COVID-19. Early diagnosis is key to managing the surge.">
Pharmacies in Belo Horizonte, Brazil, are experiencing a important surge in demand for respiratory virus testing, particularly for influenza A and COVID-19, as winter commences [[1]]. Drugstore Araujo reported a 260% increase in test requests in May compared to April. In the first half of June, the number of tests performed already matched the projected monthly average, with nearly 40% yielding positive results for influenza A.
Rising Cases of severe Acute Respiratory Syndrome
The Infogipe Bulletin, released by the Oswaldo Cruz Foundation (Fiocruz) on June 18th, indicates a growing number of severe acute respiratory syndrome (SRAG) cases across parts of Brazil. This bulletin, referencing data from June 8th to 14th, highlights the increasing pressure on healthcare systems [[2]].
Did You Know? The centers for Disease Control and Prevention (CDC) tracks multiple respiratory viruses, including influenza, RSV, and SARS-CoV-2, to monitor trends and provide public health guidance.
The Importance of Early Diagnosis
An infectologist in Minas gerais emphasizes the importance of early diagnosis of respiratory diseases to initiate timely treatment and prevent complications, especially for vulnerable populations like the elderly and children. Early intervention can considerably reduce hospitalizations and improve patient outcomes [[3]].
With the onset of winter on June 20th, cases of respiratory illnesses typically rise, making early diagnosis crucial to prevent severe illness and overburdening healthcare services. quick tests available at pharmacies offer a convenient option for detecting infections and seeking prompt medical attention upon the appearance of initial symptoms.
Rapid Tests vs. PCR Tests
Melissa Valentini, an infectologist from Hermes Pardini Laboratory, explains that rapid tests available in pharmacies detect antigens and have lower sensitivity compared to laboratory-based PCR tests. Antigen tests identify parts of the virus,while PCR tests analyze the virus’s genetic material.Valentini advises that testing should occur as soon as symptoms appear, primarily to differentiate between COVID-19 and influenza. Medications are available for treating both conditions in high-risk individuals within the first three days of symptom onset.
Pro Tip: If you experience respiratory symptoms, contact your healthcare provider to determine the most appropriate testing and treatment options for your specific situation.
Identifying Various Respiratory Viruses
Laboratory tests can identify a range of respiratory viruses beyond influenza and COVID-19, including Respiratory Syncytial Virus (RSV), which can cause severe respiratory illness in young children and older adults. Consulting a doctor is recommended to determine the most suitable test based on the patient’s condition, potentially through an online consultation.
Infectologists also remind the public that individuals with respiratory illnesses can transmit the virus for five to ten days. Therefore, wearing masks, practicing hand hygiene, and adhering to cough etiquette are essential to prevent transmission.
Public Health Initiatives
belo Horizonte City Hall (PBH) follows Ministry of Health protocols by testing patients with flu-like symptoms, such as fever, sore throat, cough, and body pain, who seek care at Emergency Care Units (UPAs). Testing is conducted through sampling and in sentinel hospitals to monitor virus circulation. COVID-19 tests are available at health centers for individuals with respiratory symptoms belonging to priority groups, with other users able to schedule tests through the PBH portal.
The Minas Gerais State Department of Health (SES-MG) also adheres to Ministry of health guidelines, screening patients based on symptom severity, oxygen saturation, respiratory effort, and persistent fever. Epidemiological criteria, such as comorbidities, age, vaccination status, and recent virus exposure, are also considered.Laboratory testing is mandatory for hospitalized SRAG cases, respiratory-related deaths, and cases included in sentinel surveillance.
InfoGripe Findings
According to Fiocruz’s InfoGripe survey, 14 of the 27 state capitals in Brazil are experiencing alert, risk, or high-risk levels of SRAG activity, with a long-term upward trend. Belo Horizonte is among these cities. Influenza remains the primary cause of hospitalization for young people, adults, and the elderly, with higher incidence and mortality rates among the elderly. While SRAG cases have begun to decline in some states in the Midwest and Southeast, including Tocantins, hospitalization rates remain elevated. In the last four epidemiological weeks, positive cases showed a prevalence of 39.2% for influenza A, 0.8% for influenza B, 45% for other respiratory viruses, 17.7% for rhinoviruses, and 1.6% for SARS-CoV-2 (COVID-19).
Respiratory Virus Prevalence
| Virus | Prevalence (Last 4 Weeks) |
|---|---|
| Influenza A | 39.2% |
| Influenza B | 0.8% |
| other Respiratory Viruses | 45% |
| Rhinoviruses | 17.7% |
| SARS-CoV-2 (COVID-19) | 1.6% |
Understanding Respiratory Viruses: An Evergreen Perspective
respiratory viruses, including influenza, SARS-CoV-2, and RSV, pose ongoing public health challenges globally [[4]]. These viruses primarily affect the respiratory system, causing a range of symptoms from mild cold-like symptoms to severe pneumonia. Factors such as seasonality, population density, and individual immunity influence the spread and severity of these infections. Public health interventions, including vaccination, hygiene practices, and early detection, play a crucial role in mitigating the impact of respiratory viruses on communities.
Frequently Asked Questions About Respiratory Viruses

- Practice good hand hygiene, wear a mask in crowded settings, and get vaccinated against influenza and COVID-19.
- When should I seek medical attention for respiratory symptoms?
- Seek medical attention if you experience difficulty breathing, persistent fever, or worsening symptoms.
