Introduction

Hantavirus primarily causes hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). The main transmission routes include: respiratory transmission, where aerosols formed from dust contaminated by excreta (such as urine, feces, and saliva) of rodents carrying hantavirus can infect humans via the respiratory tract; and digestive tract transmission, where ingestion of food or water contaminated by rodent excreta may lead to hantavirus infection through the digestive tract.

Hantavirus is generally transmissible. If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analysis is as follows:

Hantavirus primarily causes hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Transmission routes of hantavirus include respiratory transmission, digestive tract transmission, and direct contact transmission. Aerosols formed from dust contaminated by excreta (such as urine, feces, and saliva) of virus-carrying rodents can infect humans via the respiratory tract. Consumption of food or water contaminated by rodent excreta may lead to infection through the digestive tract. Infection may also occur through rodent bites or direct contact of broken skin or mucous membranes with infected rodent excreta or secretions. Additionally, there have been rare reports of mother-to-child transmission, although this is uncommon.

Humans are generally susceptible to hantavirus. In endemic areas, individuals engaged in outdoor work, agricultural labor, and similar activities face relatively higher risks of infection. After infection, disease severity varies; mild cases may present only with fever, headache, and muscle pain, while severe cases can develop serious complications such as shock and acute kidney failure, potentially leading to life-threatening conditions.

Individuals should take preventive measures against infection, including rodent control and prevention, maintaining personal hygiene, and avoiding contact with rodents and their excreta.

头晕恶心是食物中毒吗

After consuming suspicious foods—such as expired products, undercooked meat, or contaminated fruits and vegetables—symptoms such as dizziness and nausea may appear within minutes to several hours, often accompanied by vomiting, abdominal pain, diarrhea, and fever. Some individuals may also experience dehydration and fatigue, with severe cases potentially leading to confusion. These symptoms are typically indicative of food poisoning, caused by bacteria, viruses, or toxins in the food irritating the gastrointestinal tract.

If a dog bites but doesn't cause bleeding, is it necessary to get a shot?

Scratches, abrasions, or faint tooth marks on the skin may indicate minor wounds, even if there is no bleeding. A dog's saliva may carry the rabies virus, which can enter the body through these breaks in the skin and cause infection. Such cases require prompt wound treatment, vaccination, and, when necessary, administration of rabies immunoglobulin to prevent the virus from incubating and progressing.

What is the principle of anesthesia?

Under normal circumstances, anesthesia works by using drugs or physical methods to act on the nervous system, blocking the transmission of pain signals, suppressing central nervous system functions, or inhibiting local nerve responses. This renders the body insensible to pain, consciousness, or localized sensation during medical procedures such as surgery, while maintaining stable vital signs. In addition, parameters such as heart rate, blood pressure, and blood oxygen saturation must be closely monitored throughout the anesthesia process.

Is monkeypox DNA or RNA?

In general, monkeypox virus is a DNA virus. In daily life, precautions should be taken to avoid contact with animals that may carry the monkeypox virus, as well as their secretions and excretions. If one has been exposed to individuals with monkeypox or potentially contaminated items, prompt personal hygiene and disinfection are essential. If symptoms such as fever or rash—suggestive of monkeypox—increase, immediate medical attention should be sought, and exposure history must be disclosed to prevent further spread of the virus.

How is influenza A transmitted?

In general, influenza A is mainly transmitted through respiratory droplets, close contact, airborne aerosols, contact with contaminated objects, and mother-to-child transmission. It is recommended to take proper personal protective measures in daily life, wear masks correctly when going out, and avoid crowded places. Wash hands frequently with soap or handwash and running water.

What happens if onychomycosis is left untreated?

In general, if left untreated, onychomycosis (fungal nail infection) can have various adverse effects on the nail itself, surrounding skin, and overall health, and may also impact daily life. Therefore, prompt treatment is recommended once onychomycosis is detected, to prevent worsening of the condition or transmission to others. During treatment, it is important to follow medical advice regarding medication, maintain good personal hygiene, and avoid sharing personal items with others to enhance treatment effectiveness.

Can hepatitis B virus cause fetal malformations?

The hepatitis B virus itself usually does not directly cause fetal malformations; its primary risk is transmitting the virus to the fetus. To reduce the risk of mother-to-child transmission, pregnant women who are hepatitis B surface antigen positive should receive antiviral interventions under medical guidance, including appropriate use of antiviral medications during pregnancy and timely administration of hepatitis B immunoglobulin and the first dose of hepatitis B vaccine to the newborn after birth.

Are hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) positive results infectious?

HBsAg negative, anti-HBs positive, HBeAg negative, anti-HBe negative, and anti-HBc positive (i.e., positive for the second and fifth markers) usually indicates no infectivity. This result suggests a past hepatitis B virus infection that has resolved, with development of immunity against hepatitis B. Individuals with positivity only for the second and fifth markers do not need to worry about transmitting the virus and require no special treatment. It is recommended to periodically check the titer of hepatitis B surface antibody; if the titer drops below the protective level, appropriate measures such as booster vaccination may be considered.
