How to express the path or method by which something (disease, signal, information) is transmitted in Japanese.
The path by which an infectious agent spreads.
Standard medical/public health term for 'route of infection' or 'transmission route'. Used for diseases.
このウイルスの感染経路はまだ不明です。
The transmission route of this virus is still unknown.
Similar to 感染経路 but emphasizes contagion. Slightly more technical or older usage.
伝染経路を特定することが重要です。
It is important to identify the transmission route.
The path a signal or data takes from source to destination.
Used for transmission paths in telecommunications, networking, or data communication.
データの伝送経路に障害が発生しました。
A failure occurred in the data transmission route.
Communication path or channel. Broader than 伝送経路, can include logical routes.
通信経路を暗号化する必要があります。
We need to encrypt the communication route.
Specifically for signal paths, often in electronics or control systems.
信号経路にノイズが入っています。
There is noise in the signal path.
The channel through which information or secrets are passed.
General phrase for 'information transmission route'. Can be used for leaks, rumors, or official channels.
その情報の伝達経路を調査しています。

Specifically for leaks (data, secrets). Emphasizes unauthorized outflow.
個人情報の流出経路が判明しました。

伝動経路に異常はありませんか？

These compound nouns are not interchangeable. 感染経路 is only for infections. 伝送経路 is for signals/data. 伝達経路 is for information or mechanical force. Choose based on what is being transmitted.
感染経路を遮断する。
Block the transmission route (of infection).
伝送経路を確保する。
Secure the transmission route (for data).
Directly translating 'transmission route' as 伝送ルート or トランスミッションルート is unnatural. Use the appropriate compound with 経路 (けいろ) or ルート in technical contexts.
感染ルート
