Dr Dhaval shah: Understanding Person-to-Person Transmission of Infectious Diseases

Catching a typical cold from someone or contracting a contagious illness opens you around the reality of infectious diseases. These diseases, brought on by microscopic pathogenic agents like bacteria, viruses, fungi, and parasites, can easily spread among you. Dr Dhaval shah will discuss how infectious diseases transmit from person to person.

It’s All In The Touch

Every single day, you come right into physical contact with many people. A pat on the rear, an agreeable handshake, or a reassuring hug can all unknowingly spread pathogens. This type of transmission, often known as direct contact happens when a person comes in contact with the secretions of an infected person, typically through touching.

Diseases like skin infections, warts, and even some respiratory infections spread this way. It’s crucial, therefore, to maintain personal hygiene by regular handwashing to break the chain of transmission.

Watch That Cough!

Another common means for diseases to spread is through the respiratory droplets expelled when an infected individual talks, coughs, or sneezes. These droplets can support the pathogen and be breathed in by others, resulting in new infections.

For example, influenza and the novel coronavirus, SARS-CoV-2, primarily spread in this manner. To mitigate the risk, it’s recommended to wear a disguise and maintain adequate physical distance from sick persons or if you’re feeling unwell.

Blood Transfusions and Beyond

It would surprise some, but certain infectious diseases can spread through the exchange of blood and other body fluids, usually during blood transfusions, organ transplants, sharing injection needles, or through sexual contact. HIV and hepatitis B are two such diseases that may be transmitted in this manner.

Regulated screening processes for transfusions or organ transplants promoting safe sex practices and careful disposal of needles can significantly reduce such transmissions.

Dangerous Flora and Fauna

Fungal infections are generally acquired by inhaling spores from the environment while parasites may be transmitted during outdoor journeys by insect vectors. Wearing protective gear during outdoor activities, using bug repellents, and adopting preventive measures can help.
