Dear Editor, the recent article on “Guillain-Barré syndrome (GBS) and Zika virus infection?
is very interesting[1]. Araujo et al. noted that “the incidence of GBS has increased in Brazil since 2015,
what is speculated to be secondary to the Zika infection outbreak[1].” Araujo et al.[1] also noted that “The diagnosis of GBS is feasible even in resource-limited areas
using the criteria proposed by the GBS Classification Group, which is based solely
on clinical grounds.” In fact, GBS is an important possible complication of Zika virus
infection[2]. However, there are some concerns. First, the first identification of the possible
interrelationship between GBS and Zika virus infection has just been proposed. There
has never been previous observation despite there were many previous big outbreaks
in the Pacific region. The next concern is on the rate of GBS. The question is there
any poofs that there is no other cause that can induce GBS. On the other hand, since
the Zika virus infection can be a silent infection and under diagnosed[3], hence, some GBS cases relating to Zika virus infection might be under diagnosed.
The Zika virus infection and its consequence, GBS, might be more common than expectation.
