US Sounds Alarm: Deadly Bird Flu Virus Spreads to Pigs for the First Time, Raising Concerns of a Potential Pandemic

3. Lessons from the past:

Pigs have been the source of serious influenza pandemics in the past. Including the H1N1 epidemic, which increases concern about this discovery.

Richard Webbe, a virologist at St. Jude Children’s Hospital who studies animal and avian influenza for the World Health Organization, said pigs were the source of the 2009-2010 H1N1 influenza pandemic and have been identified as the source of other outbreaks. The discovery of the virus in a small farm makes the infection in pigs less worrying than that found in a commercial farm.

Lessons from the 1918 Spanish Flu:

The 1918 Spanish flu pandemic killed an estimated 50-100 million people worldwide. Scientists debate its exact origins. There are various theories. It didn’t start with birds, pigs, or humans, but what is clear is that this virus (H1N1) can spread quickly and severely among humans. causing enormous harm to humanity Recent studies suggest that the virus may have originated in wild birds before jumping from species to humans. It may or may not pass through other intermediary animals.

Current situation of avian influenza

This new case comes in the midst of a complicated avian flu epidemic in the United States:

– H5N1 infection has been detected in dairy cows in several states. As of October 2024, there were 320 affected dairy farms in 14 states.

– There have been 27 human cases in the United States, most of which came into contact with infected poultry or dairy cows.

– The Centers for Disease Control is closely monitoring the situation and genetically decoding virus samples.

Public health response

Health authorities are likely to intensify surveillance and control measures. The Centers for Disease Control, the Department of Agriculture and other agencies have joined forces to use a One Health approach to manage the avian influenza outbreak.

Although the risk to the general public remains low. But this discovery in pigs reinforces the importance of continued surveillance and research to prevent the spread and possible mutations of the H5N1 virus.
