Viral Infection
Sat Jul 08 2023
Influenza A Virus subtype H3N2 is defined as a subtype of virus that causes Influenza. H3N2 viruses usually affect birds and mammals. This virus has mutated into multiple strains in humans, birds and pigs. This is a respiratory viral infection that causes health problems every year.
HERE ARE THE SYMPTOMS OF H3N2 VIRUS:
- Cough
- Runny nose or congested nose
- Sore throat, headaches
- Body aches
- Fever
- Chills,
- Fatigue
- Diarrhoea
- Vomiting
- Breathlessness
How H3N2 influenza differs from COVID-19?
H3N2 influenza and COVID-19 are caused by highly infectious viruses. These viruses can spread through droplets and can also mutate significantly. Although these respiratory diseases originate from a different family of viruses, they are contagious and are easily transmitted. COVID is caused due to SARs-CoV-2 virus. Meanwhile, the H3N2 virus is an influenza A subtype occurring in humans. The latter has reportedly seen many cases of hospitalizations rather than other virus variants.
What makes H3N2 influenza stand out from the rest?
The reported cases of the influenza virus are spotted under upper respiratory tract symptoms. They are inclusive of headache, runny nose, sore throat, whooping cough etc. Although, the noteworthy symptom is a persistent cough that doesn’t seem to fade away. As per Indian Medical Association (IMA) seasonal fever usually persists from five to seven days, however, in certain cases, the cough can last for approximately three weeks.
How to identify whether it is COVID or flu?
It goes without saying that getting a health check-up is the one and only method to find out if you have COVID or the flu. Try opting for Rapid Antigen test as its results are quickly delivered or an RT-PCR Test , which gives quite accurate results but can take some time to deliver results. COVID and FLU tests usually need a respiratory sample, for instance, a nasal swab to track the flu presence in the body.
Dos and Don’ts
- Wash your hands frequently. Use soap and water to thoroughly clean your hands, or an alcohol-based hand sanitiser if neither is available.
- Cover your coughs and sneezes. Sneeze or cough into a tissue or your elbow. Wash your hands quickly.
- Avoid touching your face excessively, including your eyes, nose, and mouth.
- Keep commonly touched surfaces clean to avoid taking up the virus and transmitting it to your body.
- Avoid crowds. Avoid congested regions whenever feasible. Maintain your distance from sick people if you are at high risk of flu complications due to your age, health, or both.
- Wear a mask and carry a hand sanitiser with you.
- Do not share personal items like clothes, towels, or water bottles.
- Stay hydrated and eat a healthy diet to boost your immune system.
- Get regular check-up or consult your doctor, to avoid severe disease and its complications.

Benefits of Timely Testing During Fever and Infection
Fever is the body’s natural response to infections. It signals that the immune system is actively fighting against the harmful pathogens such as bacteria, viruses, or fungi. While a mild fever often resolves on its own, a persistent or high-grade fever can indicate an underlying infection that requires medical attention. In such cases, timely diagnostic testing plays a critical role in identifying the cause of the illness and guiding appropriate treatment. Ignoring a prolonged fever or delaying tests can lead to complications and poor health outcomes.
Accurate Diagnosis of the Underlying Condition
One of the primary benefits of timely testing during fever and infection is the ability to diagnose the root cause accurately. A fever can be a symptom of a wide range of conditions, including viral infections such as dengue or influenza, as well as bacterial infections like typhoid or urinary tract infections (UTIs). Diagnostic tests such as complete blood count (CBC), fever panel, blood cultures, or specific tests like malaria or dengue antigen tests help identify the specific organism responsible for the illness. An accurate diagnosis ensures that the patient receives the most effective treatment and avoids unnecessary medications.
Early Detection Prevents Complications
Some infections progress faster than we realize. When fever strikes, don’t just guess the cause - test it.
Early testing can help detect potentially dangerous infections before they worsen. For instance, infections like dengue or leptospirosis can rapidly progress if not diagnosed and treated in time. A delayed diagnosis may lead to severe complications such as dehydration, organ failure, or even death.
Reduces the Risk of Transmission
Infections like influenza, and tuberculosis are highly contagious. Timely testing during the onset of symptoms, especially fever, helps in identifying such infections early and isolating the patient to prevent further spread. This is particularly important in households with children, elderly family members, or individuals with weakened immune systems. Early detection through testing also enables health authorities to take preventive measures in the community.
Helps Avoid Self-Medication and Misdiagnosis
Many individuals tend to self-medicate when they develop a fever, assuming it is a minor viral infection. However, self-medication can be harmful, especially if the actual cause is a serious bacterial or parasitic infection. By undergoing timely tests, individuals can avoid misdiagnosis and receive appropriate medical advice. This also prevents the misuse of antibiotics, which is a major cause of antibiotic resistance.
Supports Monitoring and Better Treatment Planning
Timely testing during fever or infection helps doctors monitor the illness's progression and adjust treatment accordingly. For example, repeated blood tests may be necessary to assess whether a patient's white blood cell count is returning to normal or if the infection is worsening. This data helps healthcare professionals make informed decisions, improve treatment outcomes, and avoid unnecessary hospitalizations.
Peace of Mind for the Patient
Knowing the exact cause of fever through timely testing can also bring peace of mind to patients and their families. It reduces anxiety, eliminates guesswork, and provides a clear path to recovery. Rather than waiting in uncertainty, patients can take swift action based on reliable test results.
Timely testing during fever and infection is not just a diagnostic step, it is a crucial component of effective healthcare. It helps in identifying the cause, preventing complications, limiting disease transmission, and supporting accurate treatment. Investing in early testing is a proactive approach to health that ensures quicker recovery, reduces healthcare costs in the long run, and ultimately saves lives.

Viral Infection
When Should You Get Tested for a Bacterial or Viral Infection
The medical testing for bacterial or viral infections is crucial for effective treatment and recovery. Both types of infections can present similar symptoms, making it challenging to distinguish between them. However, appropriate testing and diagnosis ensure that individuals receive the correct treatment, prevent complications, and promote faster healing.
Recognizing Symptoms of Infections
Viral infections, such as the common cold or influenza, often present with symptoms like runny nose, cough, sore throat, and low-grade fever. These symptoms typically develop gradually and improve within a week to ten days. Bacterial infections, on the other hand, may cause more severe symptoms, including high fever, significant fatigue, and localized pain, depending on the affected area. For instance, bacterial infections like strep throat can lead to a sudden, severe sore throat without typical cold symptoms like coughing.
When to Seek Medical Testing
It is essential to consult a healthcare provider for testing in the following situations:
- Persistent or Worsening Symptoms: If symptoms persist beyond 10 to 14 days or worsen instead of improving, it may indicate a bacterial infection requiring medical attention.
- High Fever: Experiencing a fever higher than typically observed with a viral infection suggests the need for medical evaluation.
- Severe or Unusual Symptoms: Symptoms such as difficulty breathing, chest pain, sudden dizziness, or severe headaches warrant immediate medical attention.
- Underlying Health Conditions: Individuals with chronic illnesses, weakened immune systems, or those undergoing treatments that suppress immunity should seek prompt medical advice when experiencing infection symptoms.
- Infants and Young Children: Young children, especially those under three months old with a fever, should be evaluated by a healthcare provider to rule out serious infections.
Diagnostic Methods
Healthcare providers develop various tests to differentiate between the bacterial and viral infections:
- Physical Examination: This symptoms assess and medical history and also identify potential infection sources.
- Laboratory Tests: The Blood tests, urine tests, and throat swabs, imaging studies that help find out the nature of the infection.
- Complete Blood Count (CBC): It also evaluate the white blood cell counts that indicate the occurrence of an infection and help differentiate between bacterial and viral causes.
The Importance of Accurate Diagnosis
The importance of an accurate diagnosis are suitable treatment, preventing complications by early identification and treatment of bacterial infections, and reducing transmission by taking measures to decrease the spread of infections. For the more common causes of pneumonia in children, it is even more important to recognize which of these diseases are caused by viral and which by bacterial infection because, in the case of the latter, the treatment will usually be with antibiotics. This is important in preventing complications, as failure to diagnose and treat meningitis, for example, can lead to life-threatening illnesses. Good diagnosis enables the execution of appropriate measures to stop the spread of infectious diseases.
Conclusion
It can be concluded that how long and how serious the symptoms last in order to decide within that window when it is suitable to consult with a healthcare professional in order to run some tests for a bacterial or viral infection. Doctor consultation ensures that the diagnosis or the treatment offered will promote better health outcomes and decrease the risk of developing further complications. Always consider your health as a priority when in doubt of your illness, and be sure to seek the advice of a professional.

How to Differentiate Between Viral and Bacterial Fever
Fever can definitely be a common condition that affects people irrespective of age. It is most times a suggestion of the body being in a fight alongside an infection. However, it is very an important to recognize if a person has a viral fever or a bacterial fever to give the proper treatment. Viral fever is caused by the likes of flu or the common cold virus infection whereas, bacterial fevers are seen in infections like pneumonia and strep throat. There are also other distinctions regarding causes, symptoms, and treatment for both types that are being discussed. It also assists not only to speed up recovery but also in avoiding preventable use of drugs, especially antibiotics that do not act against any viral infection. When fever persists for several days and accompanies severe about symptoms, it is the time to see a doctor for diagnostic ascertainment and treatment.
What is Viral Fever
Viral fever happens when viruses infect the human body and compromise the immune system. It spreads quite easily through contact with an infected person, droplets in the air, or contact with infected surfaces. Common viral infections would include flu, common cold and dengue. Usually, the symptoms start mild, continuing with moderate fever, looking tired, body pains, runny nose, cough and sore throat. Some people probably will also develop headaches, bloodshot eyes or even diarrhea. Generally, a viral fever lasts for three to seven days and slowly goes away with bed rest, fluids, and some home remedies. Antibiotics are useless because they have no effect on viruses. Recovery should best happen with good rest and lots of fluids and medication for fever and aches. With awareness, the body will throw off the infection all by itself, and will become better in no time at all. Viral fever happens due to viruses infecting the body and making the immune system weak. It spreads quite easily by touching infected persons, by air droplets or by contact with infected surfaces. Common viral infections would be flu, common cold and dengue. Signs and symptoms usually start with mild moderate fever, fatigue, body pain, runny nose, cough and sore throat. Other persons may develop headaches or bloodshot eyes or even diarrhea. A viral fever usually subsides within three to seven days, while bed rest, adequate hydration and some home remedies are helpful too. Since antibiotics do not affect viruses, they do not require it. Good rest, lots of water and fever and pain medications, if needed, will bring about the best success in recovery. When properly cared for, the body will rid itself of the infection, and soon one feels better.
What is Bacterial Fever
A bacterial fever that takes place when certain, harmful bacteria enter the body either through wounds, impure food, or respiratory droplets. Pneumonia, urinary tract infections (UTIs), and typhoid are other types of infections that may follow. Symptoms of bacterial fever include high fever, chills, nausea, and vomiting. Viral fevers and bacterial infections are mostly treated with antibiotics upon the recommendation of a doctor. If left untreated, these infections may cause serious health problems. In order to determine if fever is of viral or bacterial origin, tests may include blood tests, throat swabs, or urine tests, and the doctor usually prescribes them. Taking the antibiotics without proper diagnosis is not an important thing to do since giving antibiotics without reason may lead to severe consequences. The best way to quickly see the doctor in case of not feeling well is to check out some diseases.
Conclusion
It can be concluded that differentiation between viral and bacterial fever, therefore, is necessary to achieve effective treatment. Whereas viral fever generally goes away on its own with proper care, bacterial fever requires antibiotics. Additionally, undergoing a fever screening panel test can help in identifying the underlying cause, ensuring appropriate treatment. A medical expert should be contacted if the fever extends over three days or if symptoms seem severe. An accurate or precise diagnosis and timely treatment can really prevent complications and lead to a faster recovery.
