Furthermore, of the 811 deaths registered, 381 had the gender identified, 77.4% (n=295) were males, and 22.6% (n=86) were females. Conclusion: given the findings of this study, it is understood that the epidemiological situation of the disease requires joint actions by epidemiological and environmental surveillance in order to develop prevention and control measures based on one health perspective.

No Evidence of Rabies Exposure in Wild Marmosets (Callithrix jacchus) of Northeast Brazil.

Rabies transmitted by wildlife is the main source of human rabies mortality in Latin America and considered an emerging disease. The common marmoset Callithrix jacchus of Brazil is the only known primate reservoir of rabies worldwide. We tested whether alive free-ranging C. jacchus were exposed to rabies in four northeast states that have previously reported rabies-positive dead C. jacchus (Pernambuco and Bahia) or not (Paraíba and Rio Grande do Norte). Our results show no evidence of rabies antibodies or infection in the sampled C. jacchus, suggesting that apparently healthy marmosets are not widely exposed to rabies over their natural range.

Description of human anti-rabies post-exposure prophylaxis care notifications in Brazil, 2014-2019. / Descrição das notificações de atendimento antirrábico humano para profilaxia pós-exposição no Brasil, 2014-2019.

OBJECTIVE: To analyze human anti-rabies post-exposure prophylaxis notifications in Brazil. METHODS: This was a descriptive study using data from the Notifiable Diseases Information System in Brazil, from 2014 to 2019. RESULTS: A total of 4,033,098 anti-rabies medical consultations were notified, averaging 672,183 a year. Percentage care was higher among males (n = 2,111,369; 52.4%), those under 19 years old (n = 1,423,433; 35.3%), living in urban areas (n = 3,386,589; 88.1%), attacked by dogs (n = 3,281,190; 81.5%) and bitten (n = 3,575,717; 81.9%), mainly on the hands and feet (n = 1,541,201; 35.3%). The most frequent prophylactic procedure was observation plus vaccination (n = 1,736,036; 44.2%). Prophylactic procedure was appropriate in 57.8% (n = 2,169,689) of cases and inappropriate in 42.2% (n = 1,582,411) of cases. CONCLUSION: Although there were appropriate prophylactic procedures, we also found procedures that were inappropriate and which, when insufficient, can result in cases of human rabies and, when unnecessary, can result in waste, including shortage of immunobiological products.

Spatio-temporal dynamics of rabies and habitat suitability of the common marmoset Callithrix jacchus in Brazil.

Rabies transmitted by wildlife is now the main source of human rabies in the Americas. The common marmoset, Callithrix jacchus, is considered a reservoir of rabies causing sporadic and unpredictable human deaths in Brazil, but the extent of the spillover risk to humans remains unknown. In this study, we described the spatiotemporal dynamics of rabies affecting C. jacchus reported to Brazil's Ministry of Health passive surveillance system between 2008 and 2020, and combined ecological niche modelling with C. jacchus occurrence data to predict its suitable habitat. Our results show that 67 outbreaks (91 cases) of rabies affecting C. jacchus were reported by 41 municipalities between January 2008 and October 2020, with a mean of 5 outbreaks/year [range: 1-14]. The maximum number of outbreaks and municipalities reporting cases occurred in 2018, coinciding with higher surveillance of primate deaths due to Yellow Fever. A mean of 3 [1-9] new municipalities reported outbreaks yearly, suggesting potential spatial expansions of the C. jacchus variant in northeastern Brazil and emerging rabies spillover from vampire bat Desmodus rotundus to C. jacchus in the north and south. Outbreaks were concentrated in the states of Ceará (72%) and Pernambuco (16%) up to 2012, but are now reported in Piauí since 2013, in Bahia since 2017 (D. rotundus' antigenic variant, AgV3) and in Rio de Janeiro since 2019 (AgV3). Besides confirming suitable habitat for this primate in the northeast and the east coast of Brazil, our Maximum Entropy model also predicted suitable habitat on the north and the west states of the country but predicted low habitat suitability among inland municipalities of the Caatinga biome reporting rabies. Our findings revealed new areas reporting rabies infecting C. jacchus, highlighting the need to implement strategies limiting spillover to humans and to better understand the drivers of C. jacchus rabies dynamics.

Strengthening therapeutic adherence and pharmacovigilance to antimalarial treatment in Manaus, Brazil: a multicomponent strategy using mHealth.

BACKGROUND: Public health initiatives for improving adherence to primaquine based regimens and enhancing effective pharmacovigilance are needed to support the efforts for malaria elimination in real world conditions. METHODS: A multicomponent patient-oriented strategy using a Smart Safety Surveillance (3S) approach including: (1) educational materials for treatment counselling and identification of warning symptoms of haemolytic anaemia; (2) an mHealth component using Short Message Service (SMS) treatment reminders and (3) development and implementation of follow-up phone surveys three days after treatment completion, using a web-based platform linked to the local information system of malaria. Adherence was measured using the Morisky Medication Adherence Scale. Self-reported events were registered using a structured questionnaire and communicated to the Brazilian Health Regulatory Agency. RESULTS: Educational materials were disseminated to 5594 patients, of whom 1512 voluntarily entered the mHealth component through the local information system; 7323 SMS were sent, and 1062 participants completed a follow-up survey after treatment. The mean age of patients was 37.36 years (SD 13.65), 61.24% were male, 98.54% were infected with. Plasmodium vivax and 95.90% received a short regimen of chloroquine plus primaquine (CQ + PQ 7 days), as per malaria case management guidelines in Brazil. From the 1062 surveyed participants 93.31% were considered adherent to the treatment. Most of the patients (95.20%) reported at least one adverse event. Headache, lack of appetite and nausea/vomiting were the most frequently reported adverse events by 77.31%, 70.90% and 56.78% of the patients respectively. A quarter of the patients reported anxiety or depression symptoms; 57 (5.37%) patients reported 5 to 6 warning symptoms of haemolytic anaemia including jaundice and dark urine in 44 (4.14%). Overall, three patients presenting symptoms of haemolytic anaemia attended a hospital and were diagnosed with G6PD deficiency, and one had haemolysis. All of them recovered. CONCLUSIONS: Under real world conditions, a multicomponent patient-oriented strategy using information and communication technologies allowed health care providers to reinforce treatment adherence and enhance safety surveillance of adverse events associated with regimens using primaquine. Active monitoring through phone surveys also reduced under-reporting of ADRs. This approach is low-cost, scalable and able to support prioritized activities of the national malaria programme.

Association and birth prevalence of microcephaly attributable to Zika virus infection among infants in Paraíba, Brazil, in 2015-16: a case-control study.

BACKGROUND: In 2015, the number of infants born with microcephaly increased in Paraíba, Brazil, after a suspected Zika virus outbreak. We did a retrospective case-control investigation to assess the association of microcephaly and Zika virus. METHODS: We enrolled cases reported to the national database for microcephaly and born between Aug 1, 2015, and Feb 1, 2016, on the basis of their birth head circumference and total body length. We identified controls from the national birth registry and matched them to cases by location, aiming to enrol a minimum of two controls per case. Mothers of both cases and controls were asked about demographics, exposures, and illnesses and infants were measured at a follow-up visit 1-7 months after birth. We took blood samples from mothers and infants and classified those containing Zika virus IgM and neutralising antibodies as evidence of recent infection. We calculated prevalence of microcephaly and odds ratios (ORs) using a conditional logistic regression model with maximum penalised conditional likelihood, and combined these ORs with exposure probability estimates to determine the attributable risk. FINDINGS: We enrolled 164 of 706 infants with complete information reported with microcephaly at birth, of whom we classified 91 (55%) as having microcephaly on the basis of their birth measurements, 36 (22%) as small, 21 (13%) as disproportionate, and 16 (10%) as not having microcephaly. 43 (26%) of the 164 infants had microcephaly at follow-up for an estimated prevalence of 5·9 per 1000 livebirths. We enrolled 114 control infants matched to the 43 infants classified as having microcephaly at follow-up. Infants with microcephaly at follow-up were more likely than control infants to be younger (OR 0·5, 95% CI 0·4-0·7), have recent Zika virus infection (21·9, 7·0-109·3), or a mother with Zika-like symptoms in the first trimester (6·2, 2·8-15·4). Once Zika virus infection and infant age were controlled for, we found no significant association between microcephaly and maternal demographics, medications, toxins, or other infections. Based on the presence of Zika virus antibodies in infants, we concluded that 35-87% of microcephaly occurring during the time of our investigation in northeast Brazil was attributable to Zika virus. We estimate 2-5 infants per 1000 livebirths in Paraíba had microcephaly attributable to Zika virus. INTERPRETATION: Time of exposure to Zika virus and evidence of infection in the infants were the only risk factors associated with microcephaly. This investigation has improved understanding of the outbreak of microcephaly in northeast Brazil and highlights the need to obtain multiple measurements after birth to establish if an infant has microcephaly and the need for further research to optimise testing criteria for congenital Zika virus infection.

Outbreak of Guillain-Barré syndrome possibly related to prior Zika virus infection, Metropolitan Region of Recife, Pernambuco, Brazil, 2015. / Surto de síndrome de Guillain-Barré possivelmente relacionado à infecção prévia pelo vírus Zika, Região Metropolitana do Recife, Pernambuco, Brasil, 2015.

OBJETIVO: to investigate the occurrence of GBS in the Metropolitan Region of Recife, PE, Brazil, 2015. METHODS: this was a descriptive study using data from the Hospital Information System, National Pharmaceutical Services Management System and interviews; GBS cases were classified according to Brighton criteria and prior infection according to laboratory and clinical criteria. RESULTS: in 2015, the number of GBS hospitalizations had a threefold increase in comparison to 2014. We investigated 44 confirmed or probable GBS cases, of which 18 had symptoms of Zika infection up to 35 days before the occurrence of GBS, mainly rash; one case was laboratory-confirmed for Zika virus infection and one death was registered. CONCLUSION: the findings reinforce a possible relationship between GBS and Zika infection, given the absence of increased GBS occurrence in previous dengue epidemic years, absence of chikungunya transmission records, presence of clinical manifestations compatible with infection and a laboratory confirmation.

Microcephaly in Piauí, Brazil: descriptive study during the Zika virus epidemic, 2015-2016. / Microcefalia no Piauí, Brasil: estudo descritivo durante a epidemia do vírus Zika, 2015-2016.

OBJECTIVE: to describe the occurrence and characteristics of microcephaly cases in Piauí, Brazil, during an epidemic of Zika virus infection in 2015-2016.
