"Big Three" Infectious Diseases: Tuberculosis, Malaria and HIV/AIDS.
Viral infections are any illness you get from a virus (a small germ that uses your cells to reproduce). Common viral illnesses include colds, the flu, COVID-19, norovirus (“stomach flu”), HPV (warts) and herpes simplex virus (cold sores).
Person to person spread. This is the most common way that we get an infectious disease. Germs can spread from person to person through: the air as droplets or aerosol particles.
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.
What Is Infection? Infection occurs when germs enter the body and multiply, causing disease and illness. Different kinds of pathogens, a fancy term for germs, cause different types of sickness and disease. They come in four types – viruses, bacteria, fungus, and parasites.
Methicillin-Resistant Staphylococcus Aureus
This type of bacteria is resistant to many antibiotics, including methicillin. Most methicillin-resistant Staphylococcus aureus, or MRSA, infections contracted outside of a hospital are skin infections.
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.
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.
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.
1. The Black Death: Bubonic Plague. The Black Death ravaged most of Europe and the Mediterranean from 1346 until 1353. Over 50 million people died, more than 60% of Europe's entire population at the time.
A viral infection usually lasts only a week or two. But when you're feeling rotten, this can seem like a long time! Here are some tips to help ease symptoms and get better faster: Rest.
Bacteria, viruses and fungi can show up in body fluids, such as blood, urine (wee), faeces (poo), sputum (spit), cerebrospinal fluid (CSF) bone marrow and skin cells.
Through droplets and particles that are breathed out by someone who has the infection. You might breathe in the droplets or particles, or they could land on your mouth, nose, or eyes. By touching surfaces or objects that have the virus on them and then touching your mouth, nose, or eyes.
Medicine that treats viral infections is called an antiviral. These medicines usually stop a virus from making copies of itself. They also may stop a virus from going into or leaving a cell. Many antivirals are made to target the virus and not the host cell.
Though various bacteria, viruses, and fungi can all cause nosocomial infections, the most common is the bacterium Staphylococcus aureus.
Type 1 or type 2 diabetes can increase your risk of serious COVID-19 symptoms. Having a higher body mass index that's considered overweight, obese or severely obese also increases this risk. Diabetes and obesity both reduce how well a person's immune system works. Diabetes increases the risk of infections in general.
