    This study aimed to describe the epidemiological and clinical characteristics of endemics of two rickettsial diseases, scrub typhus (ST) and Japanese spotted fever (JSF), in Japan.

    We conducted a retrospective, descriptive epidemiological assessment of cases notified via national surveillance from 2007-2016.

    Over the 10-year period, 4185 ST and 1765 JSF cases were notified; of these, 20 (0.48%) cases of ST and 16 (0.91%) cases of JSF were fatal at the time of reporting. The elderly had higher notification rates and fatalities. While the annual number of ST notifications was stable and cases were reported from a broad geographic range, the number of JSF reports increased three-fold, expanding from the southwest to the east. The seasonality of ST varied by region and was more common during spring/summer in the north and autumn/winter in the south; 78% of cases occurred during autumn/winter, mainly in the southern region. Most of the fatal ST cases occurred in the spring/summer and occurred in the northern region.

    Our analysis identified seasonal and regional variations in the distribution of rickettsiosis. These variations were most likely to be related to the ecology of the vectors and etiological agents. Knowing the recent epidemiological and clinical features of ST and JSF can support clinical diagnosis and guide preventative activities against these vector-borne diseases.

    Little is known regarding the developmental consequences of congenital Zika syndrome (CZS) without microcephaly at birth. Most previously published clinical series were descriptive and they had small sample sizes.

    We conducted a cohort study to compare the growth, clinical, and motor development outcomes for 110 children with CZS born with and without microcephaly up to their third birthday. Ninety-three had their head circumference (HC) at birth abstracted and they did not have hypertensive hydrocephalus at birth, where 61 were born with microcephaly and 32 without.

    The HC z-scores decreased steeply from birth to six months of age, i.e., from -3.77 to -6.39 among those with microcephaly at birth and from -1.03 to -3.84 among those without. Thus, at 6 months of age, the mean HC z-scores for children born without microcephaly were nearly the same as those for children born with microcephaly. Children born without microcephaly were less likely to have brain damage, ophthalmic abnormalities, and drug-resistant epilepsy, but the differences in many conditions were not statistically significant.

    Children born without microcephaly were only slightly less likely to present severe neurologic impairment and to develop postnatal-onset microcephaly, and some of the original differences between the groups tended to dissipate with age.

However, to obtain lower respiratory specimens from bronchoscopy with bronchoalveolar lavage (BAL) is necessary to confirm COVID-19 or other diagnosis that will change clinical management. We report a case of diagnostic difficulty with five negative SARS-CoV-2 RT-PCR testing in four upper respiratory tract and one stool samples following presentation with fever during the quarantine period and a strong epidemiological linkage to an index patient with COVID-19. read more The final diagnosis was confirmed by BAL. Special precautions to be taken when performing bronchoscopy in high-risk non-intubated patients were discussed.

    This article is one of a series on acute, severe diseases of humans caused by emerging viruses for which there are no or limited licensed medical countermeasures. We approached this summary on South American Hemorrhagic Fevers (SAHF) from a clinical perspective that focuses on pathogenesis, clinical features, and diagnostics with an emphasis on therapies and vaccines that have demonstrated potential for use in an emergency situation through their evaluation in nonhuman primates (NHPs) and/or in humans.

    A standardized literature review was conducted on the clinical, pathological, vaccine, and treatment factors for SAHF as a group and for each individual virus/disease.

    We identified 2 treatments and 1 vaccine platform that have demonstrated potential benefit for treating or preventing infection in humans and 4 other potential treatments currently under investigation.

    We provide succinct summaries of these countermeasures to give the busy clinician a head start in reviewing the literature if faced with a patient with South American Hemorrhagic Fever. We also provide links to other authoritative sources of information.

    To determine the prevalence and associated factors of diabetes mellitus (DM) among tuberculosis (TB) cases in Brunei Darussalam.

    We conducted a retrospective cohort study among all TB patients registered between 2013 and 2018. Collected data include sociodemographics, comorbidities, and information related to their TB diagnosis and treatment outcomes. Associated factors of having DM among TB patients were investigated using logistic regression analyses.

    We identified a total of 1362 TB patients, among which 462 (33.9% ) also have DM. 70.6% (n = 326) were diagnosed with DM at least six months prior to their TB diagnosis. The incidence of newly diagnosed DM among TB patients was 74.2 per 1000 population. Significant factors of having TB and DM comorbidity were age (adjusted OR (adj. OR) = 1.04 ), classified as smear-positive pulmonary TB (adj. OR = 5.77 ), having the following underlying conditions hypertension/heart disease (adj. OR = 24.05 [95%CI 5.80,100.
