One of the commonest causes of illness, a sore throat often clears up on its own, but knowing what's causing it is important to treat it properly. Viral, bacterial, or caused by allergic elements - these kinds of sore throats have different characteristics that need different responses.
Sore throats have several origins, including infection and environmental factors. Some common causes include:
Viral infections: Viruses cause 90% of sore throat cases. Sore throats may result due to flu or common cold as well as those from chickenpox and measles that can all cause irritation.
Bacterial Infections: Streptococcus bacteria, the most common cause of strep throat, is the most common bacterial source. Strep throat is contagious and can lead to complications if untreated.
Allergies: Pollen, pet dander, and mold can trigger throat irritation, often accompanied by postnasal drip, sneezing, and watery eyes.
Environmental Factors: Dry air, pollution, and smoke can dry out or irritate the throat, creating a scratchy sensation.
Other Causes: GERD, vocal strain, even tumors may be responsible for chronic sore throats.
Determining your cause of sore throat requires analysis of symptoms that accompany it, how long the sore throat lasts, and how bad the sore throat is.
The viruses that cause a sore throat are usually similar to a cold in their symptoms and tend to be milder than bacterial infections.
- Red, swollen throat without white patches
- Persistent cough
- Runny nose and nasal congestion
- Fever, usually mild
Duration: Viral infections last for 7–10 days without antibiotics.
Treatment: Home remedies, such as warm fluids, saltwater gargling, and over-the-counter pain relievers can help alleviate it.

Bacterial sore throats, mainly strep throat, are more severe and require prompt medical attention to prevent complications.
- Red and swollen tonsils with white patches or streaks of pus
- High fever
- Absence of a cough
- Nausea, vomiting, or stomach pain (especially in children)
- Small red spots on the roof of the mouth
Diagnosis: Rapid strep tests or throat cultures confirm the presence of bacteria.
Treatment: Antibiotics are necessary to eliminate the infection. Without treatment, complications like rheumatic fever or abscesses can develop.
Throat irritation is caused by postnasal drip. Allergies create a buildup and drip of mucus down the back of the throat.
- Irritation of the throat and ears
- Runny eyes, sneezing, and nasal congestion
- These symptoms are usually relieved by antihistamines or removal from the source of the allergen
Duration: Allergic sore throats are sustained for as long as the allergens are exposed.
A sore throat should be taken to a doctor if:
- The condition lasts more than a week.
- There is shortness of breath or swallowing becomes painful.
- Swelling is too pronounced or the pain in the throat is extreme.
- High fever, rash, or joint pain occur along with the sore throat.
- A child shows signs of dehydration or refuses fluids due to throat pain.
Early diagnosis can prevent complications and speed recovery.
Viral infections and allergies often respond well to non-invasive treatments:
Let your body rest sufficiently. Humidifying dry air will help keep the throat moist, especially when winter is on its way.
Bacterial infections require antibiotics such as penicillin or amoxicillin. Finish the treatment completely to avoid reoccurrence or resistance.
Prevention is better than cure, and simple lifestyle changes can reduce your risk:
Understanding the cause of your sore throat—whether viral, bacterial, or allergic—is key to effective treatment and recovery. While many sore throats resolve on their own, seeking timely medical advice for persistent or severe symptoms can prevent complications. Prioritize self-care, and don’t hesitate to consult a doctor when needed. Remember, your throat’s health is a vital part of your overall well-being.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.
The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.
The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:
Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.
The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.
Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.
The study found evidence of:
Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.
This abnormal pupil function was also associated with:
The study also identified impaired coordination between the two eyes.
Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.
Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.
Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.
The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.
Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.
"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.
He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.

Cardiovascular-kidney-metabolic (CKM) syndrome is emerging as a major public health threat, according to new guidelines from the American Heart Association (AHA), which identify obesity as a key driver of the condition's development and progression.
The guidelines, jointly issued by the AHA and the American College of Cardiology (ACC), reframe excess weight as more than a number on the scale, describing it as a significant health risk closely linked to diabetes, chronic kidney disease and cardiovascular disease.
According to the AHA, nearly 9 in 10 adults in the United States have at least one condition associated with CKM syndrome. These include high blood pressure, abnormal cholesterol and other lipid disorders, high blood sugar, reduced kidney function and excess body weight.
With obesity rates continuing to rise, the guideline urges healthcare professionals to have prevention-focused conversations with patients about maintaining a healthy weight to reduce the risk of future heart, kidney and metabolic diseases.
“CKM syndrome is a real, rising public health threat,” said Chiadi E. Ndumele, an American Heart Association volunteer and chair of the writing committee for the new guideline.
“In terms of CKM health, weight is not just about a number on a scale — people with the same body weight can have very different health profiles. Rather, what’s most important is how fat tissue affects your metabolic health. This includes how your body manages blood sugar levels and how fat is used and stored,” Ndumele, who is also director of obesity and cardiometabolic research at Johns Hopkins University in Baltimore.

The updated guideline replaces the 2013 recommendations for managing overweight and obesity. CKM syndrome itself was first formally defined by the American Heart Association in 2023.
The guideline highlights several strategies to improve the prevention and treatment of CKM syndrome:

The monsoon brings welcome relief from the heat, but it also creates conditions that make infections spread more easily among children. Parents should understand that a few common household mistakes can increase the risk of illness in children during this time of year. So, parents must exercise caution and take utmost care of their children during those rainy days.
The arrival of the monsoon often means more time spent indoors for children, muddier surroundings, and increased exposure to germs. So, the main focus of parents is on protecting their children from rain and cold weather. However, parents must understand that certain everyday habits at home may unknowingly increase the risk of respiratory infections, stomach illnesses, and mosquito-borne diseases.
So, many children can get drenched during those heavy rains and remain in wet clothes or footwear for long periods after returning from school or outdoor activities. Damp socks and shoes can create an environment where germs and fungal infections thrive. Parents should ensure that children change into dry clothes and footwear as soon as possible. Moreover, stagnant water collected in flower pots, buckets, coolers, balconies, and outdoor containers can become breeding grounds for mosquitoes, raising the chances of dengue, malaria, and chikungunya in children.
Many families keep doors and windows closed throughout the day to prevent rainwater from entering the house. However, limited air circulation can lead to the growth of mold, dampness, and indoor allergens, which may trigger respiratory infections, coughing, wheezing, and allergies in children. Even having uncovered food, improperly stored leftovers, or contaminated water can increase the risk of stomach infections, diarrhea, vomiting, and food poisoning in children.
Parents should ensure that the child changes wet clothes, socks, and shoes immediately after returning home. Parents should empty and clean containers that can collect stagnant water from time to time. Use mosquito nets, screens, and child-safe mosquito repellents to prevent mosquito bites. Keep rooms well ventilated whenever the weather permits. The child should follow good hand and personal hygiene, eat freshly cooked food, and drink safe drinking water.
The parents should ensure to wash fruits and vegetables thoroughly before consumption. The child should eat a nutritious diet, sleep well, and stay hydrated to boost immunity and prevent any illness. Parents should seek immediate help if the child is having any symptoms, such as a cough or allergies, and follow the expert's guidelines. Parents should not give any medication to the child on their own without the doctor's knowledge. So, parents should stay alert during the monsoon and help the child stay healthy.
