariates to predict a zoonotic transmission niche covering 22 countries across Central ...

Mobile phone microscopy has a sensitivity of 69.4% for detecting any helminth egg and sensitivities of 81.0%, 54.4%, and 14.3% for the diagnosis of Ascaris lumbricoides, Trichuris trichiura and hookworm respectively.

Delirium in the postoperative cardiac patient: a review Journal of Cardiac Surgery


Background and aim of review: Cardiac surgery is increasingly common and relatively safe, but there are frequent reports of neuropsychiatric sequelae occurring in the postoperative period. One of the most common neuropsychiatric presentations of cardiac surgery is delirium, also called postcardiotomy delirium (PCD). Despite the vast numbers of cardiac surgeries performed today, there is a paucity of data on risk factors and management options of PCD available to the clinician. This review aims to summarize ...

This study examines perceptions of rock concert attendees about risk of noise-induced hearing loss (NIHL) and use of hearing protection at a busy Toronto rock concert venue. Methods: Two hundred and four questionnaires were completed and returned (75% response rate) by attendees at four rock concerts. Results: The respondents had an average age of 20.6 years and 55.4% were male. Thirty-four point three percent (34.3%) thought that it was somewhat likely and 39.8% thought it was very likely that noise levels at music ...

Efficacy and side effects of praziquantel against Schistosoma mansoni in a community of western Côte d'Ivoire Transactions of the Royal Society of Tropical Medicine and Hygiene


Praziquantel is efficacious against the adult stages of all human schistosome parasites, and has become the drug of choice for morbidity control of schistosomiasis. There is concern that resistance to praziquantel might develop or already exists, and could be further facilitated through new control initiatives relying on large-scale administration of praziquantel. Therefore, monitoring praziquantel efficacy in different epidemiological settings is required. We assessed the efficacy and side effects of praziquantel against ...

Enhanced epileptogenesis in S100B knockout mice Molecular Brain Research


S100B is a small calcium-and zinc-binding protein expressed by astrocytes in the central nervous system. Here, we examined the role of S100B in epileptogenesis using an amygdala kindling paradigm comparing S100B knockout mice with their wild-type counterparts. Astrocyte activation following kindling, assessed by glial fibrillary acidic protein expression in the hippocampus and amygdala, was similar in wild-type and knockout mice. In addition, wild-type and knockout mice did not have substantially different afterdischarge ...
