Scrub Typhus is a transmitting virus that has spread rapidly in Tamil Nadu. In response, the Directorate of Public Health has released essential guidelines to control its spread. Understanding this disease is an important step in safeguarding yourself and your loved ones. Therefore, in this blog, we’ll explore what Scrub Typhus is, its causes, symptoms, and the treatments available.
Scrub Typhus
Scrub Typhus is a bacterial infection caused by Orientia tsutsugamushi. This disease is transmitted through the bites of infected larval mites, also known as "chiggers," which thrive in environments with dense vegetation. People who spend time in such environments are more susceptible to the infection.
Causes of Scrub Typhus
The changing climate in Tamil Nadu provides a chance for the mites that spread Scrub Typhus (chiggers), to thrive.
Symptoms of Scrub Typhus
The common symptoms of Scrub Typhus are:
· Fever
· Headache
· Fatigue
· Rashes
In some cases, the untreated Scrub Typhus leads to
· Pneumonitis
· Meningitis
· Organ failure
Scrub Typhus Diagnosis
Early diagnosis and treatment are essential to prevent complications from Scrub Typhus. The infection can be identified through diagnostic tests such as the ELISA blood test, which detects specific antibodies, and molecular tests like PCR, which confirm the presence of the bacteria.
Treatment Options for Scrub Typhus
Scrub Typhus is typically treated with antibiotics such as azithromycin and doxycycline, which are effective in combating the infection. In severe cases, hospitalization may be necessary to provide advanced medical care and manage complications.
Who Is at Risk?
People who frequently work or live in grassy or bushy areas such as Farmers and outdoor workers who spend extended time in green and dense regions are more susceptible to Scrub Typhus. In addition, people with weakened immune systems and pregnant women are vulnerable to this illness.
Preventive Precautions
· Wear long-sleeved clothing and full-length pants for protection.
· Apply insect repellents to keep mites away.
· Stay away from areas with dense grass or bushes where mites thrive.
· Practice good personal hygiene to reduce the risk of infection.
Conclusion
Staying informed and taking preventive measures are key to reducing the risk of Scrub Typhus. In 2024, Tamil Nadu reported approximately 5,000 cases, highlighting the importance of awareness and early intervention. Anyone experiencing a fever lasting five or more days, with or without an eschar, should seek medical advice immediately, as it may indicate Scrub Typhus. Early diagnosis and treatment are crucial for effective recovery. Stay vigilant, take precautions, and prioritize your health.
As India grapples with a recent surge in Human Metapneumovirus (HMPV) cases, many are drawing parallels to the COVID-19 pandemic due to similar respiratory symptoms. But what exactly is HMPV, and should we be concerned about it? This comprehensive blog will explain everything you need to know about this respiratory virus, from its severity and transmission to symptoms, diagnosis, and prevention strategies.
What is Human Metapneumovirus (HMPV)?
Human metapneumovirus (HMPV) is a respiratory pathogen belonging to the Pneumoviridae family and the Metapneumovirus genus. First discovered in 2001, this single-stranded negative-sense RNA virus has established itself as a significant cause of respiratory infections worldwide. While it may sound complex, HMPV is a common respiratory infection that typically appears during the winter and early spring months.
The virus is prevalent in human populations, with most people experiencing their first HMPV infection during early childhood. While the body develops some immunity after initial exposure, the virus can still cause repeat infections throughout a person's life, though these tend to be milder than the first encounter.
Human Metapneumovirus Symptoms
Most HMPV symptoms are mild and resolve within 2-5 days. These include:
- Coughing
- Nasal congestion
- Runny nose
- Fever
- Sore throat
- Nausea
- Vomiting
- Diarrhoea
In severe cases, symptoms may include:
- Wheezing
- Asthma flare-ups
- Difficulty breathing
- Fatigue
- Bronchitis
- Ear Infection
- Pneumonia
- Severe bronchiolitis (more common in children)
HMPV is responsible for about 10% to 12% of
respiratory illnesses in children. While most cases are mild, up to 16% can
lead to serious complications, such as pneumonia or lower respiratory tract infections. Babies under 1 may have feeding difficulties. If symptoms last
beyond two weeks or worsen, seek medical attention immediately.
Who is at Risk?
HMPV poses a higher risk to:
- Young children: May develop bronchiolitis or pneumonia.
- Elderly: Especially those 65+ or with asthma, COPD, or chronic illnesses.
- Pregnant women: Can experience respiratory issues affecting both mother and baby.
- Immunocompromised individuals: At risk of severe symptoms due to conditions or treatments like chemotherapy.
- Individuals who have asthma or COPD.
Human Metapneumovirus (HMPV) vs. COVID-19
HMPV and COVID-19 are contagious respiratory illnesses with similar symptoms, including runny nose, cough, fever, congestion, sore throat, and shortness of breath. Both can cause severe cases requiring hospitalization. However, unlike COVID-19, HMPV lacks antiviral treatments or vaccines and is seasonal, peaking in winter and spring. Studies show HMPV cases tripled in some countries post-pandemic, as eased COVID-19 measures increased exposure to respiratory illnesses.
How is Human Metapneumovirus Spread?
Human metapneumovirus (HMPV) is caused by a virus related to RSV, measles, and mumps, which infects the respiratory system. It spreads primarily through
Close contact with an infected person: Coughing, sneezing, shaking hands, hugging, or kissing.
Contaminated surfaces: Touching objects like toys, phones, or door handles with the virus.
Human Metapneumovirus Diagnosis
Healthcare providers typically diagnose HMPV based on your symptoms and medical history. To confirm the infection, they may take a sample from your nose or throat using a soft-tipped swab, which is then tested in a lab for viruses and other infections. Testing for HMPV is generally reserved for those with severe symptoms. In some cases, a bronchoscopy or chest X-ray may be performed to examine the airways and check for lung changes.
Treatment of Human Metapneumovirus
There is no specific cure for HMPV, but symptoms can be managed with supportive care. Mild cases often improve on their own. To ease symptoms, you can:
- Take over-the-counter pain relievers for fever and pain.
- Use decongestants or corticosteroid sprays for nasal congestion.
- Use an inhaler for breathing difficulties like wheezing.
Severe cases may require hospitalization for oxygen therapy, IV fluids, or corticosteroids to reduce inflammation. Antibiotics are not effective unless a secondary bacterial infection occurs.
Prevention of Human Metapneumovirus
While there’s no vaccine for HMPV, you can reduce the risk of infection by:
- Washing your hands regularly with soap and water for at least 20 seconds.
- Avoiding close contact with sick individuals.
- Covering your mouth and nose when coughing or sneezing, preferably into your elbow.
- Using alcohol-based sanitizers or wipes after sneezing or touching high-contact surfaces.
- Try to stay at home when you experience any symptoms.
People with chronic lung conditions like COPD or asthma should take extra precautions and stay up to date on vaccinations to protect against respiratory infections.
HMPV Virus in India
Human Metapneumovirus (HMPV) is a globally circulating respiratory virus, including in India. While India recently confirmed two cases at a Bengaluru hospital, the Union Health Ministry emphasized there has been no unusual surge in cases. Experts clarified that HMPV is not new, having been identified in 2001 and likely existing since the 1950s. It primarily causes mild respiratory infections, and most children develop immunity by age 10.
Current data from the Indian Council for Medical Research (ICMR) and the Integrated Disease Surveillance Programme (IDSP) shows no significant rise in Influenza-Like Illness (ILI) or Severe Acute Respiratory Illness (SARI). Hospitals are well-prepared, and health systems remain vigilant. Citizens are advised to take standard precautions, such as wearing masks, washing hands, and consulting a doctor if severe symptoms occur.

The liver plays an essential role in our body. It helps in the detoxification process by filtering out harmful substances from the blood and producing bile to aid in digestion. When the liver is damaged or exposed to toxins, it loses its ability to function normally. In recent times, non-alcoholic fatty liver disease (NAFLD) has emerged as a major health issue, affecting millions of people worldwide. Understanding the risk factors of NAFLD is crucial for effective management. In this blog, you will learn about these risks and find ways to protect your liver health.
Non-Alcoholic Fatty Liver Disease (NAFLD)
Non-alcoholic fatty Liver Disease (NAFLD) is a condition identified by the buildup of fat in the liver of individuals who consume minimal or no alcohol. If NAFLD is not treated properly for a long period of time it leads to serious liver conditions, such as non-alcoholic steatohepatitis (NASH) and cirrhosis, liver cancer, or liver failure.
Causes of NAFLD
The causes of non alcoholic fatty liver disease is not clear, but the researchers believe the following factors may contribute to its development:
- Genetics
- Overweight or obesity
- Insulin resistance
- High levels of triglycerides in the blood
- Metabolic syndrome
NAFLD Signs and Symptoms
Generally, non alcoholic fatty liver disease is a silent disease with no indications. However, when the disease progresses some individuals may experience symptoms such as:
- Fatigue
- Weakness
- Abdominal discomfort
- Jaundice
Who is at Risk?
The non-alcoholic fatty liver disease is common in people who are overweight or obese, have type 2 diabetes, or have high cholesterol. It is also more prevalent in older adults and those with a sedentary lifestyle. Additionally, individuals with a family history of liver disease may be at an increased risk for developing NAFLD.
How to Prevent NAFLD
There are several ways to prevent NAFLD and promote liver health. The following strategies can help reduce the risk of developing it:
- Eat healthy: Include foods that support liver health, such as fruits, vegetables, whole grains, and lean proteins
- Exercise daily: Aim for at least 25 minutes of exercise a day.
- Avoid processed foods: Processed foods are high in unhealthy fats, sugars, and additives that can contribute to liver damage.
- Manage chronic conditions such as diabetes and high cholesterol: These conditions can contribute to liver damage, so it is important to work with your healthcare provider to keep them under control.
How is NAFLD Diagnosed?
NAFLD has no symptoms. Generally, it is identified after the blood test results that higher-than-normal levels of liver enzymes.
Once NAFLD is suspected, the doctor goes for physical examinations like insulin resistance, and cirrhosis. In addition, the healthcare professional may recommend for
- Ultrasound to understand the fat in the liver
- Transient elastography to measure the liver stiffness
- Liver biopsy for accuracy
Treatment Options
Treatment for non-alcoholic fatty liver disease has no specific medications or specific treatments. Studies are currently being conducted to determine whether a specific diabetes medication or Vitamin E can be beneficial; however, further research is needed.
In addition, losing weight is commonly suggested for managing this condition. So, for some individuals weight loss surgery is recommended.
When to Consult a Doctor?
- It is important to consult a doctor if you are experiencing symptoms such as fatigue, abdominal pain, or yellowing of the skin and eyes.
- Regular check-ups and monitoring of liver function tests are recommended for those at risk of NAFLD.
In conclusion, NAFLD is a serious but manageable condition with a significant impact on liver health. By altering the lifestyle and making healthier choices, individuals with NAFLD can improve their liver function and reduce the risk of developing more severe liver diseases such as cirrhosis or liver cancer. If you are at risk of developing inflammation or scarring in your liver, consult with your healthcare provider.

Dengue
The mosquito-borne tropical sickness caused by the dengue virus can be extremely painful and life-threatening, necessitating hospitalization. Symptoms usually last 2-7 days and include high fever, headache, nausea, vomiting, rash, muscle and joint aches. Most dengue patients recover in roughly a week. If you are experiencing vomiting, dizziness, or difficulty breathing, consult a doctor.
Malaria
Malaria, another mosquito-borne disease, is caused by Plasmodium parasites carried by infected Anopheles mosquitoes. It causes fever, chills, and flu-like symptoms, which can be severe if not treated promptly. Blood tests are used to diagnose malaria, and while it may be treated with antimalarial medications, certain strains become resistant.
Cholera
Cholera is a bacterial infection caused by Vibrio Cholerae that results in severe diarrhoea and dehydration. It spreads by contaminated water and food, which is more likely during the rainy season due to flooding and poor sanitation. If left untreated, cholera can kill a person within hours. Treatment consists of oral rehydration therapy and, in extreme situations, intravenous fluids.
Typhoid
Typhoid, caused by the Salmonella Typhi bacteria, is transmitted by contaminated food and drink. Symptoms include high fever, weakness, stomach ache, and loss of appetite. If not addressed, it can cause prevalent serious consequences. Typhoid is detected with blood, stool, or bone marrow testing and can be treated with antibiotics, though certain strains are becoming resistant.
Cold and Flu
The extreme temperature fluctuations that occur during the rainy season make the body susceptible to bacterial and viral attack, resulting in colds and flu. This is the most prevalent type of viral infection. To safeguard the body, one should eat highlyb nutritious foods to increase immunity. This allows the body to combat pathogens by generating antibodies that are resistant to the toxins that have been released.

In recent times, the term "flesh-eating" bacterial infection has captured headlines and sparked fear among many. Also known medically as necrotizing fasciitis, this rare but serious condition can indeed be alarming due to its rapid progression and potential for severe outcomes. However, understanding the facts about this condition is crucial to dispelling myths and ensuring informed awareness.
What is Necrotizing fasciitis?
Necrotizing fasciitis, also known as "flesh-eating bacteria" or "flesh-eating disease," is a rare yet serious infection that targets the skin and tissues beneath it. The term "necrotizing" refers to the infection's ability to cause tissue death, while "fasciitis" indicates inflammation of the fascia, the connective tissue beneath the skin.
This condition falls under the broader category of necrotizing soft tissue infections (NSTIs), which are life-threatening infections impacting skin, muscles, and other soft tissues. NSTIs are characterized by their rapid and aggressive spread, causing localized tissue death and potentially fatal outcomes if not effectively treated.
The effectiveness of necrotizing fasciitis lies in its efficiency in spreading and the extensive tissue damage it causes at the infection site. Immediate medical intervention is crucial for survival and minimizing long-term complications.
Necrotizing fasciitis Types
- Type I, also called as polymicrobial occurs when the infection is caused by a combination of of aerobic and anaerobic bacteria, typically more than one.
- Monomicrobial, also known as Type II, is commonly caused by either group A streptococcus or Staphylococcus aureus bacteria.
Causes of Necrotizing Fasciitis
The infection is mostly caused by bacteria such as Group A Streptococcus (Streptococcus pyogenes) or methicillin-resistant Staphylococcus aureus (MRSA). These bacteria can enter the body through breaks in the skin, such as cuts, surgical wounds, insect bites, or even minor injuries that may go unnoticed.
Symptoms and Diagnosis
Early detection of necrotizing fasciitis is critical for successful treatment. Symptoms may include:
- Severe pain in the affected area, often disproportionate to the injury.
- Swelling, redness, or warmth around a wound or injury.
- Fever, chills, fatigue, and nausea.
- Rapid progression of symptoms, with skin discoloration turning purplish or dark.
Diagnosis involves a thorough clinical examination, imaging studies (like CT scans or MRIs), and sometimes surgical exploration to assess the extent of tissue damage and confirm the presence of necrosis.
Prevention
While necrotizing fasciitis is rare, there are steps individuals can take to reduce their risk:
- Prompt Wound Care: Clean and cover wounds properly, especially if you have underlying health conditions.
- Maintain Good Hygiene: Wash hands regularly, especially before handling wounds or eating.
- Seek Medical Attention: If you notice signs of infection, such as increasing pain, redness, or swelling around a wound, seek medical advice immediately.
In the News: The recent outbreak of this bacterial infection in Japan has alarmed other countries, like Japan, India, etc. However, the medical experts in India have said that they did not anticipate the possibility of the disease outbreak in India in the near future. Conclusion Understanding necrotizing fasciitis involves dispelling misconceptions and recognizing the importance of early detection and treatment. While it is a serious condition that demands knowledge and awareness that help individuals to recognize symptoms early, get timely medical care, and improve their chances of a successful recovery.
