Dengue Fever: Warning Signs and Blood Tests Explained

Dengue fever is a viral illness that has the ability to spread extremely fast, particularly in tropical and subtropical nations such as India. It is brought about by the sting of contaminated mosquitoes like Aedes aegypti. Cases of dengue are high in the monsoon and post-monsoon seasons. This is why awareness and early detection are very important. The dengue cases that arise are mostly mild, but others may be severe and life-threatening unless they are properly treated.

What Causes Dengue Fever?

There were red flags as the disease progressed, which could be regarded as some of the signs of a severe form of dengue. Unstopping vomiting, abdominal agonizing pains, and breathlessness are life-threatening symptoms and medical attention. Bleeding may also be experienced by bleeding moist gums, nose bleeding, or bleeding/easy bruising. 

Early Symptoms of Dengue

Such symptoms can be the signs of complications like Dengue Hemorrhagic Fever, which can cause bleeding of internal organs and shock. A sharp deviation towards a low number of plates is another essential indication. Patients may feel very weak, agitated, or sleepy. In severe instances, it can lead to dengue shock syndrome, which is a health crisis.

Warning Signs You Should Not Ignore

As the disease advanced, there were some red flags that could be taken as evidence of a serious form of dengue. Incessant vomiting, excruciating pain in the abdomen, and breathlessness are life-threatening symptoms that should prompt medical intervention. Symptoms of bleeding, such as nose bleeding, bleeding gums, or easy bruising, can also be experienced. 

These symptoms may be indicative of complications such as Dengue Hemorrhagic Fever that may cause bleeding of the internal organs and shock. Another critical sign is a sudden change towards a low number of plates. Patients can experience a great sense of weakness, agitation, or drowsiness. In extreme cases, it may develop into dengue shock syndrome, which is a health emergency.

Importance of Early Diagnosis

Dengue diagnosis needs to be done early to avoid complications. Its symptoms are similar to those of other viral infections, and as such, laboratory tests are necessary to confirm. Soon, the doctors can identify the level of platelets in the circulation, treat the symptoms, and make sure that the disease does not become serious. Late diagnosis may pose a danger to possible complications and recovery.

Key Blood Tests for Dengue

NS1 Antigen Test

Despite the numerous tests available to detect dengue infection, one of the most used tests is the NS1 Antigen Test. It determines a particular protein secreted by the dengue virus into the blood. The test tests best in the first 1-5 days of infection, and it aids in the early diagnosis of the infection before antibodies develop.

IgM and IgG Antibody Tests

Dengue IgM Test and Dengue IgG Test are tests that detect antibodies that the body produces due to vulnerability to the virus. IgM antibodies tend to appear 4-5days after infection and will show the recent infection. IgG antibodies are late to develop and can indicate previous infection or secondary infection with dengue.

Complete Blood Count (CBC)

CBC is a common test that is very critical in the management of dengue. It assists in checking the level of platelets and white blood cells, as well as hematocrit. A characteristic of dengue is a serious reduction in the number of platelets ( thrombocytopenia ). A rise in hematocrit level can be an indicator of plasma leakage, which is a symptom of severe dengue.

Platelet Count Monitoring

They should closely check the platelet levels of the dengue patients. Although the low number of platelets is alarming, it cannot be the only factor in the severity. Physicians also evaluate clinical symptoms and other blood parameters, which they use to determine treatment.

Who is at Higher Risk?

Some are more vulnerable to severe dengue. Those who are the most at risk are children, the elderly, and those who have weakened immunity. The individuals who have suffered past dengue infections have higher chances of contracting complications in the latter infections. Residing in places with poor sanitation and stagnant water elevates chances of being exposed to breeding grounds of the mosquitoes, and this further increases the chances of contracting the disease.

Prevention and Safety Measures

You should avoid mosquito bites and their breeding as the first step in preventing dengue. You can do this by using mosquito repellents, wearing full-sleeved clothes, and bed nets, etc.

You should remove stagnant water from your surroundings, such as in coolers, flower pots, containers, etc., and any other places where mosquitoes can breed. To prevent dengue, awareness and hygiene at the community level are important. 

Conclusion

Dengue fever is a preventable, serious, and manageable disease when detected early. Early warning signs and blood investigations can be instrumental in the results of treatment. Knowing the use of diagnostic tests, such as NS1 antigen, antibody tests, and CBC, will aid in confirming and successfully tracking the disease at an early stage. Through proper care and awareness, preventive strategies can help avoid dengue effects, which brings about better health and security to the people and society.
