Common Airborne Diseases During Rainy Season

What Diseases are Airborne?

During the rainy season, several airborne diseases become more prevalent. Knowing how these diseases are transmitted forms the basis for effective prevention. Here are some of the common airborne disease names prevalent during this time —

1. Common Cold

◦ Caused by various viruses, primarily rhinoviruses, this infection is propagated by respiratory droplets whenever an infected individual coughs or sneezes. It also spreads by touching contaminated surfaces

◦ Symptoms:

- Runny or stuffy nose

- Sore throat

- Cough

- Mild fatigue

◦ Preventive measures:

- Regular handwashing

- Avoiding close contact with infected individuals

- Maintaining good indoor ventilation

2. Influenza (Flu)

◦ Caused by influenza viruses, this infection is highly contagious and spreads through respiratory droplets. The virus can survive on surfaces for several hours, resulting in indirect transmission

◦ Symptoms:

- High fever

- Body aches

- Fatigue

- Dry cough

◦ Preventive measures:

- Annual flu vaccination

- Practicing good respiratory hygiene (covering mouth and nose when coughing or sneezing)

- Staying home when feeling unwell

3. Tuberculosis (TB)

◦ Caused by a bacterium called Mycobacterium tuberculosis. This airborne disease spreads when an infected person coughs, speaks, or sneezes, releasing bacteria into the air which can stay suspended for many hours in the air, particularly in poorly ventilated areas.

◦ Symptoms:

- Persistent cough (lasting more than three weeks)

- Chest pain

- Weight loss

- Night sweats

◦ Preventive measures:

- Early detection and treatment of active cases

- Improving ventilation in indoor spaces

- Wearing appropriate protective equipment in high-risk settings

4. Pneumonia

◦ Caused by various species of bacteria, viruses, or fungi. Bacterial pneumonia, is an airborne disease caused by a bacterium, Streptococcus pneumoniae. It is transmitted through droplets via coughing or sneezing and by direct contact with the infected patient.

◦ Symptoms:

- Chest pain when breathing or coughing

- Fatigue

- Fever and chills

- Shortness of breath

◦ Preventive measures:

- Maintaining good overall health

- Avoiding smoking and excessive alcohol consumption

- Practicing good hand hygiene

5. Legionnaires' Disease

◦ Caused by Legionella bacteria, this infection spreads through inhalation of contaminated water droplets. The condition is often associated with poorly maintained air conditioning systems or water sources

◦ Symptoms:

- High fever

- Cough (may be dry or produce mucus)

- Shortness of breath

- Chest pain

◦ Preventive measures:

- Regular maintenance of air conditioning systems and water sources

- Avoiding stagnant water

- Proper cleaning and disinfection of water systems

Treatment

Treatment options vary depending on the airborne disease and its severity. Here are some general points to consider —

1. Rest and hydration:

Most people diagnosed with airborne illnesses benefit from adequate rest and increased fluid intake

2. Symptom management:

Over-the-counter remedies may help alleviate symptoms like fever, congestion, or cough. It's important to follow recommended dosages and consult a healthcare professional when unsure

3. Antibiotics:

Only effective for bacterial infections, not viral ones. Take as prescribed by the doctor.

4. Antiviral medicines:

May be prescribed for certain viral infections like influenza. They are most effective if started early in the course of illness

5. Supportive care:

In severe cases, hospitalisation may be necessary for supportive treatments like oxygen therapy or intravenous fluids

6. Follow-up care:

Regular check-ups may be necessary to monitor recovery and prevent complications

FAQs

1. What are the most common airborne diseases during the rainy season?

Common airborne diseases during this time include the common cold, influenza, pneumonia, and, in some regions, tuberculosis.

2. How can I differentiate between a common cold and the flu?

While symptoms can be similar, the flu typically comes on more suddenly and is often accompanied by higher fever, more severe body aches, and greater fatigue compared to a common cold.

3. Are all respiratory infections airborne diseases?

Not all respiratory infections are airborne. Some spread through direct contact or contaminated surfaces. However, many common respiratory infections are indeed airborne.

4. Can airborne diseases be completely prevented?

While it's difficult to prevent exposure to airborne diseases completely, the risk can be significantly reduced through good hygiene practices, proper ventilation, and other preventive measures.

5. How long do airborne pathogens typically survive in the air?

The survival time of airborne pathogens varies greatly depending on the specific pathogen and environmental conditions. Some can survive for only a few seconds, while others may remain infectious for hours.
