“…Notably, the incidence of varicella, the number of reported cases and public health emergency events in Suzhou in 2020 decreased because of the COVID-19 epidemic. This phenomenon is not an exception and has been observed worldwide in different countries and cites [ 29 , 30 ]. In addition, diseases with a similar mode of transmission to varicella, such as hand, foot, and mouth disease, present varying degrees of decline in reported incidence in 2020 [ 31 ].…”

Background: The varicella vaccine is excluded from the Chinese national immunisation programme but is included in the local expanded programme on immunisation (EPI) in the Suzhou Prefecture. This study investigated the epidemiological characteristics of the varicella cases during the implementation of different immunisation strategies in the Suzhou Prefecture, Jiangsu Province. Methods: In this study, we used descriptive statistics. Information on reported instances from 2012 to 2021 was first retrieved. Data on varicella cases were collected from the China Information System for Disease Control and Prevention (CISDCP). Similarly, information on vaccinated children was obtained from the Jiangsu Province Vaccination Integrated Service Management Information System (JPVISMIS). The census data in this study was procured from the Suzhou Bureau of Statistics. Results: From 2012 to 2021, a total of 118,031 cases of varicella were reported in Suzhou, and the average annual reported incidence was 91.35 per 100,000. The average yearly incidence after implementing the two-dose varicella vaccination decreased by 41.57% compared with the implementation of one dose. This study demonstrates two annual incidence peaks, a small peak between April and July and a prominent peak between October and January. It is also possible that this seasonal distribution is related to the geography of Suzhou. The average annual reported incidence between districts with a statistically significant difference (χ2 = 98.077, p < 0.05). The one-dose varicella vaccination coverage gradually increased from 55.34% in 2012 to 89.06% in 2021 and the two-dose varicella vaccination coverage gradually increased from 0.27% in 2012 to 82.17% in 2021. Conclusions: Administering the varicella vaccine in the local EPI has significantly decreased the incidence rate and the total number of cases. A two-dose vaccination schedule is still the best vaccination strategy for varicella vaccine effectiveness.

“…In the period between the end of 2019 and the spring of 2022, the COVID-19 pandemic significantly influenced interpersonal contacts, which also have different impacts on measles, mumps and rubella vaccination efforts and burden across the world. For example, Brazil reported a reduction in the number of MMR vaccine doses [ 6 ], while interestingly, Japan reported de-creased estimated annual burdens in 2020 for measles (98%), mumps (47%) and rubella (94%) compared with those in 2019 due to social distances in COVID-19 pandemic [ 7 ]. However, due to the current burden of COVID-19 on public health institutions, one may expect a decrease in vaccination coverage and potential new outbreaks in near future.…”

Due to the current burden of COVID-19 on public health institutions, increased migration and seasonal touristic traveling, there is an increased risk of epidemic outbreaks of measles, mumps and rubella (MMR). The aim of the present study was to analyze the epidemiological data on MMR immunization coverage and the number of measles cases in 2001–2019 in Croatia and a number of European countries. Results revealed a decreasing trend in vaccination in 2001–2019 throughout Europe. However, Croatia and Hungary still have the highest primary and revaccination coverage, compared to other analyzed countries. The highest number of measles cases was in 2017 in Romania. There was no significant correlation between the percentage of primary vaccination and the number of measles cases (r = −0.0528, p = 0.672), but there was a significant negative correlation between the percentage of revaccination and the number of measles cases (r = −0.445, p < 0.0001). In conclusion, the results of the present study emphasize the necessity to perform a full protocol of vaccination to reach appropriate protection from potential epidemic outbreaks. Furthermore, in the light of present migrations, documenting the migrants’ flow and facilitating vaccination as needed is of utmost importance to prevent future epidemics.

“…Few recent studies have shown a decrease in multiple respiratory agents. [22][23][24][25][26] Interestingly, a case series study, that investigated hospitalisation rates of children under the age of 2 years due to lower respiratory infections, revealed a significant reduction in hospitalisation mainly caused by enveloped viruses. Incidence of unenveloped viruses such as rhinoviruses/enteroviruses did not show such impressive decrease.…”

“…The lower basic reproduction number (R 0 ) of influenza20 and IMD21 compared with that of SARS-CoV-2, is a possible explanation for the much stronger impact that those measures had on their transmission. Few recent studies have shown a decrease in multiple respiratory agents 22–26. Interestingly, a case series study, that investigated hospitalisation rates of children under the age of 2 years due to lower respiratory infections, revealed a significant reduction in hospitalisation mainly caused by enveloped viruses.…”

BackgroundAiming to the containment of the coronavirus disease 2019 (COVID-19) pandemic, governments worldwide have implemented a series of non-pharmaceutical interventions. Many of them and especially school closures have impacted the circulation of multiple airborne pathogens among children and adolescents. This study investigates the incidence of influenza and invasive meningococcal disease among children aged 0–14 years in Greece during the COVID-19 pandemic.MethodsData regarding the number of influenza-like illness cases, influenza-related paediatric intensive care unit (PICU) admissions and invasive meningococcal disease cases among children 0–14 years old were obtained from the National Public Health Organization. The incidence of the two diseases during the COVID-19 pandemic period (2020/2021) was compared with that of the six preceding seasons (2014–2019).ResultsA notable decrease was observed in both influenza and invasive meningococcal disease cases during the period 2020/2021 compared with the years 2014–2019. The mean annual rate of influenza-like illness cases and influenza-related PICU admissions in children 0–14 years old has reduced by 66.9% and 100%, respectively, while the mean annual invasive meningococcal disease rate has declined by 70%. Both weekly influenza-like illness and monthly invasive meningococcal disease rates were significantly decreased.ConclusionsThe activity of influenza and invasive meningococcal disease in the children and adolescents of Greece has decreased during the COVID-19 pandemic period. Reduced transmission is likely related to the public health measures that were implemented to control the pandemic. The value of these measures may have relevance to the future management of influenza or invasive meningococcal disease epidemics.
