Supergripa en Antioquia: ¿Qué es, síntomas y por qué se propaga?
Recent rains in Antioquia, Colombia, have coincided with a rise in reported respiratory infections. While official case numbers are still being tallied, municipalities like Rionegro have already seen a 23% increase in these illnesses in 2025. One infection, gaining attention, has been dubbed “supergripa.”
What is “Supergripa”?
According to Juan Camilo Marín Roldán, a physician and professor at the Universidad CES, “supergripa” is simply a common cold or flu. Infections are caused by microorganisms – bacteria, viruses, fungi, and parasites – with viruses being the most prevalent. These include influenza A(H3N2), coronaviruses like the one responsible for the COVID-19 pandemic, and other viruses such as parainfluenza and rhinovirus.
Currently, a global surge in infections is being driven by the influenza A(H3N2) subtype. While cases in Latin America remain relatively scarce, the first case in Colombia was documented late last month, linked to international travel. Antioquia is on alert due to the increased spread during the winter season.
Why Does it Spread More During Rainy Seasons?
The increased transmission of respiratory infections during winter is not a myth. Lower humidity allows respiratory particles from coughs and sneezes to remain suspended in the air longer, traveling further on dry winds. Additionally, colder air dries out nasal and oral mucous membranes, reducing the effectiveness of the body’s natural defenses.
Furthermore, cold temperatures cause vasoconstriction, reducing blood flow to the respiratory tract and hindering the delivery of immune cells. Individuals with malnutrition, extreme ages, pregnancy, or compromised immune systems – such as those with HIV or cancer – are also more vulnerable.
Why the Term “Supergripa”?
The term “supergripa” does not indicate a more deadly or severe virus. It’s used because of the infection’s rapid rate of transmission. While the outbreak in Latin America is not as aggressive as those in North America, Europe, and Asia, cases are expected to rise over time. The name reflects ease of spread, not increased severity.
What are the Symptoms of “Supergripa”?
Symptoms are typical of a common cold or flu: nasal congestion, cough, sore throat, fever, general malaise, headache, and loss of appetite. These symptoms usually last around a week. The illness poses a greater risk to pregnant women and individuals with underlying health conditions.
Can Someone Die from “Supergripa”?
Yes, but not because the virus itself is exceptionally lethal. Death is more likely due to the compromised immune system of the infected individual.
How Can You Prevent Infection or Limit Spread?
If you experience respiratory symptoms, wear a mask, wash your hands frequently, and maintain a safe distance from others. Stay warm, and hydrate with fluids like honey, ginger, and vitamin C – all scientifically proven to be beneficial.
The illness typically resolves on its own within 7 to 10 days as the body’s immune system fights it off. However, seek immediate medical attention if you experience symptoms like difficulty breathing, chest pain, coughing up blood, or altered mental state.
Frequently Asked Questions
What preventative measures should international travelers take?
Travelers are advised to get vaccinated at least two weeks before their trip, wear masks in airports or crowded places if they have symptoms, and wash their hands frequently.
Does the current vaccine protect against influenza A(H3N2)?
Yes. The National Institute of Health has confirmed that the 2025 influenza vaccine includes the A(H3N2) strain, making it the most effective tool for preventing serious complications, hospitalizations, and deaths associated with this virus.
What measures should be taken to avoid spreading the virus once infected?
If you have respiratory symptoms, use a mask, wash your hands, and maintain a safe distance from others.
As cases continue to be monitored, will public health recommendations evolve to address the changing dynamics of this respiratory season?
