Whatâs the recovery like from a bacterial infection?
Madonna is now likely to be continuing to rest at home, now that she has been discharged from hospital.
It is not clear what initially caused Madonna's infection, but doctors said it became extremely serious and required treatment in intensive care.
Infections can develop into a life-threatening condition called sepsis or blood poisoning.
Certain types of bacteria can pose a threat if they enter the body or bloodstream, via a cut or bug bite or contaminated food, for example, or if bacteria begins multiplying in a part of the body where it’s not meant to be.
Bacterial infections can potentially affect any part of the body, including the skin, blood, brain and lungs.
Symptoms could be a raised temperature and violent shivering and shaking.
But when things escalate and your cardiovascular system is compromised, this will put you at risk of sepsis.
Most bacterial infections can be treated with antibiotics that can be taken at home, according to Dr Sunny Jutla, a specialist digital clinician at Medichecks and consultant in emergency medicine.
“But if you develop sepsis, you need to be treated in a hospital. In this case, you would receive IV antibiotics and fluids.
"Patients that are incredibly unwell would also need to be admitted to intensive care, where they would receive multi-organ support,” Jutla added.
With the correct and prompt treatment for sepsis, there is a very good chance of survival.
However, still around one in five people who develop sepsis will not survive, which is why getting appropriate medical help as quickly as possible is vital.
And for people who do survive, there can be long term after-effects too.
This can include cognitive dysfunction, like brain fog.
Dr Ron Daniels, an intensive care doctor, said: "There are also physical problems, most commonly fatigue, lack of ability to exercise, brittle nails and hair and even psychological consequences including PTSD.”
This may be referred to as ‘post sepsis syndrome’.
