The Ebola virus is transmitted through contact with bodily fluids of infected animals or humans and can cause severe symptoms, including hemorrhagic fever, vomiting, diarrhea, and organ failure, leading to death in up to 90% of cases. Outbreaks have been reported in several countries in Africa and have been associated with high levels of morbidity and mortality. The World Health Organization and other health organizations continue to work together to monitor and respond to outbreaks, including providing support for case management, infection prevention and control, and community engagement. Vaccines have been developed and are being used in outbreak response efforts, but challenges remain in ensuring access to these vaccines and implementing effective control measures in affected areas.
2. Influenza pandemic risks increase
The risk of an influenza pandemic has been a recurrent threat and remains one of the top communicable disease threats in 2023. The emergence of new strains of influenza viruses and their ability to spread rapidly across borders pose a significant risk to global health security. The COVID-19 pandemic has highlighted the importance of pandemic preparedness and response, and it is crucial to remain vigilant to the possibility of a future influenza pandemic. The World Health Organization (WHO) has identified the need for continued surveillance and research to monitor the evolution of influenza viruses and develop effective countermeasures, such as vaccines and antiviral medications, to mitigate the impact of a potential pandemic. It is essential to prioritize investments in public health systems, strengthen international cooperation, and empower communities to effectively respond to the threat of an influenza pandemic.
3. Antimicrobial resistance on the rise
Antimicrobial resistance (AMR) continues to be a significant public health threat, and its impact is expected to increase in 2023. The overuse and misuse of antibiotics have led to the emergence of AMR, which is a phenomenon whereby bacteria evolve to become resistant to antibiotics. This poses a serious challenge to the treatment of infectious diseases, making it difficult to control outbreaks and increase morbidity and mortality rates. The problem is further exacerbated by the lack of new antibiotics in development, leading to a potential shortage of effective treatments. Addressing the issue of AMR requires a concerted effort from healthcare providers, policymakers, and the public to promote responsible use of antibiotics and invest in research to develop new treatments. Failure to act on this issue could have dire consequences for global health and the economy.
4. Measles outbreaks in low-income countries
Measles outbreaks continue to pose a significant threat in low-income countries, making it an important communicable disease threat in 2023. These outbreaks have been fueled by various factors, including inadequate vaccination coverage, poor healthcare infrastructure, and limited access to healthcare services. In particular, the COVID-19 pandemic has had a significant impact on routine immunization programs, exacerbating the problem of measles outbreaks in low-income countries. This has resulted in a devastating toll on affected populations, leading to deaths and long-term health complications. To address this issue, it is essential to enhance efforts to provide access to vaccines, strengthen healthcare systems, and improve disease surveillance and response mechanisms in affected areas.
5. Yellow fever resurgence in Africa
Yellow fever, a viral hemorrhagic fever transmitted by infected mosquitoes, is making a concerning resurgence in Africa. In recent years, outbreaks have occurred in multiple countries including Angola, Democratic Republic of Congo, and Nigeria. The World Health Organization (WHO) estimates that up to 60,000 people die from yellow fever annually, with the majority of cases occurring in Africa. This resurgence is particularly worrying as there is a global shortage of yellow fever vaccine, leaving many vulnerable populations at risk. The WHO is working closely with affected countries to prevent and control outbreaks through vaccination campaigns and mosquito control measures. However, continued vigilance and investment in prevention and control measures is necessary to combat the concerning resurgence of yellow fever in Africa.
6. MERS-CoV transmission in healthcare
According to the World Health Organization, Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a communicable disease that poses a significant threat to global public health. The transmission of the virus in healthcare settings has been identified as a top-ten communicable disease threat in 2023. MERS-CoV is primarily transmitted through contact with infected camels or consumption of raw or undercooked camel milk or meat. However, transmission can also occur in healthcare settings through close contact with infected patients, especially in the absence of appropriate infection prevention and control measures. The healthcare workers are at an increased risk of contracting MERS-CoV and spreading it to other patients and healthcare workers. It is crucial to implement effective infection prevention and control measures to prevent the transmission of MERS-CoV in healthcare settings. This includes early identification and isolation of suspected cases, appropriate use of personal protective equipment, and adherence to hand hygiene practices.
7. Poliovirus transmission in conflict zones
Poliovirus transmission in conflict zones remains a significant communicable disease threat in 2023. The ongoing conflicts in various regions have hindered the efforts to eradicate poliovirus. The difficulty of providing adequate healthcare services in these conflict zones has led to a decrease in the rate of vaccination coverage, increasing the chances of poliovirus transmission. Furthermore, the movement of people across borders within these conflict areas has made it more challenging to track and prevent the spread of the virus. The emergence of vaccine-derived poliovirus (VDPV) strains has also been reported in these areas, further adding to the complexity of polio eradication efforts. Therefore, it is crucial to address poliovirus transmission in conflict zones as a top priority in global health interventions to achieve the goal of a polio-free world.
8. Tuberculosis drug resistance surges
Tuberculosis (TB) remains one of the most pressing global health challenges, with drug-resistant strains posing a particularly serious threat. In recent years, there has been a surge in cases of TB drug resistance, with some strains now resistant to multiple first-line antibiotics. This development is a major concern as it can lead to longer and more expensive treatment regimens, as well as higher mortality rates. Addressing the issue of TB drug resistance requires a comprehensive approach that includes increasing access to diagnostic tests and new treatments, improving infection control measures, and addressing social and economic factors that contribute to the spread of the disease. Failure to address this growing threat could have far-reaching consequences, both in terms of individual health outcomes and global health security.
9. Cholera epidemic in vulnerable populations
According to the World Health Organization (WHO), cholera remains a major threat to public health, particularly in vulnerable populations, and is one of the top ten communicable disease threats in 2023. Cholera is a bacterial infection that affects the intestines and can cause severe dehydration and even death if left untreated. The disease is often spread through contaminated water and food, and is most common in areas with poor sanitation and hygiene practices. Vulnerable populations, such as those living in poverty, refugees, and displaced persons, are at a higher risk of contracting cholera due to their limited access to clean water and proper sanitation facilities. In order to prevent and control cholera outbreaks in vulnerable populations, it is crucial to prioritize investments in improving sanitation and hygiene infrastructure, as well as providing access to safe drinking water and effective treatment.
10. Dengue fever epidemic in Asia
