“Zombie” pigeons appear in Moscow, what’s going on?

According to the British "Guardian" report on August 19, a large number of pigeons have died in Moscow recently. The diseases contracted by these pigeons may be spread among humans. Recently, some media and blogs in Moscow reported that some pigeons will become like "zombies" and fall from the sky to death.

The Moscow Environmental Inspectorate’s Office has ordered environmental and municipal agencies to investigate. Experts discovered that the pigeons were suffering from these strange symptoms because they were infected with Newcastle disease, which can be transmitted to humans. A science columnist wrote on the website: "Before they died, these pigeons were like zombies: they lost their sense of direction, flew around, and then fell from the air, without the strength to stand up." It was also found in some dead birds. Salmonella. But more dangerous diseases such as bird flu and psittacosis have not been detected.

Newcastle virus can seriously affect the respiratory, digestive and nervous systems of poultry. It is highly contagious among poultry and is a poultry infectious disease with a high fatality rate. Salmonella is found in infected animals and their feces. Typical symptoms of Salmonella infection in humans are fever, diarrhea and abdominal cramps.

Although there is currently no large-scale avian plague, experts are worried that hot weather will make it easy for germs to spread, which may threaten human health.

Newcastle Disease Virus

This is a disease endemic to domesticated livestock and wild birds. This disease is caused by paramyxovirus. The virus can attack the intestines, stomach, respiratory system and nervous system. Depending on the type of virus, Newcastle Influenza Disease (DELE) can lead to clinical infection, and the mortality rate of infected birds can be as high as 100% without symptoms or a range of symptoms.

Birds of all ages can become infected, but mortality is highest among young birds.

Newcastle influenza is widespread among domesticated poultry (ducks, geese, turkeys), quail, pigeons, pheasants, and a variety of wild and domestic birds. All species of birds are susceptible to Newcastle flu disease (NDV), and different birds have varying likelihoods of contracting a specific strain of Newcastle flu disease. But all species are sources of infection for other species.
