its spread is unlikely, but the ghost of COVID left the alarms on

China’s health authority reported that it found the first case of human transmission of the H3N8 virus in a child as young as four years old who had contact with captive-raised chickens. The boy had a fever as well as other undescribed symptoms, and naturally the case drew attention because of its similarity to the December 2019 outbreak that slowly flooded the news from China, later becoming the deadliest pandemic in a hundred years.

After sequencing the virus, we now know that the H3N8 variant not yet capable of being transmitted between humansso a sudden outbreak seems unlikely according to Chinese authorities.

The recommendation for now has been limited to people avoiding contact with sick birds, alive or dead; and especially to pay attention to food hygiene.


With everything and the improbability that H3N8 is the engine of a new pandemic, in reality the alerts never went off. The European Union’s pandemic research project has said that the next pandemic could come from a new coronavirus, as happened with COVID-19, or, of a new influenza virusas happened between 2009 and 2010 with H1N1, which was first detected in Mexico and caused an outbreak that was quickly classified as a pandemic by the World Health Organization.

In either case, the outbreak would have to be unusually fast, and it will most likely be clear from the first sequencing that the virus can be transmissible between humans.

That flu viruses find a way to “jump” to humans is not new. In October 2021 alone, the CDC in the United States reported two new human infections due to different influenza viruses that usually spread in pigs and not between people. The case with the H3N8 variant was detected in Henan and transmission between dogs, horses and even seals has been found before. but never between humans.

Outbreaks that will be inevitable

The World Health Organization found 1,483 epidemic events in 172 countries from 2011 to 2018, of which six cases were declared an international health emergency. SARS and influenza viruses were the most common, but there were also references to MERS, Ebola, Zika and many more. History tells us that zoonotic outbreaks (the name given to diseases caused by pathogens initially discovered in animals) will not only continue to exist, but will increase in frequency.

The keys to understanding the increased risk are, unfortunately, very common: the deforestation of large portions of land erodes the natural barrier between human wild species. Processes such as urbanization, global trade and even certain types of tourism have the same effect, but there is also an aggravated risk with irregular farms operating in unsanitary conditions.

All this has led specialists and public faces on pandemic awareness such as Bill Gates to assure that it is only a matter of years before the next pandemic arrives. The question is whether the planet will be more prepared than it was for COVID-19. The answer varies depending on who you ask, but the 2021 Global Health Security Index, a report on health security that assesses countries’ ability to respond to epidemics and pandemics, detailed in 2021 that the world continues “dangerously underprepared“for the next outbreak.

Among the reasons, the report reads, is that more than 90% of countries do not have plans for the distribution of vaccines or medicines in times of emergency, that 70% of the 195 countries evaluated do not have sufficient hospital capacity, and that People trust their governments and health policies less and less.

China Reported The First Human Case Of H3n8 Avian Flu Its Spread Is Unlikely But The Ghost Of Covid Left The Alarms On

The evaluations translated into scores of 0 100, where the 195 countries obtained, on average, 38.9 points, less than the 2019 average, prior to the pandemic. At least in 2021 Mexico got 57 pointsnotably above average, but in reality no country scored more than 80.

SARS-CoV-2 will not cause more or fewer zoonotic outbreaks. Periodically, news about new human infections of diseases whose transmission was previously limited to animals will continue to jump. The alerts were turned on and that is good news, because the next challenge is that the discovery of the pathogen behind the next outbreak is soon enough to activate all the necessary control and mitigation protocols so that the next big disease does not produce the million deaths than COVID-19 does.
