Undiagnosed acute HIV infection identified through RNA testing of pooled serum samples obtained during a dengue outbreak in São Paulo, Brazil

CONCLUSIONS: Promoting strategies to diagnose these individuals and provide them with medical treatment might be instrumental for controlling the HIV epidemic.

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

This study included more recent evidence compared to the previous one. The Bradford-Hill Viewpoints are used in public health to determine causation of diseases.11 Systematic application of the viewpoints can assist with analysing a possible causal relationship. Additional studies to assess the risk of microcephaly in affected pregnant mothers are ongoing.12 In this study we applied the Bradford-Hill viewpoints to investigate the association between Zika virus and Microcephaly. Method Using the Bradford Hills nine viewpoints we analysed data from a 2013 outbreak in French Polynesia and the 2015 Brazilian outbreak to esta...

BackgroundAn emerging infectious disease (EID) refers to a disease that has recently appeared in a population or one that has rapidly increased in incidence or geographic range. Examples of EIDs include Ebola, HIV/AIDS, hepatitis E and the vector‐borne diseases caused by Zika and dengue virus. EIDs pose a risk to transfusion safety, which can be direct, if the agent can be transmitted through blood transfusion, or indirect, where outbreaks reduce the pool of available donors. Although examples of both have been observed, the former will be the focus of this review. Many transfusion risks have become global due to globali...

Discussion We applied simple phenomenological models applied to surveillance data of Zika cases from Antioquia, Colombia, to forecast the size of the Zika epidemic and evaluate the reproduction number within the first two disease generations. Using the GRM model that incorporates the possibility of sub-exponential growth dynamics22, we were able to generate reasonable forecasts of epidemic size within 22% of observed values based on 30 days of epidemic data. By contrast, the logistic growth model consistently underestimated the epidemic size and was not able to capture the early growth phase of the Zika epidemic, which exh...

Associated with grave birth defects, the Zika virus tearing across Latin America could eventually affect more than half of the world's population. That's according to the London School of Hygiene &Tropical Medicine which agreed to an interview via email. Although the current epidemic in the Americas is being spread by the Aedes aegypti mosquito, according to Jimmy Whitworth, the School's Professor of International Public Health: "A number of mosquitos have been documented to carry the Zika virus. For example, the Aedes albopictus mosquito which resides in large parts of the U.S., southern Europe, and Asia is of...

Abstract: History provides us several illustrations where epidemic outbreaks have led to biological disasters. Accidental or deliberate release of harmful micro-organisms can also lead to biological disasters. With the advent of bio-terrorism, there is a growing realisation that biological agents can also be used as weapons of mass destruction. The spread of Spanish Influenza of 1917-18, the Human Immunodeficiency Virus (HIV) / Acquired Immuno Deficiency Syndrome (AIDS), Severe Acute Respiratory Syndrome (SARS), Swine Flu (H1N1), Avian Influenza (H5N1), Middle East Respiratory Syndrome (MERS), dengue, chikunguniya, Ebola o...

Among the arthropod-borne flaviviruses, the four dengue virus serotypes, dengue type 1 virus (DENV-1), dengue type 2 virus (DENV-2), dengue type 3 virus (DENV-3), and dengue type 4 virus (DENV-4) are most important in terms of human morbidity and geographic distribution. Dengue viruses cause dengue outbreaks and major epidemics in most tropical and subtropical areas whereAedes albopictus andAedes aegypti mosquitoes are abundant.A safe and effective vaccine against dengue is currently not available. Passive immunization with monoclonal antibodies from non-human primates or humans represents a possible alternative to vaccine...
