France reports 10 cases of dengue fever in Sainte-Cecile-les-Vignes

France has recorded 10 cases of dengue fever in the southeastern town of Sainte-Cecile-les-Vignes, French media reported.

The first case in the series was reported by a health official on August 14, helping authorities identify an imported case and nine new cases of the autochthonous disease in the same area, the Provence-Alpes-Côte d’Azur regional health agency said on Thursday.

Authorities carried out larvicide operations in the city to eliminate possibly infected mosquitoes and thus prevent the spread of the disease.

The total number of autochthonous dengue fever cases in the metropolis has risen to 16 this year, according to broadcaster France Info. The country’s first autochthonous case of 2024 was reported on July 8 in the southern department of Hérault.

France’s public health agency (Sante Publique France or SPF) previously announced that 1,031 imported cases were detected between May 1 and August 13.

An “autochthonous” case is defined as a person infected within France, without travelling to infected areas of the world in the 15 days before the onset of symptoms.

Dengue fever is a viral disease that is prevalent in South-East Asia and the Pacific, Central and South America, and countries in Africa. The fever is not transmitted from person to person, but only through mosquito bites.

There is no specific treatment for dengue, but essential care actions such as timely diagnosis of cases, recognising the signs of severe dengue onset and appropriate management of those who become ill can help prevent severe dengue from developing and causing death from dengue.

Understanding Dengue Causes and Effective Prevention Strategies

Dr Vaidya's Laboratory in Thane provides comprehensive diagnostic services, particularly during the monsoon season when dengue fever cases spike. Dengue fever is a significant health concern caused by the dengue virus and transmitted by Aedes mosquitoes. Understanding the causes of dengue is crucial for implementing effective prevention strategies.

What are the Causes of Dengue?

Dengue fever is caused by the dengue virus, which belongs to the Flavivirus genus. The virus is transmitted to humans through the bites of infected Aedes mosquitoes, primarily Aedes aegypti and Aedes albopictus. Here are the key factors contributing to the spread of dengue:

Transmission by Aedes Mosquitoes: The primary cause of dengue is the bite of an infected Aedes mosquito. These mosquitoes breed in stagnant water in containers such as flower pots, old tyres, buckets, and clogged drains. They are most active during the early morning and late afternoon, making these times the most risky for mosquito bites.

Virus Serotypes: Dengue virus has four distinct serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. Infection with one serotype provides lifelong immunity to that specific serotype but not others. This means a person can be infected with dengue up to four times in their lifetime, each time with a different serotype.

Urbanisation and Population Density: Rapid urbanisation and increasing population density create ideal conditions for the spread of dengue. Crowded living conditions, inadequate waste disposal, and poor water management can lead to the accumulation of stagnant water, providing breeding sites for Aedes mosquitoes.

Climate Factors: The monsoon season, characterised by heavy rainfall and increased humidity, significantly contributes to the rise in dengue cases. The wet conditions create numerous breeding grounds for mosquitoes, leading to a surge in mosquito populations and, consequently, dengue transmission.

Travel and Migration: International travel and migration can facilitate the spread of the dengue virus to non-endemic areas. Travellers from dengue-endemic regions can introduce the virus to new places, leading to outbreaks.

Infected Humans: Once a person is infected with the dengue virus, they become a carrier and can transmit the virus to mosquitoes when bitten. These mosquitoes can then bite other humans, perpetuating the cycle of transmission. This human-mosquito-human transmission cycle is the primary mode of dengue spread.

Lack of Effective Vector Control: Ineffective mosquito control measures contribute to the persistence and spread of dengue. Without proper vector control, mosquito populations can grow unchecked, increasing the risk of dengue transmission. Effective measures include regular insecticide spraying, eliminating stagnant water, and promoting the use of mosquito nets and repellents.

Socioeconomic Factors: Lower socioeconomic conditions often correlate with inadequate housing, poor sanitation, and limited access to healthcare, all of which can contribute to the spread of dengue. Communities with limited resources may need help implementing effective mosquito control measures, leading to higher rates of dengue infection.

Dengue – Frequently Asked Questions

In recent days, Tamil Nadu has witnessed a marginal spike in dengue fever cases, affecting individuals of all ages – including Children and Adults.

This mosquito-borne infection has become a significant concern, exacerbated by various factors. One such is climate change, i.e., during the monsoon season, the outbreak of dengue is high.

Aedes mosquitoes, especially Aedes aegypti and Aedes albopictus, are the primary causes behind the spread of dengue through their bites.

Concerning this health concern, understanding its signs and symptoms, causes, diagnosis, and preventive measures is essential in mitigating its impact and preventing its spread.

Here are some frequently asked questions about dengue fever that can help you understand better.

Can Dengue Spread From Person To Person?

Dengue fever is primarily transmitted through mosquito bites, specifically those of Aedes mosquitoes. However, there are exceptional cases where the virus can be transmitted in different ways. For instance, if a pregnant woman contracts dengue, the virus can pass to her baby during pregnancy or around the time of birth. Additionally, though rare, dengue can be spread through blood transfusions.

Can Dengue Mosquito Bite At Night?

Dengue is primarily a daytime-biting mosquito-borne disease.

However, Aedes Aegypti, which is responsible for transmitting dengue stays active during peak times such as early morning (two hours after sunrise) and late afternoon (two hours before sunset).

What Is The First Sign Of Dengue Fever?

Dengue symptoms can range from mild to severe. And some individuals, especially children and teenagers, may not exhibit any signs of the disease at the earliest. Gradually the symptoms start to appear four to seven days after being bitten by an infected mosquito. In its milder form, dengue presents as a High Fever (often around 104°F) accompanied by any of the following seven warning signs:

Headache

Muscle, bone, and joint pain

Nausea

Vomiting

Pain behind the eyes

Swollen glands

Rash

In rare and severe cases, the disease can progress to hemorrhagic fever, leading to damaged and leaky blood vessels, severe bleeding, a sudden drop in blood pressure, and even death.

Can Dengue Fever Occur To The Same Person Twice?

Yes, a person can be infected with Dengue multiple times, as there are four different serotypes of the Dengue virus (DENV-1, DENV-2, DENV-3, and DENV-4).

Each serotype can cause the disease, and previous infection with one serotype does not provide complete immunity against the others. Some reinfections can result in more severe forms of the disease, particularly with the D2 strain, which is associated with symptoms like Dengue Hemorrhagic Fever and Dengue Shock Syndrome.

Immune complications may also occur in some cases, making reinfections more severe.

Do Platelets Decrease Because Of Dengue Fever?

Dengue fever can lead to a significant drop in platelet count in the bloodstream. As it affects the bone marrow, which is the site for the formation of platelets, platelet production reduces. Despite this, it can even increase the platelet destruction from peripheral blood.

These results in a condition termed Thrombocytopenia, occurring when the platelet count is low in the blood. As a result, it increases the risk of internal bleeding.

If this is the worst case, platelet transfusion may be necessary.

Can Dengue Be Prevented?

Preventing dengue primarily involves measures to protect yourself from mosquito bites and eliminate mosquito breeding sites. Here’s what you can do:

Stay in air-conditioned rooms or ensure that doors are closed if you don’t have air conditioning.

Limit outdoor activities, especially during dawn and dusk when mosquitoes are most active.

Wear protective clothing such as long-sleeved shirts and pants, to cover up the exposed skin.

Use mosquito repellent on exposed skin, and consider applying permethrin to clothing, shoes, camping gear, and bed netting.

Make your living environment free from mosquito breeding sites. Aedes mosquitoes often breed in stagnant water in items like automobile tires, air coolers, and flower vases. Regularly empty and clean these containers and keep them covered between cleanings.

Is Dengue A Fatal Disease?

The person suffering from dengue can recover completely as its symptoms can be managed by staying hydrated and taking medications as prescribed by the healthcare provider.

However, in some cases, Dengue can progress to conditions like Dengue Hemorrhagic fever and Dengue Shock syndrome. When left untreated, it can pose a risk to one’s health.

Early diagnosis, appropriate treatment, and the right medications can reduce the risk in severe cases.

How Is Dengue Diagnosed?

Early and accurate diagnosis of dengue is important for effective management and timely treatment.

When you seek medical assistance because of the concerning symptoms, the healthcare professionals will evaluate your symptoms, medical history, and recent travel history to regions where dengue is prevalent. While these symptoms can overlap with other illnesses, they provide important initial clues for diagnosis.

Followed by blood tests for dengue. This includes the following:

Antigen Test: This test identifies the presence of the dengue virus in a patient’s blood.

Polymerase Chain Reaction (PCR) Test: PCR is a molecular test that detects the genetic material of the dengue virus.

What Are The Treatment Options For Dengue Fever?

There is no specific antiviral treatment for dengue. In mild cases, patients are advised to stay hydrated to prevent dehydration and manage their symptoms with medications. However, in severe cases, hospitalization may be necessary, with treatment including intravenous (IV) fluid and electrolyte replacement, blood pressure monitoring, and blood transfusion to address complications.

When Should I Consult A Doctor?

Many people tend to overlook the symptoms of dengue fever. It’s crucial to consult a doctor if experiencing fever for more than 3 days. Never even neglect the mild symptoms; diagnose early and prevent the potential complications that arise because of dengue.

What Precautions Should Be Taken After Recovering From Dengue?

Eat a well-balanced diet with plenty of fruits and vegetables to help boost your immune system, which even helps you in the recovery phase.

Make sure to include adequate vitamins and minerals in your diet. Avoid oil and junk foods.

Hydrate yourself by drinking water, and healthy & refreshing juices.

Ensure your body gets sufficient rest to aid your recovery and regain strength.

Always follow the guidance and medications prescribed by your healthcare provider during and after the illness.

During the recovery phase, the body may still be weak, so excessive physical exertion should be avoided. Instead, walking or light exercise can be practiced.

Which Signs Include That We Are Cured From Dengue?

The patient begins to regain the lost function.

During the recovery phase, which typically occurs 7 days after the onset of Dengue, the patient’s condition gradually improves. This includes the subsiding of fever, increased urination, and a returning appetite.

In rare cases, even after crossing the recovery phase, if you encounter any of the following symptoms, seek immediate medical attention:

Decreased urination

Few or no tears

Dry mouth or lips

Lethargy or confusion

Cold or clammy extremities

Shifting patterns of dengue three years after Zika virus emergence in Brazil

In 2015, the Zika virus (ZIKV) emerged in Brazil, leading to widespread outbreaks in Latin America. Following this, many countries in these regions reported a significant drop in the circulation of dengue virus (DENV), which resurged in 2018-2019. We examine age-specific incidence data to investigate changes in DENV epidemiology before and after the emergence of ZIKV. We observe that incidence of DENV was concentrated in younger individuals during resurgence compared to 2013-2015. This trend was more pronounced in Brazilian states that had experienced larger ZIKV outbreaks. Using a mathematical model, we show that ZIKV-induced cross-protection alone, often invoked to explain DENV decline across Latin America, cannot explain the observed age-shift without also assuming some form of disease enhancement. Our results suggest that a sudden accumulation of population-level immunity to ZIKV could suppress DENV and reduce the mean age of DENV incidence via both protective and disease-enhancing interactions.
