These diseases are especially susceptible to children and frail people.

What is foot and mouth disease?

Hand, foot and mouth disease - is an infectious disease caused by enterovirus, which can cause fever, rashes, ulcers on the hands, feet, mouth and other parts of the body. Individual patients can cause myocarditis, pulmonary edema, aseptic meningoencephalitis and other complications. The condition of some severely ill children develops rapidly and leads to death.

Hand, foot and mouth disease is more likely to occur in children under 10 years old, with the highest incidence occurring in young children.

Hand, foot and mouth disease is not a rare disease

Hand, foot and mouth disease is actually a common disease caused by enteroviruses, just like the common cold.

Characteristics of hand, foot and mouth disease

The early onset of the disease is a bit like a cold, with acute onset and fever, usually around 38°C.

After the herpes in the mouth breaks out, ulcers will appear, and the person will often drool and be unable to eat.

Hand, foot and mouth disease prevention

Cut off the source of infection

Cut off the transmission route

Protect vulnerable groups

rubella

Rubella is caused by the rubella virus. It is also called "rheumatism" because the rash is as small as sand. It and measles are two completely different infectious diseases. It starts out like a cold, with a body temperature of around 38 degrees Celsius. Generally, a light red rash appears on the skin 1-2 days after the fever. The rash is small and sparsely distributed, and disappears naturally in about 3 days. It is characterized by enlarged lymph nodes behind the ears and behind the occipital gland. If pregnant women are infected with this disease in early pregnancy, it can cause fetal malformations.

Precaution

1. Health education. Both overt and latent rubella infections are harmful to the fetus in early pregnancy. The focus is on preventing infection in pregnant women, especially in the first 3 months of pregnancy.

2. Immunization. Use a live attenuated rubella vaccine. The effective immunity lasts for 5-8 years. The vaccine needs to be transported and stored under refrigerated conditions. Immunosuppressed people and pregnant women are contraindications to the vaccine.

Measures during the epidemic period focus on the three links of infection source, transmission route and susceptible groups. The key measures are emergency vaccination. The key groups are school-age children, pre-adolescent women, medical personnel and military recruits. The main means of transmission are to maintain air circulation and air disinfection in public places.

measles

Measles is an acute respiratory infectious disease caused by the measles virus. Measles is mainly spread through droplets or direct contact with a patient's nose and throat secretions. The population is generally susceptible. The incubation period for measles is 7-18 days, usually 14 days. There is lasting immunity after recovery. Measles is most common in winter and spring, but it can occur throughout the year.

The main clinical manifestations are cough, runny nose, fever, red eyes, and white spots in the mouth (Kopi's leukoplakia) in the early stage of infection; 3-7 days later, a maculopapular rash will appear on the skin, usually spreading from the face to the whole body and lasting for 4-7 days. It may last up to 3 weeks, leaving brown stains or scaling; in severe cases, the respiratory system, digestive system and brain will be affected, leading to serious consequences and even death.

Precaution

The transmission route of measles is difficult to control. Most susceptible people have been infected before the patient is isolated, so the isolation of the patient can only play a general role. The focus is on improving immunity in susceptible populations.

Immunization (1) Passive immunity: Gamma globulin and placental globulin can prevent measles in the short term. Early injection of contacts can prevent the disease, but later injection can only reduce the disease. Injections are ineffective after 6 days of exposure to the measles virus. (2) Automatic immunization: The measles immunization strategy in my country is set as early vaccination at the age of 8 and repeated vaccination at the age of 7. Immunosuppressed persons and pregnant women are contraindications to the vaccine.

Measures during the epidemic period: The main means of transmission are to maintain air circulation and disinfection in public places. The key measure is to provide emergency vaccination to susceptible people within a certain age range as early as possible to block the epidemic.
