Abrupt termination of the 2019/20 influenza season following preventive measures against COVID-19 in Denmark, Norway and Sweden.

BackgroundIn mid-March 2020, a range of public health and social measures (PHSM) against the then new coronavirus disease (COVID-19) were implemented in Denmark, Norway and Sweden.AimWe analysed the development of influenza cases during the implementation of PHSM against SARS-CoV-2 in the Scandinavian countries.MethodBased on the established national laboratory surveillance of influenza, we compared the number of human influenza cases in the weeks immediately before and after the implementation of SARS-CoV-2 PHSM by country. The 2019/20 influenza season was compared with the five previous seasons.ResultsA dramatic reduction in influenza cases was seen in all three countries, with only a 3- to 6-week duration from the peak of weekly influenza cases until the percentage dropped below 1%. In contrast, in the previous nine influenza seasons, the decline from the seasonal peak to below 1% of influenza-positive samples took more than 10 weeks.ConclusionsThe PHSM against SARS-CoV-2 were followed by a dramatic reduction in influenza cases, indicating a wider public health effect of the implemented measures.

Association of Maternal SARS-CoV-2 Infection in Pregnancy With Neonatal Outcomes.

Importance: The outcomes of newborn infants of women testing positive for SARS-CoV-2 in pregnancy is unclear. Objective: To evaluate neonatal outcomes in relation to maternal SARS-CoV-2 test positivity in pregnancy. Design, Setting, and Participants: Nationwide, prospective cohort study based on linkage of the Swedish Pregnancy Register, the Neonatal Quality Register, and the Register for Communicable Diseases. Ninety-two percent of all live births in Sweden between March 11, 2020, and January 31, 2021, were investigated for neonatal outcomes by March 8, 2021. Infants with malformations were excluded. Infants of women who tested positive for SARS-CoV-2 were matched, directly and using propensity scores, on maternal characteristics with up to 4 comparator infants. Exposures: Maternal test positivity for SARS-CoV-2 in pregnancy. Main Outcomes and Measures: In-hospital mortality; neonatal resuscitation; admission for neonatal care; respiratory, circulatory, neurologic, infectious, gastrointestinal, metabolic, and hematologic disorders and their treatments; length of hospital stay; breastfeeding; and infant test positivity for SARS-CoV-2. Results: Of 88 159 infants (49.0% girls), 2323 (1.6%) were delivered by mothers who tested positive for SARS-CoV-2. The mean gestational age of infants of SARS-CoV-2-positive mothers was 39.2 (SD, 2.2) weeks vs 39.6 (SD, 1.8) weeks for comparator infants, and the proportions of preterm infants (gestational age <37 weeks) were 205/2323 (8.8%) among infants of SARS-CoV-2-positive mothers and 4719/85 836 (5.5%) among comparator infants. After matching on maternal characteristics, maternal SARS-CoV-2 test positivity was significantly associated with admission for neonatal care (11.7% vs 8.4%; odds ratio [OR], 1.47; 95% CI, 1.26-1.70) and with neonatal morbidities such as respiratory distress syndrome (1.2% vs 0.5%; OR, 2.40; 95% CI, 1.50-3.84), any neonatal respiratory disorder (2.8% vs 2.0%; OR, 1.42; 95% CI, 1.07-1.90), and hyperbilirubinemia (3.6% vs 2.5%; OR, 1.47; 95% CI, 1.13-1.90). Mortality (0.30% vs 0.12%; OR, 2.55; 95% CI, 0.99-6.57), breastfeeding rates at discharge (94.4% vs 95.1%; OR, 0.84; 95% CI, 0.67-1.05), and length of stay in neonatal care (median, 6 days in both groups; difference, 0 days; 95% CI, -2 to 7 days) did not differ significantly between the groups. Twenty-one infants (0.90%) of SARS-CoV-2-positive mothers tested positive for SARS-CoV-2 in the neonatal period; 12 did not have neonatal morbidity, 9 had diagnoses with unclear relation to SARS-CoV-2, and none had congenital pneumonia. Conclusions and Relevance: In a nationwide cohort of infants in Sweden, maternal SARS-CoV-2 infection in pregnancy was significantly associated with small increases in some neonatal morbidities. Given the small numbers of events for many of the outcomes and the large number of statistical comparisons, the findings should be interpreted as exploratory.

Public Health Agency of Sweden's Brief Report: Pregnant and postpartum women with severe acute respiratory syndrome coronavirus 2 infection in intensive care in Sweden.

The Public Health Agency of Sweden has analyzed how many pregnant and postpartum women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been treated in intensive care units (ICU) in Sweden between 19 March and 20 April 2020 compared with non-pregnant women of similar age. Cases were identified in a special reporting module within the Swedish Intensive Care Registry (SIR). Fifty-three women aged 20-45 years with SARS-CoV-2 were reported in SIR, and 13 of these women were either pregnant or postpartum (<1 week). The results indicate that the risk of being admitted to ICU may be higher in pregnant and postpartum women with laboratory-confirmed SARS-CoV-2 in Sweden, compared with non-pregnant women of similar age.

Confidence in the National Immunization Program among parents in Sweden 2016 - A cross-sectional survey.

BACKGROUND: Vaccination coverage for infant vaccinations in the Swedish National Immunization Program (NIP) has been high for more than a decade, with approximately 97% of 2-year-old children fully immunized. Vaccination coverage against Human Papilloma Virus (HPV) has been around 80% since introduction for girls in 2012. This indicates high parental confidence in the NIP, but as seen in other European countries rapid shifts in confidence may occur. This study examined vaccine confidence and attitudes towards vaccinations among parents in the Swedish population. METHODS: A web-based survey was sent to 1046 parents with children aged 0-15 years, in a panel administrated by The Public Health Agency of Sweden. The survey included questions on vaccination awareness, safety and information channels. The response rate was 87%. Data were weighted to adjust for non-responders and for representativeness of the Swedish population. RESULTS: Parents were categorized as acceptors (79%), questioning acceptors (19%) or selective refusers (2%). When excluding responses for HPV vaccination, the proportion of acceptors increased to 91%. The main reasons for questioning or refusing a vaccine were worry over adverse events, negative or lack of information. Along a spectrum of beliefs, acceptors and questioning acceptors were more similar compared to selective refusers. Nurses at child health clinics constituted the most used vaccination information source for acceptors, whereas selective refusers to a greater extent searched information online and in social media. CONCLUSIONS: The study demonstrates that parents in Sweden have confidence in and are positive towards vaccinations given within the NIP. One in five parents question vaccines, particularly regarding the HPV vaccine, but still concur to the NIP. Information on vaccines online and at vaccination appointments, including vaccine safety, is important for maintaining confidence in vaccination. Conducting recurring studies is valuable for monitoring vaccine confidence and changes in attitudes towards vaccination.

Seroprevalence and susceptibility to hepatitis A in the European Union and European Economic Area: a systematic review.

Most of the European Union (EU) and European Economic Area (EEA) is considered a region of very low hepatitis A virus (HAV) endemicity; however, geographical differences exist. We did a systematic review with the aim of describing seroprevalence and susceptibility in the general population or special groups in the EU and EEA. We searched databases and public health national institutes websites for HAV seroprevalence records published between Jan 1, 1975, and June 30, 2014, with no language restrictions. An updated search was done on Aug 10, 2016. We defined seroprevalence profiles (very low, low, and intermediate) as the proportion of the population with age-specific anti-HAV antibodies at age 15 and 30 years, and susceptibility profiles (low, moderate, high, and very high) as the proportion of susceptible individuals at age 30 and 50 years. We included 228 studies from 28 of 31 EU and EEA countries. For the period 2000-14, 24 countries had a very low seroprevalence profile, compared with five in 1975-89. The susceptibility among adults ranged between low and very high and had a geographical gradient, with three countries in the low susceptibility category. Since 1975, EU and EEA countries have shown decreasing seropositivity; however, considerable regional variability exists. The main limitations of this study are that the studies retrieved for analysis might not be representative of all EU and EEA publications about HAV and might have poor national representativeness. A large proportion of EU and EEA residents are now susceptible to HAV infection. Our Review supports the need to reconsider specific prevention and control measures, to further decrease HAV circulation while providing protection against the infection in the EU and EEA, and could be used to inform susceptible travellers visiting EU and EEA countries with different HAV endemicity levels.

Treatment of pediatric diarrhea: a simulated client study at private pharmacies of Ujjain, Madhya Pradesh, India.

INTRODUCTION: In low- and middle-income countries such as India, private pharmacies play an important role in medical treatments, offering advice for common illnesses such as diarrhea and respiratory tract infections. There is a need to explore the details of the dispensing practices at the private pharmacies in low- and middle-income countries. METHODOLOGY: The present study used simulated client methodology to assess the actual dispensing practices for patients with pediatric diarrhea at private pharmacies in an urban setting of an Indian province. RESULTS: This study identified 164 private pharmacies (84.10%) in the study setting that engaged in the practice of dispensing prescription drugs without prescriptions. Only about 40% asked clients if they had a prescription from a doctor. The average duration of consultations at the pharmacies was 1.3 minutes (range, 0.5-6 minutes). The dispensing of drugs was not in compliance with the recommended guidelines and regulations. The most commonly dispensed drugs were antibiotics (40.24%); of these, quinolones either alone or in combination with imidazoles were the most frequently dispensed. The other commonly dispensed drugs were antimotility drugs (31.10%) and Lactobacillus acidophilus (probiotics; 23.17%). The drugs were dispensed in inappropriate doses due to the absence of indications. CONCLUSIONS: Overuse and misuse of all these prescription drugs dispensed by pharmacies pose significant issues, such as resistance, dangerous side effects, and high costs. At the same time, the pharmacies did not dispense recommended drugs such as oral rehydration solution and zinc, which they are authorized to dispense without a prescription.

Parental attitudes and decision-making regarding MMR vaccination in an anthroposophic community in Sweden--a qualitative study.

Measles outbreaks occur regularly throughout Europe, up to 31500 cases in the previous year, particularly where there are pockets of populations with lower vaccination coverage than the recommended ≥ 95%. Anthroposophic communities in Europe are one of several groups with relatively low vaccination coverage. In Sweden, outbreaks of measles and rubella were reported from an anthroposophic community. Thus the aim of this qualitative study was to explore facilitators and barriers to MMR vaccination among parents living in anthroposophic communities in Sweden. Twenty parents living in an anthroposophic community were interviewed, focusing on their views and decisions on MMR vaccination. The interviews were analyzed using qualitative content analysis. Two overarching views of health emerged, differentiating broadly parents who vaccinate vs. parents who do not vaccinate. Four themes describing parental attitudes toward measles vaccination were developed and three of these, the conformers, the pragmatists and the attentive delayers describe different approaches toward vaccinations among those who actually vaccinate. The last theme, promoters of natural immunity, represents those postponing or refusing vaccination beyond childhood. This study suggests that there is a spectrum of parental beliefs regarding MMR vaccination in this anthroposophic community. Interventions specifically targeted to the anthroposophic community and strengthening health workers capacity for a constructive dialog on vaccine's benefit and risks may contribute to higher vaccination coverage. This is believed to minimize the risk of future epidemics and contribute to the WHO European Region's goal of eliminating measles.
