“I'm not going to work today. I've been feeling sick for several days. Very tired and I had a fever last night. I was tested for COVID-19 and it was negative. I think I have the flu,” said Fabián R. from his bed at his house in Villa Crespo. What Fabian feels is similar to hundreds of Argentines affected by a new wave of influenza or influenza infections in the country that appears to be, arrived earlier this year.
While the Ómicron variant of the coronavirus is circulating in the country, another virus - which tends to impact in autumn and winter - is also affecting more people in the middle of summer. It is the flu virus - which is also known as the flu virus -, as warned days ago by an alert from the Ministry of Health of the Nation.
Since 2020, after the start of the coronavirus pandemic, there have been fewer cases of seasonal flu than in previous years. “a href="https://www.infobae.com/salud/ciencia/2022/02/19/superbacterias-la-pandemia-acelero-10-anos-el-problema-de-la-resistencia-a-los-antibioticos-en-argentina/" rel="noopener noreferrer" Since the beginning of the COVID-19 pandemic in Argentina, influenza virus activity has remained low,” the official alert said. However, since the first week of last December until now, an increase in the number of influenza cases, especially Influenza A H3N2, has been detected. Seasonal flu cases generally increase between April and October of each year in Argentina. Not in January, February or March.
“There was a resounding change of scenery between last summer and the current summer,” Teresa Varela, director of Epidemiological Surveillance and Outbreak Control at the Ministry of Health of the province of Buenos Aires, told Infobae, where 36 cases of influenza have been recorded since the beginning of this year. “The flu season, which usually starts after March, has been brought forward,” the official said.
“We identified an unusual increase in H3N2 flu cases at this time of year. This is also something that has already happened in countries in the region such as Brazil. We have the commitment of the Ministry of Health of the Nation that by the end of the month the vaccine will arrive and we will be able to start inoculating against the flu, starting with health personnel and groups at higher risk,” said Nicolás Kreplak, head of the Buenos Aires Ministry of Health.
CABA has also seen an increase in influenza cases in recent weeks and confirmed that, as the flu is occurring earlier than normal, influenza vaccination will begin next month. “The patent has changed and viral behavior has changed.
This year we detected in February and March a percentage of people with respiratory problems and high fever who are more linked to the flu virus, which is the flu virus,” said last Thursday at his regular press conference, the Minister of Health of the City of Buenos Aires, Fernan. Quiros.
“We imagine that throughout this year everything will return to its usual rhythm to what we were used to, but in fact we detected a certain number of important cases for the time of year of the year of the flu,” he added.
If we consider the cases of influenza that were detected during this summer according to the ages of those affected, the largest number of cases were detected in children under 5 years old in the first place and in young people between 25 and 34 years old in second place. The flu did not have the same impact throughout the country. The jurisdictions in which the highest number of positive samples were recorded are the province of Buenos Aires, Salta, Santa Fe, Tucumán and the city of Buenos Aires.
In most cases, influenza, which is a highly contagious respiratory viral disease, produces mild symptoms with symptoms such as fever, cough, nasal congestion, sore throat, headaches and muscles. But in some people there may be complications with shortness of breath and pneumonia, which require hospitalization. In the second week of February, there were 2 deaths in Argentina from influenza.
Why did flu cases increase in the middle of summer?
According to Infobae, infectious disease specialist Pablo Bonvehí, head of infectious diseases at CEMIC, “the increase in cases of influenza is probably explained by multiple factors. In other South American countries, such as Chile, Peru, Colombia and Brazil, cases mainly with the Influenza A H3N2 ″ subtype also increased.
The expert, a member of the Vaccine Committee of the Argentine Society of Infectology and the Scientific Committee of the Vaccinated Foundation, added: “It is not normal that we now have this circulation of the flu virus. It was also not normal for the virus to not circulate in 2020 and 2021 when coronavirus circulation predominated. Now the Influenza A H3N2 subtype has begun to circulate, predominant in the Northern Hemisphere. Surely this change is related to the fact that there are no more restrictions for traveling abroad. Having not been in contact with the flu virus for the past two years, people are more susceptible to acquiring the infection. There are also more cases of bronchiolitis and those affected by other respiratory viruses”.
Meanwhile, Leda Guzzi, from the Communication Commission of the Argentine Society of Infectious Diseases, explained to Infobae that “during the first two years of the pandemic, large-scale COVID-19 prevention measures, such as wearing a mask, confinement, distancing, ventilation, among others, helped reduce the transmission of influenza viruses and other respiratory viruses” around the world. “But since the end of last year, after the advancement of vaccination against COVID-19, there has been more intense citizen mobility and there has been a return of circulation of the influenza virus,” concluded the infectologist at the Olivos Clinic and the Santa Rosa Hospital of the Vicente López party
The health authority's warning is related to more cases of Influenza A H3N2 in the Northern Hemisphere and a globalization through travel that could have led to the extemporaneous emergence of the influenza virus in South America, according to doctor Guzzi. “The important thing is epidemiological and genomic surveillance and that people indicated for influenza vaccination receive the appropriate dose, such as children under 2 years of age, people over 65, and others who have risk factors,” he said.
COVID-19 Differences
Fever, dry cough, sore throat or chest, difficulty breathing These are some of the symptoms that may be responsible for suffering from COVID-19. But they are not the only ones, nor are these symptoms unique to this disease. The most common symptoms of COVID-19 are fever, cough, and tiredness. But there are many other possible signs and symptoms.
Both COVID-19 and the common cold are caused by viruses. COVID-19 is caused by SARS-CoV-2, while the common cold is most often caused by rhinoviruses. These viruses spread similarly and cause many of the same signs and symptoms. However, there are some differences.
Although symptoms of COVID-19 usually appear two to 14 days after exposure to SARS-CoV-2, symptoms of a common cold usually appear one to three days after exposure to a virus that causes the cold, according to experts at the Mayo Clinic.
Unlike COVID-19, a cold is often harmless. Most people recover from a common cold within three to ten days, although some colds can last up to two or three weeks.
On the other hand, to differentiate COVID-19 from allergy, on the other hand, it is important to understand that among the most common symptoms of this type of condition, which does not spread from person to person, are itching, runny nose, sneezing, coughing, eye irritation.
The main difference between allergies and viruses is fever. In this sense, a body temperature above 38 ºC could indicate the presence of a virus. Similarly, common allergies are unlikely to cause sudden loss of smell and taste, a characteristic symptom of COVID-19.
In addition, although COVID-19 can cause shortness of breath or difficulty breathing, seasonal allergies generally don't cause these symptoms unless you have a respiratory condition, such as asthma.
