With the arrival of the fall that began on April 20, humidity will drop, increasing respiratory illness. Now that the use of masks against Covid-19 has ended, the number of cases should increase further.

The World Health Organization (WHO) estimates that the flu causes serious harm to 3.5 million people each year. Children, the elderly, lung diseases, heart and resistance problems suffer the most.
With the arrival of autumn – which began on April 20 – the decrease in relative humidity typical of this season, which is associated with an increase in air pollution, will significantly increase respiratory diseases. Most of them are contagious, caused by viruses and secondly by bacteria. Continuous and sudden weather fluctuations, as well as the removal of jackets and blankets from the closet after long storage, also increase the incidence of respiratory problems. In addition to the flu, colds, and pneumonia, allergic rhinitis and sinusitis are common diseases at this time of year.
The decline in the mandatory use of masks by Vita Hospital’s infectologist, Dr. Marta Fragoso, in many Brazilian cities also promises to increase the number of cases of various diseases in the coming months. Most Brazilian states have already abolished mandatory use in open and enclosed spaces. “Removing masks tends to increase human exposure to infectious particles and air with high levels of pollutants. The mask used during the most critical moments of the Covid-19 pandemic was a good practice for preventing infectious respiratory diseases in general and should be maintained in some special situations, ”he argues.
Respiratory diseases of the respiratory tract can be classified as “airborne” (transmitted through aerosols in the air) and “infectious” that spread along other routes, including larger droplets. Aerosols are small liquid particles in the airways that are produced, for example, when you exhale, talk or cough. These particles are suspended in the air for some time and may contain live viruses. Medical recommendations indicate that when a person has symptoms suggestive of respiratory distress, it is essential that the person isolate themselves and seek an accurate diagnosis to guide treatment.
Fiocruz’s latest InfoGripe newsletter reports an increase in respiratory syndromes in children. According to the report, preliminary laboratory data suggest that respiratory Syncytial Virus (RSV) cases are increasing in the zero- to four-year-old age group and that the decline in Covid-19 cases is halting in five-year-olds. For the 11-year-old age group. An infectologist, especially when we live, we need to double our attention. “The increase in respiratory syndromes in both children and adults and the elderly is due to new viral and even bacterial pathogens that are diverse in their mutations and resistance to environmental contamination,” he explains.
Marta also emphasizes that the best methods of prevention are adequate hydration, hand hygiene with gel alcohol, avoiding agglomerations, ventilating the environment, keeping the label coughing and sneezing, keeping vaccines up to date, and using room humidifiers. , ensuring the cleanliness of the environment. , free of dust and mites, and consider a medical evaluation to get the right diagnosis and treatment.
