Respiratory Illnesses Surge as Winter Begins: Flu, COVID-19, and RSV Cases Rise
the onset of winter has brought with it an anticipated increase in respiratory diseases, with influenza currently leading the surge, followed by COVID-19 and Respiratory Syncytial Virus (RSV).
as temperatures drop, the risk of contracting these viruses rises significantly.According too a leading academic and researcher at the Faculty of Medicine and coordinator of the University Research Program on Epidemiological and Emerging Risks (PUIREE) from UNAM, influenza is currently the most prevalent, but all three viruses pose a threat, particularly to vulnerable populations.
How Respiratory Viruses Spread
Both influenza and COVID-19 are transmitted through respiratory droplets expelled during common actions like sneezing, coughing, or even talking.Infection can also occur by touching contaminated surfaces and then touching one’s face. “In addition to these,” the researcher explained, “other viruses, such as enterovirus and rhinovirus, are circulating and can cause similar symptoms – a runny nose, sneezing, body aches, headache, and sometimes, a sore throat and fever.”
Understanding Initial Symptoms
Early influenza symptoms often present with more pronounced effects, including generalized muscle pain, fever, headache, throat pain, and cough. These initial symptoms can be particularly intense,setting influenza apart from some other respiratory illnesses.
Influenza Expected to Dominate This Winter
The researcher anticipates a particularly strong influenza season, mirroring trends already observed in the United States, were infection rates are the highest they’ve been in over a decade. In contrast, COVID-19 cases are currently lower compared to previous years at this time, though this could change in the coming weeks.
“We would expect that, in Mexico, influenza will continue to predominate and that the Covid-19 occurs with a frequency that is not very important,” the researcher stated.
RSV Cases Also on the Rise
Alongside influenza and COVID-19, RSV infections are also being reported in high numbers.This virus specifically causes nasal and eye discomfort, throat irritation, and a persistent cough due to inflammation of the respiratory epithelium.
Vulnerable Populations at Increased Risk
While infection rates are high across all age groups, children under five and adults over 65 are particularly susceptible to more severe symptoms. This underscores the critical importance of vaccination to protect these vulnerable populations.
Preventative Measures Remain Key
Beyond vaccination, preventative measures remain crucial. These include frequent handwashing, wearing face masks on public transportation, ensuring adequate ventilation in enclosed spaces like classrooms and offices, covering the mouth with a forearm when sneezing, and using disposable tissues when coughing. Avoiding crowds, when possible, is also recommended.
Vaccination Timing and Recommendations
The flu season is expected to continue through April or May, making this an ideal time for those who haven’t yet been vaccinated against influenza and COVID-19 to do so. Additionally, individuals aged 60 and over are advised to receive a vaccination against Strep
