            Abstract

            Infectious diseases are a major threat to global health and the economic stability of societies worldwide. To prevent outbreaks, monitoring the growth trends of infectious diseases appears to be particularly important and necessary. Herein, data from epidemiological websites, such as the World Health Organization and National Health Council are used to illustrate the outbreak trends for infectious diseases worldwide. In the context of the COVID-19 pandemic, a global resurgence in other infectious diseases has been observed, particularly influenza in the United States. Proper surveillance and effective strategies are urgently required to keep emerging infectious diseases under control.

            INTRODUCTION

            Infectious diseases, with their unpredictable and far-reaching consequences, have been an important part of human history. To control the spread of infectious diseases worldwide, and protect people’s lives and safety, regular analysis of global infectious disease cases is critical. In the past month, cases of COVID-19 and monkeypox (Mpox) have significantly decreased. On January 30, 2023, the World Health Organization (WHO) declared that the COVID-19 pandemic continues to constitute a public health emergency of international concern, regarding the management of the COVID-19 pandemic transition period and mitigating potential negative effects. Meanwhile, the United States is having its worst influenza season since the COVID-19 pandemic. Dengue, measles and cholera remain public health concerns worldwide. Simultaneously, more attention should also be paid to certain sporadic infectious diseases, such as Chikungunya fever, legionellosis, poliomyelitis, avian influenza and scarlet fever, to avoid global pandemics. The global prevalence of low-incidence infectious diseases from December 24, 2022 to January 23, 2023 was mapped by using the Global Outbreak Information Surveillance System (Fig 1).

            COVID-19

            COVID-19 has rapidly overwhelmed the world since its sudden outbreak in 2019. In the past month, global cases of SARS-CoV-2 infection reached more than 50 million according to the WHO. The Western Pacific region had the largest proportion, at 89.86%, as compared with only 0.04% in the Eastern Mediterranean region and 0.05% in the Southeast Asia region. Although the epidemic was severe in the Western Pacific region, daily new cases of COVID-19 decreased continually from a peak above 5 million to a trough of approximately 100,000, thus indicating that effective strategies might have been able to prevent further local spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Fig 2A, B).

            FIGURE 2 |

            Statistics on new confirmed cases and deaths due to COVID-19 worldwide daily. A, C: New cases and deaths due to COVID-19 have been reported daily on every continent (The primary coordinate on the left is the columnar ordinate, the secondary coordinate on the right is the broken line ordinate). B, D: Continent-specific proportions of new confirmed cases and deaths due to COVID-19 (December 24, 2022 to January 23, 2023; data were obtained from the World Health Organization website: https://COVID19.who.int/).

            Owing to continuing mutation of SARS-CoV-2, the ongoing pandemic has resulted in severe morbidity and mortality in the past 3 years. The global deaths due to COVID-19 reached approximately 134,000 over the past month, among which the Western Pacific region accounted for the highest proportion (67.08%), followed by the Americas (16.52%), Europe (15.66%), Southeast Asia (0.5%), the Eastern Mediterranean (0.16%) and Africa (0.08%). The daily deaths in the Western Pacific region remained above 1,000, peaking at approximately 4,500 in the middle of the past month, then decreasing to approximately 1,500 (Fig 2C, D).

            MPOX

            Mpox, an emerging zoonotic disease, has become a global concern, owing to the increasing number of human outbreaks in recent months [1]. Approximately 1,400 Mpox cases were reported by the WHO in the past month, occurring primarily in the Americas (Fig 3A). The daily reported Mpox cases in different regions are described in detail in Fig 3B-D. Compared with the previous epidemic data released by the WHO, the global Mpox infections substantially decreased over the past month. However, strategies such as vaccination with smallpox vaccine remain necessary to control the re-emergence of the Mpox virus.

B: Mpox cases confirmed in the regions of the Americas. C: Mpox cases confirmed in the European region. D: Mpox cases confirmed in the Western Pacific region. Data were obtained from the World Health Organization website (https://worldhealthorg.shinyapps.io/mpx_global/#3_Detailed_case_data).

            CHOLERA

            Cholera, caused by Vibrio cholerae, is an infectious disease occurring mainly in developing countries with deficiencies in water quality [2]. The disease remains endemic in approximately 17 countries, primarily Afghanistan and Syria, according to the data shown in Table 1. In 2022, the cumulative reported cholera cases exceeded 240,000 in Afghanistan (Table 1). Thus, oral cholera vaccines should be recommended for use in resource-limited settings to control and prevent outbreaks. Furthermore, improving environmental health conditions, such as water and sanitation, remains an effective approach to limiting the spread of cholera.

            DENGUE

            Dengue, the most common mosquito-borne disease, is caused by four antigenically related but distinct serotypes dengue virus (DENV-1 to DENV-4) transmitted by Aedes spp. mosquitos [3]. The data in Table 2 show that the greatest burden of the disease was reported in tropical and subtropical regions, such as Brazil, where the cumulative dengue cases in the entire year of 2022 exceeded 2 million. Meanwhile, more than 200,000 dengue cases were found in Vietnam, Zimbabwe and the Philippines (Table 2). Without effective intervention measures, Dengue is predicted to increase in terms of both disease burden and geographic range in the future.

            MEASLES

            Measles is a vaccine-preventable, highly contagious disease caused by an RNA virus [4]. However, owing to the limited immunization campaigns and political conflicts in many countries, a global resurgence in measles has been observed since 2016. In the past month, many countries have faced measles outbreaks, particularly Afghanistan (Table 3). The eradication of measles is feasible, but effective vaccination, access to the healthcare systems and public engagement are urgently needed.

            INFLUENZA

            Seasonal influenza is an acute respiratory infection caused by the influenza A and B viruses [5]. It is generally prevalent from January to March and July to August. According to the U.S. CDC, the 2022–2023 influenza season, in which 16,000–48,000 people have died from influenza, is the worst influenza season since the start of the COVID-19 pandemic. Although influenza activity is currently declining with respect to that in December (Table 4), a second influenza peak may occur in the future, as has been observed in some influenza seasons, according to John Huddleston, a staff scientist at the Bedford Laboratory at the Fred Hutchinson Cancer Center. The epidemic of influenza provides a reminder that COVID-19 is not the only viral disease that must be considered, and that influenza remains a major public health threat.

            CHIKUNGUNYA FEVER

            Chikungunya fever, a febrile disease, is caused by chikungunya virus, and is associated with long-term sequelae of arthralgia and myalgia [6]. It is distributed primarily in tropical and subtropical regions where the winter temperature is above 18°C. In the past month, some cases were reported in Malaysia, Peru, Guatemala, Paraguay and Brazil (Table 5). Among them, Paraguay has had a marked increase and high number of cases. The proximity of mosquito breeding sites to human habitation areas is a risk factor for Chikungunya fever; therefore, prevention and control measures should focus on limiting hospitable environments for mosquitoes and removing containers in which mosquitoes breed.

            LEGIONELLOSIS

            Legionellosis is a severe respiratory disease found in not only natural habitats, such as freshwater reservoirs, watercourses, moist soil and composted material, but also in man-made water systems, such as plumbing systems, air-conditioning units, bathtubs and showers [7]. Outbreaks of legionellosis have occasionally been reported worldwide (Table 6).

            CONCLUSION

            COVID-19 has posed an unprecedented global health crisis since its outbreak in 2019, and the introduction of several vaccines has brought hope to a virus-weary world. However, the continuing emergence of variants of SARS-CoV-2 has prompted a question of whether COVID-19 eradication remains possible, given the limited health care resources and fatigue of the epidemic. This question has no conclusive answer. However, multiple strategies including proper sanitation and hygiene, efficacious vaccines and antiviral drugs would accelerate the elimination process.

            In this influenza season, many individuals in America have been affected by influenza, and a second influenza peak is projected to emerge in the near future. The reasons for the rebound in influenza virus might be attributable to the relaxation of public health and social distancing strategies, and low population influenza immunity. Therefore, surveillance of influenza activity is important in the post-COVID-19 era. In contrast, the number of global Mpox infection cases significantly decreased in the past month, although surveillance systems and routine immunization programs still must be improved to control further spread of Mpox virus.

            Mosquito-borne diseases, including dengue, Chikungunya fever and Zika, remain prevalent in tropical and subtropical regions, such as Brazil. Emergence and re-emergence of arboviruses is influenced by climate change factors, including rising temperatures, precipitation and human activity. Human activities involving travel, urbanization, deforestation and reforestation affect virus-mosquito-primate host interactions, and consequently viral transmission in both domestic and wild environments. Thus, efficient prevention of arboviral disease outbreaks must include mosquito control strategies that interrupt human-vector contact.

            Overall, the outbreaks of multiple infectious diseases occurred primarily in the regions of Africa, South America and Southeast Asia, given their geographical locations and climatic conditions. The public health infrastructure and response efficiency of individual countries may determine outbreak severity. Therefore, governments and public health authorities must adopt comprehensive and effective strategies tailored to local epidemics, to mitigate or even eliminate the threats caused by infectious diseases.
