You are only infectious during illness and it requires contact with fluids. It's exasperated by local funeral rituals where people interact with the dead body and get infected.
I wonder if you have sources on this? I heard that this is a new variant that has a much longer incubation time. A longer time until symptoms appear means it will spread much quicker and wider (that was also the issue with Covid that had a incubation time of 5 - 8 days).
This variant may have longer incubation time but you are almost not infectious without symptoms. The more symptomatic you become, the more you spread. This is in contrast to COVID or some flus where you are most infectious in the incubation period.
That it does not spread that easily and that its current spread is more a combination of factors in the specific area. War, hunger, refugees, culture and lack of education. It’s to say it’s hard for it to land and expand. Once you have symptoms the patient is also very quickly immobilized reducing the spread further.
