[&lt;span&gt;1&lt;/span&gt;] that describes the prevalence of respiratory infections caused by endemic human coronaviruses (eHCoVs) during the COVID-19 pandemic in Iran, indicating their low prevalence.&lt;/p&gt;&lt;p&gt;The COVID-19 pandemic has sparked a renewed interest in eHCoVs, which account for an estimated 5%–10% of acute respiratory infections (ARI) in temperate climates [&lt;span&gt;2&lt;/span&gt;]. These endemic human coronaviruses are widespread globally and generally result in mild to moderate infections of the upper respiratory tract. However, systematic surveillance data on the epidemiology of endemic coronaviruses NL63, HKU1, OC43, and 229E are currently lacking due to their underappreciated clinical and epidemiological impact. In pre-pandemic years, respiratory virus detections followed a stable seasonal pattern. Many studies, including the one discussed here, showed the low circulation of seasonal respiratory viruses, especially endemic coronaviruses, during the COVID-19 pandemic [&lt;span&gt;1, 2&lt;/span&gt;]. This was followed by a marked increase after the first and second lockdowns [&lt;span&gt;3&lt;/span&gt;]. Compared to 2019, respiratory virus numbers increased by 23% in 2020, 100% in 2021, and 270% in 2022 [&lt;span&gt;3&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;This reduction in virus circulation is mainly attributed to nonpharmaceutical interventions (NPIs) like travel restrictions, temporary lockdowns, school closures, mask-wearing, and improved hygiene practices. These measures likely played an important role in decreasing coronavirus transmission [&lt;span&gt;2&lt;/span&gt;]. However, evaluating the impact of NPIs is complex and influenced by factors such as pathogen characteristics, demographics, and timing and location of NPIs. Competition between SARS-CoV-2 and other viruses may also affect epidemiology [&lt;span&gt;4&lt;/span&gt;]. Additionally, prolonged periods of reduced exposure to common pathogens can lead to a temporary decrease in population immunity. With reduced exposure during the pandemic, people's immune systems might not be as prepared to fend off these endemic viruses once they re-emerge [&lt;span&gt;5&lt;/span&gt;]. The pandemic disrupted the usual circulation patterns of many viruses, allowing some viruses suppressed during the pandemic to find new opportunities to spread once normal activities resumed.&lt;/p&gt;&lt;p&gt;After the low circulation of eHCoVs during the COVID-19 pandemic, a seasonal increase in respiratory pathogens is expected. As it is mentioned in the Karami et al. article, surveillance research is essential to monitor eHCoV distribution patterns and identify changes in the epidemiology of these viruses. This is essential for developing strategies to timely control the future outbreaks of eHCoVs throughout the nation [&lt;span&gt;1&lt;/span&gt;].

RSV is known for causing severe respiratory illness, particularly in vulnerable populations. This development highlights the necessity of considering vaccination programs for other high-risk groups, such as healthcare workers (HCWs), who are frequently exposed to infected individuals and can serve as vectors for nosocomial transmission [&lt;span&gt;1&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Respiratory infections, particularly those caused by RSV, present significant challenges to healthcare systems worldwide, especially in the context of nosocomial transmission. HCWs, due to their frequent exposure to infected individuals, are at increased risk of RSV infection. However, data on the epidemiology of RSV infections among HCWs are limited. Understanding the extent of RSV infection in this group is crucial for implementing effective preventive measures and safeguarding both HCWs and the patients they care.&lt;/p&gt;&lt;p&gt;We performed a retrospective study to investigate RSV infections in nasopharyngeal swabs collected between January 2021 and April 2024 from HCWs with acute respiratory infection (ARI). Nasopharyngeal swabs were collected and placed in 2 mL of sterile lactate Ringer's solution, and RNA was purified using Extracta Kit Fast - DNA e RNA Viral (Loccus, Brazil), according to the manufacturer's instructions. RSV detection was performed by a one-step real-time RT-PCR with oligonucleotides targeting a conserved region of the matrix gene [&lt;span&gt;2&lt;/span&gt;] using AgPath-ID One-Step RT-PCR Reagents (Applied Biosystems, USA) with 5 μL of purified RNA, 800 nM of each primer, and 200 nM of the TaqMan probe. The reactions were performed on a Quantstudio 6 Pro Real-Time PCR System (Applied Biosystems) for 10 min at 50°C and 10 min at 95°C, followed by 45 cycles of 15 s at 95°C, and 30 s at 55°C (data collection). Samples with Ct ≤ 40 were considered positive. Further, RSV subtypes were identified by another real-time PCR specific for RSV A and B [&lt;span&gt;3&lt;/span&gt;] with the same conditions of the screening reaction.&lt;/p&gt;&lt;p&gt;A total of 4367 HCWs aged from 16 to 92 years (mean 38 ± 13, median 36) was tested, and RSV was detected in 2.6% (115/4367) of HCWs. The highest annual positivity rate was 3.6% in 2022 and the lowest was 1.9% in 2023 (Table 1).&lt;/p&gt;&lt;p&gt;The monthly RSV positivity ranged from 0% to 8.3% (March 2022–April 2024; Figure 1). Regarding RSV subtypes, 37.4% (43/115) were RSV A, 60.9% (70/115) were RSV B, and 1.7% (2/115) were unsubtyped. HCWs over 60 years old showed the highest detection rate (3.9%). Autumn–winter seasons (March–June in our region) showed the highest detections.&lt;/p&gt;&lt;p&gt;HCWs infected with RSV may serve as vectors for transmission within healthcare settings, potentially leading to outbreaks and absenteeism, compromising patient care.
