Newcastle Disease : How long does it last in your coop

[Laurel09]

You don't have a diagnosis, you have a guess, so who knows? If it's something like Mycoplasma, every bird you have is still carrying the disease, so unless all your birds are dead and gone, it doesn't matter.
Air flow will spread organisms around, not kill them, depending on what's there. Vinegar is not a disinfectant either.
I don't think this is answerable given the lack of information here.

Sorry to bother but the situation to where i am is much worse than what you imagine

Actually i'm in Africa. And the authorities here in the region where i live don't even care about backyard flocks or anything, they are not as civilized like in countries where most of you guys live.Reporting won't help and for sure. I know there is no way they will test any chicken for diseases, they just ignore, so you kind of have to take care of your own business and that's the way it is here, everything is just DIY here and I'm very sure i won't find any vet doctor anywhere around so that's why i came to ask here,the only place where i have been getting help since i fell in love with chickens(BYC).

I heard there were cases of the disease in some parts of the country but no near where i am,I'm just assuming the worst so if anyone is going to provide answers, lets just work with the assumption that we are dealing with newcastle just to stay in the safe zone .

I read several articles online based on conducted research and lab experiments and they all seemed to say the same thing.

The virus is relatively stable outside of a host and in the environment, thus making fomite transmission a possibility. Infectious virus has been found to survive 7 days in the summer, 14 days during the spring, and 30 days in the winter in poultry houses that were contaminated by infected birds.

Survival Outside Host Virus is inactivated by heat and direct sunlight (30 minutes) but in non-laboratory environment, has been shown to remain 21 days in cool weather like poultry litter and sheds.

One study reported that APMV-1 survived in contaminated, uncleaned poultry houses for up to 7 days in summer, as long as 14 days in the spring, and 30 days during the winter. Another group reported virus isolation up to 16 days after depopulation of an unvaccinated flock.

When it comes to diseases an sickness in chickens it’s far easier, cost effective and better for your flock to kill any birds with any sickness that you believe is contagious. In the long run you’ll end up with a much healthier, disease resistant flock.

Sorry I assumed you were in the US. Most users here are in the US, but certainly not all. That's very presumptuous of me! It would help if you added your location to your profile. And you found good info. Interesting read!

I agree that all birds should be destroyed if there is vND involved. If the disease is common where you are, I'd likely disinfect the entire coop with bleach or something that really kills germs (vinegar won't cut it). I'd disinfect it regardless just because I wouldn't want to risk getting new chickens and having them get sick. Waste of money and life. I'd use 10 parts of water to 1 part bleach, scrub the coop, spray it down, and let it dry completely.

And what part of Africa are you in? Which country? I love that there are people from all over the world on this site!

Knowing your approximate location makes all the difference!
There are vaccines against Newcastle disease available some places, and you could look into that if it's possible where you live.
Otherwise, actually cleaning and disinfecting the premises matters.
Have you talked to other chicken keepers in your area/ country? Find out what's the best plan from people who have had a similar situation, at least.
All the best,
Mary

Thanks a lot, I'm from Zimbabwe. I will use bleach.I read on several sites that the virus lasts for about 7 days outside the host in summer and i think its 2 months now since i last used the coop and we are currently in summer right now.I will clean the coop one more time then spray the bleach all around coop.

The chicken was actually a new member that i wanted to introduce to the flock, and it died while it was still under quarantine. My main flock of 1 rooster and 5 hens is still in perfect health

If it was vND it can spread very easily over short distances on the bottom of your shoes, on tools and equipment, carried on the feet of flies and rodents, car tires, feed bags, on dust and feathers etc. This is why govt agencies here depopulate entire flocks within about a mile of locations where the disease is confirmed. They kill the uninfected birds to keep them from getting the disease from the environment and spreading it further.

It's still possible that your hen died of something else. But since you're trying to be safe by assuming the worst, you need to make a thorough biosecurity plan to keep your birds safe and prevent taking the disease off your property. Don't move your birds from your property or bring any new birds in. Don't share equipment with neighbors. Have a specific set of shoes that you never wear inside the house or off your property. Sanitize your quarantine area and all your equipment with a viricidal disinfectant. Confine your current birds for close observation and to prevent them from getting or spreading any illness to/from neighboring birds and wild ones. These are SOME of the things that we've been advised to do here, where we also have vND.
