Rubella is an infectious disease, usually common in children. Symptoms of rubella include headache, low fever, fatigue, and occasionally diarrhea.
Besides, is rubella contagious? How is rubella caused? What should one do if infected with rubella? Rubella is an acute contagious disease caused by the rubella virus. Symptoms include low fever and lymph node enlargement. Generally, the course of a mild case of rubella is short, and it can be quickly cured through scientific treatment. However, for pregnant women, experiencing rubella can have a significant impact on the fetus. So, is rubella contagious? The answer is yes.
Rubella virus, a virus that can only be transmitted to humans, is transmitted from mouth and nose secretions to others or through droplets.
Rubella virus can survive in the placenta or fetus and cause chronic progressive infection in various systems for years after birth.
Rubella virus can grow in cell culture of rabbit kidney, swine kidney, green monkey kidney, rabbit cornea and can agglutinate chicken, pigeon, geese and human "O"-cell red blood cell.
Rubella virus has low virulence in vitro.
Human beings are the only natural host of rubella virus, which spreads through droplets and is most contagious in the days before, during, and after the rash appears.
Viruses are also present in nasal pharyngeal secretions, blood, feces, and urine; subclinical patients are also contagious.
The disease is commonly manifested in winter and spring seasons, predominantly affecting children aged l to 5 years old, with equal incidence rates in both male and female.
Mother's antibodies can protect infants from illness within 6 months.
After the widespread use of vaccines, there is a decrease in incidence rates and an increase in the age at which disease occurs.
Primary infections during pregnancy can lead to fetal intrauterine infection, with the incidence and teratogenicity closely related to the gestational age at the time of infection, peaking in early pregnancy.
Congenital rubella infants may still shed the virus for several months after birth and are contagious during this period.
Rubella virus mostly spreads through respiratory droplets. It usually presents with upper respiratory tract infections such as cough, sneezing, runny nose, sore throat, headache, and low fever.
The above symptoms appear within 1-2 days, and the rash begins. The rash is pale red, slightly raised, and evenly distributed.
Rubella is a common disease, many people have been infected with the virus. The transmission route of rubella virus is broad, including droplet transmission and others. So, how does rubella spread? What are its transmission routes? Below, we will introduce them one by one.
1. The patient with rubella is the only source of infection, including subclinical or latent carriers. The actual number of infected individuals is actually higher than that of those who have been diagnosed with the disease. Therefore, this is an important source of infection that is often overlooked.
The infectious period is from 5 to 7 days before the onset of symptoms and 3 to 5 days after the onset, with the highest infectivity occurring on the day of onset and the day before.
Viruses can be isolated from the secretions of the mouth, nose, throat, and urine and feces.
2. Transmission Pathways: RHD is primarily transmitted through respiratory droplets, with close contact between individuals also leading to transmission via contact.
Newborns who are infected in the womb, especially in the throat, can excrete the virus for weeks, months, or even more than a year. Therefore, they can infect medical and family members who lack antibodies through contaminated bottles, nipples, clothing, diapers, and direct contact, or cause transmission in the baby's room.
Fetal infection may cause miscarriage, stillbirth, premature delivery or antenatally diagnosed congenital rubella syndrome.
3. Susceptible Populations: Rubella is generally more common in children aged 5 to 9 years, but it can also occur in middle and elderly adults during epidemic periods.
Rubella, which is more common in winter and spring.
In recent years, the incidence has been higher in spring and summer, which can be prevalent in gathering groups such as kindergartens, schools, and military units.
Rubella is a highly contagious, acute infectious disease that is most common among children. In spring, it is essential to prevent the occurrence of rubella promptly, especially in schools where an outbreak occurs, and to treat it immediately upon detection.
Rubella, caused by the Chiyou Rubella Virus, is a type of acute infectious disease that can significantly harm our health. Moreover, if a pregnant woman contracts rubella during pregnancy, it can also endanger the health of the fetus. Therefore, we must take preventive and health care measures in our daily lives.
Below, we will delve into the details of understanding symptoms associated with rubella.
Rubella, a common acute infectious disease caused by rubella virus, is characterized by low fever and generalized rash. It often accompanies lymphadenopathy in the occipital region and at the back of the neck.
Symptoms are usually mild and short, and are often considered trivial. However, in the early stages of pregnancy, infection with rubella can severely harm fetuses and cause congenital rubella syndrome.
The incubation period of rubella is 16 to 21 days, averaging 18 days. Infected with rubella virus in preschool children and adolescents, there are often mild prodromal symptoms such as fever, headache, sore throat, runny nose, etc.
Lymphadenopathy below the skull, behind the ear, and in the neck.
Approximately 1 to 2 days later, rashes starting at the facial and neck areas develop as pale red papules and maculopapules.
24 hours, spreading from the trunk to the limbs.
The rash is characterized by a short duration and rapid disappearance.
The rash on the body can merge, while the rash on the limbs is scattered but not fused.
On the third day, the rash usually subsides rapidly without leaving any trace, and sometimes there is mild flaking.
Needle sized red petechiae can be seen on the soft palate, and the rash disappears as soon as the prodromal symptoms appear. However, lymph node enlargement persists for a long time, accompanied by tenderness but not suppuration.
Rubella is a benign infectious disease, generally with a good prognosis and few complications. However, it can sometimes cause complications such as bronchitis, otitis media, joint pain, and purpura.
Women who have contracted rubella during early pregnancy (4 months) can suffer from miscarriage, premature delivery, stillbirth and fetal malformations.
To effectively treat and prevent rubella, it is essential to understand its symptoms. Only by recognizing these can one identify whether they are susceptible to the disease in their daily lives. Active prevention and treatment are necessary to significantly reduce the harm caused by rubella.
How is rubella treated? Many people are concerned about the most effective treatment for rubella. The most effective treatment is mainly symptomatic treatment.
What specific treatment should be administered for rubella? 1. General therapy: Patients with rubella usually present with mild symptoms and do not require specific treatment.
For patients with more significant symptoms, they should be bedridden and consume a liquid or semi-liquid diet.
For patients with high fever, headache, cough and conjunctivitis, symptomatic treatment should be provided.
2. Complication treatment, those with complications such as high fever, drowsiness, coma, convulsions in encephalitis should be treated according to principles of epidemic japanese encephalitis.
For those with severe bleeding tendency, adrenal cortex hormone therapy can be used, and fresh whole blood transfusion may be necessary.
3. Congenital rubella requires proper nursing and education. Medical personnel should closely collaborate with the parents, childcare providers, and school teachers to monitor the child's development, assess hearing, correct deformities, and, where necessary, perform surgical interventions for conditions such as glaucoma, cataracts, and congenital heart disease.
4. Medical treatment, in addition to symptomatic treatment, interferon and ribavirin may be beneficial in alleviating the condition.
5. Symptomatic treatment, isolation of the patient, bed rest, adequate hydration, and appropriate administration of antipyretics; pain in the head, arthralgia, and muscle pain require the use of analgesics, with topical calamine lotion.
Patients with severe disease may be given intravenous immunoglobulin or adult serum (20-40ml) or a attenuated live vaccine.
It is very important for pregnant women to prevent erythema infectiosum. If they have contact with the patient of erythema infectiosum, they should immediately be given immune globulin or placental globulin.
Patients in early pregnancy should opt for termination of pregnancy or abortion to prevent congenital rubella syndrome.
Prevention and Treatment of Reye's Disease in Children: Reye's disease is a common viral infectious disease in children, characterized by minimal systemic symptoms, red maculopapular rashes on the skin, and enlarged lymph nodes behind the ears, nape, and neck with tenderness, accompanied by few complications.
In the early stages of pregnancy, infection with rubella virus can be transmitted through the placenta to the fetus, resulting in various congenital defects known as congenital rubella syndrome.
Although rubella does not have specific drugs, it is mainly treated with symptomatic and supportive measures.
Children with congenital rubella are long-term carriers of the virus and can affect their growth and development. Early detection of visual and auditory impairments is essential, along with provision of special education and treatment to enhance their quality of life.
However, preventive care can be achieved through vaccination. How can we prevent chickenpox in children? 1. Active immunization: The live-attenuated rubella vaccine has been proven to be safe and effective.
The positive rate of antibodies after vaccination can reach more than 95%, and the antibodies can last for more than 7 years.
Vaccination with the live attenuated rubella vaccine is the primary measure to prevent rubella, which targets children aged from 1 to 12 years and susceptible women of childbearing age.
Or use the measles, rubella and mumps trivalent vaccine, which can reduce the number of vaccinations needed for children.
2. Passive Immunity: As the rash associated with rubella in children is milder and does not require passive immunity, the efficacy of passive immunization with immunoglobulins remains uncertain.
In daily life, the best way to control rubella in children is to cut off the source of infection. When taking care of children, special attention should be paid not to bring them to crowded places. More importantly, do not come into contact with carriers of rubella in children, so as to effectively control the source of the disease.
