BEIJING (Reuters) - China has reported a new outbreak of foot-and-mouth disease in cattle in the western province of Qinghai, but it has already been contained, a state newspaper said on Tuesday.

SHANGHAI (Reuters) - An outbreak of foot-and-mouth disease forced the killing of 91 cattle in northeastern China this week, the official Xinhua News Agency said. Foot-and-mouth disease causes severe weight loss in cloven-hoofed animals.
NEW YORK (Reuters Health) - A single course of hepatitis A and B vaccine is enough to protect most healthy travelers from contracting these infections, and current evidence suggests this protection is lifelong, a team of travel medicine experts concludes.
A new study examining whether patients with chronic Hepatitis C virus (HCV) were routinely vaccinated against Hepatitis A virus (HAV) found that vaccination rates were low, even though HAV vaccination is recommended for patients with chronic liver disease.
Poliovirus, the causative agent of poliomyelitis and a member of the family of Picornaviridae, is a human enterovirus. It is composed of an RNA genome that is a single-stranded positive-sense RNA. It was first isolate in 1909 and was published in 1981. It is one of the most well characterized viruses and has become a useful model system for understanding the biology of RNA viruses. It infects human cells by binding to an immunoglobulin-like receptor on the cell surface. The three...
Hepatitis A, caused by hepatitis A virus, is an acute infectious disease of the liver that is transmitted person to person by ingestion of contaminated food or water or through direct contact with an infectious person. Millions of people are believed to become infected with HAV every year. The incubation period is two to six weeks and on average is 28 days. In less developed countries the HAV is usually contracted in early childhood. Clean water helps to decrease contraction of HAV. In 90%...
Foot-and-mouth disease, FMD, is sometimes fatal and is highly contagious for cloven-hoofed animals. Along with hooved animals hedgehogs and elephants are susceptible to the disease as well. Llama and alpaca can develop mild symptoms but are resistant to the disease and don't pass it to other species. Mice, rats, and chickens have been infected artificially in a lab but it is not believed they can contract the disease under natural conditions. Humans can spread the disease by carrying the...
Human rhinoviruses are the most common viral ineffective agents in humans and are the cause of the common cold. The infection proliferates between 33-35 Â°C causing most reproduction to occur in the nose. It is a species in the genus Enterovirus of the Picornaviridae family of viruses. There are 99 recognized types of Human Rhinoviruses that are differentiated by their surface proteins. They are amongst the smallest viruses and lytic in nature. They travel via aerosols of respiratory...
