ABSTRACT
In 2021, the number of children who required PC for STH decreased for pre-SAC from 291.2 million to 260.6 million and for SAC from 732.3 million to 653.7 million (Figure 2). This change was mainly due to revision of the numbers of children who require PC for STH in India, which decreased from 103.5 to 80.7 million for pre-SAC and from 332.1 to 259.1 million for SAC. The decreases were based on impact assessment surveys conducted in the past few years, which changed the endemicity status of some districts. Globally, PC coverage of SAC increased from 47% in 2020 to 62.9% in 2021.The number of SAC reached with deworming increased almost to that before the COVID-19 pandemic (411 million in 2021, 344 million in 2020, 455.9 million in 2019), indicating that countries are recovering.
ABSTRACT
The possession of exotic animals as pets is a social practice that has become more visible in Mexico in recent years, so it is interesting to understand its environmental and social implications and those related to human health. The present study aims to identify the main species of exotic animals kept as pets and the zoonotic diseases reported in these species. We analyzed official figures of seizures of exotic fauna in Mexico and reviewed specialized literature on zoonotic diseases documented in Mexico in these species. We identified zoonoses in species of fauna that can be acquired legally and illegally in the country, reported in environments in which animals coexist with other species and are in direct contact with people, which represents an important factor in the spread and propensity of this type of disease. We conclude that the sanitary regulation of wildlife markets, the monitoring and studying microorganisms associated with wildlife are valuable strategies to prevent the emergence of zoonoses.
ABSTRACT
This paper describes the clinical signs and use of differential laboratory diagnostic techniques (computed tomography, cytology, histopathology, antigen/antibody detection and polymerase chain reaction) for infectious (viral, bacterial, fungal and parasitic) and non-infectious (inflammatory/immune mediated, neoplastic, cardiac, malformation, foreign body, smoke inhalation, aspiration of caustic material, non-cardiogenic, pulmonary oedema, traumativ, pneumothorax, pulmonary contusions and idiopathic) causes of respiratory diseases in cats and dogs in Ontario, Canada.
ABSTRACT
There are some doubts about the exact relationship between neglected infectious diseases (NIDs) and COVID-19 disease, which remains to be clearly defined. The present review summarized the effect of parasitic infections as the risk factors or protective agents in the COVID-19 pandemic. Parasites could proficiently modulate immune responses. Thus, parasitic infections could have a different impact on the incidence and clinical severity of COVID-19 in different regions of the world. Also, restoring programs to prevent, treat, and control NIDs, in particular helminths, could help in reducing the incidence and mortality of COVID-19 in endemic areas and help to increase vaccination effectiveness. Changes in the gut microbiome associated with helminth infection may have systemic immunomodulatory effects toward suppressing host immune responses, reducing vaccine efficacy and increasing the severity of other infectious diseases. The cytokine storm observed in severe cases of COVID-19 is characterized by a predominance of proinflammatory cytokines, such as IL-6. However, it is possible that helminth infection could change the outcome of infection by modifying the Th2 response to limit the inflammatory component;this would be particularly apparent in areas endemic for helminthic infections, which suggests a possible protective effect against COVID-19. Because parasitic infections affect more than 2 billion people throughout the world, their impact on COVID-19- associated effects on public health could be considerable. Further studies with larger sample sizes would be needed to explore the possible role of neglected parasitic infections in the COVID-19 pandemic.
ABSTRACT
This progress report provides an update on the progress made towards eliminating nnchocerciasis (river blindness) by the World Health Organization (WHO) as part of its road map on neglected tropical diseases for 2021-2030. The report highlights that the goal is to eliminate the need for mass drug administration of ivermectin in at least one focus in 34 countries by 2030, in more than 50% of the population in at least 16 countries and in the entire endemic population in at least 12 countries. However, challenges remain in achieving these goals, including incomplete mapping of all transmission zones, co-endemicity of onchocerciasis and loiasis, a potential decrease in sensitivity to ivermectin, uncoordinated cross-border work, suboptimal programme implementation and inadequate technical and financial resources. COVID-19 has also delayed national programmes, with millions of doses of preventive chemotherapy that should have been distributed expiring. The report also provides regional highlights, including that in 2021, 23 countries reported having treated a total of 142.3 million people for onchocerciasis, representing 58.1% of global coverage, and that the African region faces the greatest challenge with 99% of the global burden of the disease in this region.
ABSTRACT
Hydatid cyst is an infection caused by the parasite Echinococcus granulosus, which is seen endemic in animal husbandry areas. Due to the heavy burden on physicians during the pandemics, diseases other than COVID-19 took a back seat during the differential diagnosis of patients. Hydatid cyst is located in the bone at a rate of 1-4%. The symptoms and imaging features of the cyst located in the bone are not specific, thus they are less likely to be considered in the differential diagnosis of extremity lesions. The absence of a specific clinical picture and the lack of high sensitivity of the indirect hemagglutination test bring radiological evaluations to the fore in diagnosis. In this case report, we shared diagnostic and treatment process of a patient-who was first admitted to the hospital with edema, pain and fever in the leg, was diagnosed with multisystem inflammatory syndrome in children (MIS-C) later diagnosed hydatid cyst with lung and bone involvement.
ABSTRACT
This article provides a brief overview of the 31st meeting of the International TaskForce for Disease Eradication (ITFDE) that was convened at The Carter Center in Atlanta, GA, USA on 20-21 October 2020 to discuss "The impact of the COVID-19 pandemic on eradication and elimination programmes and the way forward." It highlights the results of 7 eradication programmes, with specific conclusions and recommendations for each: Guinea Worm Eradication Programme(dracunculiasis;GWEP);Global Polio Eradication Initiative (GPEI);elimination programmes for measles and rubella (MR), malaria, river blindness (onchocerciasis;RB), and lymphatic filariasis (LF);and the program for the Global Elimination of Trachoma.
ABSTRACT
This article describes how the COVID-19 pandemic significantly reduced provision of treatment in the Yanomami focus area (YFA) in 2020, especially in the Bolivarian Republic of Venezuela. The distribution of ivermectin for mass treatment (MDA) to prevent onchocerciasis was affected worldwide by the COVID-19 pandemic in 2020, as were MDA programs for other neglected tropical diseases (NTDs). On 1 April 2020, WHO recommended that mass treatment campaigns, active case-finding, and population-based surveys for NTDs be postponed until further notice to reduce the risk of COVID-19 transmission associated with large-scale community health interventions. The Carter Center, which provides major funding to MDA in the Bolivarian Republic of Venezuela, temporarily halted its activities in 2020 due to an administrative problem and, once the COVID-19 pandemic had taken hold, in order to adhere to WHO recommendations, its own policies, and the policies of other donor organizations. Ivermectin treatment continued to be offered in Brazil, supported by the government, with essential health services such as vaccination and malaria control. On 27 July 2021, WHO released new interim guidance for NTD programs. This included a risk-benefit analysis to figure out if activities could be resumed safely and detailed standards for reducing risk with all known precautions (such as wearing masks, socialdistance, hand sanitizing and/or handwashing, limiting live meetings and group size). The program in the Bolivarian Republic of Venezuela followed these instructions and made a plan to get back to work safely, which was what WHO wanted.
ABSTRACT
This article describes the Global Programme to Eliminate Lymphatic Filariasis (GPELF), which aims to stop the spread of infection by mass drug administration (MDA) and ease the suffering of patients through morbidity management and disability prevention (MMDP). In 2020, LFMDA treated 21.6 million 2-4-year-olds and 98.5 million 5-14-year-olds. Given the impact of LF MDA on soil-transmitted helminth (STH) infections, WHO advises adding STH infection assessment into transmission assessment surveys (TAS) to increase NTD intervention efficiency. Once preTAS and TAS standards are met, an IU's population no longer needs MDA. 692 million people didn't need MDA. This 49% decline in LF cases is a huge step toward meeting the Sustainable Development Goal (SDG). Thirteen countries and 171 IUs performed TASs in 2020. A total of 4316 TAS have been conducted in EUs, which are greater or smaller than IUs. 100% of EUs passed a TAS, according to 2020 reports (the proportion of children who tested positive for LF infection was below the threshold for considering transmission unsustainable). Several 2020 TAS were postponed because to COVID-19 pandemic restrictions. Despite a global epidemic, GPELF achieved progress in 2020, demonstrating the resolve and inventiveness of national LFprogrammes to end this illness.
ABSTRACT
In this report, four countries (Colombia, Ecuador, Guatemala, and Mexico) have completed the WHO-recommended process for verification of the interruption of human onchocerciasis transmission, and many others have ceased mass drug administration (MDA), completed post-treatment surveillance (PTS), or both in at least one transmission area on their territory. Interruption of transmission enabled governments to preserve the benefits acquired over many years of effective MDA with Ivermectin and to discontinue MDA permanently, thereby protecting populations living in endemic areas from morbidity and infection. The eradication of human onchocerciasis would contribute significantly to achieving Sustainable Development Goal (SDG) 3.3, which calls for the eradication of neglected tropical diseases (NTDs) by 2030. All countries endemic for onchocerciasis have reported instances of COVID-19. The impact of the pandemic on NTD interventions has been discussed elsewhere. In many countries, scheduled MDA rounds were postponed due to efforts to prevent the spread of SARS-CoV-2 in onchocerciasis-endemic nations. In 2020, 26.9% fewer patients were treated for onchocerciasis than in 2019. MDA was implemented in fewer nations and implementation units in 2020 (1096 versus 1538 in 2019), resulting in a 27.7% decrease in global geographical coverage. The WHO Global Health Observatory provides access to data submitted by governments.

ABSTRACT
Backyard poultry is evolving as a fast-growing sector in recent times across the world. Apart from providing nutritional security, and livelihood to marginalized sector, also fulfils the demand for organic and welfare meat and eggs. However, the productivity is often challenged by incidences of diseases due to poor biosecurity and lack of vaccination. In this study, systematic review and meta-analysis were performed on the global prevalence of infectious diseases in backyard chickens. A total of 22 bacterial, viral, parasitic and fungal diseases were reported from 55 publications between 2000 and 2020 worldwide. Viral diseases were the most reported followed by bacterial and parasitic diseases. 61 out of 91 studies from 55 publications investigated seven major diseases: Avian influenza (AI), Newcastle disease (ND), infectious bronchitis (IB), Mycoplasma gallisepticum (MG), Mycoplasma synoviae (MS), Salmonella infection, and infectious laryngotracheitis (ILT). The overall pooled prevalence estimate for all the diseases worldwide was 33% (95% confidence interval (CI): 28-38). The pooled estimates for most reported viral diseases AI and ND were 12.5% (95% CI: 7-18) and (30% CI: 19-43), respectively. IBD (71% CI: 13-100), MS (76% CI: 67-85) and helminth infestations (72% CI: 44-93) were the highly prevalent diseases among viral, bacterial and parasitic infections, respectively. The continent wise pooled prevalence ranged from 17 to 32%. The present results will help in devising the best possible strategies to minimize the disease risk for commercial poultry and humans as well as for improving the productivity of backyard poultry farming.

ABSTRACT
The growth and development of children is very important, as this would form the foundation for the quality of future generations in the nation. The slightest developmental disorders in infancy, if not detected and not handled properly will lead to a bad impact. Various genetic and environmental factors influence Toddler growth and development. Purpose: To distinguish the description of the risk factors related to child growth and development. Method: This research uses quantitative method. The design of the research is based on a cross-sectional approach in the analysis survey design. In the study, all toddlers under 59 month old were collected using a total of 366 samples in 2020 at the Ngalang Village, Gedangsari public health center and Gunungkidul Regency. Data analysis used univariate analysis of frequency distribution.
ABSTRACT
This article is a 2021 update on the WHO report on the impact of COVID-19 on neglected tropical diseases (NTD) and the response appropriated by the WHO. In January 2021, and after almost 2 years of wide-ranging consultations, WHO launched the new NTD roadmap for 2021-2030 that provides a framework and actions to drive progress towards a world free of NTDs, contributing during this decade to the attainment of the United Nations Sustainable Development Goals through: fundamental shifts that put countries, communities and people at the centre of the agenda;supportive cross-sectoral actions, such as health, education, nutrition, water, sanitation, and hygiene and;sustaining and accelerating progress towards the 2030 goals. Furthermore, the roadmap provides opportunities to evaluate, assess, and adjust programmatic actions, as and when needed, over the next decade by setting clear targets and milestones. Another distinct feature of this roadmap is to drive greater ownership by national and local governments, including communities. The overarching 2030 global targets are to: (1) reduce by 90% the number of people requiring interventions against NTDs;(2) have at least 100 countries having eliminated at least one NTD;(3) eradicate 2 diseases (dracunculiasis and yaws) and;(4) reduce by 75% the DALYs related to NTDs. The roadmap will enable future measuring of progress towards eradication, elimination and control of the 20 NTDs by tracking disease-specific targets. Additionally, the roadmap includes 10 cross-cutting targets relevant to progress in the areas of integration, multisectoral coordination, universal health coverage, and country ownership. Examples include a reduction by more than 75% in the number of deaths from vector-borne NTDs such as dengue and leishmaniasis;100% access to basic water supply, sanitation, and hygiene in areas endemic for NTDs;75% integrated treatment coverage index for preventive chemotherapy;90% countries including NTDs in their package of essential services, and 90% countries collecting and reporting NTD data disaggregated by gender.

In October 2021 (from 00: 00, 1 October to 24: 00, 31 October), a total of 523 006 cases of notifiable communicable diseases, including 2 040 deaths, were reported in China (except Hong Kong, Macao Special Administrative Regions and Taiwan Province, the same below). In communicable diseases in class A, 2 cases of cholera were reported without death. In communicable diseases in class B, no cases and no deaths of severe acute respiratory syndrome, poliomyelitis, human infection with highly pathogenic avian influenza virus, diphtheria and human infection with avian influenza A (H7N9) virus were reported. For the remaining 22 communicable diseases in class B, 249 605 cases were reported, a decrease of 8% compared with last month (272 332 cases) and a decrease of 3% compared with the same period in 2020 (258 591 cases). The first 5 diseases in terms of reported case number were viral hepatitis, pulmonary tuberculosis, syphilis, gonorrhea and AIDS, accounting for 95% of the total reported cases in class B. A total of 2 039 deaths were reported, a decrease of 6% (133 deaths) compared with last month (2 172 deaths) and an increase of 17% compared with the same period in 2020 (1 737 deaths). According to the website of the National Health Commission of China, a total of 1 081 confirmed COVID-19 cases were reported, without death, by 31 provinces (municipalities, autonomous regions) and Xinjiang Production and Construction Corps from 00: 00, 1 October to 24: 00, 31 October, 2021. In class C communicable diseases, a total of 273 399 cases were reported, an increase of 20% compared with last month (228 597 cases) and a decrease of 13% compared with the same period in 2020 (315 366 cases). The first 3 diseases in terms of reported case number were hand foot and mouth disease (HFMD), other infectious diarrhea and influenza, accounting for 95% of the total reported cases in class C.
