Blight leads to increase in disease-carrying mosquitoes

Louisiana State University researchers recently published findings that blight leads to an increased abundance of disease-carrying mosquitoes.

Risk models for West Nile Fever may predict areas of future outbreaks a year in advance

Knowing the environmental and human-related variables that characterize the favorable areas for the incidence of the West Nile virus, a flavivirus that is transmitted from birds to humans by mosquitoes, is essential to identify those places in Europe at high risk of experiencing outbreaks, even before these are registered, thus enabling preventive measures to be taken.

Neanderthal gene can confer protection against severe COVID-19, finds study

A new study has detailed how some of the genes in the human genome inherited from Neanderthals appear to confer a protective effect against severe COVID-19.

Evolution of the spike gene of SARS-CoV-2 for human adaptation

Researchers have found a 96% similarity in nucleotide sequence between bat coronavirus (RaTG13), isolated from Rhinolophus affinis bats in China in 2013, and SARS-CoV-2 and ~97% amino acid similarity with the Spike (S) protein. This S protein performs two essential roles, i.e., mediates receptor-binding and membrane fusion. Hence, spike protein is regarded as a key coronavirus determinant of host tropism.

Predicting future mamalian hosts of SARS-CoV-2

Researchers at the Beijing Computational Science Research Center and Peking University analyzed sequences of the angiotensin-converting enzyme 2 (ACE2) proteins from 16 mammals and predicted the structures of ACE2- receptor-binding domain (RBD) complexes.

No inflammation of cerebrospinal fluid in COVID-19 patients with neurological features, study finds

Many patients with COVID-19 have shown neurological complications, leading to scientific interest in the role played by its causative pathogen, SARS-CoV-2, in brain inflammation. A new study has described the absence of neuroinflammation in cerebrospinal fluid (CSF).

West Nile virus-infected mosquitoes are abundant in lower-income areas of Baltimore

In a new study published in the Journal of Medical Entomology, researchers at the University of Maryland (UMD) found higher rates of West Nile virus-infected mosquitoes in lower-income neighborhoods in urban areas of Baltimore, Maryland.

Higher risk of West Nile virus infection in low-income urban neighborhoods in Baltimore

In Baltimore, Maryland, people living in low-income urban neighborhoods are more at risk of contracting West Nile virus, a mosquito-borne disease, than people living in more affluent neighborhoods. So reports a new study published in the Journal of Medical Entomology.

Virginia Tech researchers awarded NIH grant to develop Zika virus vaccine

Flaviviruses -- a group of viruses transmitted by ticks or mosquitoes -- infect an estimated 400 million people annually with diseases like yellow fever, Dengue fever, West Nile virus, and, most recently, Zika virus.

Invasive alien species threaten biological diversity, shows study

The raccoon, raccoon dog, mink, and golden jackal are not native to Germany or Europe but are increasingly spreading in these non-native regions.

Lung biomarkers may predict severe COVID-19

Two University of New Mexico researchers postulate certain specific biomarkers' relevance in predicting the potential for progression to severe COVID-19 in a paper published on the preprint server bioRxiv*

Parkinson's disease diagnosed after SARS-CoV-2

As the COVID-19 pandemic continues to spread, new and unusual chronic sequelae of the disease are cropping up in many medical practices. Now, a new case paper published in The Lancet in September 2020 describes a case of new-onset Parkinson's disease following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Climate change could shift the spread of West Nile virus

West Nile virus spreads most efficiently in the US at temperatures between 24-25 degrees Celsius (75.2-77 degrees Fahrenheit), a new study published today in eLife shows.

15 Sep 2020

Exponential rise in COVID-19 hospitalization risk with age due to waning T cell immunity

The age-related increase in the risk of severe disease and death from COVID-19 mirrors earlier patterns seen with infections. Such trends may help understand the mechanisms underlying the clinical feature. A recent study published in the preprint server medRxiv* in August 2020 shows the effect of age and sex on COVID-19 hospitalization rates in the USA and helps understand how immune function is involved in this pandemic.

Researchers explore social behavior of animals toward emerging infectious diseases

Humans are not the only social animal struggling with new infectious diseases. When Hamilton College Associate Professor of Biology Andrea Townsend began studying the social behavior of American crows, her work was complicated by West Nile virus, an emerging disease with devastating effects on crow populations.

Natural compund in cedar and grapefruit skin could help repel mosquitoes and ticks says CDC

Over the last few years, there has been a rise in the number of cases of diseases caused by mosquito and tick bites. The U.S. Centers for Disease Control and Prevention (CDC) has said that a natural chemical compound could help combat this problem. This compound Nootkatone is found commonly in cedar trees, and grapefruit skin says the organization.

Humans promote diseases from the animal kingdom

The coronavirus pandemic, which has now infected nearly 19 million and killed more than 712,000 people, most likely originated from bats. Just like other coronavirus outbreaks in the past, a spill-over event or zoonosis caused the viruses to jump from animals to humans.

CDC warns acute flaccid myelitis is poised for a comeback in kids this fall

As if the novel coronavirus pandemic was not enough! Now the United States Centre for Disease Control and Prevention (CDC) warns parents and pediatricians to be on the watch for a rare condition called Acute Flaccid Myelitis or AFM for short, which could affect young children and cause unexplained muscle paralysis similar to poliomyelitis. Their report is published today in the Morbidity and Mortality Weekly Report.

Warming climate in Southern California may increase risk of West Nile outbreaks

As climate change brings hotter weather to Southern California, coastal populations from San Diego to Santa Barbara may face an increased risk of contracting West Nile virus and other mosquito-borne diseases, suggests a new study led by researchers at the University of California, Berkeley.
