Millions of pigs killed due to African Swine Fever in Various Countries #AfricanSwineFever

African Swine Fever Alert

The African swine fever (ASF) pandemic will be even worse this year than in 2019, say experts, warning that the spread of the highly contagious virus, which is fatal to pigs, is unrelenting.

With world attention on the human viral pandemic of Covid-19, concern is growing that countries are not focusing enough on halting the spread of ASF through better biosecurity practices, cooperation on intensive vaccine development, or transparency regarding outbreaks.

“The ASF virus is a much ‘stronger’ virus [than Covid-19], in that it can survive in the environment or processed meat for weeks and months,” Dirk Pfeiffer, a professor of veterinary sciences at City University in Hong Kong and a leading expert on ASF, told the Guardian.

ASF kills almost 100% of the animals it infects, and despite being in circulation for nearly 100 years, there is still no vaccine.

ASF had been a problem for many years, but when it reached China in autumn 2018 the disease exploded and the following year saw huge numbers of deaths. The official count was of around 1.1 million pigs culled in the year after that according to the UN Food and Agriculture Organization (FAO).

Unofficially, however, China’s numbers were probably closer to 200 million or more pigs culled, slaughtered early or lost to the disease in the first year of the outbreak. Last July the Dutch bank Rabobank estimated that at least 40% of the country’s 360 million pig population could have been lost.

The World Organisation for Animal Health (OIE), the UN agency based in Paris which monitors all notifiable animal diseases, told the Guardian it considered this “a reasonable estimate”.

Data from OIE for this year shows that global ASF numbers by the end of April are close to or already above levels for all of 2019. Currently, focal locations of the virus are primarily in China, Vietnam, the Philippines and a wide swath of Eastern Europe.

“The continuing new ASF outbreaks – which are reported through official OIE notifications, as well as picked up informally through media, and tracked through our emergency prevention system – confirm the ever-larger number of affected animals and the unrelenting spread of the disease,” Andriy Rozstalnyy, an animal health officer at the FAO told the Guardian.

Deaths from sickness total more than 100,000, nearly the same as 2019, and the number officially culled stands at 5.4 million compared to the 6.9 million figure from 2019.

The disease has now spread to northern India for the first time, as well as to Papua New Guinea. Recent outbreaks among wild boar populations in Belgium, now under control, have also heightened monitoring in western Europe.

“I think we can call it a pandemic, definitely,” said Timothée Vergne, an associate professor of veterinary public health at the National Veterinary School of Toulouse, France.

“I was expecting to see a significant decrease in the number of reports of ASF outbreaks [due to the Covid-19 crisis], but actually I was kind of amazed to see that it still goes on,” he said.

Overall numbers of reported outbreaks are “far above” what had been reported by the end of May last year, said Vergne, adding that he believes the overall numbers will eclipse 2019 by the end of the year.

There are also concerns that China is underreporting the data for 2020. “We see ASF every week here,” Wayne Johnson, veterinarian at farm services company Enable Agricultural Technology Consulting, who is based in Beijing. “Provinces are told not to report. China does not report anything that would give [an] accurate account.”

Pfeiffer, who had sounded warnings along with Vergne and other researchers in a 2017 paper from Veterinary Record about the potential global impacts of ASF getting into China’s pig population,said China has now gone from culling, to controlling and living with it. “The benefit that the ASF epidemic has had for the financial performance of the mega pig producers in China adds another interesting dimension to the story. They have actually learned to ‘live’ with the disease in the country, and benefit enormously from the high pork price.”
