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 takeaway coffee cup in your hand may be releasing a sea of microplastics into your body every time you take a sip, a new study reveals.

Microplastics are essentially fragments of plastic that are between 1 nanometer and 5 millimetres wide and can found in water, soil and the air. Experts estimate that about 2.7 million tonnes of microplastics seeped into the environment in 2020, an estimate expected to double by 2040.

These fragments carry toxic chemicals and can disrupt internal biological processes, leading to inflammation, cell death, organ dysfunction, heart attacks and reproductive issues in humans. Scientists have also found links between microplastics and cancer.

While researchers have long claimed that microplastics can enter the human body through contaminated food and water, a new Australian study suggests it can also enter through hot coffee cups.

Why Are Plastic Coffee Cups Dangerous?

Xiangyu Liu, study co-author and research fellow at School of Environment and Science and Australian Rivers Institute, Griffith University, Nathan, said this was due to heat.

The team conducted a a meta-analysis on existing research and analyzed data from 30 peer-reviewed studies. During this time, they focused on how common plastics such as polyethylene and polypropylene behave under different conditions, primarily temperature.

As the temperature of the liquid inside a container increased they noticed that the release of microplastics generally increases too. In the studies reviewed, reported releases ranged from a few hundred particles to more than 8 million particles per litre, depending on the material and study design.

Interestingly, 'soaking time' or the amount of time the drink sits in the cup was not a consistent driver, suggesting that leaving a hot drink in a plastic cup for a long time is not as important as the initial temperature of the liquid when it first hits the plastic.

After testing nearly 400 different cups, they found that if someone drinks '300 millilitres of coffee in a cup made of polyethylene per day, they could ingest 363,000 pieces of microplastic particles every year', according to Liu

What Can Be Done To Reduce Risks?

The team recommends using a reusable cup made of stainless steel, ceramic, or glass, as these materials do not shed microplastics for hot drinks. If you must use a disposable cup, its is better to drink out of a plastic-lined paper cup as they shed fewer particles than pure plastic cups, though neither is microplastic free.

They also advise not pouring putting boiling liquids directly into plastic-lined containers. Telling the barista to make your morning coffee slightly cooler before it hits the cup can reduce the physical stress on the plastic lining and lower overall exposure.

A dangerous, drug-resistant fungus has infected more than 7,000 people across 27 US states, including Mississippi, in 2025, federal health data shows. The infection, known as Candida auris, is classified as an “emerging infectious disease,” after doctors and public health experts noted a steady rise in cases since 2019, according to specialists at the Cleveland Clinic.

As of December 20, Mississippi had reported 108 cases of the fungal infection, based on figures from the Centers for Disease Control and Prevention. Here is what you need to know about Candida auris cases in Mississippi.

What Is Candida Auris?

Treating it is challenging because the organism can adapt to medications meant to eliminate it, health experts note. C. auris mainly affects people with serious underlying health problems and those using invasive medical devices such as ventilators, feeding tubes, or catheters, according to the CDC.

The fungus spreads through contact with contaminated surfaces and objects and can remain on a person’s skin or other body areas even when no symptoms are present. Experts say healthcare workers and visitors are not considered at risk of becoming infected.

Candida Auris: What Are The Symptoms?

Symptoms of Candida auris are not always noticeable, but when they do appear, they may include the following, according to the Cleveland Clinic:

• Ear infections
• Wound infections
• Urinary tract infections
• Blood infections that spread throughout the body

Candida Auris: How Can It Be Prevented?

• Regular hand hygiene using alcohol-based hand sanitizer
• Isolating patients who test positive for C. auris
• Frequent and thorough cleaning of patient rooms
• Using gloves and gowns while providing care
• Ensuring visitors clean their hands with soap and water or alcohol-based sanitizer

According to CDC data as of December 20, cases have been reported in the following states:

• Pennsylvania
• Illinois
• Indiana
• Michigan
• Ohio
• Wisconsin
• Iowa
• Kansas

Drug Resistance For Candida Auris Grows

Candida auris, often referred to as a “superbug fungus,” is continuing to spread worldwide and is becoming increasingly resistant to both antifungal drugs and the human immune response, researchers at the Hackensack Meridian Center for Discovery and Innovation said in a review published in early December.

The findings support earlier CDC warnings that labeled C. auris an “urgent antimicrobial threat,” making it the first fungal pathogen to receive that classification, as case numbers have climbed sharply in the United States, especially in hospitals and long-term care facilities.

The review, published in the journal Microbiology and Molecular Biology Reviews, explains why the fungus is so difficult to control and highlights how outdated testing methods and limited treatment options have failed to keep pace. The research was led by Dr. Neeraj Chauhan of Hackensack Meridian CDI in New Jersey, Dr. Anuradha Chowdhary from the University of Delhi’s Medical Mycology Unit, and Dr. Michail Lionakis, head of the clinical mycology program at the National Institutes of Health.

In their statement, reported by Fox News, the researchers emphasized the urgent need to develop new antifungal drugs with broad effectiveness, improve diagnostic tools, and explore immune-based and vaccine-related treatments to better protect high-risk patients.

While doctors across the world recommend ensuring that fluoride and other protective minerals make up your toothpaste, your body produces its very own amino acid that protect your entire dental cavity.

Arginine, an amino acid that is already present in saliva, can turn bacteria from damaging to protective in your mouth, a study has found.

When sugars from food are broken down by the many bacteria living in the mouth, acids are produced that gradually damage tooth enamel and lead to cavities. This is known as dental caries. Over time, this acid dissolves tooth enamel and causes cavities.

However, researchers at Aarhus University in Denmark have discovered that regular arginine treatment can significantly reduced the overall acidity levels in the mouth and prevent tooth decay.

Yumi Del Rey, microbiologist at Aarhus, said: ""Our results revealed differences in acidity of the biofilms, with the ones treated with arginine being significantly more protected against acidification caused by sugar metabolism."

How Did The Study Take Place?

Volunteers were then asked to instructed to dip the dentures in a sugar solution for 5 minutes, immediately followed by distilled water (as placebo) or arginine for 30 minutes, one on each side. This was to be repeated three times a day, with arginine treatment done on the same side each time.

Sebastian Schlafer, professor at the Department of Dentistry and Oral Health, explained: "The aim was to investigate the impact of arginine treatment on the acidity, type of bacteria, and the carbohydrate matrix of biofilms from patients with active caries."

After 4 days of this process, the biofilms were developed and the dentures were removed for detailed analysis. The researchers compared dental plaques grown on customized dentures on both sides of each participant's mouth using a special pH-sensitive dye called C-SNARF-4.

How Does Arginine Work?

Additionally, the team also began to look into how arginine might be reducing acidity, by taking stock of which bacteria and sugars were present in each sample.

Biofilms treated with arginine showed lower levels of a sugar called fucose, while another sugar, galactose, was concentrated towards the outer surface of the biofilm, meaning both sugars were away from the tooth enamel.

After analyzing the DNA of bacteria present, the researchers found that arginine treatment significantly reduced a specific population of Streptococcus bacteria known to produce acid, while slightly increasing other bacterial strains that can metabolize arginine.

The scientists noted that while more research is needed into the arginine's effectiveness, the amino acid could be a promising new addition to oral hygiene products such as toothpaste or mouthwash.
