From there, it hitches a ride on other immune cells and is spread through the bloodstream to infect cells in almost all organ systems. The measles virus can be associated with serious side effects and complications, such as pneumonia or encephalitis.
These may be caused by a combination of direct tissue damage from the attacking measles virus, inflammation caused by the immune system trying to fight off the infection, and suppression of the immune system providing an opportunity for bacterial infections. The exact way that the measles virus infection supresses the immune system is not completely understood. Your suppressed immune system leaves you vulnerable to other infections, whether they are germs your body has never encountered before, or something that you would normally already be immune to.
This vulnerability may last from a few months up to three years. As well as being able to cripple your immune system, the infectivity of the measles virus is legendary: up to 9 out of 10 susceptible people will develop measles if they come into contact with an infected person.
A measles-induced cough can easily and efficiently launch lots of viral particles into the air , where they can linger on surfaces for a long time up to two hours, in some cases.
These cells remember past infections and, based on that immunological memory, churn out needed antibodies to thwart reinvading viruses. But it appears the measles caused long term, possibly permanent, losses of a significant portion of previously acquired immunities. This loss of immune memory put the children at a distinct disadvantage should those old bugs circulate again.
So, these findings come as yet another reminder of the public value of measles vaccination. Prior to , when the measles vaccine was developed, 3 to 4 million Americans got the measles each year. As more people were vaccinated, the incidence of measles plummeted. By the year , the disease was declared eliminated from the U. Unfortunately, measles has made a come back, fueled by vaccine refusals.
In October, the Centers for Disease Control and Prevention CDC reported an estimated 1, measles cases in the United States so far in , surpassing the total number of cases reported annually in each of the past 25 years [4]. Around the world, measles continues to infect 7 million people each year, leading to an estimated , deaths. The good news is those numbers can be reduced if more people get the vaccine, which has been shown repeatedly in many large and rigorous studies to be safe and effective.
The CDC recommends that children should receive their first dose by 12 to 15 months of age and a second dose between the ages of 4 and 6. Comprehensive serological profiling of human populations using a synthetic human virome.

Will the NIH be investigating, funding investigation on this? The important thing to know is that SLAM is primarily on immune memory cells. This causes it to use a Trojan horse type mechanism for invasion — When the immune system attempts to clear the virus, the virus instead uses the initial clearance as a back door into the immune system or perhaps better put, as a front door.
When the lymphocytes try to capture it, it turns on them, binds CD on their surface and enters. Once inside, it is able to replicate and then in short order, once amplified, it spreads throughout the whole lymph system and into the bone marrow where it also infects and destroys the long lived antibody producing plasma cells in the bone marrow that store the memory that we were measuring the antibodies. This is what leads to the effects we have noted — initially in population level epidemiological data and now in the immune repertoire itself.
Now, to answer your first question — other viruses have different cellular tropism and do not go after the immune cells directly. Feeling ill and unsure if you should seek medical care? The CDC has published a " coronavirus self checker " where you can answer a series of questions to determine whether you might need further treatment. Follow the fundamentals and help end this pandemic, no matter where you live—get vaccinated ASAP; if you live in an area with low vaccination rates, wear an N95 face mask , don't travel, social distance, avoid large crowds, don't go indoors with people you're not sheltering with especially in bars , practice good hand hygiene, and to protect your life and the lives of others, don't visit any of these 35 Places You're Most Likely to Catch COVID.
