Question
Introduction
Some of the most common infections in the United States are hiding in many people’s blood. There are some very common diseases that often don’t cause any symptoms, sometimes for years, but can still be transmitted between people. Healthcare workers are at higher risk for these diseases because they come into contact with blood much more often than other professionals. But information is power, and knowing what these infections are is a first step to knowing how to protect yourself on the job and in the community.
Transmitted Through the Blood
Some pathogens that cause disease can float through the air, while others sit on surfaces waiting to find entry to a susceptible host. Microorganisms that are usually transmitted through blood and can cause disease in humans are called bloodborne pathogens. Because healthcare workers are more likely than others to come into contact with bloodborne pathogens, they need to know more about these contagious diseases to protect themselves and others from their spread. With robust safety measures in place, the risks can be mitigated effectively.
What are some of the emerging diseases and disorders? Identify and briefly describe some of these diseases and disorders and explain how or why they are emerging.

Emerging diseases and disorders often arise due to various factors such as environmental changes, globalization, increased human-animal interactions, and the evolution of pathogens. Below are some examples of emerging diseases and disorders, along with descriptions and explanations of their emergence:
### 1. **HIV/AIDS**
- **Description**: Human Immunodeficiency Virus (HIV) attacks the immune system and can lead to Acquired Immunodeficiency Syndrome (AIDS). It is primarily transmitted through blood, sexual contact, and from mother to child during childbirth or breastfeeding.
- **Emergence**: Initially identified in the early 1980s, HIV/AIDS emerged in part due to increased global travel and urbanization. The virus is believed to have originated from simian immunodeficiency virus (SIV) in non-human primates, and its spread was facilitated by social behaviors and lack of awareness.
### 2. **Hepatitis B and C**
- **Description**: Hepatitis B and C are viral infections that affect the liver. Hepatitis B is transmitted through exposure to infectious body fluids, while Hepatitis C primarily spreads through blood-to-blood contact.
- **Emergence**: Hepatitis B has been known for decades, but Hepatitis C only gained recognition in the 1980s. Their emergence is linked to practices such as unsafe medical procedures, sharing needles among drug users, and sexual transmission, often exacerbated by lack of vaccination and awareness.
### 3. **Zika Virus**
- **Description**: Zika is a viral infection usually transmitted by Aedes mosquitoes. While many cases are mild, it can cause severe birth defects when pregnant women are infected.
- **Emergence**: Zika re-emerged in the public health landscape in 2015 due to an outbreak in Brazil, influenced by climate changes and increased global travel that allowed mosquitoes to spread the virus to new areas.
### 4. **Ebola Virus Disease**
- **Description**: Ebola is a severe viral hemorrhagic fever with a high mortality rate, transmitted through direct contact with blood or bodily fluids of infected individuals.
- **Emergence**: Ebola outbreaks, primarily in Africa since it was first identified in 1976, have been linked to zoonotic transmission from wildlife. Factors such as deforestation, contact with infected animals, and inadequate healthcare infrastructure contribute to its reemergence.
### 5. **West Nile Virus**
- **Description**: West Nile Virus is primarily transmitted by mosquitoes and can cause neurological disease in some individuals.
- **Emergence**: First identified in the U.S. in 1999, the virus's emergence is attributed to changing climate patterns that affect mosquito populations and migrations, as well as global travel that facilitates its spread.
### 6. **Antimicrobial Resistance (AMR)**
- **Description**: AMR occurs when bacteria, viruses, fungi, and parasites evolve to resist the effects of medications that once treated them, leading to infections that are harder to treat.
- **Emergence**: The emergence of AMR is largely due to the overuse and misuse of antibiotics, both in human medicine and agriculture, as well as insufficient infection control measures and lack of new drug development.
### 7. **Nipah Virus**
- **Description**: Nipah virus causes severe respiratory illness and encephalitis. It is primarily transmitted through contact with infected bats or pigs, as well as from person to person.
- **Emergence**: First reported in Malaysia in 1998, its emergence is linked to environmental changes that bring animals into closer contact with humans and the growing demand for fruit bats in certain regions.
### Conclusion
Emerging diseases and disorders pose significant challenges to public health, especially for healthcare workers who are at a higher risk of exposure. Understanding the factors driving the emergence and spread of these infections is crucial for developing effective prevention and control strategies. Regular training, vaccination, and implementation of safety protocols in healthcare settings are vital steps in protecting healthcare professionals and the communities they serve.
