West Nile Virus
West Nile virus is a potentially serious illness. Experts believe it is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall. About one in 150 people infected with West Nile virus will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent. Up to 20% of the people who become infected have symptoms such as fever, headache, body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. Symptoms can last for as short as a few days, though even healthy people have become sick for several weeks. Approximately 80% of people who are infected with West Nile virus will not show any symptoms at all.
West Nile Virus
West Nile virus Encephalitis is a mosquito-borne viral disease, which can cause an inflammation of the brain and can be a serious, even fatal, illness.
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).
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.
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.
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.
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.
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.
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.
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.
The U.S. public health system has been starved for decades and lacks the resources necessary to confront the worst health crisis in a century. Read the investigation from KHN and The Associated Press.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is currently at the heart of a pandemic that has cost the world more than 550,000 lives, 12 million infections, and uncounted years of productivity, is an RNA virus with the largest genome among all such viruses. This 30 kb size virus has caused many difficulties for scientists in search of a vaccine.
Sanford Burnham Prebys Medical Discovery Institute today announced a research agreement with Eli Lilly and Company (Lilly) to characterize Lilly's next-generation anti-SARS-CoV-2 antibodies.
Scientists at two Northern Arizona University research centers--the Pathogen and Microbiome Institute and the Center for Health Equity Research--recently received grants totaling $175,000 from the Flinn Foundation in support of projects directed at responding to the COVID-19 threat.
Every year, more than 68,000 people end up with a clinical case of Japanese encephalitis. One in four of these patients will die. The mosquito-borne virus, which is most common in Southeast Asia, also causes severe neurological damage and psychiatric disorders.
Parkinson's disease (PD) is expected to reach over 14 million cases worldwide by 2040. As longevity increases, so does the number of persons living with PD.
The University of Alabama at Birmingham will join an international effort coordinated by Scripps Research to test drugs for COVID-19.
A 4-year-old girl was rushed to the emergency room three times in one week for asthma attacks.
From the plagues of medieval Europe to the influenza pandemic of 1918, the specter of the next public health disaster has gripped the minds of scientists, captivated the imaginations of writers and vexed conspiracy theorists.
A viewpoint published in the journal JAMA February 28, 2020, discusses how a low-carbon future could improve global health and provide economic benefit.
New research from UC Riverside shows scientists may soon be able to prevent disease-spreading mosquitoes from maturing. Using the same gene-altering techniques, they may also be able help boost reproduction in beneficial bumblebees.
In an invited Commentary just published in JAMA Internal Medicine, Columbia Mailman School of Public Health professors Drs. Steven Stellman and Jeanne Mager Stellman offer their perspective on results from a recent study on Pyrethroid, among the most widely used insecticides in the world for public health control of vector-borne illnesses, including West Nile virus.
