Many of us have been impacted by outbreaks of disease in our lifetimes. Throughout history, humans have battled outbreaks of disease; many have lost their lives to diseases before treatments and cures were discovered. Modern science and medicine have become efficient in developing vaccines and medications to control and treat outbreaks, but whether the diseases will ever truly be eradicated is in question. Considering how many of these infectious diseases exist and how easily they spread, it is important to remember safety issues to reduce and prevent transmission. For your initial post, reflect over the past decade and recall a news-breaking infectious outbreak of a disease that made an impact on you.

Please include a link to a news article or video related to your outbreak in your initial post. Include the following in your post: Disease name, infectious agent (is the disease bacterial, viral, or fungal? List the specific organism - genus and species), mode of transmission, signs and symptoms of the disease, treatment (or treatments) available. Try not to duplicate another classmate’s topic (make your subject line your disease so it is easy to check). Explain how that story changed the way you interacted with people, family, or friends.

Introduction

In recent years, infectious disease outbreaks have remained a significant public health concern worldwide. One particularly impactful outbreak in the last decade was the COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2. Its rapid spread and profound impact on daily life, economies, and healthcare systems worldwide made it a defining health crisis of the 21st century.

Disease Name and Infectious Agent

The disease is COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is a viral pathogen belonging to the Coronaviridae family, characterized by its enveloped, positive-sense single-stranded RNA genome. This virus is distinct from other coronaviruses that cause the common cold, representing a new strain that triggered a global pandemic.

Mode of Transmission

SARS-CoV-2 primarily spreads through respiratory droplets expelled when infected individuals cough, sneeze, talk, or breathe. The virus can also spread via contact with contaminated surfaces followed by touching the face, especially the mouth, nose, or eyes. Aerosolized particles can linger in enclosed spaces, making airborne transmission a concern, particularly in poorly ventilated settings.

Signs and Symptoms

COVID-19 presents with a broad spectrum of symptoms ranging from mild to severe. Common signs include fever, cough, shortness of breath, fatigue, muscle or body aches, loss of taste or smell, sore throat, and headaches. Severe cases may lead to pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, and death, especially among vulnerable populations such as the elderly and immunocompromised individuals.

Available Treatments and Vaccines

Initially, treatment options were limited to supportive care, including hydration, oxygen therapy, and managing symptoms. Over time, several vaccines were developed, such as mRNA vaccines (Pfizer-BioNTech and Moderna), vector-based vaccines (AstraZeneca, Johnson & Johnson), and protein subunit vaccines, significantly reducing severe disease and death. Antiviral medications like remdesivir and corticosteroids such as dexamethasone are also used to manage severe cases. Public health measures, including mask mandates, social distancing, and quarantine protocols, complemented vaccination efforts to control the spread.

Impact on Personal Behavior and Interactions

The COVID-19 pandemic dramatically changed my interactions with people, family, and friends. It heightened awareness of personal hygiene, leading to more frequent handwashing and use of hand sanitizers. Social distancing and remote work became the norm, reducing physical interactions. The importance of mental health was emphasized as social isolation increased. The experience fostered greater appreciation for health and community support, reinforcing the value of preventive measures in safeguarding ourselves and others from infectious diseases.

Conclusion

The outbreak of COVID-19 underscored the importance of preparedness, vaccination, and public health strategies in combating infectious diseases. It also highlighted how infectious diseases can alter lifestyles and societal functions. Ongoing research and global cooperation are essential for developing effective prevention and treatment methods to better handle future outbreaks.
