According to Juarez Cunha, pediatrician and president of the SBIm (Brazilian Immunization Society), the main diseases that manifest in this period are respiratory, especially infectious, which are caused by viruses and bacteria, such as colds, flu, pneumonia and sinusitis.
Difference between flu and cold
As much as the symptoms are very similar, the flu and cold are different. First, the causative agents of both are different. According to Maria Lavinea Novis of Figueiredo, a doctor of infectious diseases, the flu is caused by influenza A and B viruses. The cold is caused by more than 100 types of viruses, the main ones belonging to the rhinovirus family.
In addition to the causative agent, there are other differences between the flu and the common cold. “In the common cold, the symptoms are relatively mild, such as a sore throat mild, sneezing, stuffy nose, low fever and a little discomfort, ”describes Dr. Silvana Fahel, pediatrician, haematologist and haemotherapist. The cold usually persists for 3 to 4 days and improves spontaneously. In this case, the person is usually able to carry out their usual activities, despite the discomfort.
“The flu is different, there is a high fever, a general condition maintained, a compromise, body aches, discomfort and a headache,” says the pediatrician. Performing physical and intellectual activities is compromised and the cycle of the disease is longer. The flu can be much more severe than a cold.
