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 truth of infectious diseases. These diseases, caused by microscopic pathogenic agents like bacteria, viruses, fungi, and parasites, can very quickly spread among you. Dr Dhaval shah will discuss how infectious diseases transmit from person to person.
It's All In The Touch
Each and every day, you come into physical connection with many people. A pat on the rear, an agreeable handshake, or a relaxing hug can all unknowingly spread pathogens. This kind of transmission, often called direct contact happens when an individual 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 steadfastly keep up personal hygiene by regular handwashing to break the chain of transmission.
Watch That Cough!
Another common way for diseases to spread is through the respiratory droplets expelled when an infected individual talks, coughs, or sneezes. These droplets can retain 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 danger, it's recommended to wear a mask and maintain adequate physical distance from sick persons or if you're feeling unwell.
Blood Transfusions and Beyond
It will 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 which can 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 usually acquired by inhaling spores from the environment while parasites could be transmitted during outdoor journeys by insect vectors. Wearing protective gear during outdoor activities, using bug repellents, and adopting preventive measures can help.
