Information

1

Who is susceptible to novel coronavirus?

The crowd is generally susceptible.

Novel coronavirus pneumonia can occur in both immunocompromised and immunonormally infected people, and is related to the amount of virus exposure.

For people with poor immune function, such as the elderly, pregnant and pregnant women, or those with abnormal liver and kidney functions, who have chronic diseases, the disease is worse after infection.

2

What are the ways of transmission of a novel coronavirus?

The main modes of transmission are transmission by droplets, contact transmission (including self-inoculations caused by hand contamination) and close transmission of respiratory aerosols of different sizes.

At present, close - range droplet transmission should be the main way.

3

Can a novel coronavirus be passed from person to person?

Will be.

Judging from the incidence sequence of some clustered cases, the characteristics of human-to-human transmission are very obvious, and there is a certain range of community transmission.

4

What is droplet transmission?

Droplets: water-bearing particles with a diameter of > 5um are generally considered. Droplets can enter susceptible mucosal surfaces through a certain distance (generally 1 meter).

Droplet production:

(1) cough, sneeze or talk

(2) perform invasive operations of respiratory tract, such as sputum aspiration or endotracheal intubation, roll over, pat on the back, etc., and cardiopulmonary resuscitation.

5

What is contact transmission?

Direct contact: transmission of pathogens by direct contact with mucous membranes or skin

(1) blood or bloody fluids enter the body through mucous membranes or damaged skin

(2) direct contact with secretions containing certain pathogens causes transmission

6

What is a close contact?

A person who has lived or worked with a confirmed or highly suspected case of the virus within 14 days.

Including colleagues in the office, colleagues in the same classroom, dormitory, classmates, passengers on the same plane, etc.

And other forms of direct contact include escorts of infected patients, taxis and elevators.

7

Precautions for close contacts

All people (including health care workers) who may have had contact with a suspected patient should be given a 14-day health watch.

The observation period begins on the last day of contact with the patient.

As soon as any symptoms appear, especially fever, respiratory symptoms such as cough, shortness of breath or diarrhea, seek medical advice immediately!

8

Close contact monitoring recommendations

(1) if the contact shows symptoms, inform the hospital in advance and will go to the hospital.

(2) patients should wear surgical masks on the way to the hospital.

(3) avoid public transport, call an ambulance or use a private vehicle to transport the patient. If possible, open the window on the road.

(4) close contacts who are ill should maintain respiratory hygiene and clean hands at all times.

When standing or sitting on the road or in the hospital, keep as far away from others as possible (at least 1 meter).

(5) any surfaces contaminated by respiratory secretions or body fluids should be cleaned and disinfected with a disinfectant containing diluted bleach.

9

What are the clinical manifestations of novel coronavirus pneumonia patients?

Novel coronavirus infection of pneumonia with fever as the main manifestation, can be combined with mild dry cough, fatigue, dyspnea, diarrhea and other symptoms, runny nose, cough and sputum symptoms are rare.

Some patients have mild symptoms, but no fever, only symptoms of headache, palpitation, chest tightness, conjunctivitis, mild limb or back muscle pain.

Some patients developed dyspnea after a week, and the severe cases progressed rapidly.

Most of the patients had a good prognosis, and a few were in critical condition or even died.

10

How to identify and observe a case of pneumonia caused by novel coronavirus in clinical practice

At the same time meet the following two conditions

(1) epidemiological history: in the two weeks before the onset of the disease, the travel or residence history in wuhan city, or the 14 days before the onset of the disease, the exposure to the patients with fever from wuhan accompanied by respiratory symptoms, the prevalence of residential infectious diseases, whether the patients in the cluster cases, whether the infection caused by others, etc.

Direct or indirect contact with relevant markets, especially farmers' markets in wuhan.

(2) clinical manifestations: fever;

Viral pneumonia imaging features;

The total number of white blood cells in the early stage of the disease is normal or decreased, or the lymphocyte count is reduced.

On the basis of case observation, collecting sputum, pharyngeal swab and other respiratory tract specimens for viral nucleic acid detection can be used to make etiological diagnosis.

11

Prevention and control measures of pneumonia by novel coronavirus

• standard precautions;

• precautions against airborne transmission;

• contact and droplet precautions: wash hands frequently and wear a mask when going out;

• room ventilation;

• cleaning and disinfection: novel coronavirus is sensitive to heat. Soaking in hot water at 56℃ for 30 minutes, 75% alcohol, chlorine-containing disinfectant, chloroform and other fatty solvents can effectively inactivate the virus.

Global Trade Resumption and Shipping Industry Challenges: An Overview
Global Trade Resumption and Shipping Industry Challenges: An Overview
As global trade activities gradually recover, the shipping industry is experiencing unprecedented shipping space shortages. Concurrently, shipping prices are showing significant upward trends, posing a crisis and challenge to the global supply chain. Crisis in the Global Supply Chain, Skyrocketing Shipping Costs This year, influenced by multiple factors such as escalating geopolitical tensions and regional conflicts, the global supply chain has fallen into a severe crisis. On one hand, the conflict in the Red Sea has affected the navigation through the Suez Canal. In response to blocked routes, a large amount of cargo has chosen to detour around the Cape of Good Hope. This not only significantly increased transportation costs and delayed delivery times but also increased carbon emissions. For instance, for a large container ship (with a capacity of 20,000-24,000 TEU) on the Far East to Europe route, if it detours around Africa, the additional emission costs calculated by the EU Emissions Trading System (ETS) for each voyage can reach as high as $400,000. To cope with the increase in transportation costs, many shipping companies have adjusted their freight rates, leading to a rise in shipping prices. On the other hand, the congestion and strikes at some European and American ports have resulted in large-scale sailing cancellations for European and American routes. According to Drewry’s data on canceled voyages, from September 30 to November 3, 2024, 100 voyages were announced canceled on the main east-west routes—trans-Pacific, trans-Atlantic, and Asia-Northern Europe and Mediterranean routes. The total number of canceled voyages accounted for 14% of the planned 693 voyages. The increase in the proportion of canceled voyages and the undiminished transportation demand led to severe overbooking and cargo rollovers starting in mid- to late October. According to the “China Export Container Transportation Market Weekly Report” released by the Shanghai Shipping Exchange on November 9, overbooking occurred on routes to North America, South America, Europe, and Southeast Asia at the end of October, with some routes extending to November. This situation also led to rising shipping prices. The report showed that on November 8, the market freight rates (including ocean freight and ocean surcharges) from Shanghai to the basic ports of Europe and the Mediterranean were $2,541/TEU and $3,055/TEU, respectively, up 4.1% and 5.1% from the previous period. The Shanghai Shipping Exchange’s Shanghai (SCFI) on November 8 was 2,331.58 points, up 1.2% from the previous period, marking the third consecutive week of increase, approximately 13% higher than the low on October 18. The skyrocketing shipping prices have not only brought tremendous pressure to the global logistics and supply chain but also further complicated the global transportation and trade network. High Freight Rates Likely to Persist Until the End of the Year To cope with market changes and alleviate the pressure of insufficient capacity, ensuring the stability and sustainability of transportation services, several globally renowned shipping companies such as Hapag-Lloyd, Hyundai Merchant Marine (HMM), and Maersk have recently announced new freight rate adjustment plans and notices for peak season surcharges. Hapag-Lloyd announced on October 30 that it would increase the FAK rates on the Far East to Europe route, effective from November 15, 2024. Hyundai Merchant Marine (HMM) announced in a customer notice that, starting from December 1, 2024, it will implement GRI (General Rate Increase) for all services from origin to the United States, Canada, and Mexico. Maersk recently announced that it will impose peak season surcharges (PSS) on routes to Australia, Papua New Guinea, Solomon Islands, and other destinations. At the same time, it will impose peak season surcharges on routes to Africa to address the ongoing tensions in the global shipping market. By adjusting freight rates and imposing surcharges, a certain balance between supply and demand can be achieved, ensuring the normal operation of shipping businesses, but it also unintentionally pushes up the price of the entire maritime market. At the same time, affected by festivals such as Thanksgiving and Christmas, the transportation demand on the European route remains high, which will continue to drive up the spot market freight rates. Therefore, shipping prices may continue to rise before the end of the year. Whether future freight rates can significantly fall mainly depends on the trends of geopolitical conflicts such as the Red Sea crisis and international situations. The increase in shipping prices is undoubtedly a good thing for shipping companies, but for enterprises, it will not only increase their transportation costs but may also affect the efficiency and cost structure of global trade activities. Especially for manufacturing and retail industries that rely on multinational supply cha
