Subsequently to the publication of the above article, the authors have realized that an error was introduced in the preparation of Fig. 2B for publication. In Fig. 2B, the lanes shown for the western blot were misannotated. Additionally, in the legend of Fig. 2C, '24 h post‑infection' should have been written as '12 h post‑infection'. Furthermore, the description of the data shown in Fig. 2B in the Results section (sentence commencing on p. 1635, the subsection 'HTNV activates caspase‑1 and pro‑IL‑1β in THP‑1 cells', line 10), was incomplete. The sentence here should have read as follows (the added text is highlighted in bold): 'In order to investigate whether caspase‑1 was activated during HTNV infection, the culture supernatant of HTNV‑infected THP‑1 was ultra‑filtered and an increased concentration of secreted caspase‑1 was detected post‑infection compared with the Mock group; similar results were also observed in the LPS‑ and ATP‑stimulated groups (Fig. 2B)'. The correct version of Fig. 2, with the lanes of the western blot in Fig. 2B labelled correctly and the appropriate changes having been made to the Figure legend, is shown opposite. The errors associated with this Figure did not have an impact on the overall meaning of the paper, or on the reported conclusions of this study. The authors regret that this Figure was not corrected prior to the publication of this article, and apologize to the readership for any inconvenience caused.
