BERLIN — For the second time in 10 days, Chancellor Angela Merkel on Thursday was seen shaking at a public event and struggling to maintain control of her body as her limbs trembled visibly. And for the second time in 10 days, Germany largely did not discuss it.

Her spokesman insisted she was well. German news outlets reported both episodes, but then quickly moved on, even though Ms. Merkel is widely seen as the most important leader in Europe and one of the most powerful politicians in the world.

One reason for the muted response at home could be rooted in Germans’ notoriously fierce protection of their own private lives, said Sudha David-Wilp, a senior trans-Atlantic fellow with the German Marshall Fund in Berlin. Such protectiveness extends to their leaders, she said.

“Also, they trust Merkel, and if she says she’s O.K.,” Ms. David-Wilp added, “they are going to take that at face value and give her the benefit of the doubt.”
