BACKGROUND

Mpox, a zoonotic disease identified in central Africa in 1958, is mainly endemic to the Congo basin and West Africa. Collecting demographic and clinical data is crucial for early recognition and differentiation of skin lesions as the Philippines addresses this public health challenge.

We describe the demographics, clinical profile, and outcomes of suspected and confirmed mpox cases in the Philippines from July to November 2022.

This case series reviewed suspected and confirmed mpox cases at the Research Institute for Tropical Medicine from July to November 2022. Clinical data, demographics, and outcomes were collected through retrospective chart reviews and summarized using descriptive statistics.

Fifteen cases were reviewed, including 2 confirmed mpox cases, with an average age of 37.8 years and 80% male. The other symptoms associated with rash at presentation included fever (20%) followed by lymphadenopathy, malaise and chills reported in 1 case each. All patients had pustules and erythematous papules, with 67% showing vesicles. Lesions mainly appeared on the extremities (93%), trunk (60%), and head/neck (47%), evolving into crusts within 1–2 days. Non-confirmed cases were often misdiagnosed as varicella (60%), arthropod bites (20%), or folliculitis (7%).

Young to middle-aged males with travel histories were common in suspected and confirmed mpox cases. Lesions typically included papules and pustules on the extremities, evolving into crusts and erosions within 1–2 days. Confirmed cases had umbilicated papules and fever, while PCR-negative cases were diagnosed with local skin conditions. Testing is vital for timely detection and management, especially since mpox resembles other conditions.

Four organizations, including the Food and Agriculture Organization of the United Nations, the United Nations Environment Programme, WHO, and the World Organization for Animal Health, recently launched a new One Health Joint Plan of Action (2022-2026) which was the first time that the Quadripartite had issued a joint action plan on One Health. The action plan aimed to address the health challenges in the human, animal, plant, and environment, focusing on improving capabilities in six action tracks including One Health capacities, emerging and re-emerging zoonotic diseases, neglected tropical and vector-borne diseases, food safety, antimicrobial resistance and environment. This introduction will give an overview and brief translation of the background, content, and the plan's value, to help readers understand the joint action plan quickly.

Monkeypox is a zoonosis caused by monkeypox virus. Monkeypox was endemic mainly in central and western Africa in the past. Since May 7, 2022, monkeypox outbreaks have been reported in many non-epidemic countries and regions around the world. As of December 25, 2022, monkeypox cases have been detected in 110 countries and areas. Moreover, human to human transmission, especially among men who have sex with men, has aroused high global concern. The incidence, transmission route and clinical characteristics of monkeypox in 2022 seemed different from those in the past. Therefore, this paper summarizes the progress in research of the changes of epidemiological characteristics of monkeypox, the clinical characteristics of monkeypox and its prevention and treatment to provide scientific evidence for the prevention and control of monkeypox.

Echinococcosis is a zoonotic parasitic disease caused by infection with Echinococcus species. As the drug of first choice for treatment of echinococcosis, albendazole suffers from problems of large doses and remarkable adverse reactions in clinical therapy. Development of novel drugs against echinococcosis is of urgent need. Recently, great advances have been achieved in the research on traditional Chinese medicine for treatment of echinococcosis. This review summarizes the progress of researches on traditional Chinese medicine for treatment of echinococcosis, aiming to provide insights into development of anti-echinococcosis drugs.

Monkeypox is a zoonosis caused by monkeypox virus. Monkeypox virus belongs to the Orthopoxviruses genus in the Poxviridae family, which is regarded as the most important Orthopoxvirus infection in human beings after the extinction of smallpox. Since the first human monkeypox case was reported in the Democratic Republic of the Congo in 1970, monkeypox has become endemic in Central and West African. From May 6 to July 15, 2022, monkeypox has broken out in many countries. Monkeypox cases have been detected in 62 countries and regions. Moreover, human to human transmission has occurred and attracted high global attention. Monkeypox virus has been discovered for more than 60 years, but the understanding and research of its natural host, epidemiological characteristics and treatment are still relatively limited. Therefore, this study analyzes the epidemic situation, the possible causes of the outbreak and the future key research directions, and puts forward countermeasures to provide scientific basis for the prevention and control of monkeypox.

Nipah virus disease (NVD) is a newly emerged zoonosis with a case fatality rate of 40%-75%. NVD is a severe threat to human health and the development of livestock farming. NVD has become one of the emerging infectious diseases with great concern globally during more than 20 years. Nipah virus (NiV) is a pathogen for NVD, the natural host of which is Fruit bats of the Pteropodidae family. The clinical spectrum of NiV infection is broad, including asymptomatic infection, acute respiratory infection, fatal encephalitis, and even death. Since NiV was first identified in Malaysia in 1999, it has been prevalent mainly in Southeast Asia and South Asia. NiV is primarily transmitted to humans through bat-pig-human, contaminated food. Currently, there are no specific therapeutic drugs and vaccines for NVD. Although there are no cases of NVD reported in China, which has close personnel and trade exchanges with major NVD-endemic countries, and NiV antibody has also been detected in relevant bats. There is a potential risk of importing NVD and domestic outbreaks in the future in this country. This paper provides a systematic review of the research progress in the prevention and control of NVD etiology, epidemiology, clinical manifestations and laboratory diagnosis to help relevant staff to understand NVD more comprehensively and systematically.

Aims: Respiratory tract infections (RTIs) among Malaysian pilgrims are caused by exposure to zoonotic-potential respiratory pathogens, symptomatically and asymptomatically affected by rigorous pilgrimage rituals, overcrowding and other stressors. This study aimed to determine the prevalence, virulence and antibiotic resistance genes of selected zoonotic respiratory pathogens using polymerase chain reaction (PCR) assays among Hajj pilgrims from Kelantan state, Malaysia. Methodology and results: Throat swab specimens were obtained from 189 Kelantan Hajj pilgrims in 2016 and examined by PCR for the identification of respiratory pathogens. Thirteen samples (6.88%) were positive for Streptococcus pneumoniae and four (2.11%) were positive for Klebsiella pneumoniae. All the samples were negative for Influenza A virus, MERS-CoV and Mycobacterium bovis. One sample was positive for S. pneumoniae virulence lytA gene. One sample was positive for K. pneumoniae virulence magA and K2A genes respectively, and three samples were positive for K. pneumoniae rmpA genes. Ten and seven samples were positive for S. pneumoniae mefA and pbpA antibiotic resistance genes respectively. Two samples were positive for K. pneumoniae blaKPC and blaOXA-48 antibiotic resistance genes. Conclusion, significance and impact of study This work provided insight into the existence of zoonotic respiratory pathogens inducing Hajj RTIs in Kelantan pilgrims. It showed promising findings for zoonotic studies in Hajj settings. The findings could be relevant in potential control measures for the management of zoonotic infections among Hajj pilgrims.

Hydatid disease is a zoonotic infection in humans. The disease is endemic in some parts of the world, including Africa, Australia, and Asia, where cattle grazing is common; the disease is spread by an enteric route following the consumption of food contaminated with the eggs of the parasite. Failure to identify this parasite results in delayed diagnosis and increased morbidity to the patient. Upon diagnosis, every possible step should be taken, both surgical and medical, to prevent anaphylactic reactions from the cystic fluid. Postsurgical long-term follow up along with periodical ultrasonography of the liver and computed tomography scan of the abdomen is essential to rule out possible recurrence.

Toxoplasmosis is a cosmopolitan zoonotic infection, caused by a unicellular protozoan parasite known as Toxoplasma gondii that belongs to the phylum Apicomplexa. It is estimated that over one-third of the world's population has been exposed and are latently infected with the parasite. In humans, toxoplasmosis is predominantly asymptomatic in immunocompetent persons, while among immunocompromised individuals may be cause severe and progressive complications with poor prognosis. Moreover, seronegative pregnant mothers are other risk groups for acquiring the infection. The life cycle of T. gondii is very complex, indicating the presence of a plurality of antigenic epitopes. Despite of great advances, recognize and construct novel vaccines for prevent and control of toxoplasmosis in both humans and animals is still remains a great challenge for researchers to select potential protein sequences as the ideal antigens. Notably, in several past years, constant efforts of researchers have made considerable advances to elucidate the different aspects of the cell and molecular biology of T. gondii mainly on microneme antigens, dense granule antigens, surface antigens, and rhoptry proteins (ROP). These attempts thereby provided great impetus to the present focus on vaccine development, according to the defined subcellular components of the parasite. Although, currently there is no commercial vaccine for use in humans. Among the main identified T. gondii antigens, ROPs appear as a putative vaccine candidate that are vital for invasion procedure as well as survival within host cells. Overall, it is estimated that they occupy about 1%–30% of the total parasite cell volume. In this review, we have summarized the recent progress of ROP-based vaccine development through various strategies from DNA vaccines, epitope or multi epitope-based vaccines, recombinant protein vaccines to vaccines based on live-attenuated vectors and prime-boost strategies in different mouse models.
