“…These interventions may have caused a decrease in the number of airborne/droplet transmitted diseases from 2019 to 2020, with a reduction of 2,700 cases and a percentage change of -28.1%, which was observed in this study. This is consistent with other reports [ 17 , 20 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ], which revealed decreased influenza activity, Mycoplasma pneumoniae pneumonia, streptococcal pharyngitis, respiratory syncytial virus infection, measles, and TB in other countries. These findings support the rationale that COVID-19 prevention measures may have a similar effect in preventing other airborne/droplet transmitted diseases.…”

Introduction The impact of the COVID-19 pandemic on the incidence of notifiable infectious diseases (NIDs) in Taiwan remains unclear. Materials and Methods The number of cases of NID (n = 42) between January and September 2019 and 2020 were obtained from the open database from Taiwan Centers for Disease Control. Results The number of NID cases was 21,895 between January and September 2020, which was lower than the number of cases during the same period in 2019 (n = 24,469), with a decline in incidence from 102.9 to 91.7 per 100,000 people in 2019 and 2020, respectively. Fourteen airborne/droplet, 11 fecal-oral, seven vector-borne, and four direct-contact transmitted NID had an overall reduction of 2,700 (-28.1%), 156 (-23.0%), 557 (-54.8%), and 73 (-45.9%) cases, respectively, from 2019 to 2020. Similar trends were observed for the changes in incidence, which were 11.5 (-28.4%), 6.7 (-23.4%), 2.4 (-55.0%), and 0.3 (-46.2%) per 100,000 people for airborne/droplet, fecal-oral, vector-borne, and direct-contact transmitted NID, respectively. In addition, all the 38 imported NID showed a reduction of 632 (-73.5%) cases from 2019 to 2020. In contrast, 4 sexually transmitted diseases (STDs) showed an increase of 903 (+7.2%) cases from 2019 to 2020, which was attributed to the increase in gonorrhea (from 3,220 to 5,028). The overall incidence of STDs increased from 52.5 to 56.0 per 100,000 people, with a percentage change of +6.7%. Conclusion This study demonstrated a collateral benefit of COVID-19 prevention measures for various infectious diseases, except STDs, in Taiwan, during the COVID-19 epidemic.

“…and observations from other countries [ [3] , [4] , [5] , 9 , 26 ] is that NPIs, followed by a mask mandate, may have sustained impact on the circulation of respiratory viruses. This impact may be more pronounced during summer, when respiratory viral activity is low in general; however, similar effects were observed during Southern Hemisphere winter [5] , [6] , [7] . This implies a beneficial effect of NPIs, given the substantial morbidity and mortality not only of COVID-19 and influenza, but also other viral ARIs including RSV, one of the most important agents of severe lower respiratory tract infections in young children [ 35 , 36 ].…”

“…Prior to the COVID-19 pandemic, the impact of NPIs, implemented on a nationwide scale, on the circulation of respiratory viruses has been vastly unknown. During the first wave of the pandemic, it emerged that NPIs impacted not only SARS-CoV-2 but also influenza virus [ 3 , 4 ] with a pronounced decline of influenza activity during Southern hemisphere winter [5] , [6] , [7] ; and that pediatric hospitalizations due to non-COVID-19 respiratory illnesses decreased substantially [ 8 , 9 ]. However, national-level lab-based surveillance data characterizing the effect of NPIs on multiple respiratory viruses is currently scarce to the best of our knowledge.…”

Background During the initial COVID-19 response, Germany's Federal Government implemented several nonpharmaceutical interventions (NPIs) that were instrumental in suppressing early exponential spread of SARS-CoV-2. NPI effect on the transmission of other respiratory viruses has not been examined at the national level thus far. Methods Upper respiratory tract specimens from 3580 patients with acute respiratory infection (ARI), collected within the nationwide German ARI Sentinel, underwent RT-PCR diagnostics for multiple respiratory viruses. The observation period (weeks 1-38 of 2020) included the time before, during and after a far-reaching contact ban. Detection rates for different viruses were compared to 2017-2019 sentinel data (15350 samples; week 1-38, 11823 samples). Findings The March 2020 contact ban, which was followed by a mask mandate, was associated with an unprecedented and sustained decline of multiple respiratory viruses. Among these, rhinovirus was the single agent that resurged to levels equalling those of previous years. Rhinovirus rebound was first observed in children, after schools and daycares had reopened. By contrast, other nonenveloped viruses (i.e. gastroenteritis viruses reported at the national level) suppressed after the shutdown did not rebound. Interpretation Contact restrictions with a subsequent mask mandate in spring may substantially reduce respiratory virus circulation. This reduction appears sustained for most viruses, indicating that the activity of influenza and other respiratory viruses during the subsequent winter season might be low,whereas rhinovirus resurgence, potentially driven by transmission in educational institutions in a setting of waning population immunity, might signal predominance of rhinovirus-related ARIs.

“…The most interesting concept for diminishing cardiovascular disease during the COVID-19 pandemic may be an overall reduction of common infection by face masks and social distancing. These measures have recently been proven to be highly effective in reducing the spread of SARS-Cov-2, and may indeed hinder other viral infections [ 43 , 44 ]. And general viruses have shown to trigger atherosclerosis and plaque rupture resulting in neuro- and cardiovascular morbidity [ 45 , 46 ].…”

Decline and Recurrence of Stroke Consultations during the COVID-19 Pandemic Lockdown Parallels Population Activity Levels

et al. 2021

Background: The COVID-19 pandemic lockdown (CPL) lead to a significant decrease in emergency admissions worldwide. We performed a timely analysis of ischemic stroke (IS) and related consultations using the telestroke TEMPiS “working diagnosis” database prior (PL), within (WL), and after easing (EL) of CPL. Methods: Twelve hospitals were selected and data analyzed regarding IS (including intravenous thrombolysis [intravenous recombinant tissue plasminogen; IV rtPA] and endovascular thrombectomy [EVT]) and related events from February 1 to June 15 during 2017–2020. In addition, we aimed to correlate events to various mobile phone mobility data. Results: Following the significant reduction of IS, IV rtPA, and EVT cases during WL compared to PL in 2020 longitudinally (p values <0.048), we observed increasing numbers of consultations, IS, recommendations for EVT, and IV rtPA with the network in EL over WL not reaching PL levels yet. Absolute numbers of all consultations paralleled best to mobility data of public transportation over walking and driving mobility. Conclusions: While the decrease in emergency admissions including stroke during CPL can only be in part attributed by patients not seeking medical attention, stroke awareness in the pandemic, and direct COVID-19 triggered stroke remains of high importance. The number of consultations in TEMPiS during the lockdown parallels best with mobility of public transportation. As a consequence, exposure to common viruses, well-known triggers for acute cerebrovascular events and other diseases, are reduced and may add to the decline in stroke consultations. Further studies comparing national responses toward the course of the COVID-19 pandemic and stroke incidences are needed.
