Transmission of infectious diseases from mother to baby is also a concern at the time of birth when the baby passes through the birth canal. Babies whose mothers have active chlamydia or gonorrhea infections may be exposed to the causative pathogens in the vagina, which can result in eye infections that lead to blindness. To prevent this, it is standard practice to administer antibiotic drops to infants’ eyes shortly after birth. A pathogen’s portal specificity is determined by the organism’s environmental adaptions and by the enzymes and toxins they secrete.
Treating the common cold
“Condom use can help you avoid herpes simplex and syphilis transmission,” says Hasbun. It’s also important to wear repellent when outdoors and to avoid the insects that can spread it, advises Sellick. Many things can be a contagion or communicable disease that is passed through disease transmission. Contagion effects can be spread through bitbuy review bacterium, direct cause, flu, the transmission of an infectious disease, scarlet fever, AIDS patients, exposure to influenza, . Emotional contagion is the spread of a behavior pattern such as by imitation, harmful influence, doctrine, rumor or propaganda. An acute contagious infection can spread easily and inflame the throat and air passages., or distinct red spots and purulent skin eruptions.
“Tuberculosis is another cause of meningitis, but tuberculous meningitis is rare in the United States,” says Dr. Rodrigo Hasbun, an infectious diseases professor at the University of Texas McGovern Medical School. Parasitic meningitis can be caused by a tapeworm infection in the brain or by cerebral malaria. Rarely, an amoeba that lives in certain bodies of freshwater can enter the nose and travel to the brain. Your body’s brain and spinal cord are surrounded by three layers of membranes known as the meninges. These protective membranes are vital for providing structural support, cushioning tissue, improving circulation of cerebrospinal fluid and enhancing immune health by providing a defensive barrier against disease.
- By entering the host cells, intracellular pathogens are able to evade some mechanisms of the immune system while also exploiting the nutrients in the host cell.

These include the Hib, MenB, MenACWY and PCV15 and PPSV23 vaccines, says Hasbun. Bacterial meningitis differs from viral meningitis as it’s the least common but most dangerous type of meningitis. About one in six people who get it die, and one in five suffer severe complications, per the World Health Organization.

- The common cold, on the other hand, can be infectious from a few days before symptoms appear until all of the symptoms have disappeared.
- Although phagocytosis allows the pathogen to gain entry to the host cell, in most cases, the host cell kills and degrades the pathogen by using digestive enzymes.

English language antonyms are also very useful grammatical devices to know. This list of antonyms for the word contagion is also provided by Power Thesaurus. An influenza epidemic turned into a deadly pandemic in 1918, when it spread around the globe.
The common cold, on the other hand, can be infectious from a few days before symptoms appear until all of the symptoms have disappeared. An infected person is usually most contagious during the first two to three days of a cold, when symptoms are the worst. For most kinds of host cells, pathogens use one of two different mechanisms for endocytosis and entry. One mechanism relies on effector proteins secreted by the pathogen; these effector proteins trigger entry into the host cell. This is the method that Salmonella and Shigella use when invading intestinal epithelial cells.
According to Etymonline, the word contagion has been used since the Middle English contagioun. It comes from Middle French and Old French, as well as the Latin contingere, a variant stem of tangere, the Latin contāgiōn, Latin contāgiō/Latin contagio and the stem of contāgiō. “There is always that risk of some sort of contagion between the private security companies, the types of people they employ, and their desire to continually maintain their contract,” Mr Smith says.

May then gain access to the bloodstream and make their way to other locations in the body, resulting in a secondary infection. Bacterial meningitis is caused by bacteria entering the bloodstream and traveling to the meninges. Other times, this bacterial can enter the meninges directly due to a head injury or ear or sinus infection. Active immunity means one’s body produces antibodies to fight off the virus or another disease-causing agent. This happens after a specific disease is introduced to the body, whether through previous infection or a vaccine. This immunity usually is permanent and will last a person’s entire life.

In some cases, contagious diseases can become an epidemic or even a pandemic. An epidemic is a sudden disease outbreak that affects a large number of people in a particular region, community, or population. In an epidemic, the number of people affected by the disease is larger than what is normally expected. A pandemic is a disease epidemic that has spread to a large group of people across a large region, multiple nations, or continents. In a focal infection, a localized pathogen, or the toxins it produces, can spread to a secondary location. For example, a dental hygienist nicking the gum with a sharp tool can lead to a local infection in the gum by Streptococcus bacteria of the normal oral microbiota.

Passive immunity means the antibodies were transferred from one person to another, like from mother to baby through the placenta or breastfeeding.
Fecal-oral transmission can also occur if an infected person doesn’t wash their hands and then contaminates surfaces. At the same time, not all forms of viral meningitis are contagious or spread easily. “West Nile Virus is transmitted by mosquito bites and not by human-to-human contact and the herpes simplex virus is only transmitted by unprotected sex,” says Hasburn.
Bacteria such as Mycobacterium tuberculosis, Legionella pneumophila, and Salmonella species use a slightly different mechanism to evade being digested by the phagocyte. These bacteria prevent the fusion of the phagosome with the lysosome, thus remaining alive and dividing within the phagosome. There are multiple types of meningitis, which are typically classified by their cause.
