In the face of the COVID-19, how to ensure the medical services of key groups has attracted much attention. How do the elderly perform home treatment? How to care for infants after infection? What are the necessary preparations for patients with respiratory diseases? The joint prevention and control mechanism of the State Council held a press conference on the 20th to respond to relevant hot issues. The elderly should pay attention to avoid infection. Most children have a self limited course of disease. "The elderly must be well protected." Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, said, especially the elderly with basic diseases and the elderly without vaccination. These people belong to serious high-risk groups, and special attention should be paid to avoid infection. Should the elderly use antiviral drugs in case of infection? "At present, most people are mild or asymptomatic after infection, but early intervention is still needed for people with high risk of severe infection." Wang Guiqiang said that several antiviral drugs were recommended in the ninth edition of the diagnosis and treatment plan, including monoclonal antibodies, combined packaging of Nematovir/Litonavir tablets and Azovudine. "Antiviral treatment can shorten the course of the disease and reduce the risk of severe disease, but antiviral drugs should be used under the guidance of doctors and should not be used casually at home." Wang Guiqiang said, for example, there is a problem of drug interaction between nematevir. The elderly and those with underlying diseases often take a variety of drugs orally, such as simvastatin, amiodarone, etc., so nematevir cannot be used. "Medical institutions and communities will gradually provide corresponding antiviral drugs, so that infected people, especially those with high risk of severe illness, can use them reasonably under the guidance of doctors," said Wang Guiqiang. Children are the people we focus on protecting. If children are infected, how should they be treated and cared for at home? Wang Quan, director of the emergency department of Beijing Children's Hospital, said that after infection with COVID-19, children's main symptoms were fever, cough, nasal congestion, runny nose, sore throat, etc. Some children may have muscle soreness, fatigue, vomiting and diarrhea, and some children may also have hoarseness and other laryngitis. "Because most children have a self limited course of disease, we should mainly deal with the symptoms by improving the comfort of the children and relieving the symptoms." Wang Quan said that when children have a fever, on the one hand, they should not cover the heat, on the other hand, they should avoid getting cold again. Wang Quan introduced that the only antipyretic drug available to children over 2 months and under 6 months is acetaminophen; Children under 2 months old cannot take antipyretic drugs orally. Children under 2 months old, including newborns, should go to the hospital in time if they have fever. A few children may have febrile convulsions during the course of the disease. Wang Quan said that once a febrile convulsion occurs, the child should be placed on a flat and not easily injured floor or bed, the collar of the child should be loosened, the respiratory tract should be unobstructed, the child's head should be turned to one side, and if possible, the child should be kept in a right side position. When a convulsion occurs, do not put anything in the child's mouth, do not feed anything, and do not try to bind the child's limbs, so as not to cause damage to the child's limbs. "Most children have febrile seizures in a short time, usually stopping within 3 to 5 minutes. If the child has had a state of convulsion or this seizure before
