Who Is Susceptible To MRSA Infection?

default
Posted on Fri, 20 Nov 2015
Question: Hello !
I have some more question about MRSA !
I read one material about MRSA as I understand form hospital strain travel to community

Following antibiotic susceptibility testing, pulsed-field gel electrophoresis, Panton-Valentine leukocidin gene detection and SCCmec element assignment, 95% of the isolates were shown to be related to hospital epidemic strains EMRSA-15 and EMRSA-16.
Transmission of MRSA from the hospital setting into the surrounding community population, as demonstrated by this study, warrants the need for targeted patient screening and decolonisation in both the clinical and community environments.
XXXX

These strains are more better surviving and transmitting in community EMRSA-15 and EMRSA-16? or in this case people with weak immune system transmit to people with week immune system ?

Brief Answer:
Just the weak population is more susceptible to these strains

Detailed Answer:
Hello once again sir.

I hope you have been well.

Yes, these strains are transmitted from weak individuals to other weak individuals in the community. Mainly by the term mentioned:

Transmission of MRSA from the hospital setting into the surrounding community population, as demonstrated by this study, warrants the need for TARGETED patient screening and decolonisation in both the clinical and community environments.

And these are studies that are in depth of course, but not really researched in detail in my opinion. And sufficient data which has to be quite a lot is not present to put these forwards and pass them out to all doctors for better understanding on the topic.

Please do not hesitate to write back to me for any help, not just about MRSA; I am always here to help.

Best wishes.

Thank you !!!
There is still some questions
The article about veterinary info
Who is at risk to acquire MRSA? Health care workers are at the highest risk of becoming colonized with MRSA. Approximately 63% of MRSA infections are categorized as HA-MRSA cases. The remaining cases are split between healthy individuals who acquire the bacteria through their everyday environment and individuals involved in the animal industry, most commonly those involved in the veterinary field
XXXX
They are talking about veterinary who has some risk – and 63% are animals who has got HA MRSA and other part of statistic is CA MRSA in animals is so ?
And as you said healthy people are low risk for HA MRSA – so healthy veterinaries are low risk of HA MRSA ? is it so ?

Brief Answer:
"63% are animals who ..." not in animals sir, in humans

Detailed Answer:
Hi sir.

They are saying that out of all the MRSA infections in humans, 63 % of them are hospital acquired (coming from the hospital), and the remaining come from either:

+Acquired through the daily environment

or

+Acquired by individuals working in the animal industry (most of these individuals are who get the infection are working in the veterinary field)


Healthy vets are indeed at a low risk of acquiring HA-MRSA, but if they are exposed to the infection-causing organism on a daily basis, and on any one of these occasions their immunity is low due to various reasons, then they can acquire it.

I hope this is clear sir, they are speaking about humans and not animals, may be you misunderstood that part.

Thank you very much !
Your answers are very good so answer in shortly

So if im in good health and i get CA MRSA skin infection – and i get early to treat it is low possibility that i will need hospitalization
So avoid hospitalization from CA MRSA skin infection is important to keep good health, is it so ?

Again you can answer me shortly
In one material I read about hospital infection death rate and it was said
The estimated deaths associated with HAIs in U.S. hospitals were 98,987: of these, 35,967 were for pneumonia, 30,665 for bloodstream infections, 13,088 for urinary tract infections, 8,205 for surgical site infections, and 11,062 for infections of other sites.
XXXX

As I understand invasive infection are risk, but there is surgical site infections that cause death (8,205 for surgical site infections ) – how and why they cause death.
As we discussed better immunity less chance of invasive hospital infection !

Answered by Dr. Shoaib Khan (2 hours later)
Brief Answer:
There can be many factors causing surgical site infections-death

Detailed Answer:
Hello once again sir.

Surgical site infections are quite often encountered, I myself am a surgeon and encounter at least 1 surgical site infection in a about 2 weeks. This usually takes place either due to some pre-existing chronic condition (e.g. diabetes: which does not allow adequate healing), or just bad luck. We go about the same process of washing, prepping, etc; before any surgery, but 1 in 30 patients can get infected due to various reasons.

But not all these patients who get infected die, there will be some patients who have a lowered immunity, or as I said some pre-existing condition (e.g. age, chronic conditions, etc.) which prevents them from healing or recovering adequately, resulting in their demise.

Yes, better immunity carries a lower risk of invasive hospital infections.

Short answers are very good

So basically any kind of hospital infection could be bad for those who have bad condition ! not only HA MRSA

Bad condition + hospital infection even not invasive is risk for bad outcome

But strong immunity + hospital infection + treatment will be OK !!

Is it so ?

Thank you for your answers
And still you can answers shortly

1.     How long HA MRSA can live on surface ( as it is fragile)
I have HA MRSA on my skin or my clothes – and I get home how long it can survive on such surface?
2.     If it is on my skin and I’m healthy - other bacteria will overcome it ?

3.     There was one material about CA MRSA and HA MRSA in children’s – and it was said
Risk factors associated with methicillin-sensitive S aureus colonization included pet ownership, fingernail biting, and sports participation.
XXXX
Understan pets could be colinezed with CA MRSA – but HA MRSA coloization in heathy pets is very low risk. So heathy pets are very low riks for HA MRSA colinization a transmition. Is it so ? And it was writen down wihout expletion.

Brief Answer:
Sorry for the delay sir

Detailed Answer:
Hi sir.

1. HA MRSA can survive on any surface for hours, days and even months. Which is why it is important to wash yiur hands and also maintain good hygiene

2. I do not understand what you mean by other bacteria overcoming the HA MRSA if it is on your skin. If it is on your skin, then you will have to clean the region well enough to avoid getting infected.

But of course you will not know when it is on your skin, which is why maintaining good hygiene is important.

3. The reason why pets are a source is because although you maintain good hygiene, your pet can carry the pathogen on their bodies. A pet cannot be cleaned on a daily basis (cannot be showered daily), and so even if you maintain good hygiene, the pet can carry the pathogen and either directly come in contact with an individual or come in contact with objects that are in direct contact with the individual.

But yes, colonisation and transmission of HA MRSA in healthy pets is low. It is low because as a precautionary measure, most pet owners are advised to give their pets a shower immediately after any direct or indirect contact with a hospital, and also because pets are very rarely in contact with hospitals or its staff.

I hope this makes things better. Unfortunately, these questions could not be passed off without an explanation and so I could not give you short answers sir.

Best wishes.
