Bat-associated bartonellae, including Bartonella mayotimonensis and Candidatus Bartonella rousetti, were recently identified as emerging and potential zoonotic agents, respectively. However, there is no report of bat-associated bartonellae in Zambia. Thus, we aimed to isolate and characterize Bartonella spp. from bats and bat flies captured in Zambia by culturing and PCR. Overall, Bartonella spp. were isolated from six out of 36 bats (16.7%), while Bartonella DNA was detected in nine out of 19 bat flies (47.3%). Subsequent characterization using a sequence of five different genes revealed that three isolates obtained from Egyptian fruit bats (Rousettus aegyptiacus) were Ca. B. rousetti. The isolates obtained from insectivorous bats (Macronycteris vittatus) were divided into two previously unclassified bat-associated bartonellae. A phylogenetic analysis of the six genotypes of Bartonella gltA sequences from nine pathogen-positive bat flies revealed that three genotypes belonged to the same clades as bat-associated bartonellae, including Ca. B. rousetti. The other three genotypes represented arthropod-associated bartonellae, which have previously been isolated only from ectoparasites. We demonstrated that Ca. B. rousetti is maintained between bats (R. aegyptiacus) and bat flies in Zambia. Continuous surveillance of Bartonella spp. in bats and serological surveys in humans in Africa are warranted to evaluate the public health importance of bat-associated bartonellae.

We have developed a probabilistic model to quantify the risks of COVID-19 explosion in Brazil, the epicenter of COVID-19 in Latin America. By explosion, we mean an excessive number of new infections that would overload the public health system. We made predictions from July 12th to Oct 10th, 2020 for various containment strategies, including business as usual, stay at home (SAH) for young and elderly, flight restrictions among regions, gradual resumption of business and the compulsory wearing of masks. They indicate that: if a SAH strategy were sustained, there would be a negligible risk of explosion and the public health system would not be overloaded. For the other containment strategies, the scenario that combines the gradual resumption of business with the mandatory wearing of masks would be the most effective, reducing risk to considerable category. Should this strategy is applied together with the investment in more Intensive Care Unit beds, risk could be reduced to negligible levels. A sensitivity analysis sustained that risks would be negligible if SAH measures were adopted thoroughly.

The Impact

Pollution  represents  a  problem  common  to economy and  public  health. Indeed, the public health, because of the  divers’  type of pollutions, is facing divers challenges for which urgent solutions are required.The biology provides approaches not only to deal with the pollution, but also to  obtain  economic  benefits. Some living  organisms  have  particular metabolisms  that allow  them  to  assimilate  and  metabolite  the polluting agents  and thus reduce the  impact  they have on both environment  and public health.  On  the other  hand,  the  metabolic  properties  of  specific organisms make  the  polluting  elements raw materials to  synthesize  other elements that are benefits  for  economy  and  non-toxic  for  the  ecology and  the  biohealth. Yet, other options such as the regulations and laws are  required  to improve the efficiency of these approaches.

Anthropological Fieldwork

Relations within are quintessential in anthropological fieldwork — and in archipelagos in particular. The domestic sea is incorporated in the national consciousness connecting an archipelagic nation but distinguishing individual islands with a strong emphasis on the centre. The Maldivian archipelago displays this spatial organization of a socio-political and economic centre and a dependent island periphery. In the national consciousness, the capital island, Male', contrasts with “the islands” — a distinction which is particularly evident in the public health sphere, where striving for health equity encounters geographical and socio-political obstacles. Using the topic of the inherited blood disorder thalassaemia as a magnifying lens, this paper asks how different actors are making sense of health inequities between central and outer islands in the Maldivian archipelago. Intra-archipelagic and international mobilities add to the complexities of topological relations, experiences, and representations within this multi-island assemblage. Yet, my study of archipelagic health relations is not confined to a mere outside look at the construction of the ‘island other’ within the archipelagic community. It is a situated investigative gaze on disjunctures, connections, and entanglements, reflecting my methodological-theoretical attempt to unravel my own involvement in island–island relations and representations — my being entangled while investigating entanglements.

AbstractFrom January 2015 to December 2018, 213 norovirus outbreaks with 3,951 patients were reported in Jiangsu, China. Based on viral RdRp and VP1 genes, eight genotypes, GII.2[P16] (144, 67.6%), GII.3[P12] (21, 9.9%), GII.6[P7] (5, 2.3%), GII.14[P7] (4, 1.9%), GII.4 Sydney[P31] (3, 1.4%), GII.1[P33] (1, 0.5%), GII.2[P2] (3, 1.4%), and GII.17[P17] (16, 7.5%) were identified throughout the study period. These genotypes were further regrouped as GII.R (Recombinant) and GII.Non-R (Non-recombinant) strains. In this report we showed that GII.R strains were responsible for at least 178 (83.6%) of 213 norovirus-positive outbreaks with a peak in 2017 and 2018. Most norovirus outbreaks occurred in primary schools and 94 of 109 (86.2%) outbreaks in primary schools were caused by GII.R, while GII.Non-R and GII.NT (not typed) strains accounted for 6 (5.5%) and 9 (8.3%) norovirus outbreaks, respectively. The SimPlot analysis showed recombination breakpoints near the ORF1/2 junction for all six recombinant strains. The recombination breakpoints were detected at positions varying from nucleotides 5009 to 5111, localized in the ORF1 region for four strains (GII.2[P16], GII.3[P12], GII.6[P7], and GII.14[P7]) and in the ORF2 region for the other (GII.4 Sydney[P31] and GII.1[P33]). We identified four clusters, Cluster I through IV, in the GII.P7 RdRp gene by phylogenetic analysis and the GII.14[P7] variants reported here belonged to Cluster IV in the RdRp tree. The HBGA binding site of all known GII.14 strains remained conserved with several point mutations found in the predicted conformational epitopes. In conclusion, gastroenteritis outbreaks caused by noroviruses increased rapidly in the last years and these viruses were classified into eight genotypes. Emerging recombinant noroviral strains have become a major concern and challenge to public health.

The causes of death in children under five years were studied using a structured verbal autopsy questionnaire. Possible determinants of death were also investigated. About 44% of deaths were among neonates [below 28 days of age] ; the major causes of death in neonates were prematurity [33%] and birth-related factors [30%]. In infants [1-11 months of age], the leading cause of death was congenital malformations [24%]. Accidents were responsible for one-third of deaths in children aged 1-4 years. Factors that might have contributed to death were investigated. The public health importance of causes of death was evaluated and its implications were discussed

The Public Health Laboratory Network had its inaugural meeting on 26 June 1997. The meeting was chaired by Professor Lyn Gilbert who played a pivotal role in establishing this group. This was the first time that all the state and territory public health laboratory directors had been called to meet together. Members expressed a strong desire to communicate more closely on issues of public health importance and recognised the importance of promoting the role of public health laboratories in outbreak investigations and routine and enhanced surveillance.

When James Olcott spoke before Connecticut farmers for “anti-stream pollution,” he urged the public to mobilize to stop water pollution by “ignorant or reckless capitalists.” In identifying the “ignorant and reckless capitalists,” Olcott focused the attention of the farmers on industrial waste and the role of manufacturers in their search for profits in causing pollution. Although manufacturers and the courts argued that industrialization brought wealth and prosperity to New England and hence was a general good, Olcott challenged this idea. He saw the issue as a conflict between industrialization and its costs on the one hand and the public good on the other. Concern over industrial pollution and the potential conflict between it and public health had already arisen in Massachusetts. Although the Massachusetts State Board of Health realized that the interests of the “capitalists” and those of the public health officials might be in conflict, in 1872 it hoped that with improved knowledge, “a way will be eventually found to joining them into harmonious relations,” much as Lyman believed science and technology would resolve the conflict between fishers and mill owners. The board's interest in “harmonious relations” also reflected a realization that at least for the last several years, the courts had seen pollution as an inevitable consequence of civilization and had been favorable toward industrialists, especially if no obvious alternative to dumping pollution existed. In 1866, William Merrifield sued Nathan Lombard because Lombard had dumped “Vitriol and other noxious substances” into the stream above Merrifield's factory, “corrupting” the water so badly that it destroyed his boiler. Chief Justice Bigelow ruled that Lombard had invaded Merrifield's rights. “Each riparian owner,” the judge wrote, “has the right to use the water for any reasonable and proper purpose. . . . An injury to the purity or quality of the water to the detriment of the other riparian owners, constitutes in legal effect, a wrong.” In 1872, Merrifield again went to court, claiming the City of Worcester regularly dumped sewage into Mill Brook, by which the waters became greatly corrupted and unfit to use.”
