When a game of fetch can harm: leptospirosis can be transmitted to dogs (and humans) from stagnant water contaminated with rat urine.
Leptospirosis is spread by rats and other rodents, potentially killing dogs and humans. But we can protect ourselves and our pets.
The way humans share the world with wildlife has rapidly changed – and this is having a serious impact on the spread of pathogens.
Soon, this farmer and her goats could be treated with the same vaccine.

Rift Valley Fever infects millions of humans and livestock in Africa and Arabia. To fight it, scientists are developing a first of its kind vaccine that can be used on humans and animals.
Humans can easily transmit viruses to chimpanzees and other primates.
Human-to-ape disease transmission is thought to be a severe threat to the survival of great apes.
Little yellow-shouldered bat.
Scientists identify the risk of bat flu spreading to humans.
Rift Valley fever is a disease passed from mosquitoes to animals then to people.
Outbreaks of zoonotic diseases call for a collaborative approach to surveillance.
People and animals live side by side – and can have pathogens in common.
No one then knew a virus caused the 1918 flu pandemic, much less that animals can be a reservoir for human illnesses. Now virus ecology research and surveillance are key for public health efforts.
Tackling local diseases like rabies could help health authorities identify new outbreaks more easily.

By tackling local threats and controlling existing diseases, countries are able to build the capacity needed to deal with future emerging disease threats.
The Monkeypox virus was isolated most recently in 2012 from a dead infant mangabey (species of monkey) in Ivory Coast.
A disease suspected to be monkeypox is on the rampage in Nigeria. In less than one month, it has spread to seven of the country's 36 states and infected 31 people.
People who eat raw or undercooked meat from infected animals may get anthrax.
Governments in anthrax endemic countries should build efficient surveillance systems that incorporate detection, confirmation and efficient data collation and feedback.
The avian influenza strain of bird flu is thought to spread across continents via wild migratory birds.
Functional early warning systems help countries respond to a disease before it spreads.
People search for recyclable materials alongside animals at the Dandora Municipal Dumping Site in Nairobi.
Africa's cities are melting pots of activity and interaction. There are fears that the continent's next major modern disease crisis will emerge from them.
A woman developed sepsis after she was licked by her pet greyhound.
Uncollected rubbish provides food and shelter for rodents which can spread plague if they pick up the bacteria.
Plague, one of the deadliest diseases in the world, has been reported in several African countries in the past decade.
Frog chytrid may have been spread by humans. It is a fungus that has decimated amphibian species.
As much as animals may pass on viruses to humans, humans pass on viruses which are sometimes lethal to the animal world as well.
African camels could prove to be an important source of information about the MERS virus.
There is a high prevalence of the MERS virus in African camels. More research is key to understanding the virus better globally.
Two women walk in front of a billboard, which says “Ebola must go. Stopping Ebola is Everybody’s Business” in Monrovia, Liberia, January 15 2015.
Along with better strategies to respond to outbreaks in human populations, we need a stronger focus on surveillance in animals to identify infectious diseases before they pose a risk to human health.
Some rat, possum and mozzie species thrive when living close to people.
Our world is becoming increasingly urbanised. In 1950, just 30% of the world’s population lived in urban areas. This number is now over 50% and rising. By 2050, two-thirds of the world’s population are…
In an era flush with vaccines and antibiotics, when the greatest health risks in the developed world ride on the back of fried fish and hamburgers, it is easy to forget that infectious diseases still account…
Bats can harbour viruses such as Ebola and don’t display clinical signs of disease.
Bats are the natural host species for Ebola and a variety of viruses, many of which can be fatal when transmitted to humans. More than 100 viruses have been identified in bats and this number is rising…
