Vaccination of poultry in Hong Kong.
Vaccination against bird flu offers farmers hope, rather than being caught between the anguish of finding a sick bird and the desolation of having to slaughter their entire flock.
COVID has spread many times from humans to white-tailed deer and back again.
Animals, including the ones that live in our homes, can carry all kinds of illnesses. Most of the time it’s not a problem, but here’s what you should do to avoid getting sick.
From September onwards, migratory birds will arrive on Australian shores. If one is carrying the lethal bird flu, it could devastate our birdlife

Raw seafood dishes such as sushi, poke bowls and ceviche are increasingly popular, but can harbour fish-borne parasites. What’s the best way to protect ourselves?
Avian influenza (‘bird flu’) is a highly transmissible and usually mild disease that affects wild birds such as geese, swans, seagulls, shorebirds, and also domestic birds such as chickens and turkeys.

Avian influenza — commonly known as ‘bird flu’ — is infecting domestic and wild birds in Canada and around the world.

Floods are often followed by waves of diseases because pathogens shed by animals can survive in flood waters for days, raising the risk of infection for humans.

Authorities have been warned about five virus families that could cause future pandemics. Here are snapshots of the diseases each can cause and why we should be worried.

If surveillance focuses only on diseases that have already emerged, we’ll remain behind the curve. Better prediction of future pandemics will need to integrate animal, planetary and human health.
For the lab leak theory to be true, SARS-CoV-2 must have been present in the Wuhan Institute of Virology before the pandemic started. But there’s not a single piece of data suggesting this.
Data suggests most of the time infection results in either no symptoms or very mild disease for cats and dogs. And the duration of their symptoms, if they get them, may be very short.

This is not the first time that the monkeypox virus has spread beyond Africa, its continent of origin. But the current epidemic is unprecedented for a number of reasons.

Avian influenza virus — or bird flu — can infect domestic poultry such as chickens and turkeys, as well as wild birds. The H5N1 strain has been identified in Canada.

Scientists exploring the possibility of an animal origin for Covid-19 are still investigating the missing link between bats and human beings.
Following the global spread of COVID, there have been widespread calls for blanket bans on the consumption and trade of wild animals. But such bans may have unintended consequences.

The fear that SARS-CoV-2 will evolve in animals and then spread back to us in a more virulent form is unfounded.
Xenotransplantation is the transplanting of cells, tissues or organs from animals to humans. Pre-clinical trials of organ transplant from pigs have addressed some of the technical barriers.
New developments in organ transplants from animals show promise. However, there has been no public engagement about a potential risk. It may streamline a pathway to humans for new zoonotic diseases.
The delay in finding definitive answers to how novel infectious diseases come about is not unusual. Look at what happened to our search for Ebola virus.
White-tailed deer are one of the few wild species that scientists have found to be infected with the coronavirus – at least so far.
Scientists have been testing captive and wild animals for the coronavirus since the pandemic began. Only a few wild species are known to carry the virus, but many more have been shown to be susceptible.
