In China, H3N8 Bird Flu Has Been Discovered in a 4-Year-old Kid!

China Bird Flu: H3N8 bird flu has been detected in a 4-year-old kid in central China, marking the first time the virus has been confirmed in humans. Scientists believe the 1889 epidemic was caused by an earlier strain of the virus, which can also be found in horses and dogs.

According to China’s National Health Commission (NHC), the youngster, from Zhumadian City in Henan Province, suffered fever and other symptoms on April 5 and was hospitalized on April 10 as his health worsened.

“On the 24th, the Chinese Center for Disease Control and Prevention tested a patient specimen provided from Henan Province, and the result was positive for the H3N8 avian influenza virus,” according to the NHC statement.

The boy had come into contact with hens and crows bred at his home in Zhumadian, a city located around 245 kilometers north of Wuhan and 715 kilometers northwest of Shanghai.

H3N8 is a virus that is prevalent in birds and horses, and it is one of two viruses that cause dog flu. Although researchers believe that a previous strain caused the 1889 pandemic, which was known as “Asian flu” and “Russian flu,” it had never been proven in a human.

According to the NHC, “experts’ preliminary opinion is that the H3N8 avian influenza virus is of avian origin and does not yet have the ability to infect people.” “This is a case of unintentional bird-to-human cross-species transmission with a low probability of widespread dissemination.”

The virus was not found in the child’s close contacts, according to the health commission. It advised people to stay away from poultry, especially sick or dead birds.

Bird Flu or Avian Influenza

Avian influenza, often known as bird flu or avian flu, is a kind of influenza caused by viruses that have been adapted to birds. The most dangerous strain is highly pathogenic avian influenza (HPAI).

As an infection caused by influenza virus strains that have evolved to a specific host, bird flu is similar to swine flu, dog flu, horse flu, and human flu. The influenza A virus is a zoonotic infection with a natural reservoir almost completely in birds, out of the three types of influenza viruses. For the most part, avian influenza refers to the influenza A virus.

Though influenza A is suited to birds, it may also adapt and survive transmission from person to person. According to recent influenza studies, the Spanish flu virus has genes adapted from both human and avian strains.

Pigs can be infected with human, avian, and swine influenza viruses, allowing for gene reassortment, which can result in an antigenic shift to a novel influenza A virus subtype against which most people have little to no immune resistance.

Avian influenza strains are classified as either high pathogenicity (HP) or low pathogenicity (LP) based on their virulence (LP).

H5N1, the most well-known HPAI strain, was first discovered in 1996 from a farmed goose in Guangdong Province, China, and has low pathogenic strains in North America. Companion birds in captivity are unlikely to transmit the virus, and no case of avian influenza has been reported in a companion bird since 2003.

Pigeons can get avian strains, but they rarely get sick and are unable to spread the virus to humans or other animals.

The World Health Organization received 916 lab-confirmed human cases of H7N9 between early 2013 and early 2017. (WHO).

On 9 January 2017, China’s National Health and Family Planning Commission reported to WHO 106 H7N9 cases that occurred between late November and late December, including 35 deaths, two possible cases of human-to-human transmission, and 80 of the 106 people saying they had visited live poultry markets.

Jiangsu, Zhejiang, Anhui , Guangdong, Shanghai, Fujian, and Hunan have all reported cases.

In recent years, throughout December and January, there have been similar spikes in the number of human H7N9 cases.

Bird Flu Prevention

People who do not come into contact with birds on a regular basis are not in danger of catching avian influenza. Workers on poultry farms, animal control officers, wildlife scientists, and ornithologists who work with live birds are all at risk.

Before any cases of avian influenza are identified, organizations employing high-risk personnel should have a plan in place.

Poultry flock biosecurity is also vital for prevention. Outside birds, particularly wild birds, and their waste should be isolated from flocks; vehicles used around the flock should be disinfected on a regular basis and not shared between farms, and birds from slaughter channels should not be returned to the farm.

Infection is unlikely with appropriate infection control and the use of personal protective equipment (PPE). Because these are the most common ways for the virus to enter the body, protecting the eyes, nose, mouth, and hands is critical for protection.

Aprons or coveralls, gloves, boots or boot covers, and a headcover or hair cover are all examples of appropriate personal protective equipment.

PPE that can be thrown away is advised. PPE should also include an N-95 respirator and unvented/indirectly vented safety eyewear. It’s also possible to wear a powered air-purifying respirator (PAPR) with a hood or helmet and face shield.

It is possible to prevent the spread of an isolated case by properly reporting it. If a worker experiences symptoms within 10 days of working with infected birds or potentially contaminated materials, the CDC recommends that they seek medical attention and report their employer, who should then alert public health officials.

The WHO recommends a three-phase, five-part plan for future avian influenza risks.

Pre-pandemic phase

Reduce the risk of human infection.
Increase the effectiveness of the early warning system

Phase 2: A pandemic virus emerges.

Contain or postpone the transmission of disease at the source.

Phase 3: A pandemic has been proclaimed and is spreading over the world.

Cut down on morbidity, death, and societal upheaval.
Conduct research to help you decide how to respond.
