Influenza-like illness (ILI), also known as flu-like syndrome/symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms.
It is a serious, contagious disease. It is spread by respiratory drops which occur when someone coughs, sneezes, or talks. It is also spread if someone touches something wet with respiratory droplets and then touches their eyes, nose, or mouth.
ILI can be caused by RSV, Malaria, Acute HIV/AIDS infection, Herpes, Hepatitis C, Lyme disease, Rabies, Myocarditis, Q fever, dengue fever, poliomyelitis, pneumonia, measles, SARS, COVID-19, and many others.
Sometimes certain pharmaceutical drugs, chemotherapeutic agents as well as some vaccines can also cause ILI.
Influenza causes the abrupt onset of fever, all over body aches, and, sometimes, a dry cough, a mild runny nose, sore throat or nausea. Fever from influenza lasts from 3 to 7 days. During this time, it is important that you isolate yourself to keep from spreading the infection to others.
People with certain health conditions are at risk for more serious sickness from influenza. If you have any of the following conditions you should speak with your health care provider about your illness: asthma, diabetes, pregnancy, heart disease, and diseases which make the immune system weak the flu can be very serious.
ILI can affect the body at different levels. Hence certain lab tests can help in assessing overall health of an individual, during influenza like illness conditions.
|Test Name||Test Parameter||Importance|
|C-Reactive Protein (CRP)||CRP||To assess if you have an acute condition causing inflammation, such asa serious bacterial or viral infection or when you are suffering from an inflammatory disorder|
|CBC (Complete Blood Count)||WBC Count||WBCs (White Blood Cells) form the main defense mechanism of the body. Their numbers get deranged in the body in cases of infections and also have a role in inflammation, and allergic reactions|
|CBC (Complete Blood Count)||Lymphocyte Count||Lymphocytes are primarily involved in the body's immune response mechanism. Their levels indicate the body's preparedness to fight infections|
|CBC (CompleteBlood Count)||Platelet Count||Platelets help in the blood clotting mechanism of the body. Their levels decrease in cases of infections and inflammations.|
|SGPT||Liver Enzymes||SGPT (ALT) helps in analyzing health of the liver. If their levels are increased, then it indicates damage to liver.|
|Sr Ferritin||Ferritin||A ferritin test helps your doctor understand how much iron your bodystores. Increased levels indicate liver disease or inflammatory conditions|
|Sr Creatinine||Creatinine||A creatinine test reveals important information about your kidneys. If your kidneys aren't functioning properly, an increased level of creatinine may accumulate in your blood.|
|Erythrocyte Sedimentation Rate (ESR)||ESR||To detect the presence of inflammation in the body|
