Another Worldwide Pandemic Spreads-Between Pigs

A rash of pain flowers in China. Exactly how it came out, which is far from the eyes of anyone watching the scientist, no one can explain. It spread with incredible speed, killed in many places, froze transportation and trade, and caused a lot of economic turmoil. Hitchhike to travel the world, it’s around the world. There is no cure, and no vaccine. Inevitably, it will come to America, in July 2021.

Yup, 2021. The year is not a typo. This outbreak is not Covid; it was a similar, latent pandemic, a deadly animal disease called africa swine that was detected in the Dominican Republic in July. African swine fever poses no danger to humans, but is even more harmful to livestock: Those who die in China are millions of pigs, not less than a quarter-and possibly a half—Of the entire herd of the largest pork producer in the world.

In the United States, animal health authorities are now on high alert. The U.S. Department of Agriculture has promised one allocation emergency of $ 500 million to increase vigilance and prevent disease from crossing borders. Africa swine fever is feared internationally, if it is found in the US, pork exports-amount more than $ 7 billion a year-immediately break down.

“The far transboundary spread of severe infectious and pathogenic diseases is an even more serious situation,” Michael Ward, an epidemiologist and chairman of veterinary public health at the University of Sydney, told WIRED via email . “In agriculture, it’s the analogue of Covid-19.”

Like the Covid pandemic at its inception, there was no vaccine-but as with Covid, there is bright hope for one, thanks to the basic science that has set the findings over the years without much attention. Two weeks ago, a multinational group led by scientists at the USDA Agricultural Research Service announced that they had achieved a vaccine candidate, correlated with a weak version of the virus with a causal gene removed, and demonstrated its effectiveness in a field trial, in pigs, in Vietnam.

The vaccine candidate was made by a commercial partner, a Vietnamese company called Navetco, on a timeline that is not yet clear. This is the fifth vaccine in the experiment developed by the USDA team. (The first four were grown by private companies with no additional federal involvement.) Manufacturers.

Stop a little: Swine fever in Africa has long been an enemy of agriculture. Even if it destroys China’s pork industry, China is not a place of origin of the disease. The story of African swine fever actually began in Africa, almost exactly 100 years ago.

A Scottish veterinarian named Robert Eustace Montgomery, who worked for the British colonial government in East Africa, published the first description of it, in September 1921. Montgomery described the outbreak of a hemorrhagic disease. of harmful farm pigs “an owner… must prepare for a practical loss,” he wrote.

The new disease, caused by a virus, has become a regular companion to farming in East Africa. Wild pigs and warthogs have a port of it and often spread it to livestock; so are some types of ticks that eat pigs. The symptoms are always the same: Pigs develop fevers, lose their appetite, develop bleeding under their skin and in their internal organs, and collapse. Whenever the boar was brewed, it was burned by a herd of cattle and all the pigs were killed or extinguished if the farmers slaughtered their pigs to prevent it. The first farmers to observe the disease found that there was nothing to stop it but to restrain the pigs instead of letting them roam, and to build fences strong enough to keep the wild ones out. pig.
