New Infectious Threats: What You Need to Know and How to Safeguard Yourself

The spread of infectious diseases has become more frequent due to factors such as increasing global travel, closer human-animal interactions, and evolving climate conditions. These elements have intensified the risk of new diseases.

Recently at IDWeek, a key conference for experts in infectious diseases, specialists discussed which emerging diseases are most concerning and strategies to prevent them.

A Decade Post-Ebola: Are We Ready?

It has been a decade since the deadly Ebola outbreak of 2014, and experts like Dr. Krutika Kuppalli express concerns that we may currently be less equipped to deal with new infectious disease threats than before. Despite advances in medical diagnostics and vaccines, these outbreaks continue to pose severe global health challenges.

Dr. Kuppalli, present at the IDWeek conference, underscored that ongoing innovations are crucial but insufficient amid factors such as antibiotic resistance, increased travel, and climate change, which facilitate the spread of harder-to-treat infections.

Rising Infectious Diseases

Understanding newly emerging infections and taking action is vital. Experts, including those from Business Insider, shared what diseases are now on the rise, the risks they pose, and potential measures for prevention and treatment.

Antibiotic-Resistant E. coli

This strain of E. coli, although present in the human gut, is resistant to commonly used antibiotics. Dr. Yohei Doi explained that this bacterium is transmitted through skin contact, wounds, and contaminated excrement. In some rare cases, it can spread between animals and humans without usual infection signs.

The risk is particularly pronounced in healthcare settings, affecting people with compromised health, including young children, older adults, and frequent travelers. The challenge lies in the bacterium producing an enzyme that neutralizes carbapenem antibiotics, making treatment less effective.

Nontuberculous Mycobacteria (NTM)

These microbes, often found in the environment like water and soil, can lead to lung infections. Individuals who are susceptible include those with existing lung issues or weakened immune systems. Symptoms might include fatigue, weight change, and chronic coughing.

NTMs present a diagnostic difficulty due to their slow growth rate, complicating studies and treatments. Concerns are amplified because NTMs have developed significant antibiotic resistance.

Mycoplasma Genitalium (Mgen)

Rising cases of this sexually transmitted infection have prompted health warnings. Passed primarily through unprotected sex, Mgen can lead to reproductive health issues like pelvic inflammatory disease in women and remains a treatment challenge due to increasing antibiotic resistance.

Dengue Fever

Spread by mosquitos, dengue fever presents symptoms such as severe aches, rashes, and nausea. Most cases are reported in tropical regions, but climate shifts have allowed its spread to new areas, including parts of the United States.

The infection has no specific cure, but prevention focuses on avoiding mosquito bites, though vaccines are available for certain populations in high-risk zones.

Candida Auris

This yeast, recently recognized as a concern, easily spreads in hospital settings through surfaces and medical devices like catheters. It poses significant risk, particularly to those with compromised immunity, and is resistant to common antifungal treatments, elevating the risk of severe outcomes when contracted.

Aspergillus

Originating from mold, Aspergillus spreads via airborne spores, leading to respiratory issues. While many inhale spores without issues, those with immune vulnerabilities can suffer severely.

This fungus's rising resistance to treatment is concerning, largely attributed to the use of agricultural fungicides.

Advances in Managing Emerging Diseases

To improve the management of these infections, collaboration between patients and healthcare providers in using antibiotics judiciously is essential. Dr. Doi emphasizes the importance of wise drug use to ensure effectiveness.

Recognizing the need for systemic changes, consistent funding is crucial for prevention—like improved global surveillance and enhanced access to medical interventions, which could help curb the spread of infections.

In any case of suspected infectious disease symptoms, immediate contact with health services such as the CDC is encouraged for timely intervention.
