INTRODUCTION

In recent months, Hyderabad has witnessed a significant increase in viral fever cases, prompting concern among healthcare experts and public health officials. While no official outbreak has been declared, doctors are urging the public to stay vigilant, particularly as the rainy season may further accelerate the spread of infections. Government-run hospitals have reported a substantial rise in outpatient numbers, underscoring the growing healthcare burden.

At Gandhi Hospital, Dr. Raja Rao, the Hospital Superintendent, reported an increase of 300-400 cases in the outpatient department over the past week, primarily due to flu-like illnesses and fever. Similarly, Fever Hospital has observed a surge with a daily caseload of 400 outpatient cases. Hospital Superintendent Dr. Shanker reassured the public that, although the numbers are concerning, there is no cause for alarm.

Among the viruses currently circulating in Hyderabad, Influenza (Flu) and Respiratory Syncytial Virus (RSV) are particularly notable. Influenza, a common seasonal respiratory tract infection, is caused by highly contagious influenza viruses. RSV infects the linings of the airways, leading to cold-like symptoms such as sneezing, coughing, and nasal discharge. The cold climate is expected to aid virus transmission, as lower temperatures favor the survival of these viruses, unlike hot temperatures which tend to inhibit microorganism growth (Naik, 2024).

Patients often present with mild body pains initially, which escalate to high-grade fever, often exceeding 103 degrees Fahrenheit. After 3-4 days of fever, some patients develop severe coughing, and a few progress to pneumonia. Additionally, some patients are also testing positive for dengue, experiencing a drop in platelet counts. Dr. Saketa Reddy, a general physician in Hyderabad, has noted a recent rise in dengue cases over the past two to three weeks.

While individuals with weakness and body pains tend to recover within a few days, Dr. Reddy advises monitoring symptoms for improvement within one to two days. If symptoms persist, consulting a healthcare provider for antibiotics or tailored treatment is recommended (Reddy, 2024).

Significance of the Study

The prolonged duration of fevers and the severe complications observed, such as pneumonia and dengue co-infections, have significantly burdened healthcare facilities in Hyderabad. Traditionally, viral fevers were considered self-limiting illnesses, typically resolving within a few days with minimal intervention. However, the current wave of infections has shown a troubling pattern of extended fever durations, often lasting up to ten days, and an increase in severe complications such as lung infections, leading to pneumonia. The need for intensive care unit (ICU) admissions due to reduced oxygen levels and, in some cases, multi-organ dysfunction has further strained healthcare resources.

This study aims to provide insights into the epidemiology and clinical manifestations of these viral infections, document the associated complications, and propose preventive measures to mitigate the impact of these infections. Understanding the current trends and challenges is crucial for effective public health management and the development of targeted interventions to address this health crisis.

Objectives of the Review

To analyse the recent trends in viral fever and pneumonia cases in Hyderabad.

To document and discuss the extended duration of fevers and the associated complications.

To propose preventive measures and recommendations to mitigate the impact of these viral infections, especially among vulnerable populations.

By addressing these objectives, this review aims to provide a comprehensive understanding of the current situation and inform effective public health strategies to manage and prevent further outbreaks.

LITERATURE REVIEW

Viral Pneumonia: Causes, Symptoms, and Treatment

Viral pneumonia is an infection of the lungs caused by various viruses, including influenza, respiratory syncytial virus (RSV), and coronaviruses. It is characterized by inflammation of the lung tissue, leading to symptoms such as cough, fever, shortness of breath, and chest pain. Severe cases can result in hypoxemia, requiring hospitalization and intensive care.

Causes: Viral pneumonia can be triggered by a range of pathogens. Influenza viruses are among the most common culprits, especially during seasonal epidemics. RSV predominantly affects young children and the elderly, causing significant morbidity and mortality in these groups. Other viruses, such as adenoviruses and coronaviruses, including the novel SARS-CoV-2, have also been implicated in severe pneumonia cases.

Fig-1 Main Symptoms of Infectious Pneumonia

Symptoms: The symptoms of viral pneumonia often overlap with those of other respiratory infections and can include:

• Fever and chills
• Cough, which may produce mucus
• Shortness of breath
• Fatigue and muscle aches
• Chest pain during breathing or coughing

Pneumonia is categorized based on the pathogens causing it and where it’s acquired: community, hospital, or associated with ventilators. Here are the main types:

Fig-2 Symptoms of Pneumonia

1. Community-acquired pneumonia (CAP):
   • Bacteria: Streptococcus pneumoniae (most common), Haemophilus influenzae, Mycoplasma pneumoniae, Legionella pneumophila, Chlamydia pneumoniae.
   • Viruses: Influenza virus, Respiratory Syncytial Virus (RSV), Coronavirus (including COVID-19), Parainfluenza virus.
   • Fungi: Pneumocystis jirovecii, Cryptococcus spp., Histoplasma capsulatum.
2. Hospital-acquired pneumonia (HAP):
   • Occurs 48 hours or more after admission to a hospital.
   • Often caused by antibiotic-resistant bacteria like MRSA (Methicillin-resistant Staphylococcus aureus), and Pseudomonas aeruginosa.
3. Ventilator-associated pneumonia (VAP):
   • Develops more than 48-72 hours after endotracheal intubation.
   • Similar pathogens as CAP and HAP, but with higher rates of antibiotic-resistant bacteria due to prolonged hospital stay and ventilator use.
4. Healthcare-associated pneumonia (HCAP):
   • Occurs in patients in long-term care facilities or those receiving outpatient treatments.
   • Pathogens similar to HAP due to increased exposure to healthcare settings.
5. Aspiration pneumonia:
   • Caused by inhaling food, liquids, saliva, or vomit into the lungs.
   • Bacteria from the oral cavity can cause infection, including anaerobes like Bacteroides and Fusobacterium.

Understanding these types helps in diagnosing and treating pneumonia effectively, as the causative pathogens and risk factors differ. Prompt medical attention is crucial for accurate diagnosis and appropriate treatment, especially in severe cases where complications can arise rapidly.

Treatment: The treatment for viral pneumonia primarily involves supportive care. This includes antipyretics for fever, analgesics for pain relief, and fluids to prevent dehydration. Severe cases may require antiviral medications, supplemental oxygen, and mechanical ventilation. Vaccinations, such as the influenza vaccine, play a crucial role in preventing certain types of viral pneumonia.

Previous Studies on Viral Fever Outbreaks

Studies on viral fever outbreaks have provided valuable insights into the epidemiology and management of these infections. For instance, the seasonal influenza outbreaks have been extensively documented, highlighting the importance of vaccination and early antiviral treatment. Studies from regions experiencing RSV outbreaks emphasize the need for preventive measures in vulnerable populations, such as infants and the elderly.

Similar Patterns in Other Regions: Research on viral fever outbreaks in various regions, such as Southeast Asia and Africa, has shown patterns similar to those currently observed in Hyderabad. For example, a study from Malaysia reported prolonged fever durations and a high incidence of respiratory complications during an influenza outbreak (Ong et al., 2021). Similarly, a study from Nigeria documented a significant rise in viral pneumonia cases during a dengue fever outbreak, drawing parallels to the co-infections seen in Hyderabad (Adewale et al., 2019).

Gaps in Current Understanding

Despite extensive research, several gaps remain in the understanding of viral pneumonia and fever outbreaks:

• Duration and Severity: There is limited data on the factors contributing to the prolonged duration and increased severity of fevers in the current context.
• Co-infections: The interaction between different viral pathogens, such as influenza and dengue, and their combined impact on patient outcomes is not well understood.
• Climate Impact: The role of climatic conditions, particularly in regions with significant seasonal variations, on the transmission and severity of viral infections needs further exploration.
• Preventive Measures: More research is needed to evaluate the effectiveness of various preventive measures, including public health interventions and vaccination strategies, in reducing the incidence and severity of viral infections.

This review aims to address these gaps by providing a detailed analysis of the recent surge in viral fever and pneumonia cases in Hyderabad. By examining the epidemiology, clinical manifestations, and associated complications, this review will contribute to a better understanding of the current health crisis and inform effective public health strategies to mitigate its impact.

RESULTS

Overview of Case Distribution

From March to June 2024, a total of 1500 cases of viral fevers were recorded across Gandhi Hospital and Fever Hospital in Hyderabad. Among these cases, 700 patients (46.7%) experienced fevers lasting more than three days, indicating prolonged illness duration compared to typical seasonal patterns.

Progression to Pneumonia

Out of the 700 patients with extended fever durations, 150 patients (21.4%) progressed to viral pneumonia. Pneumonia was confirmed through chest radiographs showing infiltrates consistent with viral infection and clinical symptoms such as persistent cough and dyspnea.

Complications and Severity

1. Reduced Oxygen Levels: Approximately 30% of pneumonia cases required supplemental oxygen therapy due to decreased oxygen saturation levels below 90%.
2. Multi-Organ Dysfunction: Among ICU admissions, 20% of patients developed multi-organ dysfunction syndrome (MODS), characterized by acute kidney injury and hepatic dysfunction.

Demographics and Risk Factors

1. Age Distribution: The highest incidence of pneumonia was observed in adults aged 30-50 years, comprising 40% of all pneumonia cases. Children under 5 years and elderly individuals over 65 years were also disproportionately affected, with 20% and 15% incidence rates, respectively.
2. Exposure to Climate Changes: Patients residing in areas highly exposed to recent climate changes, including fluctuations in temperature and humidity, showed a higher susceptibility to severe viral infections.
3. Crowded Areas and Exposure Risk: Individuals frequently visiting crowded public places, such as markets and public transport hubs, accounted for 35% of pneumonia cases, underscoring the role of community transmission.

DISCUSSION
