what of the following links in the chain of infection is considered the weakest?
234497
The means of transmission is the weakest link in the chain of infection, and it is the only link we can hope to eliminate entirely. Most infection control efforts are aimed at preventing the transport of germs from the reservoir to the susceptible host.

The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.

An IgG dimer is the smallest possible immune complex (containing two IgG molecules) and therefore the least effective in cross-linking multiple Fc receptor molecules.

The chain of infection, if we think of it as an actual chain, is made up of six different links: pathogen (infectious agent), reservoir, portal of exit, means of transmission, portal of entry, and the new host.

More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection. Figure 1.19 Chain of Infection.

The commonest route of transmission is usually secondary to ingestion of the infected material along with associated intestinal TB. Hematogenous route of transmission and contiguous spread from adjacent affected abdominal organ can also occur.

Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).

The link can be broken through hand washing, safe sex practices, or avoiding contact with infected individuals. Link number five is the portal of entry. Entry of the pathogen can take place in one of three ways: penetration, inhalation, or ingestion.

Infection. With a low white blood cell count and, in particular, a low level of neutrophils (neutropenia), a type of white blood cell that fights infection, you're at higher risk of developing an infection. And if you develop an infection when you have a low white blood cell count, your body can't protect itself.

Leukopenia: A low white blood cell count. A decrease in the production of functional leukocytes (white blood cells) weakens the body's immune defense, which may make you more prone to infections. Thrombocytopenia: A low blood platelet count. Platelets are the blood cells responsible for blood clotting.

Prevent contact by proper hand washing, disinfection/sterilization techniques, isolation of infected patients, and not working when contagious. Way to bread chain at Portal of Entry, make sure ports of entry are not subjected to pathogens by covering them.

Because the bacteria in the vaccine is weak, it triggers the immune system to protect against the disease. This gives good immunity to people who receive it without actually causing the disease. The vaccine is 70 to 80% effective against the most severe forms of TB, such as TB meningitis in children.
