Dengue fever in Sri Lanka. Dengue fever – Sri Lanka

The island of Sri Lanka is currently experiencing a serious outbreak of dengue fever. The National Dengue Control Team reports more than 107,000 dengue cases since January 1, 2017. The death toll currently stands at 269. In comparison, in 2016, only 55,150 cases of dengue fever were reported throughout the year.
Monsoon rains in May caused flooding and waterlogging that affected an estimated 600,000 people in 15 of the country's 25 districts. These were the worst monsoon rains in Sri Lanka since 2003. The presence of standing water and rain-soaked debris provided ideal breeding conditions for the Aedes mosquito, which transmits the dengue fever virus.
Now some more facts:
About 44% of the cases were reported in Western Province.
The highest number of cases were reported in the districts of Colombo (20,010 cases), Gampaha (13,401), Kurunegala (5,543), Ratnapura (5,512) and Kalathura (5,093).
The current outbreak is mainly due to dengue fever virus type 2 (DEN-2).

How Sri Lanka fights dengue fever

Dengue experts have been deployed to Sri Lanka by the World Health Organization (WHO). They visited the affected areas, analyzed the current situation and made recommendations to combat this outbreak. The Ministry of Health has launched an emergency response to the outbreak. It has increased the number of casualty beds, including temporary wards at Negombo Hospital, and created a new High Dependency Unit (HDU) for more serious dengue patients at the National Hospital.
Essential supplies and critical equipment for the treatment of dengue patients are being supplied to hospitals in Sri Lanka. The government deployed 450 military personnel to help clear breeding sites and train communities in clearing breeding sites.
Nearly 100 entomologists were mobilized from low-risk to high-risk areas to complete the entomological survey (insect survey).
WHO has provided 50 fog machines to provide more reliable vector control in areas particularly affected by the outbreak.

What you need to know about dengue fever

Dengue fever exists in many parts of the world: 2.5 billion people live in areas where dengue fever is transmitted, mainly in Southeast Asia, the Pacific Islands, Latin America, the Caribbean Islands, and now Africa and the Middle East. The World Health Organization (WHO) estimates that there are 50-100 million dengue infections worldwide each year.
Dengue is a viral disease and is transmitted through the bite of the Aedes mosquito. This mosquito lives very close to people in built-up areas and loves areas with stagnant water. The incubation period is usually 4-10 days.
Symptoms include high fever that can last 3 to 7 days, severe headache, muscle and joint pain, and eye pain.
Dengue fever is commonly known as "breaking bone fever" as those who have this fever often complain of severe bone pain. Nausea and vomiting may also occur. These symptoms are similar to those of malaria, so if you are in a malaria region, you should also get tested for malaria.
In most cases, dengue fever often improves within a few days. However, in 1-2% of cases, the disease may progress to a more severe condition called dengue hemorrhagic fever. In extreme cases, it can lead to death, but this outcome can usually be prevented with adequate medical care. A very small number of people who travel to countries with a risk of dengue fever (which includes Sri Lanka) become infected with dengue fever each year. Symptoms of the disease develop either while on holiday or after the traveler has returned to their home country.

To reduce your risk of contracting dengue fever, you should do the following:
1. Make sure there is no standing water near where you live. Water can collect in all sorts of containers, including discarded tires, jars, buckets and plant pots, especially during and after rainy seasons.
2. Follow bite prevention measures day and night. These include using effective repellents (mosquitoes that carry dengue tend to bite during the day, while mosquitoes that carry malaria are more active at night), wear long pants and long sleeves, and do not open a window for long periods unless it has a screen. , use air conditioning if available, and sleep under mosquito nets.

If you suspect you have been exposed to dengue fever, seek medical attention immediately. Be sure to drink plenty of fluids. In Sri Lanka you will also need to take a malaria test as the symptoms of dengue fever and malaria can be similar.
Full recovery from dengue may take weeks, during which time your energy levels will be significantly reduced. Give yourself enough time to fully recover.

The Federal Service for Surveillance on Consumer Rights Protection and Human Welfare informs that in countries with tropical and subtropical climates, epidemiological problems with Dengue fever have continued in recent years.

Dengue fever is widespread in Southeast Asia (Thailand, Indonesia, China, Malaysia, Japan, Vietnam, Myanmar, Singapore, Philippines), India, Africa (Mozambique, Sudan, Egypt), in the tropical and subtropical zones of the North, Central and South America (Mexico, Honduras, Costa Rica, Puerto Rico, Panama, Brazil, etc.)

There is currently an outbreak of dengue fever in Sri Lanka, where 48 thousand diseases with 77 deaths have been registered. 10 of the country's 25 districts are at risk. The situation is particularly bad in the Western Province in the Kanutari region. The increase in incidence is associated with the peculiarities of the epidemiological process, which are characterized by seasonality.

In recent years, the countries of Southeast Asia have been particularly popular among Russian tourists.

In recent years, imported cases of dengue fever have begun to be registered in the Russian Federation, including 63 cases in 2012, 170 in 2013, 105 cases in 2014, 136 in 2015, and 125 in 11 months of 2016. Infection occurred when visiting Thailand, Vietnam, Indonesia, India, Bangladesh, Hong Kong, and the Maldives.

The main carriers of dengue fever are the Aedes aegypti mosquito. In the absence of a carrier, a sick person does not pose an epidemiological danger.

Dengue fever is a viral infection transmitted by mosquito bites. Symptoms include high fever, nausea, rash, headaches and lumbar pain. The hemorrhagic variant of fever is accompanied by severe internal bleeding caused by the collapse of blood vessels.

In order to prevent dengue fever and other hemorrhagic fevers with vector-borne transmission among Russian tourists traveling to Peru, Thailand, Indonesia, India, Vietnam, Bangladesh, Hong Kong and other countries with tropical climates, it is necessary:

When traveling to countries with tropical climates, inquire about the possibility of contracting hemorrhagic fevers through transmissible transmission;

Use personal protective equipment, such as: window mosquito nets, curtains, long sleeves, insecticide-treated materials, repellents;

Upon return, if the temperature rises, inform the doctor about the fact of being in a country with a tropical climate.

The situation remains under the control of the Federal Service for Surveillance on Consumer Rights Protection and Human Welfare.

In Sri Lanka, due to the outbreak of Dengue hemorrhagic fever, an extremely unfavorable epidemiological situation has developed.

This dangerous infection is transmitted through a mosquito bite.

We draw the attention of tourists traveling to Sri Lanka to the need to observe appropriate preventive measures.

Dengue fever (bone fever, joint fever, giraffe fever, five-day fever, seven-day fever, date disease) acute vector-borne viral disease. Occurs with fever, intoxication, myalgia, arthralgia, rash and swollen lymph nodes. In some variants of Dengue fever, hemorrhagic syndrome develops.

The incubation period lasts from 3 to 15 days (usually 5-7 days). The disease usually begins suddenly. Only in some patients, mildly expressed prodromal phenomena in the form of weakness and headache are observed within 6-10 hours. Usually, in the midst of complete health, chills and pain in the back, sacrum, spine, and joints (especially the knees) appear. Fever is observed in all patients, body temperature quickly rises to 39-40°C. Severe adynamia, anorexia, nausea, dizziness, insomnia are noted; in most patients there is hyperemia and pastiness of the face, injection of scleral vessels, hyperemia of the pharynx.

An increased incidence of dengue fever has been recorded in Sri Lanka, reports Rospotrebnadzor...

The agency calls on Russians in Southeast Asian countries to observe security measures.

According to Rospotrebnadzor, an outbreak of dengue fever has been recorded in Sri Lanka. The disease was detected in 48 thousand people, 77 of them died as a result. The fever has spread to 10 of Sri Lanka's 25 districts. The most unfavorable situation has developed in the Western Province in the Kanutari region. Due to the characteristics of the fever, this outbreak is seasonal.

Rospotrebnadzor emphasized that recently the tourist flow of Russians to Southeast Asia has increased.

The agency recommends that compatriots traveling to Thailand, India, Bangladesh, Peru, Indonesia, Vietnam, Hong Kong and other countries with a tropical climate take preventive measures. This will help prevent infection with Dengue fever and other hemorrhagic fevers transmitted by vectors. It is necessary to wear long sleeves, use repellents, and install mosquito nets on windows. When returning from the country, you need to listen to your health, and if your temperature rises, tell your doctor about your trip.
