Overview

This is a disease that is transmitted from mosquitoes to humans and affects many people in the world. Found in densely populated countries and continents, like Africa, Asia and the tropics of the Americas, this has severe symptoms. This viral disease is caused by the Chikungunya virus of the Togaviridae. First identified in the United Republic of Tanzania in 1952 and subsequently in other countries like Africa and Asia. Since 2004 the outbreak of CHIKV virus has become more widespread and caused partly due to the viral adaptations allowing the virus to be spread more easily by Aedes albopictus mosquitoes. The transmission has been noted to persist in countries where there is a large population, but interestingly, the transmission has been interrupted on islands where a high proportion of the population is infected and then immune.

Symptoms

The onset of the disease is usually in 4-8 days and after a bite of an infected mosquitoes, it is characterized by an abrupt onset of fever and then joint pain. This joint pain is severed and lasts for a few days but may prolong for months maybe even years. Other signs are joint swelling, muscle pains, headache, nausea, fatigue and rash. These symptoms also overlap with those of dengue and Zika virus and can be misdiagnosed. Most people fully recover from the infection and experience only mild and sometimes the infection even goes unrecognized. However, there have been cases of eye, heart, and neurological complications. The elderly and newborns are more susceptible to the infection and if they have any underlying conditions then they are likely to become severely ill increasing the risk of death.

Diagnosis and treatment

The diagnosis and treatment of the virus may be done by blood sampling and other tests like reverse transcriptase–polymerase chain reaction (RT–PCR). Other tests detect the activity of the antibodies. These can be detected in the first week after illness onset and can be detected for about 2 months. Many clinical measures can be taken to address fever and joint pain. But there is no specific anti-viral drug treatment for the virus.

Preventing Chikungunya

As this disease is caused by the bite of a mosquito, you must reduce the opportunities to let the mosquito breed. Mosquitoes bite during the day and night, and for people who live in risk areas like southeast Asia, Africa and tropical regions of America, many outbreaks happen each year. The best way to prevent it is to protect yourself from the mosquito's bite. You also must get vaccinated before travelling to any of these regions. Use insect repellent, and wear long-sleeved shirts and pants. You can also treat your clothes and gear with permethrin. As we all know, they tend to breed in humid places and places where they have access to water, so try to close the rooms that are air-conditioned with screens and windows. Use nets and mosquito repellents if you are sleeping outside. There are many different types of mosquito repellents like paper, liquid etc, and they are quite effective. If your job needs, you to be stationary for long hours or frequently go outside you must take the necessary precautions.

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.

Why Monsoon Raises Infection Risk in Children

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.

Common Mistakes Of Infections In Children

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.

Tips Parents Should Follow During the Monsoon

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.

Bryan Johnson's Autoimmune Gastritis: US Doctor Explains the Hidden Signs of Autoimmune Disease

Updated Jul 9, 2026 | 09:53 PM IST

Summary​According to the Centers for Disease Control and Prevention (CDC), autoimmune diseases occur when the immune system mistakenly attacks the body's own healthy cells and tissues, triggering inflammation and damage to organs or other body systems.

Billionaire entrepreneur Bryan Johnson, known for meticulously tracking his health and pursuing longevity, recently revealed that he has been diagnosed with Autoimmune Gastritis, an incurable autoimmune condition in which the body's immune system attacks the stomach lining.

Describing the disease on social media platform X, Johnson said: "My stomach is eating itself." He also noted that despite undergoing extensive medical evaluations over the years, the condition went undetected because autoimmune diseases often develop quietly, with symptoms that can easily be mistaken for everyday health issues such as fatigue or digestive discomfort.

According to the Centers for Disease Control and Prevention (CDC), autoimmune diseases occur when the immune system mistakenly attacks the body's own healthy cells and tissues, triggering inflammation and damage to organs or other body systems.

The burden of these conditions is significant. In May 2025, researchers from the Mayo Clinic and collaborating institutions estimated that nearly 15 million Americans are living with one or more of 105 recognized autoimmune diseases.

Symptoms Can Be Easy to Miss

Because autoimmune diseases often begin with vague, non-specific symptoms, they can remain undiagnosed for months—or even years.

Dr. Cory Rice, a US-based Functional Medicine physician, said these warning signs frequently go unnoticed until the disease has progressed.

"First and foremost, symptoms of autoimmune disease can come and go, and be on and off, or they can be more persistent in nature," he told Newsweek.

The Hidden Signs You Shouldn't Ignore

While symptoms vary depending on the various autoimmune conditions, several early warning signs are shared across many autoimmune diseases.

According to Dr. Rice, common symptoms include:

  • Fatigue
  • Low-grade fever
  • Joint pain
  • Unexplained rashes or hives
  • Dry eyes and dry mouth
  • Numbness or tingling in the hands or feet
  • Mouth ulcers
  • Increased sensitivity to cold temperatures

He said when people suffer from fatigue, "it is usually both profound and debilitating."

Dr. Rice explained that many people try to manage this overwhelming exhaustion by relying on caffeine and other stimulants, taking thyroid medications or hormone treatments, or opting for therapies such as intravenous infusions and vitamin B12 injections.

However, when an underlying autoimmune disease is responsible, these approaches often fail to provide lasting relief.

Why Autoimmune Diseases Are Often Diagnosed Late

One of the biggest challenges in diagnosing autoimmune diseases is that their symptoms overlap with those of many other medical conditions.

Johnson also said that "2-5 per cent of people have this (autoimmune disease). Likely more, because it hides".

Symptoms may also appear intermittently before becoming more persistent.

"It all depends on the disease process in play and the severity or progression of the disease itself in a particular person as to whether symptoms are more constant or intermittent," Rice said.

He added that many primary care physicians are not routinely trained to identify autoimmune diseases in their early stages. As a result, patients are frequently referred to specialists, including rheumatologists, only after symptoms have become more pronounced.

"Unfortunately, by this point, the autoimmune disease may already be far along in whichever parts of the body are impacted," he said.

Dr. Rice emphasized that recognizing symptoms early and obtaining a timely diagnosis can help slow disease progression and improve long-term outcomes.

As Cyclospora Cases Surge In The US, Expert Explains Why India's Monsoon Raises Risk Of The Parasitic Infection

Updated Jul 9, 2026 | 03:00 PM IST

SummaryJust like the United States grappling with the worst outbreaks in the history of cyclospora, India also faces a certain degree of risk of the parasitic infection, especially in monsoon.

The United States is currently experiencing one of its worst Cyclospora outbreaks in recent years, with health officials still unable to determine the source of the infections.

According to the latest data, the outbreak has spread across at least 18 states. Michigan has reported at least 1000 cases, emerging as the hardest-hit state. With around 40 hospitalisations, no deaths have been reported so far.

Cyclospora Outbreak In The US

The outbreak is being investigated by the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Food and Drug Administration (FDA), and state health departments. Investigators have not yet identified a single contaminated food source.

Several other states have also reported rising case counts. New York City has confirmed hundreds of infections since May. Health officials believe the actual number of infections is likely higher because Cyclospora is not routinely tested for in people with diarrhea. Symptoms usually begin about one week after exposure and can last weeks if untreated.

About Cyclospora

A Cyclospora infection can be mild or severe and may last for weeks or even months. It is typically treated with antibiotics. People with weakened immune systems, such as those with HIV/AIDS or cancer, are at greater risk of severe disease.

Cyclospora infection commonly causes:

  • Prolonged watery diarrhea
  • Severe abdominal cramps
  • Fatigue
  • Loss of appetite
  • Nausea
  • Weight loss
  • Bloating

Health authorities in the US continue to advise people to wash fresh produce thoroughly, maintain good hand hygiene, and seek medical care if they develop prolonged watery diarrhea, especially if symptoms persist for several days.

Does India’s Monsoon Raise Risk Of Cyclospora?

While there is no indication of a similar outbreak in India, infectious disease experts say the country's monsoon season creates conditions that can facilitate the spread of intestinal parasites if food and drinking water become contaminated.

HealthandMe spoke to Dr. Devashish Desai, Consultant, Infectious Diseases at Ruby Hall Clinic, if India, too, faces a possibility of a parasitic infection like cyclospora, especially in monsoon season.

Dr Desai said, “The answer is yes. India's monsoon creates conditions that favour the spread of several water and food-borne infections, including Cyclospora. Heavy rainfall can contaminate drinking water sources and fresh fruits and vegetables with sewage or infected soil. Consuming raw salads, unwashed herbs, or untreated water significantly increases the risk of infection.”

Unlike bacteria, cyclospora parasites require time in the environment before they become infectious, meaning direct person-to-person transmission is uncommon. Instead, contaminated food and water remain the primary sources of infection. This makes maintaining hygiene from farms to kitchens essential for prevention.

The expert added, “Although Cyclospora outbreaks are not commonly reported in India, the environmental conditions during the rainy season make vigilance essential. Strong food safety practices, clean water, and good personal hygiene remain the most effective defences against this preventable parasitic infection.”

Although India has not reported a similar outbreak, experts say the current situation in the US is a stark reminder that food safety and sanitation become even more critical during the monsoon.
