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.

Micro-habits. What are they? Many claim that these micro-habits can, in fact transform your life. Every new year, we come up with goals and ambitions, while some changes could be long lasting ones, some are small, almost like mundane habits. These habits are not much demanding, but they can fit into your lives seamlessly and change your life, for good.

They do not bring instant transformation, but could help you stay healthier and in fact, live longer.

Here are some micro-habits that you too can adopt.

Movement

Ensure that movement is non-negotiable in your plan. There have been many studies that say that you no longer need 10,000 steps to achieve your fitness goal. In fact, 4,000 steps per day could help you stay fitter. Your fitness journey could start by ensuing that you ensure your body is under movement, whether it is step count, light stretching between meeting and long hour at desk or ditching that escalator or elevator for stairs.

Light Is A Must

Make sure you give expose yourself to enough light. Natural light is important for your body's circadian rhythm. This also supports better sleep, better mood and sharper focus.

Coffee, But Timely

Your body has cortisol that is naturally released in the morning. This hormone helps you to wake up. However, drinking coffee too early could interfere this rhythm, and you may find yourself crashing later in the day. Make sure you drink water and keep yourself hydrated.

Mindful Eating

Ensure that whenever you are having a meal, you are eating without distraction. This also helps you regulate your appetite and you become more aware of your hunger as your body is better able to give the fullness cues.

A Set Bedtime

Try to ensure consistency of when you sleep. If you sleep at the same time each night, it can help you strengthen your circadian rhythm. This consistency will also affect your mood, concentration and energy. The best part, this will help you avoid the social jetlag.

Breakaway From Alcohol

While there is no safe limit for alcohol consumption, if you are pressured about long-term leaving alcohol, try to give yourself a break. Try a 7-day no alcohol week, every now and then.

Listen To Your Cravings

If you are craving something salty, chances are your body lacks magnesium. There are many ways that craving tells you a lot about your body. Ensure that you run a full-body check to know what your body lacks. Fulfill these lacks with supplements, however, do make sure that these supplements are prescribed by your GP.

Read Labels

Mindful eating also comes when you start reading the labels of the food items you are buying. This way, you can know what you are putting in your gut system. Pay special attention for added sugars, processed food, and more.

Keep Your Gut-health Healthy

Go for pro-biotics, easy breakfasts like fermented rice, yogurt, khimchi and more. There are many studies that show the connection between gut health and rest of the body. If you keep your gut healthy, you will keep your body healthy too.

Timely Screening

A routine screening would help you stay one-step ahead of any disease. The key is that early diagnosis could cure the disease sooner without reducing the quality of life.

Hundreds of thousands of children are set to receive an additional vaccine under the NHS routine childhood immunisation programme. Health officials have confirmed it will be given alongside the existing MMR jab, which protects children in England against measles, mumps and rubella.

Chicken pox Vaccine Starts By NHS

The decision follows advice from the Joint Committee on Vaccination and Immunisation and will see the current MMR jab replaced with a combined MMRV vaccine. This single injection protects against measles, mumps, rubella and chickenpox. Studies estimate that chickenpox in childhood leads to around £24 million a year in lost earnings and productivity across the UK. Alongside reducing this impact, the rollout is expected to save the NHS about £15 million each year in treatment costs linked to the illness.

Dr Claire Fuller, National Medical Director for NHS England, said: “This marks a very positive step for children and families, offering protection against chickenpox for the first time and strengthening the range of routine vaccinations we already give to help shield children from serious diseases.

“From now on, the combined vaccine covering measles, mumps, rubella and chickenpox will be offered at children’s routine vaccination appointments. This will help keep children healthier, prevent illness caused by these highly infectious viruses, and support the NHS shift from treating sickness to preventing it, while keeping more children safe and in school.”

Recent figures show that around half of children will have chickenpox by the age of four, with nine in ten catching it before they turn ten. Children who develop chickenpox are usually advised to stay away from school until all spots have crusted over, which typically happens about five days after the rash appears.

With the new vaccine in place, fewer children are expected to miss time at nursery or school. This should also reduce the amount of work parents need to take off to look after them.

Who Can Get The Chickenpox Vaccine On The NHS?

Protection against chickenpox is being offered through a new combined vaccine known as MMRV, which replaces the existing MMR jab. The MMRV vaccine protects against measles, mumps, rubella and varicella, the virus that causes chickenpox.

• Children born after 1 January 2026 will automatically be offered two doses of the MMRV vaccine, given at 12 months and again at 18 months.
• A catch-up programme will also provide one or two doses for older children, depending on when they were born:
• children born on or after 1 January 2025 will be offered two doses, one at 12 months and one at 18 months
• children born between 1 July 2024 and 31 December 2024 will be offered two doses, one at 18 months and another at 3 years and 4 months
• children born between 1 September 2022 and 30 June 2024 will be offered one dose at 3 years and 4 months
• children born between 1 January 2020 and 31 August 2022 will be offered a single dose later in 2026
• GP practices will contact families directly to arrange vaccination appointments when they are due.

How Does The New Chickenpox Vaccination Work?

Specialists say adding the varicella vaccine to the NHS childhood immunisation schedule will significantly cut the number of people who get chickenpox, resulting in far fewer severe cases.

While the vaccine does not guarantee lifelong immunity, it greatly lowers the chances of catching chickenpox or developing a serious form of the illness. Serious side effects, including severe allergic reactions, are extremely uncommon.

The vaccine is a live vaccine, meaning it contains a weakened form of the chickenpox virus. Because of this, it is not recommended for people with weakened immune systems due to conditions such as HIV or treatments like chemotherapy.

The change brings the UK in line with countries that already include routine chickenpox vaccination, such as Germany, Canada, Australia and the United States.

In the past, there were concerns that vaccinating children against chickenpox could lead to an increase in shingles later in life, but a large long-term study from the US has since shown this is not the case.

The Joint Committee on Vaccination and Immunisation, which advises the government, recommended the introduction of the MMRV vaccine for all children in November 2023.

The government confirmed plans to roll out the MMRV vaccine in August 2025, after new figures showed that none of England’s main childhood vaccinations reached the 95 percent uptake target in 2024 to 2025.

According to the UK Health Security Agency, 91.9 percent of five-year-olds had received one dose of the MMR vaccine. This figure was unchanged from 2023 to 2024 and remains the lowest level recorded since 2010 to 2011.

Running to the bathroom with vomiting, diarrhea, or both is never fun. Yet “stomach bugs” are a common part of life, and norovirus is often behind these outbreaks.

Norovirus is a highly contagious virus that triggers symptoms like vomiting and diarrhea, and cases are climbing this winter. While it often makes headlines during cruise ship outbreaks, most infections occur on land, anyone can catch it.

“Originally called ‘winter vomiting disease,’ norovirus is one of the leading causes of vomiting and diarrhea in both children and adults,” explains Dr. Ava Anklesaria, a gastroenterologist at Columbia who treats multiple cases each year. “The virus is very stable in the environment, and only a tiny amount is needed to infect someone, which makes it easy to spread. Simple measures like washing your hands with soap and water for 20 seconds and avoiding contact with sick individuals can prevent infection.”

In the U.S., the CDC estimates that norovirus causes about 21 million illnesses, 465,000 emergency visits—mostly among children—and around 900 deaths annually.

What Is Norovirus And Its Common Symptoms?

Norovirus causes viral gastroenteritis, sometimes called “stomach flu” or a “stomach bug,” though it isn’t related to influenza. As per Mayo Clinic, it consists of several strains of RNA viruses that inflame the stomach and intestines, causing nausea, vomiting, and diarrhea.

Symptoms usually appear one to two days after exposure and often include:

• Nausea
• Vomiting (non-bloody)
• Watery diarrhea
• Stomach cramps
• Dehydration (rare but possible)
• Fever
• Headache
• Body aches

Most people recover within one to three days, though they can still spread the virus for up to two weeks after feeling better.

Who Gets Norovirus?

Anyone can get infected. Norovirus is the leading cause of acute gastroenteritis in the U.S., affecting all ages. Young children, older adults, pregnant people, and individuals with existing health conditions are more vulnerable.

How Does Norovirus Spread?

Norovirus spreads very easily. It survives well in the environment, and only a minuscule amount is enough to infect someone. In fact, just a few particles on the head of a pin can infect over 1,000 people.

Exposure can happen through:

• Eating contaminated water or food, especially leafy greens, fresh fruit, and shellfish like oysters
• Contact with vomit or fecal particles from someone who is infected, either by touching them directly or by touching contaminated surfaces, utensils, or toys

How Does Norovirus Affect Your Gut and Digestive System?

As per the National Institute Of Health, once inside the body, norovirus targets the stomach and intestines. It inflames the lining of the gut, which disrupts normal digestion and absorption. This inflammation leads to increased fluid secretion and faster movement through the intestines, causing watery diarrhea. Vomiting occurs as the stomach reacts to the irritation.

The gut lining may also temporarily lose some of its ability to absorb nutrients and fluids, which can lead to dehydration, electrolyte imbalances, and fatigue. While symptoms usually resolve in a few days, the virus can continue to be shed in stool for up to two weeks, meaning the gut can remain a source of infection even after recovery.
