It seems like there ’s a new eruption of Avian Flu just about all the time . A couple of weeks ago I read about a new outbreak inFrancethat result in the culling of 600,000 duck .
Just a few years ago , the avian grippe hit two land aside from us . Even fowl funfair in my province were canceled , interstate poultry transport was outlawed , and backyard domestic fowl keepers were warned to watch for signs of illness in their flock .
I can tell you from experience – worrying that every wild bird flying overhead might be sway a death prison term to your beloved backyard flock is an unsettling feeling .
gratefully not every flu strain is deathly . Also , the most lethal outbreaks run to be incorporate apace , by sanction , due to our world dependence on poultry as a food beginning . Yet , if you keep or spend meter around domestic fowl , there are some thing you should know about avian influenza for your refuge and the wellbeing of poultry tidy sum .
What is Avian Flu?
We all do it what the “ flu ” is in humans . It ’s not a undivided affair , but a assembling of dissimilar computer virus strains that get human sicknesses .
Depending on which line of influenza you get , your symptom can range from meek to severe . The so - called “ swine influenza ” for example , laid many multitude up for more than a week . While a “ normal ” grippe might just make you feel under the conditions for a couple of days .
The same is reliable of avian or dame flu . They are n’t just one disease , but many different kind . Some just ensue in small malady that can be quickly countered by a healthy immune system . Others are lethal .
They are a risk to all birds include dotty birds and tame poultry . They can also be transmitted from birds to human .
LPAI or HPAI
Generally , avian flue are classed as either low pathogenic avian grippe ( LPAI ) or highly pathogenic avian grippe ( HPAI ) . LPAI virus are the balmy kind that commonly results in poultry recovering on their own .
The HPAI type viruses , by contrast , tend to spread rapidly and get deaths to entire mickle . HPAI avian grippe strains dumbfound an immediate and serious risk to our global intellectual nourishment supply . As a result , these types of avian grippe get quick media attention and touch off regional or statewide restrictions on poultry movement – such as what happen in my state in 2017 .
Unfortunately , when HPAI strains are found in a raft , the whole flock is usually culled to reduce the risk of the computer virus spreading . Additionally , in some circumstances , nearby passel may also be preemptively culled to ensure the virus is take .
Human Health Risks
It ’s important to note that several striving of HPAI can also impersonate lethal risks to human wellness . In special , the two most concerning strains are H5N1 and H7N9 .
1. H5N1
H5N1is fuck to produce severe illness and has a 60 % fatality rate rate when transmit to humans . Thankfully , it does n’t channelise well from poultry to humans or from human to human . It ’s most likely directly convey to homo through prolonged contact with infected snort or by close contact with contaminated carcase ( e.g. when processing ) .
2. H7N9
H7N9causes severe pneumonia in humans and require medical treatment to recover in most cases . There are a few instances where hoi polloi were able-bodied to recuperate at home without medical maintenance . Overall , though , even with restricted aesculapian care it has a human fatality rate rate of 40 % .
Known H7N9 casesin human were because of verbatim contact between the person who contracted the computer virus and the bouncy poultry that carried it . There are no known cases of human - to - homo transmission .
3. Other Avian Flu Strains
Severalother strainsof avian flu have been transmitted to humans through unmediated link with poultry . These other strains do n’t currently have the same high mortality rates as H5N1 and H7N9 . However , they can still cause human illness .
Safety Warning
Although domestic fowl to human transmission is considered rare , epidemiologists and researchers are concerned that these computer virus could potentially pose significant risks to human universe if outbreaks are not hold quickly .
In peculiar , people who have contact with springy domestic fowl such as by keeping them at plate or bribe them from live domestic fowl market seem to be at the great risk of exposure of sign up avian flu .
In the US , the peril for catch avian flu is still study very low-toned .
