Future Trends in Infectious Disease Outbreaks and Technological Advancements
The Evolution of Disease Outbreaks
Throughout human history, disease outbreaks have emerged and re-emerged. With the advent of global travel, outbreaks can now move quickly among and between populations. The COVID-19 pandemic is a stark reminder of how quickly a disease can disrupt the world. During this period, significant technological advancements were achieved, such as the rapid development and rollout of vaccines and the global tracking of variants. These advancements underscore the need for continuous innovation to fight emerging infectious diseases and new strains of existing microbes.
Post-COVID-19 Infectious Disease Outbreaks
Mpox: A Resurgence of a Known Virus
In 2022, shortly after the height of the COVID-19 pandemic, the world faced another threat: mpox, formerly known as monkeypox. Unlike SARS-CoV-2, mpox is not a novel virus; it was first identified in laboratory monkeys in 1958 and had been reported in human cases since 1970. The 2022 global outbreak of mpox, driven primarily by sexual transmission or body contact, resulted in about 250 deaths with a fatality rate of 0.2%. An ongoing outbreak in Central Africa, starting in 2023, has claimed about 900 lives with a higher fatality rate of 5%. Currently, there is no FDA-approved treatment for mpox.

Avian Influenza: An Unusual Host
In early 2024, the United States saw an avian influenza outbreak among dairy cows, a first in history. The infection, typically found in birds, has spread to about 973 cattle in 17 states and resulted in about 70 human cases among those associated with farm animals. This outbreak highlights the potential for zoonotic diseases to jump species and emphasizes the need for vigilant surveillance.
This outbreak however is less concerning than future outbreaks, as shown in this short video on future emerging diseases:
hMPV: A Respiratory Threat in Northern China
Recently, a respiratory outbreak known as hMPV has overwhelmed hospitals in Northern China. Affecting children, adolescents, and senior citizens, the origin of this outbreak remains unknown. This underlines the continuous threat posed by emerging infectious diseases and the need for rapid and efficient outbreak management.
The Rise of Untreatable Sexual Transmitted Diseases
Gonorrhoea: The Threat of Antibiotic-Resistant Strains
Gonorrhoea, a widely known sexually transmitted infection (STI), infected approximately 80 million people in 2020. While most cases are treatable, the rise of antibiotic-resistant strains poses a significant health threat. Resistant strains can lead to infertility and even cancer, underscoring the urgency for innovative treatment solutions.
Mycoplasma genitalium: An Emerging STI Threat
Mycoplasma genitalium, the causative agent for non-gonococcal urethritis, is an understudied and challenging bacterium. Naturally resistant to many antibiotics, it can lead to infertility, increased susceptibility to HIV, and other serious health complications. The World Health Organization (WHO) and researchers like Idowu Olawoye are using genomic surveillance to control and study these infections, highlighting the importance of advanced diagnostic tools and effective surveillance methods.
The Role of Genomic Surveillance
Genomic surveillance, which uses next-generation sequencing technology, has become a crucial tool in identifying and tracking pathogens. This technique was pivotal during the COVID-19 pandemic, aiding in the rapid identification of new variants.
Genomic Surveillance: A Game Changer
Genomic surveillance can help us understand and tackle emerging threats more effectively. It allows for the development of rapid diagnostic tools and the identification of drug-resistant strains, particularly for challenging bacteria like Mycoplasma genitalium. The implementation of affordable, user-friendly diagnostic tools and effective vaccines in endemic regions, exemplified by the COVID-19 self-test kit, is a key focus of ongoing research.
Proactive Measures for Future Outbreaks
Pathogens are constantly evolving, making continuous innovation essential. Utilizing genomic surveillance, rapid and sensitive diagnostic tools, and innovative methods for halting the spread of untreatable infections ensures we stay ahead of the curve. Investing in research and development remains crucial in our perpetual battle against infectious diseases.
FAQ: Understanding Emerging Infectious Diseases
Q. What is genomic surveillance, and how does it help in tracking infectious diseases?
A. Genomic surveillance uses next-generation sequencing technology to identify specific strains of pathogens and track their genetic characteristics. This helps in understanding the virulence of strains and developing effective diagnostic tools and vaccines.
Q. How does antibiotic resistance affect the treatment of infectious diseases?
A. Antibiotic resistance can make infections difficult to treat, leading to prolonged illness, increased healthcare costs, and, in some cases, fatalities. It underscores the need for continuous research and new antibiotic development.
Q. What measures can be taken to prevent the spread of infectious diseases?
A. Measures include effective genomic surveillance, rapid diagnostic tools, public health education, strict hygiene practices, and global collaboration in disease management and research.
Do you know? Technology has helped us monitor emerging diseases better during the last years. For example, a global database of coronavirus genomes currently holds a record of over six million sequences, representing almost 9 million unique mutations. Research on mitochondrial DNA offers a powerful new toolkit undergirding personalized medicine and enabling us to understand an individual’s vulnerability to various autoimmune and inflammatory diseases
