Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.
Direct contact. An easy way to catch most infectious diseases is by coming in contact with a person or an animal with the infection. Infectious diseases can be spread through direct contact such as: Person to person.
People are usually infected through direct skin contact with water, moist soil, or vegetation contaminated with urine from infected animals. Other ways of transmission are direct contact with body tissues of infected animals or ingesting food contaminated with urine. Transmission from person to person is rare (3).
Direct contact spread
Some infections can be spread by direct contact with the infected area to another person's body, or via contact with a contaminated surface. This is the most common route of cross-infection from one person to another (transmission of infection).
Washing hands properly is one of the most important and effective ways of stopping the spread of infections and illnesses. Wash your hands thoroughly using water and plain soap.
"Big Three" Infectious Diseases: Tuberculosis, Malaria and HIV/AIDS.
The most common causes are viruses, bacteria, fungi and parasites. Infectious diseases usually spread from person to person, through contaminated food or water and through bug bites. Some infectious diseases are minor and some are very serious.
Staphylococcus aureus (MRSA)
Probably the most famous hospital-acquired infection or 'superbug', MRSA is so-called because of its resistance to the antibiotic methicillin (hence Methicillin Resistant Staphylococcus Aureas).
The most deadly bacterial disease contracted by human beings is mycobacterium tuberculosis, the world's leading infectious disease with more than 1,700,000 deaths per year. As much as 13% of cases are resistant to most antibiotics, and about 6% are resistant or unresponsive to essentially all treatment.
Sepsis is the body's extreme response to an infection. It is a life-threatening medical emergency. Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Infections that lead to sepsis most often start in the lung, urinary tract, skin, or gastrointestinal tract.
cancer. dementia, including Alzheimer's disease. advanced lung, heart, kidney and liver disease. stroke and other neurological diseases, including motor neurone disease and multiple sclerosis.
Some repeat infections, like pneumonia and bladder infections, may happen because of a genetic predisposition. That's an inherited tendency to get more infections than most people do. Structural issues. Repeat infections can also happen as a result of how your body is put together.
Take action and practice hand hygiene often. Use soap and water or an alcoholbased hand rub to clean your hands. It only takes 15 seconds to practice hand hygiene.
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
The mode of transmission can include direct contact, droplets, a vector such as a mosquito, a vehicle such as food, or the airborne route.
Rabies. Rabies, one of the oldest known infectious diseases, is nearly 100% fatal and continues to cause tens of thousands of human deaths globally (1).
Ischemic heart disease, or coronary artery disease
The deadliest disease in the world is coronary artery disease (CAD). Also known as ischemic heart disease, CAD occurs when the blood vessels that supply blood to the heart become narrowed. Untreated CAD can lead to chest pain, heart failure, and arrhythmias.
Perhaps the most notorious of all infectious diseases, the bubonic and pneumonic plagues are believed to be the cause of the Black Death that rampaged through Asia, Europe and Africa in the 14th century killing an estimated 50 million people.
The aminoglycosides, in particular gentamicin, are the most toxic of the antibiotics commonly used in ophthalmology. Extreme caution should be used when administering a periocular injection of aminoglycoside for treatment or prophylaxis of infection.
