"Human Transmission of Viruses to Animals Outpaces Animal Transmission to Humans, Study Shows"

A study analyzing nearly 12 million virus genomes found that humans give more viruses to animals than animals give to humans, with 64% of human-to-animal transmissions involving pets, domesticated animals, birds, primates, and wild animals. The study highlights the significant impact of humans on the environment and animals, emphasizing the potential for viruses to jump between different species through close contact. Zoonotic diseases, such as COVID-19 and bird flu, pose a major threat due to the lack of pre-existing immunity in host species, with many pathogens circulating in humans having been acquired from animals at some point in time.

"Assessing the Human Risk of 'Zombie Deer Disease' as Experts Push for Preventative Measures"

Scientists are investigating the potential for the zombie deer disease, also known as chronic wasting disease (CWD), to spread to humans through experimental studies. While no human cases have been reported, the rising number of cases in the US has raised concerns. CWD is a prion disease affecting deer, elk, and other animals, with prions spread through bodily fluids. The cause of misfolding in prion proteins remains a mystery, but researchers are working to understand the risk of transmission to humans, with conflicting evidence and structural differences from mad cow disease.

"Rising Concerns: Zombie Deer Disease's Potential Threat to Humans"

Chronic Wasting Disease, also known as "zombie deer disease," is a neurodegenerative condition affecting wildlife such as deer, moose, and elk. While there have been no reported cases of transmission to humans, experts are concerned about the potential for animal-to-human transmission based on experimental studies and the history of other prion diseases. Surveillance efforts are ongoing, and researchers are working on potential live tests for CWD to mitigate the risk of human consumption of infected deer. However, there is still uncertainty about the possibility of CWD breaching the species barrier, and concerns remain about the potential impact of climate change and the emergence of novel CWD prion strains.

"First Recorded Death from Alaskapox Virus Confirmed in Alaska"

An elderly man from the Kenai Peninsula in Alaska has become the first person to die from Alaskapox, a recently discovered zoonotic disease thought to be carried by small woodland animals like squirrels. The man, who had a history of drug-induced immunosuppression due to cancer treatment, had been scratched by a stray cat he cared for before developing symptoms. Despite initial misdiagnoses, advanced testing by the CDC confirmed the presence of Alaskapox. The case suggests the virus may be more geographically widespread in Alaska's small mammals than previously known, prompting increased statewide awareness.

"Groundbreaking Discovery: University of Arkansas Researchers Uncover Novel Rodent Virus"

Biologists at the University of Arkansas have discovered a new virus called Ozark orthohantavirus (Ozark virus) in rats in Benton and Washington County, part of the Ozark Plateau. While there is no evidence of the virus spreading to humans, further evaluation is warranted due to its close relation to other disease-causing viruses. The distribution of the virus beyond Northwest Arkansas is still unknown. Researchers at the university are studying viruses transmitted from animals to humans to catch and prevent the early spread of infectious diseases, as most new infectious diseases originate from animals.

Anthrax Outbreak in Uganda: Mystery Disease Identified

A mystery disease that has killed up to 17 people in Uganda has been confirmed as anthrax, according to health officials. The outbreak in Kyotera district has caused infected patients to suffer from rashes and swollen limbs before succumbing to the illness. Initially ruled out by the Africa Centres for Disease Control and Prevention, tests have now confirmed the presence of the bacterial infection, which is typically found in cows, sheep, and goats. It is believed that contaminated meat may have caused the infection, as a number of cattle have also died during the outbreak. International and local health bodies are increasing disease surveillance in Africa due to the continent's vulnerability to deadly pathogens that can jump from animals to humans.

"Uganda's Deadly Mystery Illness Claims 14 Lives, Sparks Fear"

Health experts in Uganda are investigating a mysterious disease outbreak that has killed at least 14 people and affected around 40 others. The disease, which causes rashes and swollen limbs, is believed to be transmitted from animals to humans. Initial suspicions of anthrax have been ruled out, and further investigations are underway. Local communities are living in fear, resorting to traditional healing methods as medical professionals struggle to identify the illness. The disease may potentially be cellulitis, a bacterial skin infection that can lead to serious health complications if left untreated. International and local health organizations are increasing disease surveillance efforts in Africa due to its vulnerability to outbreaks and pandemics.
