mazonas state reported the first confirmed SARS-CoV-2 case in Manaus, the state capital, in March 2020 in a traveler returning from Europe 1 . By late February 2021, >306,000 laboratory-confirmed cases and more than 10,400 deaths in Amazonas had been reported 2 . The COVID-19 epidemic in Amazonas is, at the time of writing, characterized by two exponentially growing curves of cases (Fig. 1a). Epidemiological data from surveillance of severe acute respiratory illness (SARI) and burials indicate that the first wave of the epidemic started in March 2020 and peaked around early May 2020, when the number of cases dropped and then remained roughly stable from June to November 2020. However, in mid-December the number of cases started to grow exponentially, establishing the second wave of the epidemic.A new SARS-CoV-2 VOC, designated P.1 and also knowns as N501Y.V3, recently emerged in Manaus. Lineage P.1 was first detected in four travelers returning to Japan from Amazonas state on 2 January 2021 (ref. 3 ) and was soon recognized as an emergent lineage in Manaus 4 . The VOC P.1 harbors 21 lineage-defining mutations, including ten in the Spike protein (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, H655Y and T1027I). The emergence of P.1 was touted as one of the putative causes of the second wave of COVID-19 in Manaus 5 . However, the precise relationship between circulating SARS-CoV-2 variants and epidemic dynamics in Amazonas remains unclear due to the paucity of viral sequences sampled in this Brazilian state before December 2020. Results Evidence of successive SARS-CoV-2 lineage replacements in Amazonas.To acquire a more in-depth understanding of the genetic diversity of SARS-CoV-2 variants circulating in Amazonas state since the early epidemic, we generated 250 SARS-CoV-2 high-quality, whole-genome sequences from individuals living in 25 municipalities, between 16 March 2020 and 13 January 2021 (Fig. 1a,b). Viral sequences were generated at FIOCRUZ Amazônia, which is part of both the Amazonas state health genomics network (REGESAM) and the consortium FIOCRUZ COVID-19 Genomics Surveillance Network of the Brazilian Ministry of Health (http:// www.genomahcov.fiocruz.br/). Our genomic survey revealed that most sequences were classified into five lineages:

IMPORTANCECurrent guidelines recommend screening eye examinations for infants with microcephaly or laboratory-confirmed Zika virus infection but not for all infants potentially exposed to Zika virus in utero.OBJECTIVE To evaluate eye findings in a cohort of infants whose mothers had polymerase chain reaction-confirmed Zika virus infection during pregnancy.DESIGN, SETTING, AND PARTICIPANTS In this descriptive case series performed from January 2 through October 30, 2016, infants were examined from birth to 1 year of age by a multidisciplinary medical team, including a pediatric ophthalmologist, from Fernandes Figueira Institute, a Ministry of Health referral center for high-risk pregnancies and infectious diseases in children in Rio de Janeiro, Brazil.PARTICIPANTS Mother-infant pairs from Rio de Janeiro, Brazil, who presented with suspected Zika virus infection during pregnancy were referred to our institution and had serum, urine, amniotic fluid, or placenta samples tested by real-time polymerase chain reaction for Zika virus.MAIN OUTCOMES AND MEASURES Description of eye findings, presence of microcephaly or other central nervous system abnormalities, and timing of infection in infants with confirmed Zika virus during pregnancy. Eye abnormalities were correlated with central nervous system findings, microcephaly, and the timing of maternal infection. RESULTSOf the 112 with polymerase chain reaction-confirmed Zika virus infection in maternal specimens, 24 infants (21.4%) examined had eye abnormalities (median age at first eye examination, 31 days; range, 0-305 days). Ten infants (41.7%) with eye abnormalities did not have microcephaly, and 8 (33.3%) did not have any central nervous system findings. Fourteen infants with eye abnormalities (58.3%) were born to women infected in the first trimester, 8 (33.3%) in the second trimester, and 2 (8.3%) in the third trimester. Optic nerve and retinal abnormalities were the most frequent findings. Eye abnormalities were statistically associated with microcephaly (odds ratio [OR], 19.1; 95% CI, 6.0-61.0), other central nervous system abnormalities (OR, 4.

Background: The evidence base for the efficacy of cognitive behaviour therapy (CBT) for treating body dysmorphic disorder (BDD) is weak. Aims: To determine whether CBT is more effective than anxiety management (AM) in an outpatient setting. Method: This was a single-blind stratified parallel-group randomised controlled trial. The primary endpoint was at 12 weeks, and the Yale-Brown Obsessive Compulsive Scale for BDD (BDD-YBOCS) was the primary outcome measure. Secondary measures for BDD included the Brown Assessment of Beliefs Scale (BABS), the Appearance Anxiety Inventory (AAI) and the Body Image Quality of Life Inventory (BIQLI). The outcome measures were collected at baseline and week 12. The CBT group, unlike the AM group, had 4 further weekly sessions that were analysed for their added value. Both groups then completed measures at their 1-month follow-up. Forty-six participants with a DSM-IV diagnosis of BDD, including those with delusional BDD, were randomly allocated to either CBT or AM. Results: At 12 weeks, CBT was found to be significantly superior to AM on the BDD-YBOCS [β = -7.19; SE (β) = 2.61; p < 0.01; 95% CI = -12.31 to -2.07; d = 0.99] as well as the secondary outcome measures of the BABS, AAI and BIQLI. Further benefits occurred by week 16 within the CBT group. There were no differences in outcome for those with delusional BDD or depression. Conclusions: CBT is an effective intervention for people with BDD even with delusional beliefs or depression and is more effective than AM over 12 weeks.

IMPORTANCE Zika virus (ZIKV) is a mosquito-borne flavivirus recognized as teratogenic since the 2015 to 2016 epidemic. Antenatal ZIKV exposure causes brain anomalies, yet the full spectrum has not been delineated. OBJECTIVE To characterize the clinical features of ZIKV infection at a pediatric referral center in Rio de Janeiro, Brazil, among children with antenatal ZIKV exposure. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study conducted from May to July 2019 of a prospective cohort of 296 infants with antenatal ZIKV exposure followed up since December 2015 at a tertiary maternity-pediatric hospital. EXPOSURES Zika virus infection during pregnancy. MAIN OUTCOMES AND MEASURES Characterization of clinical features with anthropometric, neurologic, cardiologic, ophthalmologic, audiometric, and neuroimaging evaluations in infancy and neurodevelopmental assessments (Bayley Scales of Infant and Toddler Development, Third Edition) from 6 to 42 months of age, stratified by head circumference at birth (head circumference within the reference range, or normocephaly [NC] vs microcephaly [MC]). RESULTS Antenatal exposure to ZIKV was confirmed for 219 of 296 children (74.0%) referred to Instituto Fernandes Figueira with suspected ZIKV infection through positive maternal or neonatal polymerase chain reaction analysis or IgM serology results. Of these children, 110 (50.2%) were boys, ages ranged from 0 to 4 years, and 53 (24.2%) had congenital microcephaly. The anomalies observed in ZIKV-exposed children with MC or NC were failure to thrive (
