Innovative smallpox vaccine research study to be conducted at Case Medical Center

...been vaccinated against smallpox. Smallpox is a contagious and sometimes fatal infectious disease characterized by raised bumps that appear on the face and body of an infected person. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The World Health Organization de...

WHO data confirms low level of resistance to Tamiflu

...y influenza A and B viruses. Influenza is a highly contagious viral illness and is characterised by a sudden onset of debilitating clinical symptoms which affect the entire body. Up to 500 million people are infected by influenza and up to 500,000 deaths are attributed to influenza each year. Influenza complic...

Herpes infection may be symbiotic, help beat back some bacteria

...sed vaccination to eliminate the deadly and highly contagious smallpox virus. Vaccines are currently in use or in clinical trials for several disease-causing strains of herpes. Human herpes viruses include oral and genital herpes, the chickenpox virus, cytomegalovirus, Epstein-Barr virus and Kaposi's sarcoma...

Leeches ferry infection among newts

...chers point out that Ichthyophonus might not be as contagious as other leech-transmitted amphibian parasites. That is because this particular parasite lodges itself in muscle tissue instead of blood. A leech would have to be feeding right on top of a newt's infected muscle in order to transmit the infection. Ho...

Antifungal drug kills TB bug

...vide the answer. Tuberculosis, or TB, is a highly contagious disease of the lungs that was thought to have been virtually eliminated by the 1960s, but is now resurgent and kills nearly two million people worldwide every year. New infections are occurring at a rate of one per second. Of equal concern is the ...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...d of seven to 17 days, during which people are not contagious and feel fine. The first symptoms emerge during what is called the prodrome phase, and they include head and body aches, fatigue, a high fever and, sometimes, vomiting. This phase lasts two to four days and at this point people may or may not be cont...

Experimental vaccine protects mice against deadly 1918 flu virus

... specialized biosafety labs where scientists study contagious and potentially deadly materials under high-level safety and contamination precautions designed to protect the researchers and prevent microorganisms from entering the environment. "Understanding why this influenza virus was so deadly is an extrem...

Researchers find 'secret weapon' used by SARS virus

In 2003, the highly contagious and often-deadly mystery disease now called SARS emerged explosively out of Southern China. It eventually killed an estimated 916 people in Asia, Europe, and North and South America--nearly one in ten of those it infected. When scientists identif...

Microscopic passengers to hitch ride on space shuttle

...able atmosphere, to help prevent contamination and contagious infection while in space. Scientists also believe this research some day may benefit people on Earth by leading to new therapies to treat infection. "This experiment requires only the minimum of space shuttle resources, but it has the potential to ...

How can we protect patients with weakened immune systems from influenza?

...se patients with compromised immune systems may be contagious longer than people with healthier immune systems, they may be a reservoir for the disease. In addition to the yearly toll of ordinary influenza (as many as 36,000 annual fatalities in the U.S.), added concerns over potential threats -- an avian flu p...

Avian influenza virus in mammals spreads beyond the site of infection to other organ systems

...tential for pandemic spread. This virus is highly contagious in birds and spreads easily due to the agricultural and migratory nature of the bird species infected, including poultry, water fowl, and other migratory species (See commentary by Brown for more information). While spread of avian influenza from bi...

Minor mutations in avian flu virus increase chances of human infection

...a virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. So far, its spread to humans has been limited, with 177 documented severe infections, and nearly 100 deaths in Indonesia, Vietnam, Thailand, Cambodia, China, Iraq, and Turkey as of March 14, 2006, according to the World...

Cell barrier shows why bird flu not so easily spread among humans

...influenza such as bird flu evolve to become highly contagious human pathogens. Most scientists agree a pandemic of avian influenza will occur at some time. The worst-case scenario would be a form of influenza similar to the strain of 1918 that killed between 30 million and 50 million people globally.The new wo...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...oncerns of a bioterror attack involving the highly contagious and fatal virus have prompted researchers to search for new smallpox vaccines and treatments. The currently licensed smallpox vaccine consists of a live but weakened strain of vaccinia virus, a relative of the variola virus that causes smallpox. Va...

Virologist finds contagious equine flu in dogs

...ornell University virologist has isolated a highly contagious equine flu virus that is spreading a sometimes-fatal respiratory flu among dogs, and is responsible for a major dog-flu outbreak in New York state. There is no evidence that the virus could infect people. According to a paper published in the Sept. ...

Aircraft Cabin Ventilation Influences The Transmission Of Diseases In-flight

...in is associated with sitting within two rows of a contagious passenger for a flight time of more than 8 hours. This is believed to be relevant to other airborne infectious diseases. However, in one outbreak of SARS, passengers as far as seven rows away from the source passenger were affected. The review state...
