High fever (hyperthermia) is one of the most frequent complaints faced during the cold and flu season. In connection with a fever, they call an ambulance or a district doctor for a house, they write out most of the disability certificates and student certificates. What can cause a temperature of 39 ° C, how to deal with it, when you need to see a doctor, and when you can try to solve the problem yourself?
Causes of a temperature of 39 ° C
Hyperthermia almost always indicates the presence of an infectious-inflammatory process in the body. The most common causes of body temperature rises to 39 ° C include:
- Acute respiratory viral infections (ARVI) – a wide group of diseases transmitted by airborne or contact by and having a similar clinical picture. High body temperature (39 ° C and above) is characteristic of influenza and adenovirus (a virus affecting the upper respiratory tract), less common in other acute respiratory viral infections (parainfluenza, rhinovirus, etc.). SARS is characterized by a combination of fever with catarrhal symptoms: runny nose, sore throat, cough.
- Sore throat – inflammation of the lymphoid tissue of the pharynx (most often – the palatine tonsils). Its main symptoms are fever, severe sore throat and severe intoxication (weakness, lack of appetite), the presence of raids or ulcers on the surface of the tonsils during examination of the throat.
- Inflammatory diseases of the respiratory system – bronchitis, pneumonia, pleurisy. With them, in addition to an increase in temperature, cough is almost always observed – dry or moist, sometimes painful, shortness of breath (frequent and difficult breathing) is often associated, chest pains are characteristic of pleurisy.
- Urinary tract infections – cystitis, pyelonephritis, in which patients are worried about fever, urination disorders (frequent, painful, with the release of changed urine), pain in the abdomen or lower back.
- Intestinal infections with vomiting and diarrhea.
- Meningitis – inflammation of the meninges – as an independent disease or as a complication of another infection (including influenza). It is characterized by an extremely serious condition, severe headache, vomiting, and convulsive syndrome.
- Other infections with characteristic symptoms of lesions of the inflamed organ.
In addition to the above processes, some other pathological conditions can lead to high temperatures: blood diseases, poisoning, etc. However, it is the common cold that is the most common cause of a rise in temperature to 39 ° C in adults and children.
Is the temperature at 39 ° C dangerous?
Severe hyperthermia with a body temperature of 39 ° C and above is always a dangerous condition. Such a fever indicates a serious infectious and inflammatory process, noted, including in severe flu and other acute respiratory viral infections. Temperature rise up to 39 ° C is possible against the background of the occurrence of cold complications – with the development of bronchitis, otitis, pneumonia, meningitis.
In addition, the temperature of 39 ° C itself is heavily tolerated, accompanied by headaches, weakness, nausea, aching bones and other unpleasant symptoms.
Temperature 39 ° C in a child
A temperature of 39 ° C in a child may appear for about the same reasons as in adults. In the first place are SARS, and severe fever in children can occur not only against the background of influenza and adenovirus infection, but also against other viral diseases (rhinovirus, parainfluenza, enterovirus), which in adults often occur with a low temperature.
Do not forget about childhood infections (chickenpox, measles, rubella, scarlet fever). Most of them, in addition to fever, are accompanied by the appearance of characteristic rashes on the skin and mucous membranes.
For a child, a temperature of 39 ° C is a much more dangerous condition than for an adult. With such indicators of the thermometer, children feel very bad, and in some cases, convulsive syndrome (febrile seizures) may develop and symptoms of irritation of the meninges occur: vomiting, photophobia, and an excruciating headache.
In order to avoid complications, it is impossible to prevent the child from raising the temperature further, and an antipyretic agent should be given already at 38 ° C.
From the first days of cold and flu, a child can take RINSASIP® for children, which contains paracetamol as a febrifuge. In addition to the latter, ascorbic acid and pheniramine, which reduces nasal congestion and runny nose, is a part of RINZASIP® for children.
Why can a temperature of 39 ° C flow without symptoms?
High body temperature is extremely rare with no other symptoms. However, asymptomatic or asymptomatic fever is possible in the following cases:
- With the flu – in the first 1-2 days it usually occurs without catarrhal symptoms, starting with a sharp rise in temperature. And only on the 3rd day of illness do snot, nasal congestion, dry cough and sore throat join. However, at the very early stages of a viral infection there are usually signs of intoxication – weakness, headache, even if moderately severe.
- With a reduced threshold of pain sensitivity, when the high temperature is not accompanied by a headache.
- With urinary tract infections.
- In case of fever of non-infectious origin (blood diseases, etc.).
A temperature of 39 ° C without symptoms that does not go away for 2 days or longer requires the obligatory treatment of a physician and an examination to determine the cause of the fever.
What if the temperature of 39 ° C does not pass for a long time?
With a typical cold and flu, fever bothers patients for 2–4 days, and then body temperature returns to normal. But what if this does not happen and the hyperthermia persists?
A temperature of 39 ° C, which lasts longer than 2–3 days, may indicate the development of complications of acute respiratory viral infection and flu or a misdiagnosis. To exclude bacterial complications (otitis, pneumonia, etc.) and to clarify the diagnosis with prolonged fever, it is necessary to consult a physician or a pediatrician.
Is it possible to shoot down the temperature of 39 ° C and with what?
The temperature of 39 ° C to bring down not only possible, but necessary. According to WHO recommendations, the indication for receiving antipyretic is a temperature in excess of 38 ° C in a child and in excess of 38.4 ° C in an adult.
What and how to bring down the temperature at home? In the first-aid kit everyone should have one of the antipyretic drugs:
- paracetamol and its derivatives (efferalgan, cefecon, panadol);
- ibuprofen (nurofen);
- nimesulide (nimulide, nimesil);
- combined means – ibuklin (ibuprofen plus paracetamol), etc.
A good variant of the combined remedy with antipyretic effect for complex therapy of colds and flu is RINSASIP® with vitamin C. It consists of:
- paracetamol, which provides antipyretic, analgesic and anti-inflammatory effects;
- Phenylephrine, which produces a vasoconstrictor effect, due to which the swelling of the mucous membranes of the nasopharynx is reduced and nasal breathing is facilitated;
- Pheniramine, able to reduce itching in the nose, eyes and throat, which helps reduce the redness and swelling of the eyelids and nose;
- caffeine, enhancing the analgesic effect of paracetamol 1;
- ascorbic acid is vitamin C, an increased amount of which is necessary for the body to successfully resist viral infections.
If there is no antipyretic drug on hand, the patient should be given plenty of warm drink (fractionally, in small sips), undress him and wipe with cool water (temperature around 20 ° C), allowing it to dry then. When evaporated from the surface of the body, the water will reduce the temperature by 1–2 ° C. During this time, one of the relatives will be able to reach the round-the-clock pharmacy and purchase the necessary drug. If the patient is alone at home, there is no antipyretic drugs, and rubbing does not help, you should immediately call an ambulance.
