The NCDC Director General, Dr Chikwe Ihekweazu, made this known in an interview, yesterday in Abuja, while providing highlights of the epidemiological situation and response activities in Nigeria.
Avian Influenza is strains of the influenza virus that primarily infect birds, but can also infect humans.
This type of flu is most often contracted by contact with sick birds, and can also be passed from person to person.
It spreads by airborne respiratory droplets (coughs or sneezes).
Symptoms begin within two to eight days, and are like the common flu.
Cough, fever, sore throat, muscle aches, headache and shortness of breath may occur.
Ihekweazu said as of March 24, 2021, the seven states reported outbreaks of Highly Pathogenic Avian Influenza (HPAI) cases (H5N1) in poultries.

Ihekweazu stated that all contacts were farmers, farm workers, bird handlers and traders, adding that the contacts were still asymptomatic except one who presented catarrh.

“Of 83 human samples collected, 64 (87.7 per cent) samples were analysed using Real time Reverse transcription polymerase chain reaction (RT-PCR). Of 64 samples analysed, only 7 (10.9 per cent) were positive for Flu A.

“Of the seven samples positive for Flu A, only six “85.7 per cent “were positive for A/H5 while one (14.3 per cent) was unsubtyped. All seven positive samples have been shipped to WHO Coordinating centre for further lab analysis,” he said.

The NCDC boss noted that sensitisation was carried out by the national and state RRT to farm owners, workers, Live Bird Market (LBM) associations and communities in the affected states.

He added that biosecurity measures were extensively discussed for the benefit of the farmers and communities...

DJ Conflicting info on human-to-human risks of spread...NOT GOOD !!!

Nice catch, Josh!  


One to watch!

Since "it is in Africa" limited reporting.

Nigeria reports H5 avian flu infections in poultry workers

Nasal swab testing of poultry workers and handlers in recent highly pathogenic H5N1 avian flu outbreak settings in Nigeria turned up seven positive results in humans, the European Centre for Disease Prevention and Control (ECDC) said in its weekly communicable disease threat report.
So far this year, Nigeria has reported 30 H5N1 outbreaks in poultry, spanning seven states. As part of outbreak investigations, health officials tested 83 people, none of whom were experiencing symptoms.
The group included farmers, bird handlers, and traders in four states: Kano, Bauchi, Kano, and Plateau. Real-time polymerase chain reaction on 64 samples found that 7 that were positive for influenza A. Six were H5, and 1 was unsubtypable. The samples have been shipped to a World Health Organization collaborating lab in the United States for further characterization.
Investigators have also collected blood samples from 13 close contacts of people in three of the affected states.
The ECDC said different H5 viruses are circulating in West African countries, and more epidemiologic and virologic details are needed to assess the situation, but for now, it considers the risk of zoonotic spread in European countries to be very low.
So far, the human cases haven't been confirmed as H5N1, though the ECDC reported a single H5N1 case in Nigeria in 2007.

Laos reports first human H5N6 avian flu case

Laos has reported its first human H5N6 avian flu case, the first known infection to occur outside of China.
The patient is a 5-year-old boy from Luang Probang province in the north central part of the country whose symptoms began on Feb 28, according to the weekly communicable disease threat report from the ECDC. He was hospitalized and recovered from his infection.
An investigation found that he had been exposed to poultry, which also tested positive for H5N6. No similar infections were found among his contacts at home or in the hospital.
H5N6 has been detected in poultry in China and a handful of other nations since 2014, but until the Laos case, human cases involving the strain had been detected only in China. The ECDC said the latest case raised the global total to 32, including 17 deaths. All but 5 cases involved poultry exposure, and so far the virus hasn't been linked to case clusters.

Some aspects;

-Symptoms of "bird flu in humans" may look like covid19

-Allthough H5 birdflu types show up around the globe a major risk is in countries we keep poor. There testing is very limited, hardly any sequencing...

-H5 bird flu so far often-in human cases-did jump from birds to humans and has seen hardly any further spread. 

[url]https://en.wikipedia.org/wiki/Avian_influenza[/url] or https://en.wikipedia.org/wiki/Avian_influenza has lots of variations. It can jump from birds to other species and then turn into a risk for humans. "Bird Flu" is also "double airborne" -as well via birds as via aerosols...

From the wikipedia page; 

Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds.[1][2][3][4][5][6][7] The type with the greatest risk is highly pathogenic avian influenza (HPAI). Bird flu is similar to swine fludog fluhorse flu and human flu as an illness caused by strains of influenza viruses that have adapted to a specific host. Out of the three types of influenza viruses (AB, and C), influenza A virus is a zoonotic infection with a natural reservoir almost entirely in birds.[8] Avian influenza, for most purposes, refers to the influenza A virus.

Though influenza A is adapted to birds, it can also stably adapt and sustain person-to-person transmission.[8] Recent influenza research into the genes of the Spanish flu virus shows it to have genes adapted from both human and avian strains. Pigs can also be infected with human, avian, and swine influenza viruses, allowing for mixtures of genes (reassortment) to create a new virus, which can cause an antigenic shift to a new influenza A virus subtype which most people have little to no immune protection against.[8]

Avian influenza strains are divided into two types based on their pathogenicity: high pathogenicity (HP) or low pathogenicity (LP).[9] The most well-known HPAI strain, H5N1, was first isolated from a farmed goose in Guangdong Province, China in 1996, and also has low pathogenic strains found in North America.[9][10] Companion birds in captivity are unlikely to contract the virus and there has been no report of a companion bird with avian influenza since 2003. Pigeons can contract avian strains, but rarely become ill and are incapable of transmitting the virus efficiently to humans or other animals.[11]

Between early 2013 and early 2017, 916 lab-confirmed human cases of H7N9 were reported to the World Health Organization (WHO)

DJ -We have to see how bad 2021 may get. I think less spread of flu-types due to Covid19 in human hosts-in 2020- may see more spread of flu virusses in other hosts-simply because the virus needs to reproduce itself somewhere...So maybe this corona-pandemic could result indirect in "indirect bird flu increases ending at human hosts" ?
